Ronald W Heil Jr, Robert C Owens: Implantable tapered spiral endocardial lead for use in internal defibrillation. Cardiac Pacemakers, Haugen and Nikolai, May 21, 1991: US05016808 (157 worldwide citation)

An improved electrocardial lead for use with an automatic implantable cardioverter/defibrillator (AICD) comprises an elongated, flexible, plastic tubular catheter body which is preformed so that when unconstrained, it assumes the shape of a tapered spiral or helix. The catheter body supports a defib ...
