Injectable Subcutaneous Device Anchoring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional implantable medical devices, such as cardiac monitors and pacemakers, require invasive surgeries for implantation and have complex lead systems that complicate the process and increase risks.
Innovation Solution
A subcutaneously injectable device with a housing, guide, clip, and electrode that can be anchored to bone, muscle, or tissue using a surgical instrument, allowing for minimally invasive implantation and direct contact with organs or nerves for monitoring and therapeutic interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional invasive surgery is used for implantation, then reliable device placement can be achieved, but surgical complexity and risk increase
Solution Approach 1:
The device is divided into separate functional components: a housing containing circuitry, a lead with electrodes, and a clip for anchoring. This segmentation allows each component to be optimized independently and simplifies the implantation process by enabling minimally invasive delivery of the housing while the lead can be separately positioned.
Solution Approach 2:
A surgical instrument acts as an intermediary device to deliver the implantable medical device through a minimally invasive approach. The instrument includes a body and slider mechanism that facilitates the insertion and deployment of the device through a small incision, reducing surgical complexity while maintaining placement reliability.
2Adaptability or versatility
If complex lead systems are used, then comprehensive monitoring and therapeutic capabilities can be achieved, but implantation difficulty and risk increase
Solution Approach 1:
The lead system is segmented into multiple electrodes along its length, with each electrode capable of independent function. This allows comprehensive monitoring and therapeutic capabilities through a modular approach, where the lead can be delivered minimally invasively and then positioned to contact specific tissue targets.
Solution Approach 2:
The lead is designed with flexibility and adaptability to accommodate different anatomical positions and tissue contacts. The lead can be dynamically positioned during implantation to achieve optimal contact with organs or nerves, making the system versatile while maintaining ease of minimally invasive delivery.
3Strength
If traditional surgical implantation is used, then secure device anchoring can be achieved, but recovery time and patient risk increase
Solution Approach 1:
The anchoring function is extracted from the complex surgical implantation process and achieved through a dedicated clip mechanism. The clip can be deployed minimally invasively to secure the device to underlying tissue, separating the anchoring function from the delivery process and reducing patient risk and recovery time while maintaining anchoring strength.

AI summary
A method of subcutaneously injecting and anchoring a device to a bone, a muscle, and/or a tissue in a patient, the device having a clip configured to anchor the device to the bone, the muscle, or the tissue, includes making an incision in the patient. An instrument pre-loaded with the device is inserted through the incision. The instrument is advanced to the bone, the muscle, and/or the tissue upon which the device is to be anchored. A clip of the device is pushed onto the bone, the muscle, and/or the tissue using the instrument. The device is anchored to the bone, the muscle, and/or the tissue using the clip on the device.
