Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require multiple external devices to communicate with different types of implantable medical devices (IMDs), as each IMD type follows a specific communication protocol, leading to inefficiencies and the need for multiple programmers or devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple external devices are used to communicate with different IMD types, then communication compatibility with various IMD types is improved, but device complexity and the number of devices required increases
Solution Approach 1:
The external telemetry device is designed with a reconfigurable RF transceiver circuit that can be dynamically configured to support multiple communication protocols and modulation types. This allows a single device to perform the functions of multiple specialized devices, enabling communication with different IMD types without requiring separate programmers for each protocol
Solution Approach 2:
The system employs dynamic reconfiguration of the RF transceiver circuit based on the detected IMD type. The modulation type and communication protocol are adjusted in real-time according to the specific IMD being communicated with, allowing the device to adapt its characteristics rather than maintaining fixed configurations
2Adaptability or versatility
If multiple external devices are used to communicate with different IMD types, then communication compatibility with various IMD types is improved, but system simplicity and ease of operation deteriorates
Solution Approach 1:
The external telemetry device integrates multiple communication capabilities into a single unified system. The device can automatically detect the IMD type and switch between different communication protocols and modulation types, providing a simplified user experience where one device handles all IMD types without requiring users to manage multiple specialized tools
3Device complexity
If a single external device is used to communicate with multiple IMD types, then device complexity is reduced, but communication compatibility with various IMD types deteriorates
Solution Approach 1:
The RF transceiver circuit parameters such as modulation type, frequency, and protocol are made changeable based on the target IMD. The system includes a modulation type selector that configures the transceiver to use appropriate modulation schemes (e.g., ASK, FSK, PSK) and communication protocols matched to the specific IMD type, enabling a single device to maintain compatibility across multiple device types through dynamic parameter adjustment

AI summary
A system including an external medical data telemetry device to communicate with an implantable medical device (IMD). The external medical data telemetry device includes a processor, a reconfigurable radio-frequency (RF) transceiver circuit, at least one far-field antenna, and a user interface. The reconfigurable RF transceiver circuit modulates an outgoing IMD data signal and demodulates an incoming IMD data signal using a modulation type that is selectable from a plurality of modulation types by the processor. The processor selects the modulation type using information entered by a user through the user interface.
