Abstract
Suture passers and methods of suturing tissue to prevent tissue bridging, without requiring a cannula. Tissue bridging involves the capture of non-target tissue within a loop of suture formed around and/or through a target tissue. The devices and methods described herein may include the use of a threading aperture at or near the distal end of the suture passer to guide the device in passing a suture through the tissue along the same pathway that another leg or legs of the loop took to access the target tissue, thereby preventing the inadvertent capture of non-target tissue leading to tissue bridging. In particular, described herein are suture passers and methods of arthroscopically suturing the meniscus of the knee while preventing tissue bridging.
