Growth in Sealants, Glues, Hemostats, and Wound Closure is Absolute, Relative

Of late, I have needed to re-emphasize the difference between absolute and relative growth in medtech markets (and its importance). So, here it is again, this time regarding surgical sealants and other wound closure products.

The lowest relative rate of growth in this industry is the well-established sutures and staples segment. Sales of these products globally, even supported by innovations in bioresorbables and laparoscopic delivery technologies, are only growing at a 5.6% compound annual growth rate from 2013 to 2018. By comparison, growth of sales of surgical glues and sealants is at 9.4% for 2013-2018.

But from an absolute sales growth point of view, sales of sutures and staples will go from $5.2 billion to $6.9 billion, or absolute growth of $1.7 billion. Simultaneously, the relatively high growth in surgical glues and sealants translates to the absolute growth from 2013 to 2018 of only $0.9 billion.

Obviously, both absolute and relative growth are of interest.

Bioactive Agents in Wound Sealing and Closure

Excerpt from Report #S192, “Worldwide Surgical Sealants, Glues, and Wound Closure 2013-2018”.

Screen Shot 2015-03-30 at 10.14.59 AMBiologically active sealants typically contain various formulations of fibrin and/or thrombin, either of human or animal origin, which mimic or facilitate the final stages of the coagulation cascade. The most common consist of a liquid fibrin sealant product in which fibrinogen and thrombin are stored separately as a frozen liquid or lyophilized powder. Before use, both components need to be reconstituted or thawed and loaded into a two-compartment applicator device that allows mixing of the two components just prior to delivery to the wound. Because of the laborious preparation process, these products are not easy to use. However, manufacturers have been developing some new formulations designed to make the process more user friendly.

Wound Sealant and Securement Procedure Volumes by Clinical Area and End-Point

Sealants, glues, hemostats, and other products in wound closure and securement offer benefits that vary by clinical area, but the nature of that benefit also varies by the type of end-point (benefit) the product achieves — does it provide a life-saving benefit? A time-saving? Cost-savings? A cosmetic or aesthetic benefit?

Accordingly, by examining the volume of procedures for which closure and securement products provide which kind of benefit is crucial to understanding demand, especially between competitive products.

Below is a categorization of benefits ranging from the critical (I) to the aesthetic (IV).

Classification of Wounds by Morphology

Wounds may be classified according to their depth and whether underlying tissues are damaged. Partial-thickness wounds do not intrude through the dermis and can heal by regeneration; full-thickness wounds involve both the epidermis and dermis, and sometimes underlying tissues as well. They generally heal by scar formation. Wound classification by morphology is shown below:

TypeTissue CharacteristicsEtiologyPrognosis for Healing
Partial thicknessInvolves entire epidermis and portions of dermis.Friction, pressure, small cuts, minor burns.Heal within 10-18 days, epidermal element germinates and migrates up to the epithelial layer. Heals without significant scarring or functional impairment.
Deep partial thicknessInvolves entire epidermis and almost entire dermis.Friction, cuts, significant burns.Healing within 20-35 days.
Full thicknessInvolves epidermis and dermis; may extend into subcutaneous tissue. Sweat glands and hair follicles are destroyed.Severe deep cuts, surgical incisions, most chronic wounds, and third-degree burns.Heals by granulation, formation of new blood vessels, new biomaterial deposition, and new cells over many weeks. Scarring usually results.
Underlying tissue damageConsidered more extensive than full- thickness wounds. Involves subcutaneous tissue, muscle, fascia, bone, and other organs.Surgery of organs, electrical burns and certain thermal burns, such as molten metal or severe scalding, massive traumatic injury, and untreated chronic damage.May require debridement or removal of all necrotic tissue to expose viable bleeding tissue. Systemic antibiotic therapy and grafts/flap skin replacement.

Manufacturers of sealants, glues, hemostats

Sealants and glues also are emerging as important adjunctive tools for sealing staple and suture lines, and some of these products also are being employed as general hemostatic agents to control bleeding in the surgical field. Manufacturers have also developed surgical sealants and glues that are designed for specific procedures – particularly those in which staples and sutures are difficult to employ or where additional reinforcement of the internal suture/staple line provides an important safety advantage.

Surgical sealants are made of synthetic or naturally occurring materials and are commonly used with staples or sutures to help completely seal internal and external incisions after surgery. In this capacity, they are particularly important for lung, spinal, and gastrointestinal operations, where leaks of air, cerebrospinal fluid, or blood through the anastomosis can cause numerous complications. Limiting these leaks results in reduced mortality rates, less post-operative pain, shorter hospital stays for patients, and decreased health care costs.

