Problems solved by technology

Heart valves, such as the mitral, tricuspid, aortic, and pulmonary valves, are sometimes damaged by disease or by aging, resulting in problems with the proper functioning of the valve.
Heart valve problems generally take one of two forms: stenosis in which a valve does not open completely or the opening is too small, resulting in restricted blood flow; or insufficiency in which blood leaks backward across a valve when it should be closed.
Traditional open surgery inflicts significant patient trauma and discomfort, requires extensive recuperation times, and may result in life-threatening complications.
While considerable effort has been devoted to such techniques, widespread acceptance has been limited by the clinician's ability to access only certain regions of the heart using laparoscopic instruments.
While some problems of traditional open-heart surgery

Embodiment Construction

[0027]Specific embodiments of the present invention are now described with reference to the figures, wherein like reference numbers indicate identical or functionally similar elements. The terms “distal” and “proximal” when used in the following description to refer to a catheter or delivery system are with respect to a position or direction relative to the treating clinician. Thus, “distal” and “distally” refer to positions distant from or in a direction away from the clinician and “proximal” and “proximally” refer to positions near or in a direction toward the clinician. When the terms “distal” and “proximal” are used in the following description to refer to a device to be implanted into a vessel, such as an anchor stent assembly or valve component, they are used with reference to the direction of blood flow from the heart. Thus, “distal” and “distally” refer to positions in a downstream direction with respect to the direction of blood flow and “proximal” and “proximally” refer to...

Abstract

An anchor stent assembly to be used with a valve component includes a generally tubular frame having a first end and a second end, the frame defining a central passage and a central axis. A secondary passage is defined between n inner surface of the frame and an outer surface of an inner rib disposed closer to the central axis than the frame. An extension tube is disposed through the secondary passage. The extension tube includes an extension tube lumen having a first opening at a first end of the extension tube and a second opening at a second end of the extension tube.

Description

FIELD OF THE INVENTION[0001]Embodiments hereof relate to heart valve prostheses and methods for intraluminally deploying heart valve prostheses, and in particular, to heart valve prostheses including coronary access and methods of intraluminally delivering and deploying such heart valve prostheses.BACKGROUND OF THE INVENTION[0002]Heart valves, such as the mitral, tricuspid, aortic, and pulmonary valves, are sometimes damaged by disease or by aging, resulting in problems with the proper functioning of the valve. Heart valve problems generally take one of two forms: stenosis in which a valve does not open completely or the opening is too small, resulting in restricted blood flow; or insufficiency in which blood leaks backward across a valve when it should be closed.[0003]Heart valve replacement has become a routine surgical procedure for patients suffering from valve regurgitation or stenotic calcification of the leaflets. Conventionally, the vast majority of valve replacements entail...
