  • Patent number: 6567695
    Abstract: An electro-acupuncture device for controlling nausea. The device includes a base unit which is includes a wrist-watch like housing, circuitry for generating electro-acupuncture stimulus disposed within the housing, and a strap for securing the housing to the wrist. The base unit has a standardized construction. The device also includes a releasably attachable electrode assembly. The electrode assembly attaches to the base unit of the device. The electrode assembly includes a pair of electrodes and connectors for connecting the electrodes to the circuitry of the base unit.

  • Patent number: 6551255
    Abstract: A device and method of use for securing and coring of tumors within the body during a biopsy of the tumor, specifically breast tumors. An adhesion probe for securing the tumor is described. The probe secures the tumor by piercing the tumor and providing a coolant to the distal tip to cool the tip. The cooled tip adheres to the tumor. A coring instrument adapted for cutting a core sample of the tumor is described. The instrument is provided with a cannula that can cut a core sample of the tumor. The instrument is adapted for use with the probe with the probe fitting within the cannula. The instrument can be used in conjunction with the probe to secure and core a sample of the tumor for biopsy.

  • Patent number: 6547787
    Abstract: A drug delivery catheter suited for cardiac procedures including transmyocardial revascularization. The catheter includes a distal helical coil or other fixation and penetrating element, which can be operated from the proximal end of the catheter to engage and penetrate the myocardium. Once delivered to the inside of the heart, the catheter can be used to created several helical wounds in the myocardium, and also inject small doses of therapeutic agents to the wounds. The TMR accomplished by the procedure provides for large wound to penetration ratio, and limits the potential of perforating the heart wall.

  • Patent number: 6535241
    Abstract: The multi-person stereo display system permits several independent viewers to see different stereo images on a single projection surface. This is accomplished through the innovative use of video multiplexing, software, control electronics, and special viewing glasses. The system is particularly useful in situations where the viewers see computer generated images from their own independent perspectives.

  • Patent number: 6520071
    Abstract: A hand-held suction pump for creating a vacuum in a container (2) provided with a suction valve (3), comprising an elongated outer casing in which an electric motor (7) and a piston pump (14, 15) driven by the motor (7) are accommodated, wherein the pump chamber (14) of the piston pump is connected by an inlet valve and a suction duct (28) to a hollow tip (34) at the free end of the casing for direct coupling with the suction valve of the container, the pump chamber being further connected by an outlet valve to an exhaust duct (29) having a duct opening on the outer surface of the wall of the outer casing for porting an exhaust flow to the exterior of the outer casing. In order to reduce noise caused by the exhaust flow, the duct opening of the exhaust duct (29) is overlapped by a baffle (38) which is separated by a gapped distance from the outer surface of the wall of the outer casing so as to deflect the exhaust flow exiting the duct opening by a substantial angle.

  • Patent number: 6511471
    Abstract: A system and method for delivering a drug to a target site within a patient's body. The system and method include a steerable guide catheter and a drug delivery catheter. The steerable guide catheter has a first extension tube and a second extension tube that are joined together and form a shoulder. The delivery catheter has a distal docking segment and a proximal docking segment. The guide catheter is inserted into the patient's body, then the delivery catheter is inserted into the guide catheter. The distal docking segment engages the first extension tube, the proximal docking segment engages the second extension tube, and the shoulder limits the distance the delivery catheter can be inserted into the guide catheter. Also, once the delivery catheter is inserted it can be rotated to attach the helical tip to the target site. The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism.

  • Patent number: 6511477
    Abstract: A method of treating the heart and other body tissues by injecting a compound comprised of microsphere encapsulated macromolecule therapeutic agents into the myocardium, such that the microsphere size inhibits capillary transport of the compound but may permit lymphatic transport of the compound, and the compound releases therapeutic agents upon degradation of the microsphere. The compounds may be used in a method of treating the coronary arteries in which lymphatic transportable therapeutic agents are injected into the myocardium at a location distal to a target site in the coronary artery, after which they are taken up by the lymphatic vessels and transported proximally relative to the coronary artery, and migrate from the lymphatic vessel to the coronary blood vessel.
