Implanted Infusion Needle with Actuated Flap for Drug Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for inducing penis erection, such as injecting medicaments into the corpora cavernosa or using the Muse method, are inconvenient and require precise administration to ensure effectiveness, with potential for improper dosing and discomfort.
Innovation Solution
A system with permanently implanted infusion needles allows for convenient and precise injection of substances into the corpus cavernosum and deep arteries, using a housing with a penetration area and a drive unit to advance and retract the needle, ensuring proper drug delivery and minimizing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual injection of medicament into corpora cavernosa is used, then the penis can become turgid, but the procedure is inconvenient and requires precise administration technique
Solution Approach 1:
The infusion needle is permanently implanted in the patient's body in advance, positioned at the optimal location for drug delivery. This preliminary action eliminates the need for repeated manual injection procedures, as the needle is already in place and ready for use whenever treatment is needed.
Solution Approach 2:
The permanently implanted infusion needle acts as an intermediary device between the external drug delivery system and the internal corpora cavernosa. It provides a stable, pre-positioned pathway for medicament administration, eliminating the need for repeated manual piercing and positioning operations.
2Stability of the object's composition
If medicament is administered as a dry substance requiring mixing, then stability is maintained, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The medicament is prepared and loaded into the infusion system in advance during the implantation procedure. This preliminary preparation eliminates the need for patients to perform mixing operations at the time of administration, reducing both complexity and potential for error.
3Reliability
If injection location is not precisely controlled, then medicament may be transported to wrong body regions, but achieving precise control requires complex positioning procedures
Solution Approach 1:
The infusion needle is implanted at the precisely correct anatomical location during the initial surgical procedure. This preliminary positioning ensures that all subsequent drug deliveries occur at the optimal site without requiring complex real-time positioning systems or procedures.
Solution Approach 2:
The permanently implanted needle serves itself by maintaining its optimal position automatically through its fixed implantation. The system eliminates the need for external positioning mechanisms, as the needle's location is self-determined by its surgical placement and remains stable for long-term use.

AI summary
A penis erection stimulation system comprises one or more infusion needles disposed within and implanted along with one or more housings adjacent the patient's left and right corpora cavernosa. 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 tip end of the infusion needle such that it penetrates the housing in at least one penetration area, preferably at least in two different penetration areas either simultaneously or in immediate time succession, thereby injecting drugs along with the infusion liquid into the patient's body for stimulating penis erection. The outer wall of the housing accommodating the infusion needle comprises at least one door in the penetration area or areas. A drive is connected to the door for actively opening the door so as to allow for the infusion needle to be advanced through the opened door. The door may comprise a flap, such as a resilient, normally closed flap. It is particularly preferred if the drive connected to the door forms part of the drive unit coupled to the infusion needle. More specifically, the arrangement may be such that advancement of the infusion needle by means of the drive unit simultaneously causes the drive to open the door.
