The tissue closure and securement market can be regarded as a benchmark indicator for overall expansion of medical device usage. This is because surgical closure and securement products are growing to be components of all surgical procedures. These products are used for rapid and efficient closure of surgical wounds, and internal securement of tissues to reduce pain and accelerate rehabilitation. Appropriate use of these products can reduce risk of infection, and can optimize the repair process to enhance the speed and strength of tissue repair, as well as reducing complications such as those resulting from post-surgical adhesions. Below are definitions for the products in the field of surgical closure and securement.
Definition of Surgical Closure and Securement Products
Sutures are medical devices made out of woven or single filament fibers of steel, synthetic polymer or natural biomaterials that are used to secure cuts, lacerations, and incisions in the surface or internal tissues.
Staples are rigid or semi-rigid suture-like materials delivered through a closure device and consisting of single- or multi-filament fibers of steel, synthetic polymer or natural biomaterials that are used to secure cuts, lacerations, and incisions in the surface or internal tissues.
Tapes are fabric and polymer-based medical devices that are used to secure cuts, lacerations, and incisions in the surface of the skin as an adjunct to wound closure.
A hemostat reacts in the presence of blood to establish the normal cascade of factors that arrest bleeding. These products can be added to a bleeding field during surgery to prevent further bleeding, and are mostly dependent on a full complement of normal factors in the patient’s blood.
A sealant will prevent leakage of fluid and/or gas from a surgical incision (such as pulmonary gases or spinal fluids). These products will often hold back pressurized fluids from normal vascular activity. Although their efficiency does not normally require the full complement of active clotting factors in blood to be within normal levels, these products (e.g., fibrin sealants) normally also have some hemostatic activity.
Glues and adhesives (e.g., cyanoacrylate glues) are used to attach organs, structures, or tissues to each other or to effect repair. These materials can be enhanced by incorporating additional hemostatic or sealant properties, such as Angiotech’s Vitagel (a combination of collagen and thrombin) and Nycomed’s Tachocomb (a combination of thrombin, collagen and fibrin).
Abnormal joining of two organs or tissues occurring after inflammation, especially post-surgery. Adhesion-prevention or anti-adhesion products are medical devices or substances made from synthetic polymer or natural biomaterials that are manufactured into gels, fabrics, films, and dried solids that when applied to internal tissue surfaces limit the formation of post-surgical adhesions (PSA).
