摘要： A method for cooling of a brain with localized hypothermia allowing for maintenance of the core body temperature is achieved by positioning a cooling catheter within a ventricular cavity of the brain. The cooling catheter includes an inlet channel and an outlet channel providing for a closed flow of a cooling fluid into and out of the cooling catheter. A sack is formed at a distal end of the cooling catheter. The sack is in fluid communication with distal ends of the inlet channel and the outlet channel such that the sack is continually flushed with the cooling fluid as the cooling fluid flows into and out of the cooling catheter. The sack, when filled, takes the shape and size of the ventricular cavity filling the ventricular cavity in which it is positioned. The method further includes cooling the cooling catheter and the ventricular cavity through the closed flow of the cooling fluid through the cooling catheter.

摘要： A surgical instrument for cutting and grasping tissue comprising a handle assembly, an elongated member and first and second jaws. A first movable member moves the second jaw in a first direction about a first pivot axis in a grasping action and a second movable member moves the second jaw in a second direction different than the first direction and about a second pivot axis in a cutting action. A switch is positioned at the proximal portion of the instrument and a selecting member is actuated by movement of the switch, the selecting member movable between a first position to enable movement of the second jaw in the first direction and prohibit movement in the second direction and a second position to enable movement of the second jaw in the second direction and prohibit movement in the first direction.

摘要： A surgical portal and introducer assembly includes an introducer dimensioned for at least partial positioning within a tissue tract, and having a longitudinal introducer channel extending therethrough and a portal positionable within the longitudinal channel of the introducer. The introducer defines leading and trailing ends, and further has a frangible segment adapted to separate to expose the introducer channel. The portal has at least one longitudinal port for passage of a surgical object. The portal comprises a compressible material and is adapted to transition from a first expanded condition to a second compressed condition upon advancement through the longitudinal channel of the introducer to facilitate passage through the introducer whereby, upon separating of the frangible segment, the portal is released from the longitudinal channel to transition toward the first expanded condition to be generally secured within the tissue tract.
