Embodiment Construction

[0031] As mentioned herein, the prosthetic heart valves used in the various heart valve delivery devices and methods of the present invention can include a variety of different configurations, such as prosthetic heart valves with tissue leaflets, or with polymeric, metal, or tissue designs (tissue-engineered) leaflet artificial heart valve, and can be specially constructed to replace any heart valve. That is, although most of what has been described here refers to the replacement of aortic valves, the prosthetic heart valves of the present invention can also generally be used to replace native mitral, pulmonary, or tricuspid valves, to serve as venous valves, or to replace Failed bioprostheses in areas such as the aortic valve or mitral valve.

[0032] In general, the stents described herein include a support structure comprising a plurality of support strips or wire segments arranged relative to each other to provide the desired compressibility, strength and leaflet attachmen...

Abstract

A surgical sutureless valve (40) that is attached to a stent frame (50) for delivery to a location in a patient using percutaneous implantation devices and methods.

Description

technical field [0001] The present invention relates to prosthetic heart valves. More particularly, the present invention relates to surgical sutureless valves and methods for percutaneous implantation of such prosthetic heart valves in combination with stent structures. Background technique [0002] A patient's or otherwise defective heart valve can be repaired or replaced using a variety of different types of heart valve surgery. Typical heart valve surgery involves open heart surgery, which is performed under general anesthesia, during which the heart is stopped and blood flow is controlled by a heart-lung bypass machine. This type of valve surgery is invasive and exposes the patient to a number of potentially serious risks, such as infection, stroke, renal necrosis, and adverse effects associated with the use of a heart-lung machine. [0003] In recent years, minimally invasive percutaneous heart valve replacement has received increasing attention. This surgical techn...
