Subcutaneous Electrode Contact With Clip Anchoring for Tissue Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable medical devices, such as cardiac monitors and pacemakers, require invasive surgeries for implantation and lack efficient anchoring mechanisms for subcutaneous placement.
Innovation Solution
A subcutaneous device with a housing, clip, and prong configuration that allows for anchoring to muscle, bone, or tissue, featuring electrodes for monitoring and therapeutic capabilities, enabling minimally invasive implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional invasive surgery is used for implantation, then reliable device placement is achieved, but surgical complexity and patient discomfort increase
Solution Approach 1:
The device is divided into separate functional components: a housing containing circuitry, a clip for anchoring to bone or muscle, and a prong with electrode for tissue contact. This segmentation allows each component to be optimized for its specific function while simplifying the overall implantation process compared to traditional lead-based systems.
Solution Approach 2:
The clip acts as an intermediary element between the housing and the target tissue, providing secure anchoring to bone or muscle without requiring invasive surgical procedures. This intermediary mechanism enables reliable device placement through minimally invasive means.
2Reliability
If traditional lead-based system is used, then electrical signal transmission is achieved, but anchoring efficiency is insufficient
Solution Approach 1:
The electrode is merged with the prong structure, combining the electrical contact function with the anchoring function in a single integrated component. This eliminates the need for separate anchoring mechanisms and leads while maintaining reliable signal transmission through the integrated electrode-prong assembly.
3Stability of the object's composition
If invasive surgery is performed, then secure device fixation is achieved, but patient comfort and recovery are worsened
Solution Approach 1:
The clip is designed to self-anchor to bone or muscle through its mechanical structure, eliminating the need for surgical fixation procedures. The prong with electrode automatically engages with the target tissue, providing stable device fixation through the device's own structural features without requiring invasive surgical intervention or additional fixation materials.

AI summary
A subcutaneously implantable device includes a housing, a clip attached to the housing, a prong, and an electrode. The clip is configured to anchor the device to a muscle, a bone, and/or a first tissue. The prong has a base portion attached to the housing, an arm portion extending from the base portion so as to define a first plane that includes opposite ends of the arm portion of the prong and is perpendicular to a horizontal plane of the housing, and a contact portion that is configured to contact an organ, a nerve, the first tissue, and/or a second tissue. The contact portion is angled away from the first plane. The electrode is at the contact portion of the prong. The electrode is configured to contact the organ, the nerve, the first tissue, and/or a second tissue. Circuitry is in the housing.
