Modular antitachyarrhythmia therapy system
First Claim
Patent Images
1. An implantable cardiac rhythm management system comprising:
- a first module configured for subcutaneous implantation and having a controller and communications circuitry; and
a second module configured for implantation in the heart of a patient, comprising a housing having first and second electrodes thereon and including communications circuitry for communicating with the first module and which is configured for attachment to cardiac tissue, the second module being entirely separate from the first module;
wherein the first module is configured to identify a tachyarrhythmia and direct the second module to deliver antitachyarrhythmia therapy;
wherein the first module is further configured to also deliver antitachyarrhythtnia therapy as needed; and
wherein the communications circuitry of each of the first and second modules is configured to use the body of the patient as a conductive medium for communication.

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 a defibrillation therapy. In another example, a modular antitachyarrhythmia therapy system includes a sensing module, an analysis module, and a therapy module.

9. A method of operating an implantable cardiac rhythm management system, the implantable cardiac rhythm management system including:
-
a first module implanted in a subcutaneous position of the patient and having a controller and communications circuitry, the first module being configured to deliver antitachyarrhythmia therapy as needed; and a second module configured for implantation in the heart of a patient, comprising a housing having first and second electrodes thereon and including communications circuitry for communicating with the first module and which is configured for attachment to cardiac tissue, the second module being entirely separate from the first module; the method comprising; the first module identifying a tachyarrhythmia; the first module directing the second module to deliver antitachyarrhythmia therapy including communicating via the body of the patient as a conductive medium for communication; and the second module delivering the antitachyarrhythmia therapy. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
