Knotless locking tissue fastening system and method

摘要

Systems and methods for fastening tissue include a tissue fastening device comprising an elongate element and a delivery device including a cone, suture, and needle arranged at a delivery end of the elongate element. At least one of the tissue locking features and a tissue lock device are arranged at an end of the elongate element opposite the delivery end. The system includes a locking feature near the delivery end, and a lock device having a mating feature that corresponds to the locking feature. When the delivery device is passed through the lock device, the mating feature engages the locking feature and locks the lock device in an axial direction along the elongate element.

1. A system for fastening tissue, comprising:
a tissue fastening device comprising an elongate element; a delivery device comprising a cone, suture, and needle arranged at a delivery end of the elongate element, wherein the suture is connected between the cone and the needle, and the suture is a different element than the elongate element; a tissue lock device arranged at an end of the elongate element opposite the delivery end; a locking feature near the delivery end; and a lock device having a mating feature that corresponds to the locking feature; wherein when the delivery device is passed through the lock device, the mating feature engages the locking feature and locks the lock device in an axial direction along the elongate element, the tissue lock device comprises a groove, the elongate element comprises a head element that fits within the groove such that a top surface of the head element is substantially flush with a top surface of the tissue lock device, and the head element extends outward relative to the elongate element in a radial direction and has a larger dimension than the elongate element in the radial direction.
