Abstract: A balloon catheter having a blood pressure sensor connected to the catheter and also a fluid-filled transducer system for adjusting the blood pressure sensor measurements.

Abstract: An apparatus for adjusting the body temperature of a patient comprises an enclosure defining an interior space for receiving at least a portion of a patient's body therein. The enclosure is adapted for substantially sealingly enclosing the portion of the patient's body within the interior space with the enclosure. Heat transfer liquid may then be circulated through the interior space of the enclosure via an inlet and an outlet for flow over the patient's body in direct liquid contact therewith to promote heat transfer between the patient's body and said heat transfer liquid. The heat transfer liquid may be either warmer or cooler than the patient's body temperature, to either warm or cool the portion. Controlled cooling may be employed to induce therapeutic hypothermia, while controlled warming may be employed to counteract unintended hypothermia.

Abstract: An intra-aortic balloon catheter having a collapsible variable diameter inner tube.

Abstract: A single lumen monorail intra-aortic balloon catheter and guide wire system. The catheter and guide wire being advanced through a patient's vasculature as a unit. The guide wire comprising a tip guide section and a pull section configured so as to minimize bleeding at the insertion site.

Abstract: A balloon catheter having a micromanometer connected to the catheter and also a fluid-filled transducer system for adjusting micromanometer pressure measurements.

Abstract: A reduced size IAB catheter system comprising an IAB catheter disposed within a tube serving both as a insertion sheath and as a reinforcement tube. The tube is preferably disposed about the entire catheter up to the balloon membrane. The catheter remains disposed within the tube during therapy.

Abstract: An active compression/decompression CPR device includes two pressure members mounted on a common beam. When placed on the victim with one member on the chest and the other on the abdomen, pressure on one end of the beam causes compression of the thorax and decompression of the abdomen. Conversely, when pressure is applied to the other end of the beam, the abdomen is compressed and the thorax is decompressed.

Abstract: A preassembled PBY circuit includes a blood pump, an oxygenator, a blood line, a filter/trap, a cannulae line subassembly, and a return line. The blood pump, oxygenator, blood line, filter/trap, cannulae line subassembly, and return line are serially arranged in a closed loop configuration, and a prime line is attached in fluid communication with the circuit. The cannulae line subassembly includes a first cannula line attached to the return line, a second cannula line attached to the filter/trap, and a removable connector for connecting the first and second cannulae lines in fluid communication. Each of the cannulae lines is prearranged in a helical configuration. The circuit is arranged for suspension, such that, when suspended, the filter/trap is located at a high point of the circuit, and the prime line is attached at a low point of the circuit.

Abstract: An active compression/decompression CPR device capable of providing both complete cardiopulmonary support and cardiopulmonary assistance includes two or more thoracic compressors, preferably inflatable bladders, positioned so that the chest can first be flattened and compressed, increasing the pressure in the chest, and then circularized and decompressed, decreasing the pressure in the chest. When inflatable bladders are used, they can be surrounded with a rigidifying vest which resists outward bladder expansion. Compression and decompression can be performed along with abdominal compression, and the device is capable of shifting between support and assist modes when the patient's condition so requires.
