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 can be cumbersome and prone to complications.
Innovation Solution
A subcutaneously implantable device with a clip that anchors to muscle, bone, or tissue and a prong extending to contact organs or nerves, connected via a wire to an external device for monitoring and therapeutic purposes, allowing for less invasive implantation and simplified electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional invasive surgery is used for implantation, then reliable electrical connection can be achieved, but surgical complexity and patient risk increase
Solution Approach 1:
The device is divided into separate functional components: a subcutaneous implantable device (SID) containing electrical circuitry and a lead with electrodes. This segmentation allows the complex electrical connection function to be distributed across multiple simpler components, reducing the complexity of the overall implantation procedure while maintaining reliable electrical connection through the wire connecting the SID to the external device
Solution Approach 2:
The lead system is extracted from the traditional invasive implantable device structure. Instead of having the entire device implanted with complex lead systems, only a simple lead with electrodes is implanted subcutaneously, while the main electrical circuitry and processing functions are extracted to a separate subcutaneous implantable device that connects via wire to the external device
2Adaptability or versatility
If complex lead systems are used, then effective monitoring and therapy can be provided, but device complexity and complication risk increase
Solution Approach 1:
The subcutaneous implantable device serves multiple functions: it acts as a signal receiver from the body, processes the signals for diagnostic purposes, and transmits electrical stimulation for therapeutic purposes. This multi-functionality is achieved in a single integrated device rather than requiring multiple separate lead systems, thereby reducing overall device complexity while maintaining comprehensive monitoring and therapy capabilities
Solution Approach 2:
The electrical circuitry, signal processing capabilities, and therapeutic delivery functions are merged into a single subcutaneous implantable device. This consolidation eliminates the need for multiple separate lead systems and complex wiring arrangements, reducing device complexity while providing effective monitoring and therapy through the integrated design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables less invasive implantation and reduced risk of complications by anchoring the device subcutaneously, providing effective monitoring and therapeutic electrical stimulation without the need for complex lead systems, improving patient outcomes and procedural efficiency.
Implementation Method 1
A wire conductively connected to the first electrode is configured to be connected to an external device that is positioned outside of a patient's body to electrically connect the subcutaneously implantable device to the external device

AI summary
A subcutaneously implantable device includes a clip that is configured to anchor the subcutaneously implantable device to a muscle, a bone, and/or a first tissue, and a first prong with a proximal end attached to the clip and a distal end extending away from the clip that is configured to contact an organ, a nerve, and/or a second tissue. A first electrode on the first prong is configured to contact the organ, the nerve, and/or the second tissue. A wire conductively connected to the first electrode is configured to be connected to an external device that is positioned outside of a patient's body to electrically connect the subcutaneously implantable device to the external device.
