Percardia, Inc. - Merrimack NH

International Classification:

A61F 206

US Classification:

623 111, 623 1211, 606108, 606194, 128898

Abstract:

Described herein are various methods and apparatuses for delivering stents or conduits and other devices into the myocardium of a patient. One preferred stent delivery system provides access to the insertion site in the myocardium by advancing a delivery catheter through a blockage in a coronary artery, or around the blockage through a coronary vein or through a channel or tunnel formed around the blockage. In one embodiment, once the distal end of the delivery catheter is adjacent the myocardium, an angled bend is created in the catheter by actuating expandable steering guides mounted to the catheter which cooperate with the walls of the blood vessel to cause the catheter to turn. Then, a guidewire is advanced through the delivery catheter and into the myocardium. In another embodiment, a tip-deflecting pull wire extends from the distal end of the delivery catheter which may be actuated to turn towards and then inserted into the myocardium. In another embodiment, an exit port facing the insertion site is provided within the catheter or a balloon mounted on the catheter so that a guidewire may be directed through a lumen and out the exit port into the:.

International Classification:

A61F 206

US Classification:

623 13, 606153

Abstract:

Disclosed is a conduit that provides a bypass around a stenosis or occlusion in a coronary artery. The conduit is adapted to be positioned in the myocardium to provide a passage for blood to flow from a heart chamber to a coronary artery, at a site distal to the blockage or stenosis in the coronary artery. The conduit has a one-way valve positioned therein to prevent the backflow of blood from the coronary artery into the heart chamber.

US Classification:

604 9, 606153, 623 124, 623 2368

Abstract:

A method of flowing blood from a heart chamber to a coronary vessel includes providing a conduit with a first end and second end, providing the conduit within a heart wall such that the first end of the conduit is open towards the heart chamber and the second end is open towards the blood vessel, and during diastole, restricting a flow of blood from the coronary vessel to the heart chamber via the natural valve.

Abstract:

A stent suitable for implantation in myocardial tissue to enhance perfusion therein may include a tubular member having first and second ends and a lumen. The first end of the stent may be configured to pierce myocardial tissue and the lumen may be configured to be placed in flow communication with a coronary vessel. The stent may further include a means for retaining the tubular member within the myocardial tissue. A method for implanting the stent may include positioning the first end of the stent at a desired implantation site and applying force to the second end of the stent to implant the stent within the myocardial tissue. The method may further include engaging the means for retaining with the myocardial tissue to retain the stent in position.

US Classification:

623 237, 623 115, 604 8

Abstract:

A conduit is provided to provide a bypass around a blockage in the coronary artery. The conduit is adapted to be positioned in the myocardium or heart wall to provide a passage for blood to flow between a chamber of the heart such as the left ventricle and the coronary artery, distal to the blockage. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. Various attachment means are provided to anchor the stent and prevent its migration.
