Abstract
Abstract An internally deployable resilient continuous electrode assembly for placement through a catheter comprises a distortable electric conductor movable through the catheter in a first position and deployable therefrom in a second position onto the epicardial surface of the heart without the need of a general anesthetic and minimizing the risk for the patient. The distortable electric conductor has a plurality of distortable flat conductor strips conductively connected at their ends to the distortable electric conductor so as to provide an enlarged surface area of contact with the heart for defibrillating episodes.
