Further Acute Research of a Subcutaneous Implantable Defibrillator (S-ICD) System

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Boston Scientific Corporation
ClinicalTrials.gov Identifier:
NCT00399217
First received: November 10, 2006
Last updated: February 14, 2017
Last verified: May 2010
  Purpose
The purpose is to further evaluate the operation, safety, and feasibility of a subcutaneous implantable defibrillator (S-ICD) system in patients who require an implantable cardioverter defibrillator (ICD)for treating ventricular tachyarrhythmias. The S-ICD electrode and pulse generator emulator will be briefly implanted and tested during the standard implantation procedure of an ICD, but then the S-ICD system will be removed entirely.

Condition Intervention
Ventricular Fibrillation Ventricular Tachycardia Device: Subcutaneous Implantable Defibrillator (S-ICD) system Device: ICD

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Acute Intra-operative Testing of Subcutaneous Implantable Defibrillator Emulator and Parasternal Electrode, Acutely Implanted, for Comparison With Transvenous System

Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Detailed Description:

The objectives of this study are to further evaluate the S-ICD system's ability to identify and terminate induced ventricular tachyarrhythmias in patients acutely with an S-ICD emulator and parasternal electrode during the implant procedure of a standard transvenous ICD.

The active emulator is not a powered medical device and all elements of the test system are removed following the testing.

This acute intra-operative protocol will test the ability of the electrode and emulator to appropriately convert the arrhythmia and allos an assessment of post shock pacing.
