Plastically Deformable Penile Remodeling Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for correcting penile curvature in Peyronie's disease are time-consuming and uncomfortable for surgeons, leading to potential fatigue and less-than-desired remodeling results, as they require prolonged application of counteracting forces to straighten the penis.
Innovation Solution
A cylindrical remodeling device with a plastically deformable member, coated with elastic fabric, that snugly grips the penis and can be bent into a shape to apply counteracting force, allowing for iterative adjustments to achieve desired straightening, optionally using inflatable linings for enhanced correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If surgeons manually apply counteracting forces to straighten the penis during surgery, then penile curvature correction is achieved, but surgeon fatigue and discomfort increase significantly
Solution Approach 1:
A cylindrical modeling device made of plastically deformable material serves as an intermediary between the surgeon and the penis. The surgeon shapes the cylinder to counteract the curvature, and this shaped cylinder is then applied to the penis to maintain the corrective force, eliminating the need for the surgeon to continuously apply manual pressure.
Solution Approach 2:
The corrective force is prepared in advance by shaping the plastically deformable cylinder to the desired configuration before application. Once shaped and applied, the device maintains the corrective position without requiring continuous surgeon intervention, allowing the surgeon to complete other surgical tasks.
2Manufacturing precision
If surgeons hold the desired position for extended periods to achieve remodeling, then penile straightening is achieved, but surgeon fatigue and pain increase
Solution Approach 1:
The plastically deformable cylindrical device acts as a mediator that retains the applied force indefinitely. Once the surgeon shapes the cylinder to the correct configuration, it maintains that shape and applies continuous corrective pressure without requiring the surgeon to hold the position.
Solution Approach 2:
The modeling device is self-maintaining in its corrective function. The plastically deformable material retains the imprinted shape and applies force autonomously, freeing the surgeon from the task of maintaining pressure and allowing them to perform other surgical procedures.
3Manufacturing precision
If manual penile modeling is performed during surgery, then curvature correction is achieved, but the process is time-consuming
Solution Approach 1:
The corrective configuration is prepared in advance by shaping the cylinder before surgery or during a brief preoperative period. This eliminates the need for time-consuming manual manipulation during the actual surgical procedure, as the device is already configured to counteract the specific curvature.
Solution Approach 2:
The pre-shaped cylindrical device serves as an intermediary that delivers the corrective force without requiring continuous surgeon manipulation. Once applied, it maintains the correction independently, allowing the surgical team to focus on other aspects of the procedure and improving overall surgical efficiency.

AI summary
A device for remodeling a penis, comprising a generally cylindrical hollow assembly having a lumen extending between proximal and distal ends, the distal end being in communication with the lumen to facilitate insertion of the penis into the lumen, the generally cylindrical structure having an interior surface facing the lumen and an exterior surface facing away from the lumen, a longitudinal direction and a transverse direction, the transverse direction being orthogonal to the longitudinal direction, the generally cylindrical assembly adapted to snugly and resiliently grip the penis, and includes an elastic fabric with one or more regions reinforced with a plastically deformable member.
