摘要： Apparatus and methods are described for treatment of a urethra that is constricted due to benign prostatic hyperplasia (BPH). A positioning device is used to determine a location of the area of the urethra that is constricted and is to be treated. An execution device includes a dilation balloon, a cutter, an implant carrier, and an implant, the implant and the implant carrier both being disposed outside the outer surface of the dilation balloon. The urethra is dilated by expanding the dilation balloon, and a cut is formed in the inner surface of the urethra using the cutter. The implant is released into the cut within the inner surface of the urethra subsequent to the cutter forming the cut in the inner surface of the urethra, to thereby maintain the urethra in a dilated state. Other embodiments are also described.
