Ablation technologies are used to destroy ("ablate") diseased or traumatized tissue for therapeutic benefit. This includes destruction of cancerous tumors, ablation of endometrial tissue associated with endometriosis or abnormal uterine bleeding, creation of myocardial lesions to block the errant electrical signals in arrhythmia, and numerous others.
The largest share of the market for energy-based ablation devices is used in cancer therapy, primarily using the radiation therapy modality. Following that is general surgery with its use of electrocautery and electrosurgical devices, RF ablation, cryotherapy, etc. Cardiovascular applications are growing, particularly for cryoablation and radiofrequency ablation for arrhythmia, and now represent hold the third largest clinical area of ablation. The remaining applications are relatively small and fall in line behind the three leading sectors.
In the aggregate (i.e., for each modality worldwide), the largest segment is radiation-based ablation technologies, based to a large degree on the cost of the systems and their well-established use in clinical practice.
Below is a chart of the 2011 markets for ablation technologies by modality, with their projected compound annual growth rates (CAGRs) from 2011 to 2019.
