Abstract: An endocardial lead comprising an elongate body having a first defibrillation coil electrode, a second defibrillation coil electrode and a first pacing/sensing electrode. The first defibrillation coil electrode has a first end and a second end, where the first end is at or near the distal end of the elongate body and the second end spaced longitudinally from the distal end. The first pacing/sensing electrode is spaced longitudinally along the peripheral surface from the second end of the first defibrillation coil electrode. The second defibrillation coil electrode is spaced longitudinally along the peripheral surface from the first pacing/sensing electrode to afford positioning the first defibrillation coil longitudinally adjacent an apical location of the right ventricle of a heart with the first pacing/sensing electrode within the right ventricle of the heart and the second defibrillation coil within the right atrial chamber or a major vein leading to the right atrial chamber of the heart.

Abstract: A sutureless myocardial positive fixation lead implantation device is disclosed. An inner plastic rod is encased in an outer plastic sleeve. The outer plastic sleeve is affixed to a handle in which a central bore has been introduced. The inner rod is of sufficient length that a small length extends proximally from the handle when it is positioned within this bore, and it simultaneously extends the full length of the outer plastic sleeve. A suction cup is affixed to the distal end of the outer plastic sleeve. A holder means for receiving the proximal end of a typical myocardial lead is affixed to the handle to ensure that the lead is held taut and, thus, prevents entanglement during use.A specially designed smooth electrode head is pressed against the suction cup so that a lead having a corkscrew shaped electrode projecting from the head can be held by the device while it is rotated into place.
