    摘要: A cardioversion or defibrillation system including a cardioverter or defibrillator and a lead. The lead carries a single cardioversion/defibrillation electrode formed of one small diameter metal filament for location in a heart chamber and may include a pace/sense electrode. The small diameter defibrillation electrode extends distally from the distal end of the lead body and may have the length of its extension adjusted by means of a movable sheath.

    摘要: A conductor assembly for a medical electrical lead includes a web and plurality of conductors. The web includes a plurality of longitudinally extending elements, or sidewalls, each of which define a longitudinally extending lumen, and a plurality of longitudinally extending connectors, each of which join a pair of adjacent sidewalls. Each of the plurality of conductors extends within a corresponding lumen, and each may include an insulative jacket. If each conductor includes an insulative jacket, the jacket is preferably formed from one or more of the following materials: PEEK, PVDF and polysulfone. One or more of the connectors of the web may be flexible to allow for a connected separation, or a gap between adjacent sidewalls; and one or more of these connectors may further include a discrete wall section adapted to facilitate widening of the corresponding gap. Preferably the conductor assembly is coiled for incorporation into the lead.

    摘要: In an endocardial, active fixation, screw-in lead of the type having a fixation helix (14) adapted to be rotated in a first advancement direction out of an electrode head chamber and into cardiac tissue by rotation of a lead connector end and attached lead conductor (18) with respect to an insulating sheath (12) in the first direction and retracted into the chamber (50) by rotation of the lead connector in the opposite retraction direction, a retraction stop mechanism (60) for preventing over rotation of the helix (14) in the retraction direction. The rotational motion of the lead conductor (18) is transmitted to the helix by a connecting assembly (52) and is translated into axial advancement and retraction of the helix by a guide (70) cooperating with the helix turns. A retraction stop mechanism (60) stops rotation of the helix in the retraction of the helix into the chamber and allows rotation of helix in the advancement direction. The retraction stop mechanism includes a fixed stop (62) formed of a plurality of fixed cam (66) and axial stop surfaces (68) surrounding a proximal end bore of the chamber through which the lead conductor passes and a movable stop (64) formed in the connecting mechanism of a like plurality of rotatable cam (76) and axial stop surfaces (78) aligned to face the fixed cam and axial stop surfaces adapted to engage in a locked relation of the stop surfaces upon full retraction of the fixation device into the chamber.

    摘要: A cardiac transvenous defibrillation lead has a continuous coil conductor within a layer of insulation. A portion of the coil conductor is exposed as a defibrillation electrode. In order to enhance fluoroscopic visualization of the exposed electrode during implant, the end of the exposed electrode is marked with a radiopaque element. The element may be in the form of an adhesive filled with radiopaque material that is used to backfill under the layer of insulation. Alternativelly, a tube made of radiopaque material may be installed between the layer of insulation and the coil conductor.
