Medical Implant Carrier with Piercing Protrusion for Tissue Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suturing devices are difficult to use for anchoring grafts and implants due to their small size and lack of configuration for needle-less sutures and tissue dilation, and they are not versatile for different types of sutures and implants.
Innovation Solution
A medical device with a carrier movably disposed within an elongate member, featuring a protrusion with a tip to pierce tissue and an engagement surface to secure implants, allowing for anchoring and movement limitation, suitable for various suture designs and implant types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If known suturing devices use thin filaments with needles, then suturing function is achieved, but the device becomes difficult and hazardous to use for anchoring grafts and implants
Solution Approach 1:
The device is divided into distinct functional segments: a carrier component that holds the implant, a protrusion with tip for tissue piercing, and an engagement surface for securing the implant. This segmentation allows each component to be optimized for its specific function while simplifying the overall operation for anchoring grafts and implants.
Solution Approach 2:
The carrier is configured to be movably disposed within the elongate member, allowing dynamic adjustment and positioning during the procedure. This mobility enables the device to adapt to different tissue depths and angles, improving ease of operation for various anchoring scenarios.
2Adaptability or versatility
If known suturing devices are designed for traditional sutures, then conventional suturing is effective, but the device cannot accommodate needle-less sutures, implant anchors, or tissue dilation
Solution Approach 1:
The device is designed as a universal platform that can accommodate multiple implant types including needle-less sutures, implant anchors, and grafts. The carrier and engagement surface are configured to work with various connecting portions, allowing a single device to perform multiple functions without requiring separate specialized tools for each implant type.
Solution Approach 2:
The device allows for parameter changes in terms of the implant connecting portions it can accommodate. By designing the engagement surface and carrier to work with different lumen sizes and shapes, the device can adapt to various implant configurations, expanding its versatility across different surgical applications.
3Measurement precision
If the protrusion tip is small for precise tissue piercing, then piercing precision is improved, but the device becomes more hazardous to use
Solution Approach 1:
The carrier acts as an intermediary between the actuator and the protrusion tip. It provides controlled movement and positioning of the tip, allowing precise tissue piercing while maintaining safety through controlled deployment. The carrier's movable disposition within the elongate member enables gradual advancement, reducing the risk of uncontrolled tissue damage.
Solution Approach 2:
The device allows for preliminary positioning and preparation before the actual tissue piercing action. The carrier can be positioned and the protrusion tip prepared in advance, allowing the surgeon to plan the precise insertion point and angle before committing to the piercing action, thereby improving both precision and safety.

AI summary
An apparatus includes a carrier configured to be movably disposed within a channel defined by an elongate member. The carrier includes a proximal end portion and a distal end portion. The proximal end portion is configured to be coupled to an actuator. The distal end portion includes a protrusion and an engagement surface. The protrusion has a tip configured to bodily pierce tissue. The protrusion is configured to be received within a lumen defined by a connecting portion of an implant, such as, for example, a pelvic floor implant, such that the tip extends through the lumen defined by the connecting portion of the implant. The engagement surface is configured to engage a portion of the connecting portion of the implant to limit movement of the connecting portion of the implant relative to the protrusion.
