Tissue-connective devices with micromechanical barbs

摘要

A system for linking a first member with a second member. The system is comprised of a first plurality of micromechanical barbs disposed on the first member. The system is also comprised of a second plurality of micromechanical barbs disposed on the second member. The barbs on the first member and the second member are of a shape such that a locking connection is formed between the first member and second member through the first plurality and second plurality of barbs when placed together. Each of the barbs of the first plurality and second plurality of barbs extend from the first member and second member, respectively, to a height no greater than 5 millimeters. The present invention also pertains to a micromechanical barb for linking with an object. The micrormechanical barb comprises a base. The micromechanical barb is also comprised of a support which extends from the base. The micromechanical barb additionally is comprised of a head which is disposed upon the support and which mates with the object such that a locking connection is found therebetween. The length of the support and the head is less than 5 millimeters.
