Implantable Infusion Needle System for Erectile Dysfunction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for inducing penis erection, such as injecting medicaments like papaverine or prostaglandin E1 into the corpora cavernosa, are inconvenient and require manual skill, with potential for improper administration and dosing, and existing implantable infusion devices are not designed for simultaneous injection at multiple sites.
Innovation Solution
A system with permanently implanted, long, flexibly bendable infusion needles that can penetrate self-sealing housings adjacent to the corpora cavernosa or deep arteries, allowing for simultaneous or rapid sequential injection at multiple sites, reducing the need for manual piercing and ensuring accurate drug delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual injection of medicament into corpora cavernosa is performed, then the patient can achieve penis erection, but the procedure is inconvenient and requires manual skill with potential for improper administration
Solution Approach 1:
The infusion needle is pre-implanted in the patient's body at the appropriate location adjacent to the corpora cavernosa or deep arteries, eliminating the need for manual piercing during each injection. The needle is positioned in advance to ensure accurate drug delivery location, and the housing is pre-positioned to maintain proper anatomical placement.
Solution Approach 2:
The permanently implanted infusion needle system allows the patient to self-administer medication without requiring manual injection skills. The patient simply needs to connect the syringe to the external connection element of the housing, and the pre-positioned needle automatically ensures proper delivery location, making the procedure self-service oriented and eliminating the need for medical professional assistance.
2Ease of operation
If medicament is injected manually from outside the penis, then the patient can receive treatment, but the patient must pierce himself with the infusion needle which is not an easy task
Solution Approach 1:
The infusion needle and housing are implanted in advance during a surgical procedure, positioning the needle tip adjacent to the corpora cavernosa or deep arteries. This preliminary action eliminates the need for the patient to perform needle insertion themselves, as the needle is already in place and ready for medication delivery.
Solution Approach 2:
The permanently implanted housing acts as an intermediary between the external syringe and the internal infusion needle. The housing contains the connection element that interfaces with the syringe externally, while the infusion needle is positioned internally adjacent to the target tissue, mediating the connection between external administration and internal delivery.
3Productivity
If existing implantable infusion devices are used, then the device is implanted inside the patient's body, but they are not designed for simultaneous injection at multiple sites
Solution Approach 1:
The housing is divided into multiple penetration areas, with each penetration area containing an infusion needle tip positioned adjacent to different corpora cavernosa or deep arteries. This segmentation allows simultaneous or sequential injection at multiple sites through a single implanted device, enabling treatment of both sides of the penis without requiring multiple separate implants.
Solution Approach 2:
The single implanted housing and infusion needle system is designed to perform multiple injection functions simultaneously. The housing can deliver medication to both the left and right corpora cavernosa or to multiple deep arteries through its multiple penetration areas, making the device universal for treating bilateral erectile dysfunction without requiring separate devices for each side.

AI summary
A penis erection stimulation system comprises one or more infusion needles, the tip ends of which are disposed within and implanted along with at least one first housing adjacent the patient's left and right corpora cavernosa. The respective other end or ends of the infusion needles are disposed and implanted along with at least one second housing remote from the first housing. A reservoir and a pump are also implanted inside the patient's body to supply the infusion needle with infusion liquid. A drive unit also adapted for implantation inside the patient's body is arranged for advancing and retracting the infusion needle such that its tip end penetrates the at least one first housing's outer wall at least in two different penetration areas either simultaneously or in immediate time succession, thereby injecting drugs into the patient's body for stimulating penis erection.
