Deflection Member Guiding Curved Needle for Pelvic Implant Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical insertion tools for implants in the pelvic region often cause tissue damage and are uncontrollable, leading to complications such as nerve or organ punctures due to their large size and inappropriate curvature.
Innovation Solution
A deflection member with a fixed curvature and a groove is used to guide an elongate member, allowing for precise placement of implants within the pelvic region by deflecting the piercing portion along the curvature, reducing tissue trauma and improving control during insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional insertion tools with large needles are used to deliver implants, then the implant can be delivered to the pelvic region, but tissue trauma and damage to adjacent nerves or organs increases
Solution Approach 1:
The patent changes the physical parameters of the insertion tool by using a curved needle instead of a straight large needle. The curved geometry allows the needle to follow a predetermined path that avoids critical structures, thereby delivering the implant while minimizing tissue trauma and damage to adjacent nerves or organs.
Solution Approach 2:
The insertion tool incorporates a curved portion with a specific radius of curvature that matches the anatomical path to the implant site. This curvature enables the needle to navigate around sensitive structures in the pelvic region, reducing harmful effects while maintaining delivery capability.
2Device complexity
If traditional straight insertion tools are used, then the structure is simple, but the tool deviates from the desired direction and causes complications
Solution Approach 1:
The insertion tool is designed with a curved portion having a predetermined radius of curvature that matches the anatomical path to the implant site. This curvature provides directional control, preventing deviation from the desired insertion path and avoiding complications while maintaining relatively simple device structure.
3Ease of operation
If insertion tools with inappropriate curvature are used, then the tool can be inserted, but the implant cannot be delivered to the desired location
Solution Approach 1:
The curved portion of the insertion tool has a predetermined radius of curvature specifically designed to match the anatomical path to the implant site. This ensures that when the tool is inserted, it naturally follows the correct trajectory, delivering the implant precisely to the desired location in the pelvic region.

AI summary
In one general aspect, an apparatus can include an elongate member configured to be associated with an implant and having a piercing portion. The apparatus can include a deflection member having a fixed curvature disposed within a plane. The deflection member can have a distal end configured to be disposed within a body of a patient. The deflection member can define a groove extending along at least a portion of the deflection member. The groove of the deflection member can be configured to deflect the piercing portion of the elongate member.
