Method for implanting automatic implantable defibrillator
First Claim
Patent Images
1. A method for implanting an automatic defibrillator in a human and placing it proximate to the heart, comprising the steps of:
- passing a first catheter through the pericardial sac and into the intrapericardial space such that it terminates in a distal end positioned proximate to the heart;
inserting a first electrode having proximal and distal ends into the intrapericardial space by sliding it through said first catheter such that the distal end of said first electrode is extended beyond the distal end of said first catheter and is located proximate to the heart;
passing a second catheter through the pericardial sac and into the intrapericardial space such that it terminates in a distal end positioned proximate to the heart;
inserting a second electrode having proximal and distal ends into the intrapericardial space by sliding it through said second catheter such that the distal end of said second electrode is extended beyond the distal end of said second catheter and is located proximate to the heart; and
,fastening the first and second catheters to the pericardium or the surrounding connective tissue such that the catheters and the electrodes are held in a generally fixed position.

Abstract
A method and apparatus for implanting an automatic implantable defibrillator without the need for major surgery is disclosed. Preconfigured electrodes are straightened by the use of a stylet or by the surrounding catheter and inserted into the intrapericardial space through catheters. The catheters may be removed or may be left in place and attached to the pericardium or surrounding tissue to hold the electrodes in place.
