Benefits of technology

[0010] The present invention pertains to methods, and related tools for performing the method, of delivering a stent or other like-device to the heart to connect the left ventricle to the coronary artery to thereby supply blood directly from the ventricle to the coronary artery. In a preferred embodiment, a method may be used to bypass a total or partial occlusion of a coronary artery. The inventive method is relatively quicker and less invasive

Problems solved by technology

Because the coronary artery supplies blood to the various blood vessels within the muscle forming the heart wall, limiting or blocking of the blood flow through the coronary artery can result in damage to the heart muscle, such as, for example, necrosis.
Necrotic tissue can lead to reduced cardiac function by diminishing the pumping capacity of the heart.

Embodiment Construction

[0038] An aspect of the present invention includes a novel method of placing a stent within the heart wall between the left ventricle and the coronary artery to provide blood flow directly therebetween. The novel method generally includes the steps of establishing a position of a passageway between the left ventricle and the coronary artery, creating the passageway, and placing a stent in the passageway. Each of these general steps will be described in greater detail below.

[0039] Although the methods according to the invention will be described with reference to establishing direct blood flow between the left ventricle and left anterior descending coronary artery, connections between other heart structures and vessels to establish flow therebetween also are within the scope of the invention. In addition, the inventive methods may be used in other settings, aside from the heart, that require creating a passage or conduit and delivering a device into the created passage to establish ...

Abstract

Embodiments of the invention include a device for placing a stent in a heart wall. The device may include a delivery tool configured to deliver the stent to a location within the heart wall, and a stop mechanism disposed on the delivery tool such that the stop mechanism is proximate at least one end of the stent during delivery of the stent. The stop mechanism may be configured to engage a surface to determine the placement location of the stent within the heart wall.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefits of U.S. Provisional Patent Application Ser. No. 60 / 201,732, filed May 4, 2000.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to methods and related devices for forming a passageway in a heart wall and delivering a stent therein to supply oxygenated blood flow to vascular structure from a chamber of the heart. For example, the methods and related devices preferably place a stent in the left ventricular heart wall in order to establish a supply of blood from the left ventricle to the coronary artery at a point distal a partial or total occlusion of the artery. [0004] 2. Background of the Related Art [0005] A prevalent form of heart failure involves the build-up of plaque on walls of various vascular structure, such as, for example, the coronary artery. The plaque that builds up on the walls can form either a partial or total occlusion in the artery. Su...