Although some form of suturing wounds has been used for thousands of years, sutures and staples can be troublesome. There are procedures in which sutures are too large or clumsy to place effectively, and locations in which it is difficult for the surgeon to suture. Moreover, sutures can lead to complications, such as intimal hyperplasia, in which cells respond to the trauma of the needle and thread by proliferating on the inside wall of the blood vessel, causing it to narrow at that point. This increases the risk of a blood clot forming and obstructing blood flow. In addition, sutures and staples may trigger an immune response, leading to inflamed tissue that also increases the risk of a blockage. Finally, as mentioned above, sutured and stapled internal incisions may leak, leading to dangerous post-surgical complications.

These are some of the reasons why surgical adhesives are becoming increasingly popular, both for use in conjunction with suture and staples and on a stand-alone basis. As a logical derivative, surgeons want a sealant product that is strong, easy-to-use and affordable, while being biocompatible and resorbable. In reality, it is difficult for manufacturers to meet all of these requirements, particularly with biologically active sealants, which tend to be pricey. Thus, for physicians, there is usually a trade-off to consider when deciding whether or not to employ these products.

Surgical sealants, glues, and hemostats can be divided into several different categories based on their primary components and/or their intended use. For the purposes of this analysis, the market is broken down by composition into products containing biologically active agents, products made from natural and synthetic (nonactive) components, and nonactive scaffolds, patches, sponges, putties, powders, and matrices used as surgical hemostats. The market for sealants, glues, and hemostats, while largely controlled by J&J/Ethicon and Baxter, nonetheless has many active players, many of whom have demonstrated staying power (and growing share) in the global market.

Below is illustrated the manufacturers in bioactive products, non-active natural or synthetic agents, and non-active materials.

Absolute and Relative Growth in Wound Closure Product Sales Worldwide

Medtech manufacturers interested in “growth” markets need to consider the relative versus absolute. Nascent markets can growth from $1 million sales in year 1 to $2 million in year 2, obviously a 100% increase. But in multi-billion markets, a $1 million increase will elicit a yawn from all but the smallest manufacturers.

Just as an exercise, I ranked the growth rates for sales of wound closure products detailed in our Report #S192 by both the absolute sales growth from 2014 to 2018 and the compound annual growth rate over this period. To reveal the differences even further, I did this ranking by the all combinations of geographic area and wound closure product type. Partial results — just the top growth rankings, since the list is too long to show all — are shown side by side below (click on the chart to see a more legible version).

Even though tapes, sutures and staples have very modest growth rates in many geographic markets, their current dollar volume sales make such growth much more significant in absolute terms.

Sealants, Glues, Hemostasis and Wound Closure Market, Size and Growth

The simple practice of closing wounds is not so simple, driven as it is by the fact that wounds can be the conduit for blood, infectious agents and every other liquid, gas or solid that should not enter or exit the wound.  The closure has to be readily accomplished, regardless of where the wound exists. The closure should not only prevent blood from being lost but ideally should actively stop the bleeding. The wound must stay closed despite the pressures exerted upon it. The closure should also have a minimal “footprint”, with the closure components being easily removed, absorbed or otherwise leaving the least possible trace of the closure, including scar tissue.

Hence, tapes, staples, sutures, clips, hemostatic agents, sealants, glues and other devices have been developed to get the job done.  The market for this range of closure options now reflects biologics, absorbable materials, devices and other products. Fundamentally, the market remains largely dominated by sutures and staples/clips, which have satisfied the demands of internal/external closure, easy of use, low cost, strength of closure and other considerations, not least of which is the evolving nature of surgical practice from the “open” to endo/laparoscopic. Nonetheless, tighter wound sealing, less bleeding and better outcomes in general have driven manufacturers to develop improvements.

Below is illustrated the 2014 market for the range of wound closure products along with their associated growth rates. The prospects for medical/surgical tapes are the exception to the rule, demonstrating a steady decline while better alternatives demonstrate steady growth.

Synthetic Surgical Sealants

This is an excerpt from Report #S192, “Worldwide Surgical Sealants, Glues, and Wound Closure Markets, 2013-2018”, published by MedMarket Diligence, LLC.

Compared to biologically active sealants containing fibrin and other human- or animal-derived products, synthetic sealants represent a much larger segment of the sealant market in terms of the number of competitors, variety of products, and next-generation products in development. Non-active synthetic sealants do not contain ingredients such as fibrin that actively mediate the blood clotting cascade, rather they act as mechanical hemostats, binding with or adhering to the tissues to help stop or prevent active bleeding during surgery.

Synthetic sealants represent an active category for R&D investment in large part because they offer several advantages over fibrin-based and other biologically active sealants. First and foremost, they are not derived from animal or human donor sources and thus eliminate the risks of disease transmission. Moreover, they are typically easier to use than biological products, often requiring no mixing or special storage, and many of these products have demonstrated improved sealing strength versus their biological counterparts. Synthetic products also have the potential to be more cost-effective than their biologically active counterparts.

