First Claim
Patent Images
1. A method of managing a cardiac rhythm in a medical patient, comprising:
- implanting a proximal housing in a location external to the patient'"'"'s heart wherein said proximal housing is configured to store energy;
implanting a distal module in the patient'"'"'s heart;
implanting a lead in the patient to couple said proximal housing and said distal module;
communicating a digital electrical transmission from the proximal housing external to the patient'"'"'s heart to the distal module inside the patient'"'"'s heart, wherein the digital electrical transmission comprises a digital power interval portion and a digital instruction interval portion, and wherein said communicating comprises transferring at least a portion of said stored energy from said proximal housing to said distal module via the digital power interval portion;
storing said transferred energy in said distal module; and
delivering at least a portion of the transferred energy in the distal module as one or more electrical pulses to the heart, thereby managing a cardiac rhythm in the patient.

Abstract
A cardiac rhythm management apparatus includes a proximal housing, a distal housing and a lead. The proximal housing includes a first energy storage device. The distal module is implantable within a patient'"'"'s heart, and includes a second energy storage device, at least one electrode, and a control module. The control module controls the delivery of at least one electrical stimulus from the second energy storage device to a location in communication with the patient'"'"'s heart. The lead connects the proximal housing to the distal module and is configured to communicate one or more digital signals between the proximal housing and the distal module.
