Publication number: 20230293298Abstract: The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation enhancement element for implantation across the valve; a system including the coaptation enhancement element and anchors for implantation; a system including the coaptation enhancement element, catheter and driver; and a method for transcatheter implantation of a coaptation element across a heart valve.Type: ApplicationFiled: April 5, 2023Publication date: September 21, 2023Inventors: Alexander Khairkhahan, Michael D.

Publication number: 20230293299Abstract: Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle.Type: ApplicationFiled: April 5, 2023Publication date: September 21, 2023Inventors: Alexander Khairkhahan, Michael D.

Publication number: 20220257238Abstract: A suture clip includes a disc body having at least two adjacent portions joined by a hinge at one end and a latch at another end. Suture engagement surfaces are formed on a first and second portion of the disc body so that the first and second suture engagement surfaces can close sufficiently tightly to immobilize a pair of suture lengths therebetween when the two portions are closed and held together by the latch. A suture clip applier holds a plurality of such suture clips typically in a magazine, an open configuration where the suture engagement surfaces are held apart. Single suture clips are advanced by an advancement mechanism over a pair of suture ends having a midsection in tissue. A closing mechanism closes and latches the first and second portions of the disc body together to capture the pair of suture ends therebetween.Type: ApplicationFiled: May 9, 2022Publication date: August 18, 2022Applicant: Vquad Medical LLCInventors: Sebastian Khairkhahan, Alexander Khairkhahan
