A lead having a pre-formed biased portion is adapted for implantation with a body vessel and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are biased toward a vessel wall by the preformed biased portion, which operates to fixate the lead against the vessel wall.

Coronary vein leads having pre-formed biased portions for fixation

A lead having pre-formed biased portion is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and are biased toward a vessel wall by the preformed biased portion, which operates to fixate the lead against the vessel wall.

Coronary vein lead having pre-formed biased portions for fixation

A lead having an atraumatic tip is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and are biased toward a vessel wall by a preformed biased portion. Near the distal end, the lead has an optional tapered portion and a flexible portion, where the flexible portion is more flexible than the biased portion.

Coronary vein leads having an atraumatic tip and method therefor

A laser welding fixture for holding a workpiece includes a base, a processing head adapted to magnetically couple to the base, and a collet. The processing head has at least one collet holder assembly and at least one stop. The collet is removably coupled to the holder assembly.

Laser welding fixture and method

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. The elongate body further includes a curved portion on which the first pacing/sensing electrode is positioned such that the first pacing/sensing electrode extends beyond the peripheral surface of the elongate body to engage the tissue of the heart. The first pacing/sensing electrode further includes a retaining element, where the retaining element is adapted to be embedded in the right ventricle of the heart to secure the first pacing/sensing electrode and the elongate body of the endocardial lead to the right ventricle of the heart.
