  • 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.

  • Patent number: 6776754
    Abstract: A cardiac insert or implant is deployed in a patient's heart so as to reduce ventricular volume, thereby improving cardiac function. The insert or implant may be a compressive device such as a tensile member inserted into the patient's heart, and thereafter operated or deployed to bring opposite walls of a ventricle of the patient's heart into at least approximate contact with one another to thereby constrict and close off a lower portion of that ventricle. The compressive device or tensile member is insertable into the patient heart via a catheter threaded through the patient's vascular system and into the patient's heart.

  • 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.

  • Publication number: 20040139801
    Abstract: A method for investigating structural integrity utilizes a carrier member having a flexible surface and a plurality of electromechanical transducer elements attached to the carrier member, the transducer elements being spaced from each other along at least two spatial dimensions. The method includes conforming the flexible surface to a solid structural member, so that a substantial portion of the flexible member is in effective wave-transmitting engagement with the structural member, thereafter transmitting pressure waves from at least one of the transducer elements into the structural member, receiving pressure waves reflected from an internal structural defect in the structural member in response to the pressure waves transmitted from the one of the transducer elements, and analyzing the received pressure waves so as to detect the structural defect.

  • Publication number: 20040059345
    Abstract: A medical cauterization snare assembly with a tubular member, an electrically conductive cauterization loop ejectable from a distal end of the tubular member, and a capture pouch also ejectable from the distal end of the tubular member. The pouch is attached to an auxiliary loop which has a size larger than that of the cauterization loop. Alternatively, the tubular member is formed at its distal end with a first port or opening and in a distal end portion with a second port or opening spaced from the first port or opening. The two ports or openings both face in a distal direction (i.e., away from the user). The cauterization loop is alternately ejectable from and retractable into the first port or opening, while the capture pouch is separately ejectable from the second port or opening. Alternatively, the capture pouch is attached to the cauterization loop, to only a proximal portion of the loop to divide the loop's area into a proximal section covered by the pouch and an open or uncovered distal section.

  • Patent number: 6695084
    Abstract: A personal transportation apparatus has a frame defining a surface for supporting a load, and a plurality of air-cushion cells mounted to the frame and depending from a lower side thereof, the air-cushion cells each having a changeable height to accommodate variations in an underlying terrain during a translation of the frame over the terrain. A pressure source is mounted to the frame and is operatively connected to the air-cushion cells for supplying air under pressure to the cells, thereby generating an air-cushion support for the frame. An elevation mechanism is mounted to the frame for lifting the frame from one step to a next higher step of a stairway so that the frame ascends the stairway from a lowermost step to an uppermost step of the stairway.

  • Publication number: 20030212413
    Abstract: Described herein is a catheter system for delivering an L-shaped conduit into the body of a patient between the left ventricle and coronary artery. A shunt preferably made of semirigid material is inserted into the lumen of a delivery catheter. The delivery catheter is advanced within the patient until its distal end is located adjacent to the desired insertion site, which is preferably the junction between a coronary artery and passageway formed in the myocardium between the left ventricle and coronary artery. A proximal section of the shunt is first advanced out of the delivery catheter into the myocardial passageway. A distal section of the shunt is advanced into the coronary artery, preferably by advancing the distal section of the shunt into the myocardial passageway and then. pulling the distal section back into the coronary artery, or by pushing the distal section of the shunt in a folded configuration out of the delivery catheter into the coronary artery.

  • Patent number: 6643124
    Abstract: A portable computing device is equipped with multiple display panels. The display panels and hinged, jointed or otherwise disposed to rotate or slide with respect to one another in a transition from a compact configuration to an expanded configuration. In a basic embodiment three output screens take a form of a triptych for which an input panel forms a base. The output panels are deployed with a bend when opened and images angled in towards an observer. The display panels comprise a main panel and two auxiliary panels. In a variation a forth display panel is rotatably or foldably joined to the central display panel so that a total of four display panels may be deployed in a hub and petal configuration. The side panels may be eliminated from the four panel embodiment so that the input panel and two remaining display panels form a vertically orientable triptych with the input panel serving as base.
