Pelvic Mesh Implant with Rotatable Sheath Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for treating pelvic conditions such as urinary incontinence and pelvic organ prolapse are often invasive and time-consuming, necessitating a minimally invasive yet effective solution for implantable mesh devices that can address muscle and ligament weakness.
Innovation Solution
The development of a pelvic mesh implant system featuring a needle delivery device with a rotatable sheath and anchors, allowing for precise deployment of mesh slings or implants in the pelvic region, utilizing a mesh material with extension arms and end anchors, and incorporating docking features for secure implantation and minimal tissue disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical methods are used to treat pelvic conditions, then effective treatment is achieved, but surgical time and tissue disruption increase
Solution Approach 1:
The implant is divided into modular components including a mesh body, separate anchors, and delivery devices. This segmentation allows for precise placement of individual components through minimally invasive procedures, reducing overall surgical time while maintaining treatment effectiveness through the coordinated assembly of modular elements.
Solution Approach 2:
A delivery device with a needle and sheath acts as an intermediary tool to facilitate the minimally invasive insertion of the implant. The delivery device enables precise navigation and deployment of the implant components through small incisions, reducing tissue disruption and surgical time compared to traditional open surgery.
2Reliability
If traditional surgical methods are used to treat pelvic conditions, then effective treatment is achieved, but tissue disruption increases
Solution Approach 1:
The delivery device serves as an intermediary that enables minimally invasive implant placement through small incisions and needle insertion. This approach significantly reduces tissue disruption compared to traditional open surgical methods, while the implant components remain effectively positioned to treat pelvic conditions.
Solution Approach 2:
The implant utilizes a mesh structure composed of thin, flexible elements that can be inserted through minimal tissue disruption. The mesh design allows for gradual integration with surrounding tissues while maintaining structural support, reducing the harmful effects of tissue disruption associated with traditional rigid implant placement methods.
3Ease of operation
If minimally invasive implant deployment is used, then tissue disruption and surgical time are reduced, but deployment precision and reliability must be maintained
Solution Approach 1:
The delivery device with its needle and sheath components acts as a precision intermediary tool that enables minimally invasive deployment while maintaining accuracy. The device allows the surgeon to control the implant placement path and positioning with high precision through small incisions, ensuring that minimal tissue disruption occurs without compromising deployment accuracy.
Solution Approach 2:
The implant components are pre-assembled and pre-positioned on the delivery device before insertion. This preliminary arrangement ensures that when the device is inserted and deployed, the implant components are already in their correct relative positions, maintaining deployment precision while enabling minimally invasive placement through the delivery system's guided architecture.

AI summary
Various embodiments of sling or implant systems are provided. The sling or implant systems can be employed to treat incontinence, prolapse, and like conditions. A needle delivery device can be included, wherein the delivery device includes a needle and a rotatable sheath. The rotatable sheath can rotate upon actuation relative to the needle to selectively deploy or disengage an implant anchor from the distal end of the needle.
