摘要： A method and system for shrinking dilatations of a body, removing excess, weak or diseased tissue, and strengthening remaining tissues of the lumen walls. A catheter is disposed near the dilatation and fixed in position by inflatable occlusion balloons. Body fluids present in the occluded dilatation are evacuated and treatment fluid is exuded under pressure into the dilatation. Pressure is maintained by the treatment fluid while energy is applied by the catheter to heat the treatment fluid, causing the lumen walls to absorb the treatment fluid. Additional energy is then applied so as to preferentially heat the lumen wall tissues which have absorbed the treatment fluid, while at the same time treatment fluid is circulated to cool the inner surface of the lumen walls. The dilatation is occluded, a saline solution is introduced and absorbed into the lumen-wall tissue in the occluded region of the dilatation and then heated by application of radio frequency ("RF") or other energy in order to soften only the lumen-wall tissue of the dilatation, the dilatation is shrunk by application of a chilled saline solution and a vacuum, and additional RF or other energy is emitted to ablate, further shrink, and harden only the lumen-wall tissue of the dilatation, without destroying the inner surface of the lumen or other tissues of the body beyond the lumen walls, thereby promoting the growth of epithelial cells.

摘要： A method and system for treating aneurysms by applying RF energy to collagen. A catheter is disposed near the aneurysm and collagen is exuded into or near the aneurysm. RF energy is applied, using the same catheter or a second catheter, to the collagen, causing the collagen to harden and cover the weak region of the blood vessel wall, and providing a base onto which epithelial cells of the blood vessel may grow. The catheter comprises an electrophysiology catheter, including a ring electrode preferably disposed to deliver between about 5 and about 30 watts of RF energy at a frequency preferably between about 450 and about 600 Megahertz, to apply sufficient energy to cause the collagen to harden while avoiding damage to surrounding tissue.

摘要： An apparatus for ablating an inner layer in an organ or lumen of a body, or any desired thin layer. The ablation apparatus includes a balloon-like expandable member (12) (the balloon hereinafter) having an interior section for housing an electrolytic solution, a conforming member (20) made of a material such as a resilient foam rubber (the foam rubber hereinafter). Capable of substantially conforming to a portion of the inner layer of the organ. The foam rubber delivering the electrolytic solution housed within the balloon to the inner layer of the organ, one or more electrodes (39, 41) positioned in or on the foam rubber for delivering RF energy to the inner layer of the organ, an electrical connector device connecting the one or more electrodes to an RF energy source and an electrolytic solution delivery tube for delivering the electrolytic solution from the electrolytic solution source to the balloon. The apparatus may also include a feedback device which monitors a characteristic of the inner layer and, in response, controls the delivery of RF energy to the one or more electrodes. The one or more electrodes may be positioned in or on the foam rubber for delivering RF energy to the inner layer of the organ, each electrode including an insulator formed on a surface of the electrode. The foam rubber may also include 'non'-zone areas with a first porosity rate for delivering electrolytic solution to the inner layer and zone areas for housing an electrode and electrolytic solution, the zone areas having a second porosity rate that is less than the first porosity rate such that the electrolytic solution passes through the zone areas at a slower rate than through the non-zone areas. The ablation apparatus may also include a membrane positioned between the balloon and the foam rubber, the membrane adapted to receive the electrolytic solution from the balloon and deliver the electrolytic solution to the foam rubber.

摘要： A method and system for shrinking dilatations of a body, removing excess, weak or diseased tissues, and strengthening remaining tissues of the lumen walls. A catheter is disposed near the dilatation and fixed in position by inflatable occlusion balloons. Body fluids present in the occluded dilatation are evacuated and treatment fluid is exuded under pressure into the dilatation. Pressure is maintained by the treatment fluid while energy is applied by the catheter to heat the treatment fluid, causing the lumen walls to absorb the treatment fluid. Additional energy is then applied so as to preferentially heat the lumen wall tissues which have absorbed the treatment fluid, while at the same time treatment fluid is circulated to cool the inner surface of the lumen walls. The dilatation is occluded, a saline solution is introduced and absorbed into the lumen-wall tissue in the occluded region of the dilatation and then heated by application of radio frequency ('RF') or other energy in order to soften only the lumen-wall tissue of the dilatation, the dilatation is shrunk by application of a chilled saline solution and a vacuum, and additional RF or other energy is emitted to ablate, further shrink, and harden only the lumen-wall tissue of the dilatation, without destroying the inner surface of the lumen or other tissues of the body beyond the lumen walls, thereby promoting the growth of epithelial cells.
