Implantable Medical Device with Implantation Detection and Staged Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable medical devices require complex and costly procedures for activating medically sensitive functions, often necessitating the presence of additional personnel and non-sterile programming devices during implantation.
Innovation Solution
Implantable medical devices are designed with a processor and memory unit that automatically activate diagnostic or therapeutic functions after detecting implantation and fulfilling predefined time criteria or function tests, eliminating the need for additional programming devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medically sensitive functions are manually activated during implantation using programming devices, then activation control is achieved, but device complexity and personnel requirements increase
Solution Approach 1:
The implantable medical device automatically detects its own implanted state and activates therapeutic functions without requiring external programming devices or additional personnel, making the system self-sufficient for activation
Solution Approach 2:
The device performs preliminary detection of implantation conditions (such as impedance measurements or temperature sensing) before automatically activating therapeutic functions, ensuring proper activation without manual intervention
2Reliability
If all therapeutic functions are activated simultaneously upon implantation detection, then treatment coverage is maximized, but energy consumption increases
Solution Approach 1:
The device performs preliminary detection and evaluation of implantation conditions before activating therapeutic functions, allowing selective activation based on detected parameters rather than simultaneous activation of all functions
Solution Approach 2:
The activation state of therapeutic functions is made dynamic and adjustable based on detected implantation conditions, allowing the device to adapt which functions are activated rather than using a fixed simultaneous activation scheme
3Productivity
If therapeutic functions are activated immediately upon implantation, then treatment starts promptly, but malfunction risks during transport increase
Solution Approach 1:
The device performs preliminary detection of implantation status (such as detecting body temperature, impedance, or other physiological parameters) before activating therapeutic functions, ensuring activation only occurs when properly implanted rather than immediately upon power-up

AI summary
The invention relates to an implantable medical device which performs the following steps during operation: a) performing a detection (210) of whether the implantable medical device (100) is in an implanted state; b) if it is detected that the implantable medical device (100) is in an implanted state (220), activating a first diagnostic or therapeutic function (230) of the implantable medical device (100), and subsequently activating a second diagnostic or therapeutic function (260) of the implantable medical device (100), wherein the second diagnostic or therapeutic function (260) is activated only after the fulfilment (250) of at least one activation criterion selected from the group consisting of an elapse of a first time period from the activation of the first diagnostic or therapeutic function (230), an elapse of a second time period from the detection (210) that the implantable medical device (100) is in an implanted state, and a passing of a function test.
