摘要： A urethral catheter having an adjustable dilating balloon length for dilating a prostatic urethra and a method for using same. The device includes a catheter to which a Foley balloon is affixed at the distal end, and to which a dilating balloon is annularly affixed, and includes means to independently expand and contract the balloons. Concentrically encompassing the catheter is a sheath or ring, which in one embodiment slides along the outside of the catheter. With the method of the present invention, the affected prostatic urethra is measured using a cystoscope and a calibrated catheter or other known measurement means. The sheath of an adjustable catheter of one embodiment of the present invention is set to the measured length by covering a portion of the dilating balloon with the sheath. The dilating catheter is inserted through the urethra until the balloon at the distal end is located within the bladder, at which point it is inflated and the dilating catheter is anchored in position. Then the dilating balloon is inflated to force the prostate away from the urethra. The dilating balloon may be left in place for periods of up to an hour or more to optimize the dilation effect, at which point the balloons are deflated and the dilating catheter is removed. With a further embodiment, the length of the dilating balloon is adjusted by severing portions of an adjustable length sheath to expose the length of balloon desired.

摘要： Disclosed is an apparatus and method for the treatment of the symptoms of obstructive prostatism. The apparatus comprises an expandable dilation catheter and preferably an axially elongate sheath, adapted for transurethral insertion via the external opening of the urethra. The sheath is ellipsoid in cross-section, and provides an initial path through which the catheter and a standard cystoscope lens is guided. The dilation catheter or the sheath are provided with a non-radiological locating means for positioning the dilation portion of the catheter with respect to an anatomical landmark. Once the catheter has been properly positioned with respect to both the bladder neck and the sphincter, the dilation balloon may be inflated to force open the affected prostatic urethra and eliminate the obstruction.
摘要翻译： 公开了一种治疗阻塞性前列腺症症状的装置和方法。 该装置包括可膨胀的扩张导管，优选地是轴向细长的护套，适于经由尿道的外部开口经尿道插入。 护套是椭圆形的横截面，并且提供了导管和标准的膀胱镜镜片被引导通过的初始路径。 扩张导管或护套设置有非放射性定位装置，用于相对于解剖学标记定位导管的扩张部分。 一旦导管已经相对于膀胱颈和括约肌适当地定位，则膨胀气球可以被充气以迫使打开受影响的前列腺尿道并消除阻塞。
