Sutureless Penile Prosthesis Cap With Converging Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing implantation procedures for penile prostheses cause bleeding and discomfort due to the formation of lesions in the glans penis during the insertion of needles and sutures.
Innovation Solution
A sutureless penile prosthesis assembly with a cap featuring converging slots and a tool with converging distal ends that engage with the cap to facilitate the insertion of the prosthesis into the corpora cavernosa without passing a needle or suture through the glans penis, using a spring forceps mechanism to guide the prosthesis into place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a needle and suture are used to guide the prosthesis through the glans penis, then the prosthesis can be positioned correctly, but lesions are formed causing bleeding and discomfort
Solution Approach 1:
The invention removes the needle and suture components from the implantation procedure. Instead of using a needle to pass a suture through the glans penis, the cap with slots provides a sutureless mechanism for guiding and positioning the prosthesis, thereby eliminating the harmful lesions while maintaining positioning accuracy
Solution Approach 2:
The cap with slots serves as an intermediary device between the implantation tool and the prosthesis. The slots in the cap guide the converging distal ends of the tool to properly position the prosthesis without requiring direct needle penetration through the glans penis, thus achieving accurate positioning without harmful lesions
2Ease of operation
If a suture is passed through the glans penis to pull the cylinder distally, then the prosthesis can be implanted, but a lesion is formed in the glans penis
Solution Approach 1:
The invention extracts the suture and needle from the implantation process by using a cap with slots that mechanically guides the prosthesis. The converging distal ends of the tool engage with the slots to pull and position the prosthesis without requiring suture passage through the glans penis, eliminating the lesion while maintaining ease of operation
Solution Approach 2:
The cap with slots performs the guiding and positioning function that previously required a needle and suture. The slots themselves provide the mechanical interface for the tool to engage and manipulate the prosthesis, making the system self-sufficient without harmful penetrating components

AI summary
A cap configured to be attached to a cylinder of an implantable penile prosthesis includes a body section and a tip section. The body section defines a recess that is attachable to an end of the cylinder of the implantable penile prosthesis and the tip section terminates in a tip having a curved exterior surface. The tip section defines at least one slot formed therein that extends away from the body section and has a slot axis that intersects with a longitudinal axis of the cap.
