Embodiment Construction

[0048] In at least one aspect, the present disclosure is directed to a catheter system for sequentially deploying a stent-graft comprising a first retaining sleeve, a second retaining sleeve, a catheter shaft, and a stent-graft holder, wherein the first sleeve Axially movable relative to the catheter shaft, the second sleeve is axially fixed to the catheter shaft, and the stent holder is axially movable relative to the catheter shaft.

[0049] Various embodiments of the present disclosure may address one or more of the goals discussed above in an advantageous and unexpected manner. In particular, delivery, positioning, and / or repositioning of a heart valve prosthesis may be facilitated in some aspects.

[0050] In at least one aspect, the present disclosure relates to a method of sequentially deploying a stent-graft, wherein movement of the first sheath (11) of the catheter is followed by movement of the stent-graft holder (15), resulting in grafting Release and directional d...

Abstract

The present disclosure relates to a delivery catheter and gradual release of a stent membrane from the catheter into a patient's vasculature, and a loading device for a transcatheter heart valve (THV) prosthesis.

Description

[0001] manual [0002] The present disclosure relates to delivery systems, catheter systems and methods for minimally invasively applying prostheses to individuals in need of such prostheses and methods and devices for loading prostheses onto catheter systems and / or delivery systems. [0003] This application is related to U.S. Provisional Application No. 62 / 136,092, filed March 20, 2015, and U.S. Provisional Application No. 62 / 336,153, filed May 13, 2016, the entire disclosure of which is incorporated by reference way incorporated into this article. Background technique [0004] The present disclosure relates to the field of medical devices and, in particular, to prostheses that are implanted in individuals in need thereof to re-establish proper bodily function by minimally invasive methods and means adapted thereto. [0005] Examples of prostheses placed by minimally invasive methods are stenting membranes and heart valves such as the aortic valve and mitral valve, for exam...
