Claim Text:
1. An intra-pericardial medical device (IPMD) comprising: a lead body having a proximal portion, a distal end portion, and an intermediate portion extending along a longitudinal axis between the proximal portion and the distal end portions; control logic connected to the intermediate portion of the lead body; an energy source connected to the lead body and electrically connected to the control logic; a stimulus conductor extending along the lead body and electrically connected to the control logic; an electrode provided on the lead body and electrically connected to the stimulus conductor, the electrode configured to deliver stimulus pulses; and a telemetry conductor provided within the lead body and positioned along the intermediate portion of the lead body, the telemetry conductor wound into a series of coil groups to form a plurality of annular, interconnected inductive loops for at least one of receiving or transmitting radio frequency (RF) energy that represents at least one of recharge power or communications signals, wherein at least two of the coil groups includes a number of coil windings wound about a lateral axis of the intermediate portion and stacked co-axially above one another along the lateral axis, the lateral axis extending in a direction transverse to the longitudinal axis of the intermediate portion, the coil groups being connected to one another in series and be distributed apart from one another within and along the lead body forming the plurality of annular interconnected inductive loops.
