Mesh suture with anti-roping characteristics

Abstract

The invention provides a medical device that includes a surgical needle attached to a mesh suture having anti-roping elements. The suture is constructed of a macroporous mesh wall that facilitates and allows tissue integration subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility. Advantageously, the anti-roping elements serve to maintain the desired construct of the mesh wall when undergoing axial tensile loads by resisting elongation and loss of outer mesh wall macroporosity, while still permitting a flattening of the suture with lateral loading.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Provisional Application No. 62 / 134,099, filed March 17, 2015, which is expressly incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to sutures with structural features that enhance closure, prevent suture pull through, and / or resist infection, and methods of use thereof. Background technique [0004] One of the cornerstones of surgery is the use of sutures to reappropriate the soft tissue, ie to hold the tissue in the desired configuration until it can heal. In principle, suturing constitutes the introduction of highly stretched foreign constructs (looped sutures) into separate pieces of tissue in order to hold these pieces in close proximity until scarring can occur, establishing continuity and strength between the tissues. The sutures initially provide the full strength of the repair, but as the tissue heals, they b...
