Title: Design and implementation of a low-power implantable cardiac monitoring device
Author: Shuhatovich, Lev Michael
Abstract: The conductance catheter technique is commonly used in research to assess cardiac hemodynamics through measurement of ventricular pressure and volume. In order to perform chronic cardiac studies in murine rodents, a small low-power device capable of performing these measurements is necessary. This thesis presents the design, implementation, and test of such a device, coupled with a radio that allows for the telemetry to be transmitted to a base station. Multiple low-power design techniques were employed in this device, which is surgically embedded in the animal. The total mass of the device with battery is 4 grams, and the device volume is 10cm3. Results show that it is capable of periodic monitoring of pressure volume loops for up to 60 days on a single charge.
