Modular antitachyarrhythmia therapy system
First Claim
Patent Images
1. An implantable cardiac stimulus device for use in a patient having a heart, comprising:
- a housing containing sensing circuitry and therapy circuitry for providing cardiac stimulus, the housing adapted for coupling to a lead having at least one electrode thereon;
the implantable cardiac stimulus device being configured for implantation, sensing and therapy delivery from outside the heart, using a lead also implanted outside the heart;
wherein the implantable cardiac stimulus device is configured to communicate, using the patient'"'"'s body as a conductive medium for communication, with a physically separate first module adapted for implantation in the patient, and to receive data related to respiration from the first module.

Abstract
This document discusses, among other things, a modular antitachyarrhythmia therapy system. In an example, a modular antitachyarrhythmia system includes at least two separate modules that coordinate delivery an antitachyarrhythmia therapy, such as defibrillation therapy. In another example, a modular antitachyarrhythmia therapy system includes a sensing module, an analysis module, and a therapy module.
