Implantable prosthetic valve with collapsible and expandable features
A newly granted patent (Publication Number: US11925550B2) discloses an implantable prosthetic valve that is designed to be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve comprises an annular frame with angled strut members, leaflets secured within the frame, a skirt member wrapped around the edge portion of a leaflet, and a cord member threaded through extension portions of the skirt member to secure it to the frame. The design allows for flexibility in configurations, such as bicuspid or tricuspid arrangements, and includes features like tubular extension portions and an outer skirt secured with the cord member.
Furthermore, the patent details variations in the prosthetic valve design, including different arrangements of leaflets and skirt members, the use of sutures for securing the skirt member to the leaflet edge, and the alignment of extension portions along the frame. The cord member, which can also be a suture, plays a crucial role in maintaining the structure of the prosthetic valve in both collapsed and expanded states. The innovative features of the prosthetic valve aim to improve functionality and durability, offering a promising solution for implantable medical devices in the field of prosthetic valves.
