摘要： A system utilizes an oxygenation device to generate a gas-enriched physiologic fluid and to combine it with a bodily fluid to create a gas-enriched bodily fluid. The oxygenation device may take the form of a disposable cartridge, which is placed within an enclosure. An electronic controller manages various aspects of the system, such as the production of gas-enriched fluids, flow rates, bubble detection, and automatic operation and shut down.

摘要： A minimally-invasive surgery apparatus for causing the lumen of a vein to collapse to prevent blood flow through the vein, e.g., a varicose vein or a side branch of the saphenous vein, includes an electrode which is electrically connected to a power source, and the electrode is percutaneously advanced into the vein. Then, the power source is activated to energize the electrode and thus the blood vein until the blood vein sufficiently collapses to block the lumen of the vein. A feedback loop is also provided for sensing electrical impedance of the tissue within the vein being energized and for deenergizing the electrode when the impedance reaches a predetermined value. The apparatus can also be used to block a fallopian tube.

摘要： An apparatus for in situ saphenous vein bypass includes an operating catheter which includes an optical fiber and an electrode, and a control catheter which includes a valvulotome. The operating catheter and control catheter are locked together and advanced through an incision in the leg. The catheters are closely spaced from each other, on opposite sides of a valve to be disrupted. Then, the valvulotome is manipulated to disrupt the valve, the electrode is manipulated to stanch blood flow from the valve and to close off side branches, and both procedures are viewed by means of the optical fiber. The valves of the saphenous vein are thusly disrupted in sequence, and the side branches to the saphenous vein closed off, to thereby modify the saphenous vein in situ for arterial use. In alternate embodiments, the electrode is used with delivery catheters to stop blood flow through a side branch or varicose vein. The electrode includes an embedded temperature sensor for sensing electrode temperature.

摘要： An ultrasonic tissue resector is slidably engaged with a working channel of a flexible neuroendoscope for resecting brain tumors, cysts, hematomas, and herniated spinal discs. The resector includes a piezoelectric transducer for generating ultrasonic energy. The ultrasonic energy is coupled to an ultrasonic probe having a rigid proximal segment for transmitting the energy therealong and a flexible distal segment which can bend to conform to the flexible neuroendoscope. An aspiration channel is provided, and the resector can be endoscopically positioned in the brain through the neuroendoscope and energized to ultrasonically break up tissue such as tumors, cysts, and hematomas and remove the tissue through the aspiration channel.
