A tool for removing non-visually, urinary tract stents placed within the urinary tract of a patient, comprising a distal end, a longitudinally-extending stem, and a handle. The distal end has a conical head with a groove for hooking a stent, stent string or similar stent configuration. The snare head may have a channel for advancing the tool through a urethra over a guide wire. The snare head has a narrow conical front end for dilating urethral strictures. The stem connects the snare head to the snare handle and is made to be flexible or bend on encountering resistance.

Stent removal snare and dilator

Urethrotome dilators for dilating a urethral stricture, and methods for forming and using the same are disclosed. In some embodiments, the urethrotome dilator includes a first distal end with a dilating head, a second proximal end with a handle, and a stem for connecting the first end to the second end. The dilating head may have a first region, a second region, and a channel for receiving a guidewire. The first region of the dilating head may have a substantially conical surface, with a vertex at its distal end and a base at its proximal end. The second region may have a substantially flat surface and a blade for stretching tissue. The blade may be integrally formed within the second region and may extend from the flat surface. The top edge of the blade may be tapered and blunt, while the two opposing sides of the blade may be formed with sharp corners for cutting tissue.

Urethrotome-dilator

A tool, for forming a cavity in a corpus cavernosa of a penis, includes a distal end (14), a longitudinally-extending cutting surface (16), and a main body portion (18). The cutting portion may be cylindrical or tapered, and may contain more than one longitudinally disposed cutting surface (24). The tool may be made from stainless steel, or may include plastic portions. A method using the invention includes the steps of making an incision in the side of the penis adjacent the corpus cavernosa, and inserting the distal end of the tool into the spongy tissue, to define a cavity. If fibrous or resistant tissue is encountered, the cutting portion is brought adjacent the region, and the tool either moved axially to cut the tissue, or rotated about its longitudinal axis (8) to cut or shave the tissue. Multiple tools of a kit of tools may be sequentially inserted to expand the cavity to the desired dimension. When the cavity is completed, the object, which may be an expansible or inflatable chamber, is inserted into the cavity.

Surgical penile dilator instrument and method for its use

A penile prosthesis includes a rotary pump for pressurizing a bag or chamber within the penis. The rotary pump includes a magnetically active rotor which, in one embodiment, is located within the penis, which can be made to spin by a rotary magnetic field generator. The rotary magnetic field generator may be similar to those used in conjunction with brushless DC motors, or it may be a permanent magnet spun about an axis. In operation of one embodiment, the magnetic field generator surrounds the penis at a location near the rotor. The rotor drives an impeller or blades which pressurize fluid from a reservoir, and tends to pressurize the bag or chamber to thereby render the penis rigid. A valve arrangement prevents loss of pressure when the rotating field is removed. In one embodiment, the valve arrangement includes a spring-operated check valve in conjunction with another valve, and in another embodiment, a single centrifugally-operated valve performs the same function. Other embodiments locate the rotary pump under the skin in the retropubic region or the scrotum, at locations at which a rotary magnetic field generator can rotate the pump rotor.
