摘要:
A barbed suture includes a flexible thread having a leading end and a trailing end, and a plurality of barbs projecting from the flexible thread. The flexible thread has a plurality of web-like openings formed therein, whereby each of the openings is disposed adjacent one of the barbs. The openings enhance the flexibility of the barbs and provide space for the barbs to collapse inwardly as the leading end of the flexible thread is pulled through a medium such as tissue. When the barbs are collapsed, the diameter of the barbed sections is preferably no greater than the diameter of the non-barbed sections. In one embodiment, a support element interconnects at least one of the barbs and the flexible thread for reinforcing the at least one barb and resisting flexure of the at least one barb toward the leading end of the flexible thread.
