  • Cardiac pacing energy enhancement
    Patent number: 9844665
    Abstract: Example implantable cardiac stimulation devices, pulse generators, and methods providing enhanced cardiac pacing energy are disclosed herein. In an example, an implantable cardiac stimulation device may include a pulse generator having a pacing output node providing cardiac pacing pulses to be applied to a heart of a patient. The pulse generator may include a pulse voltage regulator that receives a pacing signal and generates cardiac pacing pulses at an output of the pulse voltage regulator according to the pacing signal. The pulse voltage regulator may receive a supply voltage to generate cardiac pacing pulses at the supply voltage, gated by the pacing signal.
    Type: Grant

  • Systems and methods for fast discharge in pacing circuits during RF interference
    Patent number: 9616240
    Abstract: The present disclosure provides a cardiac pacing system. The cardiac pacing system includes a right atrial ring electrode, a right atrial tip electrode, a right ventricle ring electrode, and a pacing integrated circuit (IC) including a first pace output node electrically coupled to the right atrial ring electrode, a pace return node electrically coupled to the right atrial tip electrode, and a second pace output node electrically coupled to the right ventricle ring electrode, wherein the pacing IC has a fast discharge configuration that facilitates reducing or eliminating a DC rectification current generated from RF interference during a fast discharge phase.
