    摘要： A method for cardioverting or defibrillating a human heart, performed by placing a transvenous lead having a cardioversion or defibrillation electrode such that the electrode is located at least partially within the middle cardiac vein of a patient's heart and placing an additional cardioversion or defibrillation electrode in the superior vena cava of the patient's heart and thereafter delivering a cardioversion or defibrillation pulse between the first and second electrodes. The method may be practiced by placing the transvenous such that the defibrillation electrode it carries extends around the apex of the patient's heart, and the transvenous lead may be advanced through one cardiac vein toward the apex of the patient's heart and thereafter advanced upward through a different cardiac vein.

    摘要： An introducer is structured with an elongated tube having first and second lumens. A molded handle is coupled to the proximal end of the tube with an opening aligned with the first lumen. Further, a wall adjacent the opening of the handle defines a slot and is located diametrically opposite the second lumen. A tubular reinforcement member is located within the second lumen and the handle is provided with a second opening, thereby having a communication with the second lumen. In another embodiment a lead/catheter introducer includes an implantable lead or catheter having an elongated first lumen through which the lead or catheter passes and a second lumen extends parallel to the first lumen along at least a distal portion thereof. A tubular reinforcement member is disposed within the second lumen. The tubular reinforcement member further includes an internal lumen and a curvable stylet disposed in the lumen.

    摘要： A method of producing a lead which is isodiametric or nearly so over the region in which an elongated coiled electrode is located and which can optionally be manufactured starting from a single extruded tubular lead body of constant diameter and the lead so produced. Rather than molding the electrode into the surface of the lead or machining the electrode so that it is flush with the surface of the lead, the present invention instead employs an extruded, multiple lumen lead body of circular cross-section which has material cut away or otherwise removed in one or more regions spaced from one another around the lead body and extending longitudinally along the region of the lead body where the coil electrode is to be located or a lead body which is so molded. The areas in which material is removed or is absent are preferably located in regions where the lead body wall is thickest, for example between adjacent lumens. The removal of material may result in one or more elongated, generally planar surfaces spaced from one another around the circumference of the lead body or may result in elongated indentations spaced from one another around the circumference of the lead body. The removal or absence of material renders the lead body more compressible in the region the electrode is to be located.

    摘要： A guiding accessory, for use in conjunction with a guidewire and a catheter of an implant system, facilitates passage of an elongate and flexible conductor of a relatively compact therapy delivery device to an implant site, for example, within the cardiac venous system, when a therapy generator of the device is held within a distal portion of the catheter, and the catheter, device and guiding accessory are advanced along the guidewire. The guiding accessory includes a helically extending wall that forms a lumen within which the device conductor and guidewire extend. After advancing the catheter, guiding accessory and device to the implant site, the helically extending wall is unwound from around the device conductor, for removal, preferably, by pulling proximally on a tension line, which is attached to a proximal end of the wall.

    摘要： An instrument including an elongated shaft and a non-conductive handle is disclosed. The shaft defines a proximal section and a distal section. The distal section forms an electrically conductive tip. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. The instrument is useful for epicardial pacing and/or mapping of the heart for temporary pacing on a beating heart, for optimizing the placement of ventricular leads for the treatment of patients with congestive heart failure and ventricular dysynchrony and/or for use in surgical ablation procedures.
