Abstract
Devices, systems, and methods for remotely monitoring physiologic cardiovascular data are disclosed. At least some of the embodiments disclosed herein provide access to the external surface of the heart through the pericardial space for the delivery of the sensor to the epicardial surface of the heart. In addition, various disclosed embodiments provide for a memory device capable of receiving the physiologic cardiovascular data collected by the sensors and transmitting such data wirelessly to a remote location.
