    摘要: A helical element for insertion into tissue comprises a helical element having an insertion end, a protruding end and an open central area within the wire, rods, filaments, cables or the like that form the helix. The helical element has at least its insertion end covered by a cap of a water-soluble or water-dispersible composition. The cap is provided with a surface shape in a cross-section in which surface variations are present in the cross-section which create a surface orientation where a line from the center of the cross-section can intersect the surface, and a line perpendicular to said radius at a point of intersection with said surface forms four quadrants, three of said quadrants containing water-soluble or water-dispersible cap material. There is either a hollow area within the composition within the open central area or the material is more porous than the remaining material. The helical element preferably comprises an electrical lead, such as a positive endocardial lead, with an electrode at the protruding or distal end of the lead. The helical element may comprise any biocompatable material with sufficient structural integrity to provide a secure attachment to tissue in a patient. Where the helical element is also to provide an active (electrically active) function, the composition of the helical element should also be electrically conductive.

    摘要: A cardiac rhythm management system provides an endocardial cardiac rhythm management lead with an at least partially dissolvable coating at least partially on insulating portions of the lead body at or near its distal end. Upon dissolution, the coating promotes tissue ingrowth to secure the lead in place within fragile vascular structures or elsewhere. Dissolution of one such coating releases a therapeutic agent, such as a steroid that modifies the fibrotic scar tissue content of tissue ingrowth, such that the resulting bond between the tissue and the lead is weak, so that the lead can be easily extracted if desired. One such lead includes an insulating elongate body carrying at least. The lead also includes an at least partially dissolvable coating on an insulating portion of the peripheral distal lead surface. The coating provides one or more of a rough surface, a porous surface, or a swollen surface after being exposed to an aqueous substance.

    摘要: An elongated monopolar or bipolar coronary vein lead having a reduced outer diameter and especially adapted to be advanced into a selected coronary vein for delivering a pacing signal to a predetermined region of a patient's heart, such as the left ventricle. A method of using the lead for pacing a patient's heart in the treatment of heart failure is also described. The method for pacing the heart includes advancing the coronary vein lead through both the coronary sinus and into a selected coronary vein of a patient's heart, connecting the lead to an electrical pacing source and applying electrical stimulation to a particular chamber of the patient's heart via the implanted lead. The lead includes a flexible tip and transition ring that enhances the ability to guide the lead through the coronary veins.

    摘要: An implantable system for ambulatory monitoring of a high-risk heart failure patient includes a first pressure sensor implantable within an abdomen of the patient for sensing and generating an output representative of a baseline intra-abdominal pressure value of the patient and for chronically sensing and generating an output representative of an intra-abdominal pressure value of the patient at periodic intervals. At least one second implantable sensor is provided for sensing and generating an output representative of a second physiological parameter of the patient. Additionally, the system includes a processor for correlating the output of the first pressure sensor and the second physiologic sensor, and for comparing differences between the baseline intra-abdominal pressure value and subsequent intra-abdominal pressure values. The processor can reside in another implantable device or in an external device/system.

    摘要: A data logging system and method in which an implantable medical device transmits logged data to an external data logging device with low energy potential signals. The implantable device generates potential signals modulated with digitally encoded data by operating a current source to cause corresponding electrical potentials that can be sensed at the skin surface by the external data logging device. The data logging device then demodulates the sensed potentials to derive the digital data and stores the data in a data logging storage medium.

    摘要: An improved electrocardial lead for use with an automatic implantable cardioverter/defibrillator (AICD) comprises an elongated, flexible, plastic tubular catheter body which is preformed so that when unconstrained, it assumes the shape of a tapered spiral or helix. The catheter body supports a defibrillating electrode attached to the exterior wall of the catheter body and is connected by a suitable cable to a proximal connector for mating with the AICD pulse generator. The improved lead also includes a tip electrode for sensing cardiac activity and providing information to the AICD pulse generator for controlling its operation. The lead of the present invention is intended for endocardial emplacement with the electrode structures predominantly in the right ventrical and provides substantially increased electrode surface area in contact with heart tissue as compared to prior art endocardial defibrillating leads and, thus, maximizing the energy delivered to the heart during defibrillation.
