摘要： A medical electrical lead adapted to stimulate a patient's cardiac plexus includes a flexible distal portion having a surface adapted to conform to an outer surface of an aortic region generally associated with the cardiac plexus. The distal portion can have one or more elongate members. Alternatively, the distal portion can have a generally planar portion. The distal portion is flexible such that it can be furled or otherwise compacted such that it can be delivered to a target stimulation site using a guide catheter or other delivery tool, such as a cannula.

摘要： A medical electrical lead for implantation in a patient's internal jugular vein at a target location and adjacent a vagus nerve. The lead comprises a proximal region having a proximal stiffness and a distal region. The distal region has a distal stiffness and a first spiral configured to retain the distal region in the internal jugular vein. A transition region is interposed between the proximal and distal regions and has a transitional stiffness. An electrode is coupled to the distal region. The proximal stiffness is less than the distal stiffness so as to reduce an amount of force transferred from the proximal region to the distal region. The transitional stiffness is less than the distal stiffness and greater than the proximal stiffness.

摘要： A lead delivery system for delivering a medical electrical lead to an internal jugular vein (IJV) through a subclavian vein. An inner catheter extends from a proximal end to a distal end. The inner catheter includes an inner catheter curve configured to direct the distal end to the IJV when positioned in the subclavian vein. The stiffness of the inner catheter decreases in an inner catheter transition region in a direction from the proximal end to the distal end. An outer catheter extends from a proximal end to a distal end and is sized to slide over the inner catheter. The outer catheter includes an outer catheter curve. The stiffness of the outer catheter decreases in an outer catheter transition region in a direction from the proximal end to the distal end. The system further comprises a guidewire having a distal end and a proximal end. The guidewire is sized to slide through the inner catheter to a desired location in the IJV and the guidewire stiffness decreases in a guidewire transition region in a direction from the guidewire proximal end to the guidewire distal end. A method of delivering a medical electrical lead to a target location within an IJV.

摘要： An improved guidewire for assisting in implantation of a cardiac lead includes three sections. The most distal zone is sufficiently floppy to prevent trauma to the vessel walls through which the guidewire and lead are inserted. An intermediate zone is generally stiffer and has a cross-section less than or equal to the cross-section of the distal zone. The third zone is stiffer yet and is joined to the intermediate zone by a shoulder. The shoulder cooperates with protrusions on the lead to transfer forces between the guidewire and lead. A removal wire having temporary locking device to lock the removal wire to the lead is employed to remove the guide catheter without moving the lead from its desired location. Lubricious coatings are also provided to reduce friction between the lead and guidewire.

摘要： A body implantable lead for placement in a selected coronary vein includes a resilient retention structure for inhibiting displacement of the lead because of heart beat action, breathing or other body movement. The retention structure includes a plurality of resilient projections that are attached to the lead body and which are adapted to project at a predetermined acute angle to the axis of the lead body when unconstrained. Prior to being routed through the vascular system, the projections can be bonded to the lead body to provide a low profile with a biodegradable adhesive. Following exposure to body fluids, the adhesive dissolves, releasing the projections so that they can engage the walls of the vein in which the lead is disposed.

摘要： An intravenous lead for use with a cardiac device for implantation in the coronary venous system of the heart includes a lead body that is adapted to be routed through the vascular system into the coronary sinus with the distal end portion of the lead placed in the great cardiac vein or branch vein. The lead body includes a fixation member disposed just proximal of its tip. The fixation member comprises a radially expandable polymeric matrix that incorporates an osmotic agent so that when placed in a aqueous medium it will swell. Thus, when placed in a cardiac vein, the swelling of the fixation member will anchor the lead against longitudinal displacement due to body motion, blood flow and the beating action of the heart.

摘要： An implantable tissue stimulator includes a polymer film capacitor adhered to an inside wall surface of the stimulator's case or housing in a way that minimizes the size and weight of the stimulator device. The energy storage capacitor for the tissue stimulator comprises a monolithic, multi-layer device and where the polymer is a suitable acrylate of a known formulation, over 1500 parallel plate capacitor electrodes can be built it with the height dimension of the resulting capacitor being less than about 3 mms. Instead of forming the capacitor on the inner surface of the stimulator's case in situ, such a capacitor can be formed on a mold member corresponding in shape to the inner surface of the stimulator's case and inserted into the stimulator's case following removal from the mold.
