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. Southard, Jack Bokros, Elva Correa, Jeffery Poehlmann

Publication number: 20070219629Abstract: A heart valve holder-inserter (21, 121) is designed to facilitate easy implantation of a mechanical heart valve pros-thesis (23, 123). This holder-inserter, at its distal end, incorporates a pair of diametrically opposed guide members (47, 49, 81, 147, 149) which extend well beyond the leading edge of the prosthesis and which have exterior surfaces (53, 83, 153) of substantial dimension that are smoothly curved and proportioned so as to slowly spread the tissue annulus in order to facilitate easy entrance thereinto of the leading edge portion of the mechanical valve body.Type: ApplicationFiled: January 23, 2006Publication date: September 20, 2007Applicant: VALVE SPECIAL PURPOSE CO., LLCInventors: Jack Bokros, Jonathan Stupka, C.

Publication number: 20050246032Abstract: A bone implant (71) comprises a body formed of an articulated open cell structure of a lightweight material, the surfaces of which structure are covered with a thin metal layer. A layer of biocompatible pyrocarbon coating is applied to the metal-coated structure so as to cover the entire structure and provide a dense, nonporous, biocompatible layer. Pyrocarbon is then selectively removed from portions (73) of the surface of the body to expose sections of the original surface which lead to regions of interconnected channels into which bone and tissue ingrowth are promoted while end regions (75) and (77) remain totally covered with such pyrocarbon.Type: ApplicationFiled: December 20, 2004Publication date: November 3, 2005Applicant: Medical Carbon Research InstituteInventors: Jack Bokros, Robert More, James Accuntius

Patent number: 4689046Abstract: A heart valve prosthesis with an annular body portion and at least one valve leaflet moveable between open, closed, and intermediate positions. The body includes leaflet ear support formations, each with a contoured recess having spaced apart, tapered arcuate guide wall surfaces and spaced apart convex ear support surfaces. Each valve leaflet includes mounting ears with upper and lower support surfaces of generally trapezoidal outline, a generally flat end face portion, and two spaced apart guide surface portions tapered so as to lie in closely spaced apart relation to the tapered guide walls in the recess.Type: GrantFiled: March 11, 1985Date of Patent: August 25, 1987Assignee: CarboMedics, Inc.Inventor: Jack Bokros
