Penile Prosthetic Insert Channel Preserves Vascularization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing penile prosthetics for erectile dysfunction often require significant dilation of healthy tissue, which can lead to reduced vascularization and less natural erections, as they lack a mechanism to maintain and utilize existing vascularized tissue effectively.
Innovation Solution
A penile prosthetic insert with a bio-compatible body featuring a channel that is more resistant to deformation, allowing it to maintain its structure in both flaccid and erect states, and is designed to be implanted with minimal dilation, preserving healthy tissue and facilitating better blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional penile prosthetics are implanted with significant dilation of healthy tissue, then the implant space is formed to receive the cylinder, but the vascularization of the tissue is reduced and the erection becomes less natural
Solution Approach 1:
The prosthetic device is divided into multiple functional segments: a cylindrical implant portion, a channel portion, and a positioning tool. The channel portion is specifically designed as a segmented structure that preserves vascularized tissue while accommodating the cylinder, allowing the implant space to be formed with minimal dilation of healthy tissue.
Solution Approach 2:
A positioning tool is introduced as an intermediary device during implantation. This tool is inserted through the channel portion to accurately position the cylinder within the corpora cavernosum, enabling precise placement without requiring extensive dilation of surrounding healthy tissue.
2Stability of the object's composition
If the channel is made more resistant to deformation, then the channel maintains its structure in both flaccid and erect states, but the surrounding body tissue must be appropriately designed to accommodate this
Solution Approach 1:
The channel portion is designed with locally enhanced resistance to deformation compared to the surrounding body tissue. This local quality differentiation allows the channel to maintain its structural integrity and preserve vascularized tissue during penis transitions between flaccid and erect states, while the surrounding body remains appropriately flexible.

AI summary
An implantable penile prosthetic insert (20) for placement in a corpora cavernosum of a penis and capable of transitioning the penis between a flaccid and an erect state. A body of the insert is made from a bio-compatible material and extends between a proximal end and a distal end. The body includes an exterior surface (28) defining a channel (30) extending longitudinally along the body. The body is configured to transition between a first state corresponding to the flaccid state of the penis and a second state corresponding to the erect state of the penis. The channel is present in both the first and the second state. A method for implanting a penile prosthetic insert and a kit of parts are also disclosed.
