    摘要: An ultrasonic medical or surgical device creates holes in heart tissue utilizing an ultrasonic needle or probe. The ultrasonic needle is inserted into heart tissue and activated to cause cavitation of fluid surrounding the needle. The cavitation heats the surrounding tissue and causes reversible tissue damage. The ultrasonic device consists of a transducer, a needle, and a regulator. The device can be a hand held device for external application or may be a catheter device for performing a minimally invasive procedure. A temperature sensor may be positioned on the needle for sensing a temperature of the heart tissue in which the needle has been inserted.

    摘要: A device and method for treating collapsed bronchial tubes found in patients with chronic obstructive pulmonary disease and asthma are provided. The device includes an elongated member having a heating element that comprises one or more energy delivery members. The method includes heating the bronchial tube to cause at least a portion of the cross links of the collagen in the wall to unlink/open and subsequently form new cross links after the collagen fibers have realigned. The procedure effectively reinforces the structural integrity of the wall and thereby prevents the lumen from collapsing.

    摘要: A device and method for treating infected or damaged heart valve tissue by selectively heating, applying pressure, or both to the heart valve tissue to sterilize any infected portion of the tissue, reshape any misshapen portion, effect selective thinning of any thickened portion, and reduce the floppiness of any selected portion. The heat can be applied to or induced in the heart valve tissue.

    摘要: A device and method for shortening the chordae tendineae by heating them. Shortening the chordae tendineae stabilizes the atrioventricular valve to which they are attached, thus reducing or halting valve prolapse. A catheter having a heating tip system is inserted in the heart of a patient and maneuvered by an operating surgeon so that the heating tip can induce or transfer heat to the chordae tendineae. The heating tip system heats the chordae tendineae by direct transmission of heat or by inducing heat in the chordae tendineae with electromagnetic radiation. The operating surgeon monitors the heating of the chordae tendineae and when the desired degree of shorting has been achieved, the catheter is removed from the patient.
