Artificial Crus Penis Support for Penile Prosthetic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Penile implants designed for natal males are not well-suited for trans-males, as they lack the necessary anatomical support for adequate positioning and functionality, leading to issues with penetrative intercourse due to anatomical differences in the pelvis.
Innovation Solution
Development of a penile implant system with an artificial crus penis that replicates the suspensory ligaments of a natal male, providing a reinforced foundation for a penile prosthetic to be situated anatomically correctly and functionally suitable for penetrative intercourse, including a Y-shaped neophallus implant with a transfer joint to orient the prosthetic correctly and a single inflatable cavity for enhanced comfort and girth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a penile implant designed for natal males is attached directly to the anterior pelvis in a trans-male, then the implant can be placed, but the neopenis ends up in an anatomically non-natural position (too far cephalad) and lacks adequate support for penetrative intercourse
Solution Approach 1:
The patent introduces an intermediary support structure (artificial crus penis or support device) between the pelvis and the penile implant. This intermediary component provides the necessary anatomical positioning and structural support, acting as a mediator that translates the simple anterior pelvic attachment into proper penile anatomy orientation and function.
2Adaptability or versatility
If a penile implant designed for natal males is used in a trans-male, then the implant structure can be utilized, but the implant lacks adequate support to allow for penetrative intercourse due to absence of corpora cavernosa, crus penis, and tunica
Solution Approach 1:
The patent segments the penile implant system into separate functional components: the standard penile implant (for erectile function) and a separate support structure (for anatomical positioning and structural integrity). This segmentation allows each component to be optimized independently - the implant for versatility and the support structure for reliability during intercourse.
3Ease of operation
If the proximal end of the penile prosthetic is positioned superior to the ridge in the receptacle, then the neophallus is in a flaccid state, but when positioned inferior to the ridge, the neopenis is maintained in an erect state which may not be comfortable for all situations
Solution Approach 1:
The patent implements a dynamic positioning mechanism where the penile prosthetic can be moved along the longitudinal axis of the receptacle. The ridge acts as a mechanical stop that provides stable positions (flaccid when superior, erect when inferior). This dynamic adjustability allows the user to switch between states as needed, with the ridge providing mechanical feedback and positioning stability.

AI summary
A device adapted to support an erection for a trans-male person identified as female at birth has an implantable support with a base including a first receptacle and a second receptacle. The receptacles are shaped and sized to receive an end portion of a penile prosthesis. When the base of the implantable support is attached to a pelvis of the trans-male person and the penile prostheses are inserted into the receptacles, the neophallus of the trans-male person, when erect, will be adapted for penetrative intercourse.
