Embodiment Construction

[0013] Hereinafter, a knotless wound closure device for forming continuous stitches and having reversed anchor points for proper functioning is described. The knotless wound closure device of the present disclosure eliminates the failure rate caused at or near the anchor point, which would result in loss of tissue access support and leakage of blood and fluid. The unique geometry and use of knotless wound closure devices also reduces or eliminates patient discomfort caused by sharp protrusions that barbed suture devices can feel.

[0014] Thus, knot-free wound closure devices were fabricated with specific geometries, i.e., with a number of surface features interfaced with a unique matching through-hole passing through the elongate flexible body of the wound closure device. The longitudinal axis is long and prepared, which acts as a one-way locking mechanism.

[0015] Referring now to the drawings in detail, in which like reference numerals are applied to like features in the ...

Abstract

A knotless wound closure device includes an elongated flexible body having a proximal end and a distal end, the elongated flexible body having a plurality of apertures therethrough along its length, and defining a longitudinal axis with a plurality of Shaft extended surface features. The proximal end is shaped and sized to pass through body tissue and then selectively passed through at least one of a plurality of through holes so that at least one of the surface features also passes through the through hole to form a locking closure loops to ensure body tissue is securely held within.

Description

technical field [0001] The present disclosure generally relates to wound closure devices with uninterrupted or continuous sutures. Background technique [0002] Over the years, surgeons have used a variety of wound closure devices and methods to close tissue wounds. Suturing is a surgical technique that involves joining tissue by sewing it together with a thread of suitable suture material. [0003] Typically, suturing is performed by passing a needle attached to a suture through the tissue on either side of the wound, pulling the ends of the suture to bring the sides of the wound together, and tying the suture in a knot. The tied knot maintains tension on the sutures to keep the sides of the wound close and the tissue to heal. A knot that is improperly tied may slip and unravel at a tension much less than that required to break the suture. While the suture is in the body, another surgical procedure may be required to compensate for the unsuccessful suture. [0004] Vari...
