Modular Neurostimulation Pulse Generator for Reusable Trialing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spinal cord stimulation therapies are not cost-effective due to the high expense of single-use trial simulators and the need for large devices to accommodate electrical connectors, which compromises patient comfort.
Innovation Solution
A reusable system for neurological stimulation that includes a pulse generator module and two lead interface modules, one for intraoperative testing and another for patient-worn trialing, allowing for efficient and compact spinal cord stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-use trial simulators are used for patient-worn trialing, then the reliability of therapy evaluation is improved, but the cost of treatment increases significantly
Solution Approach 1:
The external pulse generator is designed to serve multiple functions: it can be used for intraoperative testing and for patient-worn trialing. The device includes a reusable pulse generator module that can interface with different lead adapters, allowing the same generator to perform both testing and trial stimulation functions, thereby eliminating the need for separate single-use trial simulators and reducing overall treatment costs
2Reliability
If electrical connectors are included in trial simulators to ensure reliable lead connection, then the reliability of electrical connection is improved, but the device size increases
Solution Approach 1:
The system is divided into separate modular components: a reusable pulse generator module and detachable lead adapters. The electrical connectors are integrated into the lead adapters rather than being part of a large single-use simulator, allowing the main generator to remain compact while still providing reliable electrical connections through the modular adapter interface
