  • Publication number: 20150119917
    Abstract: An endoscopic vessel harvester includes a vessel keeper for capturing a target vessel within a tunnel that has been dissected along the target vessel. A cutter member cuts and cauterizes side branches while the target vessel is slidably captured in the vessel keeper. A spray nozzle carried by the vessel keeper delivers a preservative fluid via a manual control valve and a conduit. The preservative fluid is sprayed on the target vessel proximate a respective side branch immediately after being cauterized. Thus, a harvested vessel is bathed in preservative fluid prior to being actually removed from the body, enhancing endothelial preservation from cascading events.

  • Publication number: 20140296622
    Abstract: Apparatus for marking a blood vessel for use as a bypass graft in a patient includes a preparation plate for supporting an isolated blood vessel that is in a state for anastomosing to the patient. A stencil plate is configured for overlying the blood vessel and preparation plate, wherein the stencil plate has an opening adapted to expose a portion of the blood vessel to a dye applied through the opening. The stencil plate around the opening is adapted to shield the blood vessel from the dye. A dye applicator is configured to direct a metered amount of the dye through the opening and onto the exposed portion of the blood vessel, preferably as a mist. Preferably, the opening is a lineal slot for creating a guide line extending longitudinally along an outer wall of the blood vessel.

    Abstract: A cutter for a blood vessel tissue harvesting instrument is disposed at the distal end of an insertion member. A cutter body projecting from the distal end of the insertion member includes a slit that extends from the distal end toward a base edge. High-frequency electrodes are disposed along the sides of the slit. A feeding mechanism has rotating surfaces which are rotated as a result of being pressed by the tissue, and which feed the tissue toward the base edge of the slit. The rotating surfaces are provided by two rotary members disposed opposite each other along the two side edges of the slit, respectively, so that the first and second rotating surfaces move in a direction from the opening of the slit toward the base edge of the slit.

  • Publication number: 20120229289
    Abstract: A system for clamping a flexible tube containing medical fluids includes a cable assembly coupled to a remote driver and a slidable clamp that imparts a clamping force to the flexible tube. An electrical continuity detector is included to measure the wear of an internal insulating layer of the cable between a sliding inner wire and a cable casing member. An indication of the wear to the cable is generated in response to a comparison of the electrical integrity of the insulating layer with a threshold. The wear indication enables the cable to be repaired or replaced prior to a malfunction of the overall tube clamp system.

  • Publication number: 20120232495
    Abstract: A system for clamping a tube includes a Bowden cable with an inner member and an outer casing. A first jaw element has a first tube abutment surface, a passage, and a first sliding latch portion. The inner member of the Bowden cable passes through the passage. A second jaw element has a second tube abutment surface, a cable guide, and a second sliding latch portion. The inner member has a first end which is held in the mated sliding latch portions so that sliding of the inner member results in selectably positioning the first and second tube abutment surfaces together or spaced apart. An actuator is coupled to a second end of the outer casing and a second end of the inner member for applying a force to slide the inner member within the outer casing, the passage, and the cable guide. The Bowden cable substantially isolates the tube being clamped from the weight of the actuator.

  • Publication number: 20120071736
    Abstract: A blood parameter measurement cassette or other device is configured to control incidental liquid discharged during the device's calibration process. The cassette includes optical sensors which are chemically responsive to blood constituents and require calibration with a blood parameter monitoring device prior to use in a medical procedure. During the calibration process, an incidental amount of a liquid may be expelled from the cassette. The present invention is directed towards controlling the expelled liquid by absorbing it using an absorbent material disposed on the exterior of the cassette's main body. The absorbent material thereby prevents the liquid from causing detrimental effects to the monitoring and calibration equipment used in conjunction with the cassette. The scope includes additional embodiments wherein the inventive concept is applied to other fluid-handling medical devices that require venting of gases.

  • Publication number: 20100292533
    Abstract: A bipolar cutter has a cutter main body for inserting into the interior of a body and a treating electrode that is positioned against an object of examination (such as a blood vessel or a bleeding site) to be electrically cut and cauterized. A guiding member guides the object of examination toward the treating electrode as it is displaced in the axial direction of the cutter main body. The guiding member is comprised of a pair of protruding members and a notched groove or gap that leads to the treating electrode while in a first configuration. A gap adjusting mechanism causes the guiding member or the treating electrode to be displaced in the axial direction to reduce or eliminate the length of the gap so that the treating electrode can better reach flat tissue surfaces for treatment.

  • Patent number: 7704221
    Abstract: A rotary valve unit is provided for blending fluid sources to regulate a temperature of fluid flowing to a heat exchange device in an extracorporeal blood perfusion circuit. A valve body includes a valve chamber having a first inlet port, a second inlet port, a first outlet port, and a second outlet port. A wedged-shaped rotary valve is disposed within the valve chamber and is rotatable within the valve chamber for controlling a blending of the cold fluid entering the fluid chamber from the first inlet port and the return fluid entering the fluid chamber from the second inlet port to regulate the desired temperature of fluid provided to the heat exchanger. The wedge-shaped rotary valve is positionable to provide either only cold fluid to the first outlet port, only return fluid to the first outlet port, or blending of the cold fluid and return fluid to the first outlet port.

  • Patent number: 7706853
    Abstract: A NIRS sensor device for brain monitoring is small in size, provides reliable attachment to a patient, blocks ambient light, is easy to use, is hygienic, and supports data integration with surgical and monitoring systems. The sensor device is coupled to a remote near infrared light source via a hybrid cable. Since the light source is remotely located, a source adapted for providing high energy, short pulses can easily be used so that there is less chance of interference by superficial non-brain tissues and less interference from ambient light. In addition, the remote location avoids changes in output of local light sources experienced in the prior art during hypothermia procedures (e.g., bandwidth shifts in LEDs as a result of lowered temperature). The higher energy may be achieved by the use of laser diodes as opposed to locally-mounted LEDs typically used in the prior art.
