  • Patent number: 6241744
    Abstract: An apparatus for deploying a guidewire across a complex lesion in a vessel formed by a wall and normally having a lumen extending therethrough including an elongate flexible catheter having proximal and distal extremities and having a plurality of separate spaced apart lumens therein extending from the proximal extremity into a location at least adjacent the distal extremity. A handle is mounted on the proximal extremity of the flexible elongate catheter. A flexible elongate sheath is mounted on the catheter and has a proximal portion, a transition portion and a distal portion with the transition portion being in the vicinity of the distal extremity of the catheter. The sheath has a lumen therein extending from the proximal portion through the transition portion and through the distal portion.

  • Patent number: 5688234
    Abstract: Apparatus for the treatment of a thrombotic occlusion in a vessel of a patient comprising a flexible elongate tubular sheath having proximal and distal extremities. A relatively large lumen defined by a thin flexible wall extends from the proximal extremity to the distal extremity of the tubular sheath so that the distal extremity is open. An occlusion disruption device is slidably and rotatably disposed in the lumen in the tubular sheath and includes a flexible elongate torsionally rigid shaft having a length greater than the length of the tubular sheath and having proximal and distal extremities. The shaft has a guide wire lumen extending from the proximal extremity to the distal extremity. Disruption elements are secured to the distal extremity of the shaft which when rotated disrupt the thrombotic occlusion by causing it to break into pieces. Suction is applied to the lumen in the tubular sheath to aspirate pieces into the large lumen of the tubular sheath to remove them from the vessel of the patient.

  • Patent number: 5517989
    Abstract: A method of diagnosing and treating the human or animal body comprises feeding a flexible guide wire, dimensioned to be inserted into human coronary arteries, along a blood vessel in the human or animal body and epicardially mapping the electrocardiographic signals by means of electrodes secured to the guide wire. The method of diagnosing and treating the human or animal body may include the step of ablating selected body tissue by establishing a DC or radio frequency current through the body tissue between a pair of electrodes in which at least one of the electrodes is located on the guide wire. The method may also include passing flowable material to or from selected tissue by means of a catheter passed over the guide wire. The method may optionally include sensing the velocity of blood flow in the blood vessel by means of a velocity sensor mounted on the guide wire, or the temperature of selected body tissue by means of a temperature sensor mounted on the guide wire.

  • Patent number: 5121749
    Abstract: Apparatus for measuring the volumetric flow of a liquid in a vessel having a wall and having an axis extending longitudinally of the vessel parallel to the vessel wall. A flexible catheter is provided which has a longitudinal axis adapted to be disposed in the vessel. The catheter has front and back sides. First, second, third and fourth transducers are carried by the catheter. The first, second and fourth transducers are disposed on the front side of the catheter and the third transducer is positioned on the back side of the catheter.

    Abstract: Low profile dilatation catheter having an elongate flexible tubular member with proximal and distal extremities and with a flow passage extending therethrough. An inflatable balloon is mounted on the distal extremity of the elongate flexible tubular member so that the balloon has its interior in communication with the flow passage in the tubular member. A flexible tip is secured to the distal extremity of the balloon. A core wire extends through the elongate flexible member and has proximal and distal extremities. The distal extremity of the core wire is tapered and extends through the balloon and into the flexible tip. The distal extremity of the core wire is secured to the flexible tip. A rotator is provided for rotating the proximal extremity of the core wire for causing rotation of the flexible tip. Self-venting means is provided for venting the balloon to ambient. An adapter is carried by the proximal extremity of the elongate tubular member.

  • Patent number: 4641654
    Abstract: Steerable balloon dilatation catheter assembly having dye injection and pressure measurement capabilities and comprising an elongate flexible tubular member having first and second lumens extending therethrough and a balloon carried by the distal portion of the tubular member and having its interior in communication with the second lumen. A guide wire extends through the first lumen and has a coil carried by the distal portion thereof and extending beyond the distal extremity of the tubular member. A device is coupled to the guide wire facilitating at least limited rotation of the distal extremity of the guide wire. A first fitting is coupled to the second lumen and is adapted to receive a liquid for inflating and deflating the balloon. A second fitting is in communication with the first lumen.

  • Patent number: 4619263
    Abstract: Adjustable rotation limiter device for use with a steerable balloon type dilatation catheter of the type having a flexible core wire extending therethrough and an adapter adapted to be secured to the proximal extremity of a dilatation catheter. The adapter has at least a first arm with a fitting thereon. A sealing is disposed within the fitting. A thumb screw having a first knob carrying a threaded axially extending member is threaded into the fitting and is adapted to engage the seal whereby when a core wire extends through the fitting, the seal, and the thumb screw, the rotation of the thumb screw in one direction will cause sealing engagement between the seal and the core wire. A torque knob having a second knob carrying an axially extending member is threaded into said thumb screw. A rotation limiter is carried by one of the knobs and has a portion thereof extending over the other of the knobs which serves to limit the rotational movement of the second knob with respect to the first knob.

  • Patent number: 4616653
    Abstract: Balloon dilatation catheter with an advanceable non-removable guide wire having a flexible tubular member with first and second lumens extending therethrough. An inflatable balloon is carried by the distal extremity of the tubular member so that the first lumen extends through the balloon and is out of communication with the interior of the balloon and in which the second lumen is in communication with the interior of the balloon. A guide wire is slidably mounted in the first lumen. A coil-like tip is secured to the distal portion of the guide wire and has a cross-sectional area which is greater than that of the cross-sectional area of the first lumen and prevents removal of the guide wire through the first lumen. The guide wire is capable of being advanced longitudinally of the first lumen so that the coil-like tip of the guide wire can be advanced ahead of the balloon to facilitate the positioning of the balloon.

  • Patent number: 4573470
    Abstract: Low-profile steerable intraoperative balloon dilatation catheter with a flexible core wire having proximal and distal extremities. A flexible tube extends over the core wire and has proximal and distal extremities with the distal extremity being bonded to the distal extremity of the core wire to form a liquid-tight seal. A balloon is carried by the distal extremity of the flexible tube. The flexible tube provides a lumen extending from its proximal end into the balloon. An adapter is secured to the proximal ends of the core wire and the flexible tube. The adapter has at least first and second arms with the core wire extending through the first arm and the lumen being in communication with the second arm.
