COMMUNICATION BETWEEN A MEDICAL DEVICE AND A LEAD-BORNE DEVICE
First Claim
Patent Images
1. An implantable medical lead comprising:
- a lead body comprising a proximal end coupled to a medical device and a distal end;
a lead-borne device coupled to the implantable medical device by at least two conductors within the lead body, wherein the lead-borne device selectively places either a first impedance associated with a first binary value or a second impedance associated with a second binary value across the at least two conductors and thereby communicates with the medical device.

Abstract
In general, the disclosure describes techniques for communication between at least one lead-borne device of an implantable lead and a medical device to which the lead is connected. The lead-borne device communicates with the medical device by modulating an impedance. The lead-borne device may communicate one or more bits of data to the medical device by selectively presenting either a first impedance or a second impedance to the medical device during one or more bit windows. The first and second impedance values may be respectively associated with first and second binary values, e.g., a high or one and low or zero.
