Embodiment Construction

[0216] Certain terms used in the following description are for convenience only and not for limitation. The words "right", "left", "lower" and "upper" indicate directions in the drawings to which reference is made. The words "inner" or "distal" and "outer" or "proximal" refer to directions toward and away from, respectively, the geometric center of the patient's body or the suture passer instrument and its associated components. The words "front", "rear", "above", "below" and related words and / or phrases refer to preferred positions and orientations of the human body with reference to them and are not limiting. Terminology includes the above words, derivatives and words of similar import.

[0217] refer to Figures 1A-1C , a bidirectional suture extends through the instrument 10 in the longitudinal direction L and includes a proximal end P and a distal end D. As shown, the instrument 10 includes a handle 14 , an elongated body 18 connected to the handle 14 , and a frame arm...

Abstract

The present application discloses a bidirectional suture passing instrument arranged to vertically approach soft tissue, enabling safer and more efficient surgical repair, using minimally invasive techniques, and can be used, for example, in annulus repair, meniscus repair, shoulder arthroscopy Examination, hernia repair, laparoscopic repair and wound closure.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from US Provisional Patent Application 61 / 147251, filed January 26, 2009, the entire contents of which are incorporated herein by reference. Background technique [0003] Sutures passed for repair of soft tissue defects. Sutures are typically attached to free needles or unidirectional suture passing instruments (instruments that allow the suture to pass through tissue in only one direction) for use in surgery. [0004] Bi-directional suture-passing instruments (instruments that enable sutures to pass through tissue in both a forward direction (away from the user) and a posterior direction (toward the user)) can have several advantages over unidirectional suture-passing instruments. Many unidirectional suture passers require an additional step to manually retrieve and pass the suture in the opposite direction, increasing the complexity of the surgical technique and process time. Some uni...
