    摘要： A venting catheter, system and method are provided for withdrawing blood and other fluids from a patient's heart to facilitate decompressing the heart during cardioplegic arrest and cardiopulmonary bypass, without the need for a thoracotomy and without puncturing the aorta, pulmonary artery, or heart itself. The venting catheter is configured to be introduced into a peripheral vein and intraluminally advanced through the right side of the heart and into the pulmonary artery. The venting catheter includes a lumen configured to withdraw blood at a rate of at least about 50 ml/min at a pressure of no less than about −350 mmHg. A flow-directing means is provided to facilitate guiding the catheter into the pulmonary artery by being carried by blood flow through the heart. The cardiac venting system may include, in addition to the cardiac venting catheter, a cardiopulmonary bypass system to maintain circulation of oxygenated blood, and means for arresting the patient's heart.

    摘要： A balloon dilatation catheter for the dilatation of a prostatic urethra having a reinforcing element extending through the elongated shaft of the catheter to prevent significant elongation or failure of the catheter and a traction member for assisting in the resistance to substantial tensile stresses. The balloon dilatation catheter also includes an expandable means between the balloon and catheter shaft to extend the length of the balloon when it is deflated. The extension of the deflated balloon prevents the balloon from bunching up and interfering with the withdrawal of the balloon through the working channel of the cystoscopic sheath upon the completion of the dilatation. The catheter has a marker for easy visualization so that the balloon can be positioned reliably and a tip construction so that the catheter can be advanced into the bladder safely.

    摘要： A hand held device having an optical fiber with a radiation emitter carried at a free end, the optical fiber being attached to a handle that includes a knob which allows movement of a flexible tubular sleeve from a position covering the fiber and emitter to a position exposing the emitter and a length of fiber adjacent to it, the sleeve also having a sharp metal cleat extending from its end, the cleat being an end of a length of wire which passes through a separate channel of the sleeve to the knob without being attached to the sleeve. An application of this device is for inserting the emitter into a mass of material in order to irradiate the material from within.
