Surgical suture system

摘要

A surgical suture system, suture, and tissue engaging member for tissue repair and reattachment of torn tissue to a tissue substrate, medical prosthesis or medical implant. The system includes the elongated flexible suture member having a plurality of longitudinally spaced protuberances along a length thereof and one or a plurality of the tissue engaging members each of which include two closely spaced apart locking apertures sized and configured to receive one of the suture members passed therethrough or a unique single locking aperture to allow longitudinal tensioning and/or restraining movement of the suture member in only one direction through the locking apertures for suture member tightening.

1. A surgical tissue engaging member for tissue repair and reattachment of torn tissue to a tissue substrate, medical prosthesis, or medical implant in conjunction with an elongated slender flexible suture member having a plurality of longitudinally spaced protuberances along a length thereof, said tissue engaging member comprising:
an expandable suture tissue restraint comprising a plurality of circumferentially spaced solid segments; a series of expandable aperture segments each having a first and a second end secured to adjacent solid segments with said solid segments and expandable aperture segments defining an expandable locking aperture; said solid segments and said expandable aperture segments having inward tapered surfaces defining an inward tapered wall at a circumference of said expandable locking aperture; and said expandable suture tissue restraint being circumferentially expandable for enabling the plurality of longitudinally spaced protuberances of the flexible suture member to pass along said inward tapered surfaces of said expandable locking aperture in only one direction through said expandable locking aperture.
