摘要： A method and apparatus for reducing restenosis of a stenotic region of a blood vessel after performing dilation angioplasty treatment is disclosed. The method includes radiating microwave energy from a microwave antenna (52) to kill a medial tissue layer of the blood vessel in the stenotic region. The radiation is applied during or after inflation of dilatation balloon (18) to permanently dilate the stenotic region. When radiation is applied during dilatation of the stenotic region, the dilatation balloon (18) forms a seal against the inner wall surface of the blood vessel to exclude blood in the vessel from contacting the stenotic region. The method preferably further includes cooling the blood circulating in the blood vessel about a shaft of the catheter with cooling fluid circulating within cooling lumens (70, 72) of the catheter and cooling an inner wall surface of the blood vessel in the stenotic region during the application of radiation to the medial cell layer. Finally, the method also preferably includes perfusing blood in the vessel through the catheter (250) across the stenotic region during dilatation of the stenotic region to maintain circulation of blood through the blood vessel during the dilatation of the stenotic region.

摘要： A device (28) for prostate treatment is inserted into a prostatic portion (10A) of an urethra (10) and connected to an energy source (37). Energy is delivered to the prostate (14) from the device (28). The amount of energy emitted to prostatic tissue adjacent to a bladder (12) is greater than that emitted to prostatic tissue distant from the bladder (12).
