Tissue fixation system and method

摘要

A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. A medical device is used to secure the fastener to the elongate fastening member. The medical device includes a tensioning mechanism for tensioning the elongate fastening member. As crimping mechanism is used to secure the fastener to the elongated member, where a cutting mechanism cut the excess portion of the elongated member.

主权项

1. A medical device for securing a fastener to an elongate member, comprising:
a handle; a tubular member coupled to the handle, the tubular member including first and second ends and defining a longitudinal passage along a central longitudinal axis; a tensioning mechanism disposed on the handle for tensioning the elongate member to a predetermined tension by actuating the tensioning mechanism, the tensioning mechanism including a torque controller that enables the tensioning mechanism to be further actuated after the predetermined tension is applied to elongate member such that the predetermined tension on the elongate member is maintained and prevents a tension greater than the predetermined tension to be applied to the elongate member; and a crimp mechanism positionable in at least a portion of the first end on the tubular member for crimping the fastener about the elongate member.
