  • Patent number: 5893369
    Abstract: A bypass procedure for connecting a bypass conduit to a blood vessel to channel a flow of blood around an occlusion. The procedure involves attaching a bypass conduit to a portion of the blood vessel at first and second locations. A collar is utilized to suture the graft to blood vessel. A punching device is inserted into one of end of the bypass conduit. The punching device preferably includes a punch and a block. The block is inserted through a cut formed in the blood vessel wall. Concomitant actuation of the block and punch toward one another severs a section of the blood vessel wall to form a channel into the bypass conduit. The present invention also discloses preferred implements for use in the bypass procedure. A cutting device can be utilized to form the cuts in the vessel wall and may be either integral with or separate from the block. In one embodiment, the block is expandable between a collapsed state and an expanded or inflated state.

  • Patent number: 5824069
    Abstract: A prosthetic heart valve, either of the mechanical type, or the bioprosthetic type, comprises a circular frame element, a check valve element and a suturing member surrounding the circular frame element. The circular frame element defines a circular opening for the passage of blood therethrough. The check valve element is connected to, and extends across, the circular frame element and is configured to substantially permit the flow of blood through the circular opening in a first direction and to substantially impair the flow of blood through the circular opening in a second direction opposite the first direction. The suturing member surrounds the circular frame element and has a first radial width in a first circumferential region substantially greater than a second radial width in a second circumferential region to define an extended portion of the suturing member.

  • Patent number: 5554173
    Abstract: A defibrillator charge tester includes a generally fork-shaped nonconductive shell defining two prongs and a handle. A charge testing circuit is disposed in the shell. The circuit terminates at two ends. A conductive plate-shaped contact member is disposed at each of the two ends, external to the shell. In use, the contact members touch respective defibrillator electrode surfaces. The circuit includes a fuse to prevent reuse of the tester.

  • Patent number: 5342375
    Abstract: The present invention provides an apparatus which is designed to capture, and manipulate the movement of, surgical needles as they pass through the tissue wall of a patient. The apparatus of the present invention has, among other things, a removable gripping body component which is designed to rest against the tissue wall of a patient. This gripping body component has sufficient resistance to be penetrated by, and grip, the needle's point. The apparatus also has a component which is designed to manipulate the movement of the gripping body component. This manipulating component has a ledge surface or opening defined thereon or therein. The apparatus also has a fastening component. At least one end of the fastening component is secured to the gripping component. The fastening component is designed to secure the removable gripping component to the manipulating component.

  • Patent number: 5019604
    Abstract: A protective gel composition is disclosed for coating skin surfaces, particularly the hands of the surgical attendants prior to covering the hands with standard surgical gloves. In one example, the composition comprises controlled proportions in mixture by weight of lanolin, a liquid silicone, polypropylene glycol mono-oleate, polytetrafluoroethylene powder in microspherical form and zinc oxide powder. Anti-microbial and anti-viral agents may be further added to fortify the coating of the composition, with a preferred such agent being nonoxynol-9. The sterilized composition is applied to the hands after scrubbing and just prior to insertion into the gloves. The coating is water-repellent to prevent skin contact with body fluids, such as blood and blood products, that may penetrate the gloves and otherwise expose the skin to harmful microbial and viral infections. When the gloves are removed following the surgical procedure, the coating is easily removed with an alcohol and liquid detergent wash.
