Method of making a composite biotextile and a medical implant comprising such composite biotextile |
| abstract |
Disclosed herein is a method of making a composite fabric for use in or as a medical implant component, the method comprising steps of providing a textile comprising at least one strand having titer of 2-250 dtex and comprising fibers made from a biocompatible and biostable synthetic polymer; determining locations on the textile where a cut is to be made for an intended use of the textile; optionally pretreating the textile at least at the determined locations on at least one side of the textile with a high-energy source to activate the surface; solution coating the textile at least at a determined location with a coating composition comprising a biocompatible and biostable polyurethane elastomer and a solvent for the polyurethane; removing the solvent from the coated textile; and laser cutting the coated textile as obtained at least a one coated location with an ultra-short pulse laser; to result in a composite biotextile wherein polyurethane is present in an amount of 2.5-90 mass% based on composite biotextile and polyurethane is present at least at a laser-cut edge. Such composite biotextile as made shows an advantageous combination of good biocompatibility, especially hemocompatibility, high strength and pliability, and has well-defined regular edges that have high suture retention strength. Further embodiments concern the use of such composite biotextile in or as medical implant component for an implantable medical device; such as in orthopedic applications and cardiovascular implants. Other embodiments include such medical devices or implants comprising said composite biotextile or medical implant component. |
