  • Patent number: 8262567
    Abstract: A tissue retractor for retracting tissue opened by an incision, the tissue retractor including a base support unit having a topside and an underside. The topside has at least one securing mechanism and the underside is conformable and removably attachable to a surface proximate to the incision. The tissue retractor has a tissue hook having a tissue engagement portion and a mounting portion, the tissue engagement portion capable of engaging at least the periphery of the incision. The tissue retractor has a retractable member substantially inelastic in its central longitudinal axis and bendable in any axes deviating from the central longitudinal axis. The retractable member receives the mounting portion of the tissue hook, the retractable member being removably attachable to said securing mechanism on the topside of the base support unit, and being retractable away from the incision, such that the tissue engagement portion retracts tissue engaged thereto.

  • Publication number: 20100241213
    Abstract: A pump installed inside a graft in a body such as the human body to force fluid such as blood through that graft. The pump can be one which operates totally from the outside of the graft, forcing fluid through the graft without extending inside the graft. The pump can be an impedance pump, that operates based on the fluidic mismatches between the graft, and other fluid carrying vessels within the human body.

  • Publication number: 20060276682
    Abstract: A percutaneous cannula is provided that directs blood into a vessel of a patient. The cannula includes a main cannula portion and a tip portion. The tip portion directs blood-flow in a direction generally counter to the direction of flow through the lumen. The cannula is configured to prevent blood-flow exiting the distal end from immediately discharging against a wall of the vessel.

  • Publication number: 20040122362
    Abstract: A method for draining and sealing a pseudo aneurysm in which a guide wire is inserted over a needle. Then a multi-lumen catheter is inserted over the guide wire. The catheter is used to occlude the vessel puncture and inhibit the flow of fluids between the vessel and the pseudo aneurysm. The pseudo aneurysm is then aspirated and the vessel puncture is allowed to clot and heal.
