In part one of our series, it was described why material choice is an important consideration when developing surgical meshes for rotator cuff repair. Materials impact the strength and stretch resistance of the implant, ability to hold a suture, ability to be delivered arthroscopically, ability to be terminally sterilized, and even the desired degree of biocompatibility and integration of the device. Another important consideration is the ability to meet the stringent requirements of FDA and other regulatory bodies. Surgical mesh used for rotator cuff repair can be made of natural materials or synthetic materials – each with certain advantages. One of the biomaterials mentioned in the previous article was a non-resorbable synthetic Thermoset Polyurethane called Biomerix™ PCPU. In this second part of our series, we will focus on this unique material and its properties that make it ideal for use in rotator cuff repair devices.
