Pelvic Implant Anchor Delivery System for Secure Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices face challenges in securely attaching implants within the pelvic region of patients, particularly in treating female pelvic dysfunctions such as urinary incontinence and prolapse conditions, due to variations in implant size, shape, and fixation locations.
Innovation Solution
A medical device comprising a delivery tool with a carrier member and a cartridge that retains an anchor, allowing the anchor to be extended through the implant and bodily tissue, coupled to a catch, and then securely fixed, facilitating the securement of implants at various fixation points within the pelvic region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing implants and fixation methods are used, then pelvic floor repair can be performed, but it is difficult to securely attach implants at various fixation locations due to variations in implant size, shape, and material
Solution Approach 1:
The patent employs anchors with varying sizes, shapes, and configurations to adapt to different fixation locations and implant types. The delivery device is designed to accommodate multiple anchor parameters, allowing selection and deployment of appropriate anchors based on specific anatomical requirements and implant characteristics, thereby achieving reliable attachment despite variations in implant parameters
Solution Approach 2:
The fixation system is divided into separate components: the implant, multiple anchors, and a delivery device. This segmentation allows each component to be optimized independently - anchors can be designed with specific geometries for different tissue types, while the delivery device provides a standardized platform for deploying various anchor types, resolving the contradiction between reliability and adaptability
2Strength
If multiple anchors are used at various fixation points, then implant support is improved, but the complexity of delivering and placing anchors increases
Solution Approach 1:
The patent combines multiple anchors and the delivery device into an integrated system where anchors are pre-loaded into the delivery device in a standardized configuration. This merging reduces the complexity of the overall process by eliminating separate steps for anchor preparation and loading, while still enabling deployment of multiple anchors at different fixation points to provide strong implant support
Solution Approach 2:
The delivery device acts as an intermediary between the surgeon and the anchors, providing a standardized interface for anchor deployment. This intermediary simplifies the complex interaction between multiple anchors and varying anatomical sites by offering a controlled, repeatable delivery mechanism that handles the complexity of multi-anchor placement while maintaining strong fixation

AI summary
In one embodiment, a medical device includes a delivery tool having a carrier member, and a cartridge. The cartridge is coupled to the delivery tool. The cartridge defines an opening. The cartridge is configured to retain an anchor defining a lumen. The carrier member has a retracted configuration and an extended configuration. The carrier member is configured to extend through the lumen defined by the anchor and through the opening defined by the cartridge when the cartridge is coupled to the delivery tool and the carrier member is in its extended configuration.
