Implant with textured surface
First Claim
1. An implantable medical device for implanting into soft tissue of a mammal, said implantable device comprising a supporting structure, said supporting structure having an outer surface for interface with the soft tissue and a plurality of fin projections extending from said outer surface, said plurality of fin projections forming a textured exterior surface over at least a portion of said implantable device, each fin projection having a length substantially greater than its width, said fin projections being arranged in a pattern so as to create a sinuous path for collagen formation around the device and to substantially eliminate straight-line paths for collagen formation around the device.

Abstract
An implantable medical device is disclosed. The device has a plurality of fin projections extending from the outer surface of the device, forming a textured exterior surface over at least a portion of the device. Each fin projection has a length substantially greater than its width, the fin projections being arrayed in a basket weave-like, herringbone-like, or other suitable pattern to create a sinuous path for collagen formation around the implanted device. Uses include as a prosthesis, mammary implant, drug mass transport device, and sensor device.
