Implantable Stimulation Nodes with Stored Profiles for Fast Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Implantable stimulation systems face challenges with limited bandwidth and data transfer rates due to hardware restrictions, necessitating efficient communication of large amounts of data during time-critical applications.
Innovation Solution
Incorporating memory and processing power at each implantable stimulation node to store and process stimulation profiles, allowing for reduced data transmission by using prestored profiles and indications, rather than full parameter sets, during time-critical therapy delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full stimulation parameter sets are transmitted during treatment phase, then complete therapy control is achieved, but communication bandwidth is exceeded and timing constraints are violated
Solution Approach 1:
Stimulation profiles are pre-configured and stored in the implantable stimulation node during a configuration phase before the treatment phase begins. This preliminary action allows the node to have ready-accessed parameter sets during time-critical treatment delivery, eliminating the need to transmit full parameter sets during therapy and thus resolving the bandwidth and timing constraints while maintaining complete therapy control.
2Reliability
If distributed implant approach with multiple contacts is used, then treatment targeting and reliability are improved, but data volume to be communicated increases
Solution Approach 1:
The system divides the implantable device into multiple independent stimulation nodes, each with its own processor and memory capable of storing and executing stimulation profiles locally. This segmentation allows each node to operate autonomously with pre-configured parameters, reducing the need for continuous centralized communication and thus decreasing the overall data volume transmitted while maintaining system reliability through distributed architecture.
3Productivity
If stimulation profiles are stored at each node, then data transmission is reduced, but device complexity increases
Solution Approach 1:
The implantable stimulation node is designed with universal components - a processor and memory - that serve multiple functions. The processor not only executes stimulation profiles but also manages local configuration and therapy delivery. The memory stores both configuration data and stimulation profiles. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while enabling profile storage and transmission reduction.

AI summary
Methods, systems, and devices for implantable node are described. The method may include storing, at an implantable stimulation node, a set of stimulation profiles in a memory during a configuration phase. The method may also include receiving a stimulation command corresponding to a stimulation profile of the set of stimulation profiles during a treatment phase. The method may further include delivering stimulation based at least in part on the stimulation profile corresponding to the received stimulation command. In some cases, the system may include an implantable hub, an implantable sensing node, and a sensing device.
