Patent number: 12629251Abstract: 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. A dual-wireform support frame including an upper and a lower wireform permits expansion of the valve by one or two valve sizes, for example, with a 2-mm gap between each valve size. The lower wireform has a relatively shallow undulation so that it may stretch apart by a small amount and then prevent further expansion of the valve.Type: GrantFiled: September 28, 2021Date of Patent: May 19, 2026Assignee: Edwards Lifesciences CorporationInventors: Derrick Johnson, Michael C. Murad, Steven M. Ford, Rodolfo Rodriguez

Publication number: 20260013986Abstract: Valve holders and introducers for delivering a prosthetic heart valve to an implant site are in various embodiments configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a removable activator dial and a removable handle that prevent implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate passing of a prosthetic valve between adjacent ribs of a patient. Valve holders and introducers according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.Type: ApplicationFiled: September 22, 2025Publication date: January 15, 2026Inventors: Brian S. Conklin, Derrick Johnson

Publication number: 20250064586Abstract: A prosthetic heart valve for implant in a human. The valve includes a wireform with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. Each leaflet may drape over the top of the wireform in the cusp area, but have tabs that each extend underneath the wireform at the commissure posts to be secured along with a tab of an adjacent leaflet. The prosthetic heart valve may also be a dual-wire wireform, with the leaflets sandwiched therebetween. One wireform may be larger than the other, with the leaflets extending over the smaller wireform. The smaller wireform may have commissures that bend radially outward from the larger wireform to provide structure to which the leaflet tabs attach.Type: ApplicationFiled: November 14, 2024Publication date: February 27, 2025Inventors: Derrick Johnson, Van Huynh, Qinggang Zeng
