Sutureless Penile Prosthesis Cap with Converging Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional penile prosthesis implantation methods cause bleeding and discomfort due to the need to puncture the glans penis with a needle, which is avoided in the proposed sutureless approach.
Innovation Solution
A cap with converging slots on a penile prosthesis cylinder and a tool with converging distal ends that engage the slots, allowing the prosthesis to be inserted into the corpora cavernosa without using sutures or needles, facilitating a sutureless implantation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a needle is used to puncture the glans penis to guide the prosthesis, then the prosthesis can be accurately positioned, but it causes lesions and bleeding
Solution Approach 1:
The patent removes the needle and suture from the implantation process entirely. Instead of using a needle to puncture the glans penis, the invention uses a cap with slots that engages with a tool, allowing the prosthesis to be pulled through the corpora cavernosa without penetrating the glans tissue, thereby eliminating lesions and bleeding while maintaining positioning accuracy
Solution Approach 2:
The cap serves as an intermediary component between the prosthesis cylinder and the tool. The cap with its slots engages the tool's distal ends, creating a mechanical connection that allows force transmission to pull the prosthesis into position without requiring direct needle penetration of the glans penis
2Ease of operation
If a traction suture and needle are used for implantation, then the prosthesis can be pulled to the distal location, but the procedure becomes more complex and painful
Solution Approach 1:
The patent eliminates the suture and needle components from the implantation system. The cap with slots directly engages the tool, creating a simpler, sutureless implantation process that reduces both device complexity and procedural pain while maintaining the ability to pull the prosthesis to the correct distal location
Solution Approach 2:
The cap is designed with specific local features - slots positioned and oriented in a particular pattern - that enable selective engagement with the tool's distal ends. This localized geometric design provides the necessary mechanical interface without requiring complex overall system design

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.