Leaders in the synthetic surgical sealants space include Baxter International Inc., CryoLife, CR Bard, and Ethicon/J&J; however, there are many up-and-coming competitors operating in this segment of the market with some interesting next-generation technologies that could gain significant traction in the years ahead. Moreover, unlike the fibrin sealants segment, where most products have more general indications for surgical hemostasis, a good number of competitors in the synthetic sealant field are focused on specific clinical applications for their products, such as cardiovascular surgery, plastic surgery, or ophthalmic surgery.

Sealants/Glues, Hemostats, Other Wound Closure Markets, Size and Growth

Products in wound closure include sutures/staples, tapes, vascular closure devices, surgical hemostats, and surgical sealants/glues.

Wound types have not changed over history, with a slight exception being the emergence (several decades ago) of femoral punctures associated with catheterization procedures. But what has changed, and what continues to evolve, is the practice of closing those wounds. Sutures, staples and tapes are a mainstay of medical practice, representing uncomplicated methods to secure wounds. And while innovators continue to change the form and function of these products to improve performance, the more recently introduced surgical hemostats, vascular closure, and surgical sealants/glues have seized significant shares of wound closure caseload and are growing marginally faster than sutures/staples and tapes. The result is and will be an erosion of traditional wound closure technology shares.

Below is illustrated the size/growth of segments in the global wound closure market.

Surgical Glues, Sealants, Hemostats and Wound Closure Worldwide Markets

Acute wounds have long represented a core focus of healthcare, one that manufacturers have been steadily changing through innovative new technologies. MedMarket Diligence’s global report on wound closure markets reveals the dynamics of this change, detailing the clinical practices, products, technologies, companies and the resulting current and forecast markets.

PRLogApril 7, 2015MISSION VIEJO, Calif.The products and technologies focused on the management of acute wounds, encompassing hemostasis, closure and sealing represent a significant, growing segment of the total medical device market. The global market for surgical sealants, glues, and wound closure devices reached over $10.8 billion in 2014 and is forecast to increase to about $14 billion in 2018, exhibiting an overall compound annual growth rate (2014-2018) of 7.0%, according to the latest global report on wound closure and related products, published by MedMarket Diligence.

“We have tracked this market as manufacturers introduced novel wound sealing and closure technologies intended to integrate with one of the highest volume areas of healthcare,” says Patrick Driscoll, President of MedMarket Diligence. According to Driscoll, the level of innovation has been remarkable — from the advent of fibrin glues, to the continued evolution of sutures and staples, to the emergence of products working alone or in tandem to achieve better outcomes in a cost sensitive climate.This market is comprised of sutures/staples, vascular closure devices, surgical tapes, surgical hemostats, and surgical sealants and glues. There are well over 100 companies active in the marketing and development of these products, with the associated technologies running the gamut from devices to biologics to synthetics.

Wound closure has become a clinical practice that is rapidly evolving from what was once simple suturing or taping wounds to more sophisticated procedures that ensure rapid cessation of blood loss, prompt closure, strong adhesion of wound edges, tight sealing, reduced scarring, reduced risk of infection and more rapid healing — all accomplished largely with existing surgeon skills and with reasonable costs for healthcare payers and margins for manufacturers.

Surgical sealants and glues are expected to demonstrate the highest growth rate over the forecast period, but the largest segment in terms of revenues is the sutures and staples market, which comprise about half of the worldwide total. Hemostats represent the next largest segment, followed by surgical sealants and glues, tapes, and vascular closure devices.

The market leaders in this area are Johnson & Johnson, Covidien, B. Braun, and 3M, but market shares have proven to be fluid as innovations from hundreds of competitors are gaining and expanding footholds in the big companies’ territories.

The MedMarket Diligence report, “Worldwide Surgical Sealants, Glues, and Wound Closure Markets, 2013-2018“, provides specific forecasts and shares of the worldwide market by segment for Americas (detail for U.S., Rest of North America and Latin America), Europe (detail for United Kingdom, German, France, Italy, Spain, Rest of Europe), Asia/Pacific (detail for Japan, Korea, Rest of Asia/Pacific) and Rest of World.

The report also provides background data on the surgical, disease and traumatic wound patient populations targeted by current technologies and those under development, and the current clinical practices in the management of these patients, including the dynamics among the various clinical specialties or subspecialties vying for patient population and facilitating or limiting the growth of technologies.

The report establishes the current worldwide market size for major technology segments as a baseline for and projecting growth in the market through 2018. The report also assesses and projects the composition of the market as technologies gain or lose relative market performance over this period.

The report profiles the top companies by revenue and a reasonable selection of the most promising or otherwise noteworthy companies in the markets covered in this report, providing data on their current products, current market position and products under development.
