AI Technical Summary

Problems solved by technology

With conventional delivery devices, tension exerted on parts of the device can cause the radiopaque markers to displace relative to the prosthetic valve, which can cause the prosthetic valve to deploy in an incorrect position

Embodiment Construction

[0028] Described herein are systems and methods for delivering a prosthetic device, such as a prosthetic heart valve, through the body and into the heart for implantation therein.

[0029] The prosthetic valves disclosed herein are radially compressible and expandable between a radially compressed configuration and a radially expanded configuration. Thus, during delivery, the prosthetic valve can be creased in a radially compressed configuration on the implant delivery device, and then expanded to a radially expanded configuration after the prosthetic valve reaches the implantation site.

[0030] figure 1 An exemplary prosthetic valve 10 is shown, according to one embodiment. In a particular embodiment, the prosthetic valve 10 may be implanted within the native aortic annulus, but it may also be implanted at other locations in the heart (including implanted in the native mitral valve, native pulmonary valve, and within the native tricuspid valve). Prosthetic heart valve 10 ...

Abstract

A delivery apparatus can include a handle, a first shaft extending from the handle and having a proximal end portion coupled to the handle and a distal end portion and a second shaft extending coaxially over the first shaft and having a proximal end portion coupled to the handle and a distal end portion. The delivery apparatus can further include a shoulder coupled to the distal end portion of the second shaft and having a flared end portion configured to abut a prosthetic valve positioned around the first shaft in a radially compressed state, an extension portion extending from the shoulder, and at least one radiopaque marker disposed on the extension portion at a location within the prosthetic valve when the prosthetic valve is in a radially compressed configuration on the first shaft.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application 62 / 778,159, filed December 11, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to embodiments of a delivery system for implanting a prosthetic heart valve. Background technique [0004] Prosthetic heart valves have been used to treat heart valve disorders for many years. Native heart valves such as the aortic, pulmonary, and mitral valves play a vital role in ensuring an adequate blood supply and positive flow through the cardiovascular system. Congenital, inflammatory or infectious conditions can make these heart valves less effective. Such damage to the valves can lead to severe cardiovascular damage or death. For many years, the definitive treatment for such conditions has been surgical repair or replacement of the valve during open heart surgery, but such surgery is prone t...
