Support device for valve prostheses and corresponding kit

摘要

A support device for implanting stentless valve prostheses, such as biological heart valves, includes a hub and a plurality of support portions for supporting the stentless valve prosthesis. The hub defines a manipulation axis for the device and is flexibly connected to the support portions to allow displacing the manipulation axis for the device between the support portions.

主权项

1. A delivery system for implanting a stentless valve prosthesis, the system comprising:
the stentless valve prosthesis comprising a plurality of commissure portions, and a plurality of valve leaflets, wherein each valve leaflet extends between two adjacent commissure portions, and; a support device comprising:
a hub defining a manipulation axis for the device, anda plurality of support portions for supporting the stentless valve prosthesis that extend radially from the hub, exhibit a shape with a proximal portion connected to the hub and a distal portion that extends back proximally toward the hub, and are configured to extend along and support the commissure portions of the stentless valve prosthesis, wherein the hub is connected to the support portions via an elastically flexible connection to elastically bias the hub centrally of the support portions, and at least a portion of the distal portion of each support portion extends proximal to the elastically flexible connection.
