Abstract
A method and system for recording changes to programmable parameters in an implantable pulse generator. An executable program is stored in an implantable pulse generator. A parameter log is maintained in the implantable pulse generator, where the parameter log is used to record changes to the state of one or more programmable parameters of the executable program. When a change is detected in the state, from a first state to a second state, of the one or more programmable parameters the first state of the one or more programmable parameters changed to the second state are recorded in the parameter log. The parameter log is retrievable to allow for analysis of when and how changes took place to the executable program.
Claims20
A method, comprising:
- storing an executable program in an implantable pulse generator, wherein the implantable pulse generator includes a parameter log and the executable program includes one or more programmable parameters having a first state;
- establishing a communication link between the implantable pulse generator and a medical device programmer;
- transmitting a first signal from the medical device programmer to change the first state of the one or more programmable parameters to the second state;
- receiving the first signal to change the first state of the one or more programmable parameters to the second state;
- detecting the change in the first state of the one or more programmable parameters to the second state;
- and
- storing in the parameter log the first state of the one or more programmable parameters changed to the second state.
A system including an implantable pulse generator and medical device programmer, the implantable pulse generator including:
- a memory circuit to store a parameter log and an executable program, wherein the executable program includes one or more programmable parameters having a first state;
- a parameter analysis circuit coupled to the memory circuit, wherein the parameter analysis circuit analyzes the first state of the one or more programmable parameters to detect a change in the first state to a second state of the one or more programmable parameters;
- a microprocessor coupled to the memory circuit and the parameter analysis circuit, wherein the microprocessor stores the first state of the one or more programmable parameters changed to the second state in the parameter log;
- and
- a communication circuit coupled to the microprocessor, wherein the communication circuit establishes a communication link between the implantable pulse generator and the medical device programmer, and the medical device programmer transmits a first signal, the communication circuit receives the first signal and in response to the first signal the first state of the one or more programmable parameters is changed to the second state.
