  • Patent number: 6643550
    Abstract: A connector for connecting to an energy source such as a pulse generator for a cardiac stimulator system. The connector assembly includes a pin, at least one ring and a sleeve composed of an insulative hard polymer molded between the pin and ring such that the sleeve provides electrical insulation between the pin and ring and mechanically couples the pin and ring.

  • Publication number: 20030074031
    Abstract: A connector assembly of an electrophysiologial device. The connector assembly includes a substrate forming a tube extending from a proximal end to a distal end an electrical circuit formed on the substrate, such as etching or printing, where the substrate is optionally non-conductive. In another option, the connector assembly includes clad wires and/or flexible circuits within an insulated terminal structure.

  • Publication number: 20030069625
    Abstract: A lead includes a lead body extending from a distal end to a proximal end, and at least one conductor disposed within the lead body and extending from the distal end to the proximal end of the lead body. The lead further includes an outer terminal ring, a terminal pin, and an insulative sleeve disposed between the outer terminal ring and the terminal pin, where the insulative sleeve is coupled with the outer terminal ring with a snap-fit connection. A pin latch is disposed on an outer periphery surface of the insulative sleeve, where the pin latch is rotatable about a hinge point.

  • Publication number: 20030040787
    Abstract: A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process.

  • Publication number: 20020165442
    Abstract: 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.

  • Patent number: 6361780
    Abstract: A drug delivery device is described comprising a porous biocompatible solid having at least one therapeutic drug within its pores, the therapeutic drug being removable from the pores by immersion in an aqueous solution. This may also be described as a drug delivery device comprising a porous annulus comprising a biocompatible solid having at least one therapeutic drug within its pores, the therapeutic drug being removable from the pores by immersion in an aqueous solution, the annulus having a top outer surface with an outside diameter, an inner surface with an inside diameter, and a side surface, at least one of the side surface and the top outer surface having openings of the pores exposed on that surface. The device may comprise pores having an average size of the greatest dimensions within the pores of between about 10−6 and 10−1 mm. The device may have a medical device or component of a medical device pass through an opening in the annulus.

  • Patent number: 6360129
    Abstract: 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 composition of the cap comprises a water-soluble or water dispersible component having a hydrogel mixed therein. In one embodiment, 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.
