Patent number: 10695169Abstract: An embodiment of the invention includes a sewing cuff for aortic heart valves that better approximates native anatomy by better mating with the crown-like anatomical annulus. Limiting distortion of the crown-like annulus provides better blood flow and overall valve function and provides a physician greater ease of implantation since native anatomy is not flattened. Thus, the surgeon may attach sutures to the fibrous tissue of the crown-like anatomical annulus without distorting the shape of the native anatomy. An embodiment includes a scalloped sewing cuff assembly (with semilunar arches) that tracks the crown-like annulus. Another embodiment provides a sewing cuff positioned over the majority of the valve's length, thus allowing the surgeon greater flexibility as to where he or she can attach sutures to the surgical annulus. Conventional valves, which are primarily “low-profile” devices, do not offer such ability. Other embodiments are described herein.Type: GrantFiled: September 20, 2017Date of Patent: June 30, 2020Assignee: On-X Life Technologies, Inc.Inventors: Francisco Javier Ruyra-Baliarda, Josep Gatell Ferre, Fletcher D.

Patent number: 10213303Abstract: An embodiment includes an apparatus comprising: a hollow needle with a narrowed inner diameter in a distal third of the needle; and a flexible chord coupled to proximal and distal conduits; wherein the distal conduit is in the needle and distal to the narrowed inner diameter and the proximal conduit is in the needle and proximal to the narrowed inner diameter; wherein: (a)(i) long axes of the proximal and distal conduits are substantially parallel to a long axis of the needle when the proximal and distal conduits are in the needle, and (a)(ii) the proximal and distal conduits are configured to rotate when deployed from the needle such that their long axes are not parallel to a long axis of the chord when the chord is fully extended. Other embodiments are described herein.Type: GrantFiled: October 26, 2016Date of Patent: February 26, 2019Assignee: On-X Life Technologies, Inc.Inventors: Ryan Medema, Mark Seeley
