Implantable Medical Device Remote Access With Local Control Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and inefficiency of patient sessions for implantable medical devices (IMDs) due to the need for both clinicians and device representatives to be present during information retrieval, programming, and therapy provision, necessitating a more cost-effective and efficient interaction method.
Innovation Solution
A local user system at the clinic, controlled by a clinician, prioritizes local events over remote events from a remote user system, ensuring direct patient interaction and reducing the need for remote user travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both a clinician and a device representative are present during patient sessions for IMD information retrieval, programming, and therapy provision, then device operation assurance and patient care quality are improved, but session costs and operational complexity increase significantly
Solution Approach 1:
The system segments the roles and functions of device representatives and clinicians by providing separate remote access interfaces. The device representative can remotely perform programming and information retrieval tasks through a remote user system, while the clinician focuses on patient care at the local user system. This segmentation eliminates the need for both parties to be physically present simultaneously, reducing session complexity while maintaining device operation assurance through remote monitoring and intervention capabilities.
2Adaptability or versatility
If a remote user system is allowed to control the local user system without priority rules, then remote access capability is improved, but patient safety may be compromised due to conflicting control inputs
Solution Approach 1:
The system establishes priority rules in advance that automatically determine which control inputs to process. When a local event is detected, the system preemptively blocks remote events from being processed, and vice versa. This preliminary establishment of control hierarchy ensures that conflicting control inputs cannot simultaneously affect the IMD, thereby maintaining patient safety while preserving full remote access capability when no local user is present.

AI summary
One example of a system includes a local user system to interact with an implantable medical device and a local input device communicatively coupled to the local user system to generate local events. To operate the local user system, the local user system is to receive local events from the local input device and remote events from a remote user system communicatively coupled to the local user system via a medical device remote access system. The local user system is to process a local event and ignore a remote event in response to receiving a local event and a remote event simultaneously.
