Claims (8)

1. 1. A device for attaching an implant to a tissue comprising a first strand having two opposing ends forming two adjustable and lockable loops and at least one second strand being slidably connected to a first loop of said two adjustable and lockable loops.
2. 2. The device of claim 1, further comprising a needle attached to said at least one second strand.
3. 3. The device of claim 2, wherein said needle is also attached to one of said two opposing ends of said first strand.
4. 4. The device of claim 1, wherein said two adjustable and lockable loops are formed by threading each of said two opposing ends through a splice section formed in said first strand.
5. 5. The device of claim 1, wherein said at least one second strand is slidably connected to said first loop of said two adjustable and lockable loops through a braided cuff.
6. 6. The device of claim 1, further comprising an additional second strand being slidably connected to a second loop of said two adjustable and lockable loops.
7. 7. A method of attaching an implant to a tissue comprising: (a) passing through tissue and the implant a needle attached to: (i) a first strand having two opposing ends forming two adjustable and lockable loops; and (ii) at least one second strand being slidably connected through a braided cuff to a first loop of said two adjustable and lockable loops; (b) pulling each of said two opposing ends to thereby tighten said two adjustable and lockable loops and force said braided cuff against a surface of the implant and lock the implant against the tissue.
8. 8. The method of claim 7, wherein the implant is an annular ring and said tissue is a valve annulus.

Description

DEVICE AND METHOD FOR SECURING AN IMPLANT TO TISSUE RELATED APPLICATION/S This application claims the benefit of priority of U.S. Provisional Patent Application No. 63/511,694, filed on July 3, 2023, the contents of which are incorporated herein by reference in their entirety. BACKGROUND The present invention relates to a device and to a method of using same for securing an implant to a tissue. Embodiments of the present invention relate to securement of a prosthetic device to a valve annulus using a knotless suture approach. Surgical sutures are used in a variety of surgical repair procedures from simple wound closure to repair of muscles, connective tissue and even hard tissue. Sutures are typically secured using knots or suture-locking devices. Knot tying is labor-intensive and may significantly increase the overall time of a surgical procedure. In addition, in some surgical procedures the existence of the knot itself (or a knot-locking device) may be disadvantageous. For example, in mitral valve replacement procedures, a sewing ring surrounds the new valve and is used to sew the valve in place within the valve annulus. A typical procedure can utilize numerous knots or suture-locking devices that can adversely affect the profile of the ring. Self-locking sutures (e.g., barbed sutures) overcome the above limitations, however, such sutures can be prone to failure as the required holding strength needed for a particular procedure increases. Thus, it would be desirable to provide a suture having an increased holding strength and/or reduces or eliminates the need for knot tying. SUMMARY According to one aspect of the present invention there is provided a device for attaching an implant to a tissue comprising a first strand having two opposing ends forming two adjustable and lockable loops and at least one second strand being slidably connected to a first loop of the two adjustable and lockable loops. According to embodiments of the present invention the device further comprises a needle attached to the at least one second strand. According to embodiments of the present invention the needle is also attached to one of the two opposing ends of the first strand. According to embodiments of the present invention the two adjustable and lockable loops are formed by threading each of the two opposing ends through a splice section formed in the first strand. According to embodiments of the present invention at least one second strand is slidably connected to the first loop of the two adjustable and lockable loops through a braided cuff. According to embodiments of the present invention the device further comprises an additional second strand being slidably connected to a second loop of the two adjustable and lockable loops. According to another aspect of the present invention there is provided method of attaching an implant to a tissue comprising passing through tissue and the implant a needle attached to a first and second strand having two opposing ends forming two adjustable and lockable loops; and at least one second strand being slidably connected through a braided cuff to a first loop of the two adjustable and lockable loops; and pulling each of the two opposing ends to thereby tighten the two adjustable and lockable loops and force the braided cuff against a surface of the implant and lock the implant against the tissue. According to embodiments of the present invention the implant is an annular ring and the tissue is a valve annulus. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, suitable methods and materials are described below. In case of conflict, the patent specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting.
