1. A leadless biostimulator comprising:
a housing; a plurality of electrodes formed integrally to the housing or coupled to the housing and separated by a maximum distance of 2 centimeters from the housing; a pulse generator hermetically contained within the housing and electrically coupled to the electrode plurality, the pulse generator configured to generate and deliver electrical pulses via the electrode plurality; a processor hermetically contained within the housing and communicatively coupled to the pulse generator and the electrode plurality, the processor being configured to control electrical pulse delivery according to programmed instructions; and a power supply hermetically contained within the housing and coupled to the pulse generator, the power supply configured to supply energy for operations and electrical pulse generation as a source internal to the housing, the power supply further comprising a primary battery that has a volume less than approximately 1 cubic centimeter and sources sufficient energy for supporting circuitry that consumes a maximum of 64 microwatts, wherein the pulse generator is further configured to selectively generate and deliver electrical energy in a stimulation pulse to at least two of the electrode plurality for causing a contraction of a patient's heart in response to control signals from the processor, the stimulation pulse being interrupted by at least one notch configured to convey information to a device external to the biostimulator. |
