  • Patent number: 11925376
    Abstract: 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.

  • Patent number: 11717430
    Abstract: A stent delivery system includes a shaft extending from a proximal end of the system into a delivery tip at a distal end. The shaft includes a coil and a stent bed. A stent is loaded onto the stent bed and has a first portion at its distal end having a greater flexibility than a second portion at its proximal end. Sheathing is movable over the stent bed between pre-deployed and deployed positions. The sheathing includes a flexible section at the sheathing distal end, a semi-flexible section adjacent the flexible section, and a stiff section adjacent the semi-flexible section. The delivery tip is more flexible than the combination of the stent bed, the first portion of the stent, and the flexible section of the sheathing, which is more flexible than the combination of the stent bed, the second portion the stent, and the flexible section of the sheathing.
