  • Publication number: 20050004505
    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.

  • Publication number: 20040186507
    Abstract: Described herein are various methods and apparatuses for delivering stents 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.

  • Publication number: 20040147869
    Abstract: Left ventricular conduits and related methods are disclosed for achieving bypass of a partially or completely occluded coronary artery. More broadly, conduits for allowing communication of bodily fluids from one portion of a patient's body to another and related methods are disclosed, including conduits for forming a blood flow path from a chamber of the heart to a vessel or from one vessel to another. In other embodiments, the conduits achieve a coronary artery bypass by allowing blood communication between the left ventricle and the coronary artery or between a proximal portion of the coronary artery and a distal portion of the coronary artery. The conduits may be placed completely through the heart wall or extend only partially therein. Conduits may take on a variety of configurations for allowing the control of blood flow therethrough, including curved or tapered shapes.

  • Patent number: 6695877
    Abstract: A bifurcated stent comprises a first stent section and a second stent section. Each stent section is expandable from a predeployed state to a deployed state independently from one another. The second stent section having an end engaged to a receiving region of the first stent section. In the deployed state the first stent section defines a primary flow path and the second stent section defines a secondary flow path in fluid communication with the first flow path. At least a portion of one or both the first stent section and second stent section is constructed from a wire member.

  • Publication number: 20030216679
    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.

  • Publication number: 20030139764
    Abstract: The radially expandable frame utilized during catheterization includes a guide wire, a radiopaque radially expandable frame with distal and proximal frame ends wherein the guide wire freely passes through the proximal frame end, an elongated actuation sleeve having a flexible distal end piece (coil strain relief) through which freely passes the guide wire, and a friction locking mechanism located at the proximal end of the system which is defined by the proximal ends of the actuation sleeve and guide wire. The expandable frame includes radiopaque frame struts and has a closed, radially compact form and an open, radially expanded form. The actuator flexible end piece is a coil which enables the system to flex in excess of 90 degrees. The actuator sleeve, at its proximal end, includes a friction locking mechanism having locking members with respective locking surfaces.

  • Publication number: 20030125765
    Abstract: An emboli filter for deployment in a body lumen to capture emboli entrained in a fluid flowing through the lumen includes a flexible elongated member sized to be passed through the lumen. A filter media is carried on and substantially surrounding the elongated member. The filter media has a first end secured to the elongated member adjacent the distal end. A second end of the filter media has a periphery movable toward and away from the elongated member. Opposing internal surfaces of the filter media define a volume into which emboli may flow through the second end when the periphery is moved away from the elongated member. The emboli are trapped within the volume when the periphery is moved toward the elongated member. An actuator moves the periphery toward and way from the elongated member. The actuator includes a plurality of elastic loops. The loops are biased to an open loop configuration with the loops urging the periphery away from the elongated member.
