Angled suture passer and method of use thereof

Abstract

A suture passer which is sized and shaped to be inserted through the femoral notch during a meniscal repair. The suture passer includes upper and lower jaws that may be straight or that may have an angled offset in relation to the common axis of the suture passer in order to gain an indirect access to meniscal tissue in a constricted space. The jaws of the suture passer may be angled, either to the left or to the right, up to 45 degrees from the central axis of the shaft. The suture passer is also able to grasp meniscal tissue prior to suture passing. A nitinol needle housed within one of thejaws can then be deployed to pass a preloaded suture through the tissue to be captured on the opposite side of the tissue.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 478,204, filed March 29, 2017, entitled "ANGLED SUTURE PASSER AND METHOD OF USE THEREOF," The entire disclosure content thereof is incorporated herein by reference. technical field [0003] The present disclosure relates to surgical instruments for manipulating sutures. In particular, the present disclosure relates to an instrument for threading sutures through tissue. Background technique [0004] In many surgical procedures such as anterior cruciate ligament (ACL) surgery for knee or shoulder instability repair, sutures are used to close wounds and may be used to repair damage to the ligament and soft tissues. As part of a repair, sutures may be threaded through the tissue to stitch or hold the tissue together, or to capture and anchor the tissue to a surgical implant, such as a suture anchor. Known instruments for suture passing generally in...

Problems solved by technology

Therefore, the optimal suture passer for direct access requires a width of 2mm or less, and thus may not be strong enough to perform suture passing
