Patent number: 10456246Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible to a limited degree for delivery and expandable post-implant to facilitate a valve-in-valve (ViV) procedure. The hybrid heart valves eliminate earlier structural bands, which both reduces manufacturing time and facilitates a ViV procedure.Type: GrantFiled: June 30, 2016Date of Patent: October 29, 2019Assignee: Edwards Lifesciences CorporationInventors: Brian S. Conklin, Qinggang Zeng, Myron Howanec, Jr., Grace Myong Kim

Publication number: 20190167422Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.Type: ApplicationFiled: February 8, 2019Publication date: June 6, 2019Inventors: Jessica Guttenberg, Da-Yu Chang, Derrick Johnson, Brian S. Conklin, Qinggang Zeng, Myron Howanec, JR., Grace Myong Kim

Patent number: 7008591Abstract: The present invention provides methods for preparing tissue for incorporation into xenografts and bioprosthetic devices. The methods of the invention make use of supercritical fluids to remove infectious materials and chemical agents from tissues, as well as to permeate a tissue with a chemical agent (e.g. tanning, cross-linking, and bioactive agents).Type: GrantFiled: October 17, 2001Date of Patent: March 7, 2006Assignee: Edwards LIfesciences CorporationInventors: Ralph Kafesjian, Myron Howanec, Jr.

Patent number: 6964682Abstract: An improved holder, system and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and may also constrict the commissure posts of the valve. The holder may include two relatively movable plates, one of which attaches to the valve sewing on the inflow end of the valve ring and the other which attaches via sutures or similar expedient to the valve commissures on the outflow end. Separation of the plates places the sutures in tension and constricts the commissures. The sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover. The flexible lengths of material extend directly between commissures of the valve, or may extending radially inward from each commissure to a central upstanding member.Type: GrantFiled: December 21, 2000Date of Patent: November 15, 2005Assignee: Edwards Lifesciences CorporationInventors: Diana Nguyen-Thien-Nhon, Myron Howanec, Jr., Ralph Kafesjian, Delos M.

Patent number: 6503274Abstract: A design and method of implantation is disclosed for a flexible annuloplasty system for repairing a valve in a patient's heart. The annuloplasty system includes an elongate, flexible band with a needle attached to one end of the band and a fit adjuster attached to the other end of the band. The band is made of silicone and includes a plurality of fibers that are configured to prevent axial elongation of the band. In addition, the plurality of fibers ensure that a suture will catch on the fibers and prevent the suture from tearing out of the band.Type: GrantFiled: November 8, 2000Date of Patent: January 7, 2003Assignee: Edwards Lifesciences CorporationInventors: Myron Howanec, Jr., Michael John Scott, Brian Eugene Brutcher, Jerry L.
