An intra-pericardial medical device is provided that comprises a lead body having a proximal portion, a distal end portion, and an intermediate portion extending between the proximal portion and the distal end portions. An intra-pericardial medical device further includes the control logic housed with the lead body and an energy source housed within the lead body. A stimulus conductor is included and extends along the lead body. An electrode is joined to the stimulus conduct near the distal end portion, where the electrode configured to deliver stimulus pulses. A telemetry conductor is provided within the lead and extends from the proximal portion and along the intermediate portion of the lead body. The telemetry conductor is wound into a series of coil groups to form inductive loops for at least one of receiving and transmitting radio frequency (RF) energy.
