LEADLESS INTRA-CARDIAC MEDICAL DEVICE WITH BUILT-IN TELEMETRY SYSTEM
First Claim
1. A leadless intra-cardiac medical device (LIMD) configured to be implanted entirely within a heart of a patient, the IMD comprising:
- an intra-cardiac extension including a loop body having at least one loop segment retaining at least one coil group that is configured to one or both of receive and transmit radio frequency (RF) energy, wherein the loop body is configured to extend into a first chamber of the heart; and
a housing in electrical communication within the loop body, the housing comprising a transceiver, wherein the housing is configured to be securely attached to an interior wall portion of a second chamber of the heart, wherein the transceiver is configured to communicate with an external device through the RF energy.

Abstract
A leadless intra-cardiac medical device is configured to be implanted entirely within a heart of a patient. The device includes an intra-cardiac extension and a housing. The intra-cardiac extension includes a loop body having at least one loop segment retaining at least one coil group that is configured to one or both of receive and transmit radio frequency (RF) energy, wherein the loop body is configured to extend into a first chamber of the heart. The housing is in electrical communication within the loop body, and includes a transceiver, control logic and an energy source. The housing is configured to be securely attached to an interior wall portion of a second chamber of the heart, wherein the transceiver is configured to communicate with an external device through the RF energy.

12. A method of operating a leadless intra-cardiac medical device (LIMD) within a heart of a patient, the device including a loop body having at least one loop segment retaining at least one coil group within a first internal portion of the heart, and a housing connected to the loop body and secured within a second internal portion of the heart, wherein the method comprises:
-
emitting radio frequency (RF) energy from an external device to the IMD; generating an induced current in the loop body through the RF energy; passing the induced current from the loop body within the first internal portion of the heart to the housing secured within the second internal portion of the heart; and communicating between the LIMD and the external device through the generating and passing. - View Dependent Claims (13, 14, 15, 16, 17)
