US Patent:

20090275998, Nov 5, 2009

Filed:

Apr 29, 2009

Appl. No.:

12/432502

Inventors:

John E. Burnes - Coon Rapids MN, US
Becky Lynn Dolan - Chisago City MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/365
A61N 1/39

US Classification:

607 4, 607 17

Abstract:

According to this disclosure, a non-transvenous pacing and, optionally defibrillation, therapy device is implanted subcutaneously and oriented to provide cardiac sensing from electrodes spaced from a heart and deliver pacing and/or defibrillation from one or more non-transvenous electrodes (e.g., an epicardial or pericardial electrode or electrode patch). A subject receiving a device according to this disclosure is monitored to confirm a relatively stable bundle branch block (i.e., delayed activation) of one ventricle. The subcutaneous device has electrodes disposed on the housing and/or having an electrode on a subcutaneous medical lead is oriented so that the pacing (and sensing) vector impinges mainly upon the one ventricle, and/or optionally an epicardial or pericardial lead is deployed to a last-to-depolarize ventricle (e.g., a left ventricle) so that single-ventricular pacing is delivered to achieve fusion depolarization of both ventricles.
