Abstract
An epicardial defibrillator lead which is placed into a paracardial space adjacent the phrenic nerve and is supported in position by the paracardium wall. A soft-nosed, rounded, blunt-nosed introducer provides for positioning of the defibrillator lead in the paracardial space. The electrode is formed on one side of a polymer member, which is conforming to the left ventricle and the paracardium wall. The electrode has a polymer backing to insulate the electrode from the paracardium wall. The electrode of the defibrillator lead conforms to the geometrical shape of the left ventricle.
Claims2
A cardiac defibrillator lead for insertion through a small incision or percutaneous in the pericardial wall of a heart comprising:
- a. a first insulating member outer surface;
- b. a second insulating member outer surface spaced apart from said first insulating member outer surface and including a defibrillator electrode on said second insulating member outer surface;
- c. an electrical lead connected to said electrode;
- and,
- d. inflation means between said insulating member outer surfaces for extending said outer surfaces outward after insertion of said cardiac defibrillator lead.
