Abstract
The invention relates to an improved penile erection device and improved method for implanting such devices into the corpus cavernosum of the penis. The invention further relates to tools for implanting the improved penile erection device. Furthermore, the invention relates to insertion tools that permit precise placement of conventional inflatable prostheses cylinders such that puncture or damage of the glans penis does not occur during placement.
Claims14
A device for implanting the distal tip of a penile implant prosthesis without puncturing the glans penis, said device comprising an elongated body having a handle portion at one end, an intermediate portion, and a tip portion that includes a hole at the opposing end to secure a suture, wherein said intermediate portion includes an outwardly angled shaft section and linear handle section, and wherein the linear handle section is aligned in spaced and parallel relation to the axis of the outwardly angled shaft section, and wherein said outwardly angled shaft section has a convexity sized to accommodate and partially surround said distal tip of said penile implant prosthesis along a length of said distal tip.
An improved penile prosthesis device comprising;
- a. at least one cylinder having a proximal portion and a distal portion implantable within a corpus cavemosum of the penis, said cylinder having a defined, tool-engaging cradle on the external surface of a distal tip of the distal portion;
- b. a fluid containing reservoir;
- c. a pump chamber attached to said reservoir chamber;
- d. a means coupled to said cylinder and said pump chamber for providing fluid communication between said cylinder and said pump chamber;
- and
- e. a means for controlling fluid communication between said reservoir chamber and said pump chamber;
- wherein said cradle allows the insertion of the distal tip of said penile prosthesis to be implanted into the glans penis without puncturing said glans penis.
A method of implanting a penile prosthesis device without puncturing the glans penis or the penile prosthesis, said method comprising the steps of:
- a. threading a suture through the opening located at the distal tip of an insertion tool having a shaft with an opening therein;
- b. securing said suture around the shaft opening so as to fasten the cylinder of said penile prosthesis to the distal tip of said insertion tool;
- c. positioning the distal tip of the prosthesis cylinder for implantation;
- and
- d. pulling the insertion tool and suture back out of the penis.
A method of implanting a penile prosthesis device, that includes a cylinder, without puncturing the glans penis or the penile prosthesis, said method comprising the steps of:
- a. threading a suture through the opening located at the distal lip of an insertion tool;
- b. securing said suture substantially about an external circumference of a distal end of said cylinder below a distal tip of said cylinder so as to secure the cylinder of said penile prosthesis to the distal tip of said insertion tool;
- c. positioning the distal tip of the prosthesis cylinder for implantation;
- and
- d. pulling the insertion tool and suture back out of the penis.
