Post-surgical adhesions occur almost any time a surgeon opens up a body cavity; in intra-abdominal surgery, for example, they form 85-90% of the time. But after a decade of trying, the medical device industry has only two adhesion prevention products to show for its efforts, and both products have drawbacks that have limited their market penetration. A new generation of companies--Confluent Surgical, Angiotech Pharmaceuticals, FzioMed, Sentrx Surgical, Afmedica, Kytogenics Pharmaceuticals, and ARC Pharmaceuticals, hope to profit from years of learning in the field to get new and improved products into the hands of surgeons .
