摘要： An intravascular catheter device having a catheter and an ultrasound ablation manifold is proposed for generating cavitations and acoustic jet streams in the blood to ablate atheroma. The ablation manifold has a power transducer and a coupled leaky acoustic cavity. The leaky acoustic cavity contains a first portion of ultrasonic power emission for intra-cavity ablation while allowing a second portion of ultrasonic power emission to leak outside for an extra-cavity ablation. The power transducer and the leaky acoustic cavity are configured to form a confocal resonant cavity. An intervening bird cage is coupled to the resonant cavity for stronger resonance while maintaining ultrasound leakage. A protective shield is mounted around the waist of bird cage to strengthen resonance and to prevent damaging the intima from an otherwise normal incidence of high intensity ultrasound. A microbubble releasing device and micro pump are also included to further increase the ablation efficacy.

The tubular body defines a central lumen having a central lumen diameter. The ultrasound catheter further comprises an elongate, hollow inner core extending through the central lumen. The elongate, hollow inner core has an inner core outer diameter that is less than or equal to the central lumen diameter. The ultrasound catheter further comprises an ultrasound radiating member positioned within the distal region of the tubular body and between the tubular body and the inner core. The ultrasound catheter further comprises at least two electrical conductors extending between the tubular body proximal region and the tubular body distal region. The at least two electrical conductors are positioned between the tubular body and the inner core. The at least two electrical conductors are electrically connected to the ultrasound radiating member. The at least two electrical conductors are wrapped around the inner core a plurality of times in a region between the ultrasound radiating member and the tubular body proximal region.

摘要： The present invention improves significantly the success rate of lithotripsy and reduces the risk of tissue damage, by injecting temporary plugs in front and behind a concretion (for extracorporeal lithotripsy) or behind a concretion (for intracorporeal lithotripsy). One aspect of the present invention relates to injecting an inverse thermosensitive polymer solution into a lumen, thereby preventing the migration of a concretion, or its fragments, upon extracorporeal or intracorporeal lithotripsy.

摘要： A cardiovascular treatment method utilizes an elongate flexible surgical instrument (e.g., catheter) having a distal end. A distal end portion of the instrument is inserted into a vascular system of a patient. A surgical head at the distal end of the instrument is positioned so that the head is disposed adjacent to myocardium tissue of the patient. The head is operated to form a recess in the myocardium tissue. Prior to operating the head to form the recess, a thickness of the myocardium tissue is measured, the recess formed during the operation having a length determined in accordance with the measured thickness of the myocardium tissue. The thickness measurement partially determines the length of the recess. The angle of entry of the recess with respect to the heart wall also partially determines the length of the recess: the greater the angle, the longer the recess can be for a given myocardium thickness.

摘要： Methods of improving the circulation of blood to the muscle of the heart of a patient are disclosed. In a first method, a guidable elongated flexible ultrasound device is inserted into a patient's vasculature, and its distal end guided to an area of interest within the patient's heart to which increased blood flow is desired, where ultrasonic energy is applied to the area of interest via the distal end. In a second method, a distal end of an ultrasound device is directed into a patient's chest cavity, and guided within the patient's chest cavity to engage an exterior area of interest of the patient's heart to which increased blood flow is desired, where ultrasonic energy is applied to the area of interest via the distal end.

摘要： An ultrasonic medical apparatus, particularly convenient for use inside a body cavity, includes an applicator having an ultrasonic transducer, which may be attached to an acoustic lens such that the emitted ultrasonic waves are focused at two or more different positions. For this purpose, the wave-emitting surface of the transducer, or the acoustic lens attached to it, is partitioned into concave surface elements which may be in a concentric annular arrangement and may each have a different radius of curvature and a different center of concavity. An apparatus thus structured can be made compact and hence is convenient for use inside a body cavity.

摘要： A method for the treatment of the prostate gland which heats the tissues which would otherwise be surgically removed with a trans-urethral resection of the prostate. This method is accomplished by combining a radiating energy device integrated with a urinary drainage Foley type catheter, which is modified to provide cooling along the urethra surfaces. The radiating device also serves as a means to measure the tissue radiated thermal energy for the control or monitoring of temperature of the prostate tissues being heated. A urethral inserted applicator for prostate hyperthermia includes a multi-tube, balloon type catheter. The catheter includes a fluid dry tube for an energy radiator antenna applicator which also serves as a radiometric temperature sensor for measuring the temperature of the prostate tissue, and an open fluid receiving tube. An electromagnetic energy generator supplies electromagnetic energy to the applicator. A comparator is connected to the temperature output of the radiometer, and a temperature reference potentiometer for comparing the actual tissue temperature level with a desired temperature level and outputting control signals to the electromagnetic generator for controlling the output to the applicator. The microwave operated applicator is preferably an elongated coil having the tip end connected to the center conductor of a coaxial cable and the opposite end connected to the outer conductor of the coaxial cable. A sheet or sheath of insulation material covers the microwave coil antenna for insulating the coil from the tissue and the thickness of the sheet may be varied to provide uniform tissue heating along the length of the coil. The ultrasound operated applicator is preferably one or more ultrasound crystal cylinders to radiate energy into the tissue and convert tissue thermal ultrasonic energy into electrical energy for measurement by a radiometer, The balloon of the catheter engages the body's bladder to position the applicator properly during the treatment.
