  • Patent number: 6687549
    Abstract: An implantable endocardial lead intended for use with a cardiac stimulation device includes an elongated lead body of flexible resilient material, for example, silicone rubber or polyurethane, having a longitudinally extending lumen defined by a plurality of longitudinally extending side wall surfaces, adjacent pairs of the side wall surfaces lying in angularly disposed planes and intersecting at an energy absorbing corner ridge. An electrical conductor is located loosely within and extends longitudinally along the lumen between proximal and distal ends. With this construction, forces imposed laterally on the lead body by the conductor engaging the side wall surfaces of the lumen upon bending of the lead body are absorbed without damaging the lead body by reason of engagement of the conductor with a corner ridge causing the corner ridge thereby engaged to recede toward a condition of being coplanar with its subtended pair of side wall surfaces.

  • Publication number: 20030220677
    Abstract: An implantable stimulation lead is disclosed for placement in the coronary sinus region and its associated coronary vessels overlying the left side of a patient's heart. The lead comprises at least one proximal connector; at least one tissue stimulation electrode; at least one conductor coupled between the at least one proximal connector and the at least one stimulation electrode; and a lead body including a housing of insulating material enclosing the at least one conductor, the lead body having a relatively flexible distal portion of, for example, silicone rubber, having a length corresponding to the coronary sinus region of the heart, and a stiffer proximal portion of, for example, polyurethane. A robust transition joint comprising telescoped sections of the distal and proximal portions of the lead body couples the two portions of the lead body.

  • Patent number: 6634796
    Abstract: Devices and methods are described that permit simple correction of a fiber optic polarity reversal problem. An adapter is described having receptacles to receive a connector on a first end, or user end, and on a second end, or contractor end. Both the receptacles provide keying arrangements so that the connectors can be received only when correctly oriented with respect to the adapter. The keying arrangement on the contractor end, however, is reversable so that the connector may be inserted in one of two predetermined orientations, at the behest of the contractor or installer. Adapters are also described that receive connectors only in a physically reversed orientation to counteract a reverse polarity condition. In addition, a jumper is described that can be interposed between a connector and adapter to correct a reverse polarity condition.

  • Publication number: 20030112964
    Abstract: A housing is provided for interconnecting customer premises equipment with a digital subscriber line (DSL) at a location remote from a telephone company central office. The housing includes a base defining an interior cavity and at least one xDSL/POTS splitter positioned within the interior cavity. The splitter combines a POTS signal and a data signal from the central office into a combined signal on the DSL and separates a combined signal on the DSL from the customer premises equipment into the POTS signal and the data signal. In a particular embodiment, a back-plane circuit board having at least one card socket connector is positioned within the interior cavity and the splitter is mounted on a circuit card having a board edge connector. The board edge connector is received within the card socket connector to electrically connect the splitter to the back-plane circuit board.

  • Publication number: 20030074040
    Abstract: An implantable stimulation lead system comprises a lead including a lead body dimensioned for placement inside the coronary sinus region. The lead system further comprises a device dimensioned for insertion within a lumen in the lead, the device including a main body; a steering knob secured to a proximal extremity of the main body; and a flexible distal portion secured to a distal extremity of the main body. The main body has a length such that, with the main body of the device substantially completely advanced within the lead, the flexible distal portion of the device projects distally from the aperture in the distal tip of the lead body. The flexible distal portion of the device may comprise a proximal section and a distal section, the distal section being more flexible, and thus softer, than the proximal section.

  • Publication number: 20030050681
    Abstract: An implantable cardiac lead system suitable for placement in the coronary sinus region of the heart. The lead system comprises a lead having two or more non-helical bends in its distal portion. The two or more non-helical bends cooperate to prevent the lead from dislodgment or displacement inside the coronary sinus. The lead system may further comprise a stylet suitable for steering the lead into at least one of the coronary sinus vein, great cardiac vein, left marginal vein, left posterior ventricular vein, and small cardiac vein. The stylet is tapered in its distal portion to provide enhanced maneuverability and steerability inside the coronary sinus region. The lead system may also comprise an introducer which aids in introducing the lead into the heart.

  • Patent number: 6501993
    Abstract: An electrode assembly including a tip electrode and a longitudinally extending axially aligned weld electrode egageably receiving a distal end of a coiled wire strand conductor at a proximal end. A connector member includes a fastener having an enlarged head and a threaded shank, the weld electrode includes an integral weld sleeve with an annular locking tab engageable with the enlarged head to prevent longitudinal movement while permitting rotational movement. The weld electrode has an internal bore for receiving an elongated stylet selectively engageable therewith for implanting and explanting the electrode assembly. The tip electrode includes an integral attachment sleeve having an outer peripheral surface extending in a direction away from the tip and having a longitudinally extending tapped bore for engagement with the threaded shank of the connector member. The weld sleeve and attachment sleeve are mutually stepped to prevent their relative rotation when in the locked position.

  • Patent number: 6459937
    Abstract: A body implantable lead assembly includes a lead body and a tip electrode assembly at the distal end of the lead body. The tip electrode assembly is detachably connected to the lead body by means of a threaded coupling actuatable by a stylet inserted through the lumen of the lead body. The lead body may therefore be removed leaving behind a chronically implanted tip electrode assembly. The invention has particular utility in the context of passive endocardial heart pacing leads whose tip electrode assemblies include tines which become entangled in the trabecular network of the heart, and are therefore difficult to remove.

  • Patent number: 6457874
    Abstract: A mixed media outlet is provided that is capable of being mounted upon a wall and that includes ports that are typically designed to provide separate access to an electrical network and to an optical network. The wall mounted outlet can therefore permit a telephone to be connected to the electrical network, and a computer to be connected to the optical network. Alternatively, the outlet can permit a telephone to also be connected to either the same or a different optical network than the computer. The mixed media outlet includes a housing adapted to be wall mounted and first and second ports that are disposed within openings defined by the housing, such as a data port and a voice port.

The active electrode surface preferably has an area less than about 1 mm2. An MCRD, in the form of a collar, may be carried by a proximal portion of the tip electrode. Supplementing a set of main tines projecting from the distal end portion of an insulating sheath housing the lead assembly is a set of nubby auxiliary tines extending from the sheath immediately adjacent the distal extremity thereof.
