Removable Bladder Neck Implant With Plane Pressure Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implants for treating benign prostatic hyperplasia (BPH) are ineffective in treating an elevated bladder neck, as they cause tissue denaturation due to ischemic pressure, which is not suitable for constricted bladder necks.
Innovation Solution
A removable implant with a pressure means structure featuring a plane or flat surface, designed to exert localized but low surface pressure on the bladder neck, allowing for treatment without tissue denaturation, and optionally coated for targeted medication delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire structure implant with localized pressure is used to treat BPH, then tissue denaturation occurs due to ischemic pressure, but this approach is ineffective and potentially harmful for treating elevated bladder neck
Solution Approach 1:
The implant features a plane pressure means with a specific geometric shape (convex or concave surface) designed to distribute pressure locally across the bladder neck tissue. This local quality change transforms the pressure distribution from highly localized (causing ischemia) to broadly localized (achieving mechanical expansion without denaturation), enabling effective treatment of elevated bladder neck while avoiding tissue damage.
2Force
If high localized pressure is applied to expand the bladder neck, then the constriction can be counteracted, but tissue denaturation and damage occur
Solution Approach 1:
The plane pressure means introduces a dimensional change from point-like or line-like pressure application to area-based pressure distribution. By expanding the pressure application from a concentrated point to a two-dimensional plane with convex or concave surface, the implant achieves sufficient force to counteract bladder neck constriction while distributing the load to prevent tissue denaturation.
3Ease of operation
If the implant structure is simplified for easy insertion, then handling becomes easier, but the ability to provide even pressure distribution may be compromised
Solution Approach 1:
The plane pressure means incorporates convex or concave curved surfaces that naturally distribute pressure evenly across the contact area with the bladder neck tissue. This geometric curvature achieves uniform pressure distribution without complex mechanical structures, maintaining ease of insertion and retrieval while ensuring therapeutic pressure uniformity across the treatment area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The implant effectively treats bladder neck constriction by applying even pressure, reducing the risk of tissue damage while providing localized treatment and optional medication, ensuring precise and reliable intervention.
Implementation Method 1
The implant can exert a localized but large-area pressure on the tissue of the bladder neck by means of this plane pressure means
Implementation Method 2
Due to the special curvature of the surface, the fabric can lie particularly well in the pressure means structure, whereby a particularly advantageous pressure builds up. The use of the claimed implant is particularly efficient due to the even distribution of pressure.

AI summary
The invention creates an implant with which a bladder neck can be treated in a simple and reliable manner. This is achieved by an implant, in particular a removable implant, having a pressure means structure for expanding the bladder neck of a person. This pressure means structure exerts local pressure on the tissue of the bladder neck. The pressure means structure can be connected to a holding means for handling. This holding means, which may be a wire or a thread or a rod, can be used to insert the implant or the pressure means structure through the urethra into the bladder neck and, if necessary, to retrieve the pressure means structure from the patient's body after the end of the treatment.
