ACTIVE IMPLANTABLE MEDICAL DEVICE WITH CARDIAC LEAD AND PERIPHERAL LEAD DISCRIMINATION

摘要

The device includes a cardiac therapy circuit with a first terminal, and a peripheral therapy circuit with a second terminal. These terminals can either receive a cardiac detection/stimulation lead or a peripheral detection/stimulation lead of an organ. The device is configured to recognize the leads and automatically configure the connection terminals according to the type of lead received by the terminal. This includes discrimination methods for identifying the terminal on which a cardiac signal is detected, and selectively activating the cardiac therapy circuit and the peripheral therapy circuit based on the detection of the cardiac signal on a lead.

主权项

1. An active implantable medical device comprising:
a cardiac therapy circuit configured to generate stimulation, defibrillation and/or resynchronization pulses; a peripheral therapy circuit configured to generate peripheral stimulation pulses; first and second connection terminals, each adapted to receive either a first lead or a second lead, wherein the first connection terminal is coupled to the cardiac therapy circuit and the second connection terminal is coupled to the peripheral therapy circuit; wherein one of the leads is a cardiac detection/stimulation lead and the other is a peripheral detection/stimulation lead; a processor configured to verify a respective connection configuration of the leads to the first and second connection terminals and selectively activate or inhibit the cardiac and peripheral therapy circuits by:
collecting a signal on the first connection terminal;analyzing the signal to detect whether a cardiac signal is present;selectively activating the cardiac therapy circuit and peripheral therapy circuit when the presence of the cardiac signal is detected on the first connection terminal; andselectively inhibiting the cardiac therapy circuit and peripheral therapy circuit when the presence of a cardiac signal is not detected on the first connection terminal.
