US 2022/0054261 A1 · MINIMAL FRAME PROSTHETIC CARDIAC VALVE DELIVERY DEVICES, SYSTEMS, AND METHODS

Abstract

Disclosed herein are prosthetic valve devices, systems, and methods of installation of prosthetic valve devices and systems in a target region of a subject. Prosthetic valve devices disclosed herein comprise a frame structure having expanded and unexpanded configurations aiding in minimally-invasive delivery of the devices to the target region. The prosthetic valve devices include frame structures designed to minimize the amount of material used to form the devices without sacrificing structural strength. The prosthetic valve devices also include frame structures of minimal longitudinal length, allowing easier and more precise delivery and deployment of the devices.

Dependent claims

A device for treating a diseased native valve in a patient, the device comprising:

a frame structure having an unexpanded configuration and an expanded configuration, the frame structure in the expanded configuration comprising a first end portion, a central annular portion, and a second end portion;
and
a valve segment coupled to the central annular portion and at least partially longitudinally aligned with the first end portion when the frame structure is in the expanded configuration, the valve segment comprising a biocompatible one-way valve;
wherein an inflow edge of the valve segment is unsupported by the first end portion of the frame structure and spaced radially inwards from the first end portion when the frame structure is in the expanded configuration.
