09/723961

International Classification:

Abstract:

A technique for removing an implanted lead from a body includes the steps of releasably attaching a stylet to both the distal end of the implanted lead and to the proximal end of the implanted lead. This results in a substantially unified stylet and implanted lead structure whereby withdrawal of the stylet and of the implanted lead as a unit facilitates the complete removal of the implanted lead from the body. A threaded tip end may be used for threaded engagement with a tapped bore at the distal end of the implanted lead and at the proximal end, attachment being provided by a threaded region on the stylet distant from the threaded tip end for threaded engagement with a tapped bore of a connector pin integral with the implanted lead. In this instance, the diameter of the proximal threaded region on the stylet is greater than that of the threaded tip end. In one embodiment, the implanted lead is resiliently extensible and the stylet is greater in length than the implanted lead in its relaxed condition and tension is applied to the proximal end of the implanted lead to thereby stretch it so that the proximal end of the implanted lead is generally coextensive with the proximal end of the stylet.

International Classification:

A61N 105

US Classification:

607126, 607122, 607127, 606108

Abstract:

A technique for removing from a body an implanted lead including an active fixation electrode includes the operation of releasably attaching an elongated stylet to the distal end of the implanted lead, specifically, to the electrode at the distal end of the lead. This results in a reasonably unified stylet and implanted lead structure whereby withdrawal of the stylet and of the implanted lead as a unit facilitates the complete removal of the implanted lead from the body. A threaded tip end of the stylet is used for threaded engagement with a tapped bore in the electrode. The threaded tip end of the stylet becomes locked to the electrode by rotating in one direction the threaded portion into the threaded bore and the stylet is removable by counter-rotating the threaded tip end of the stylet relative to the electrode.

US Classification:

439668, 439218, 439669

Abstract:

A connector assembly for coupling an electrical lead to an electrically energized device includes a non-conductive housing member with an elongated bore. A block member in the bore proximate the sealed end has a coaxial through bore. A first of multiple side by side pairs of seal assemblies and contact assemblies in the bore is proximate the block member, a last one is nearest the bore entrance. Each contact assembly has electrical commonality with a terminal of the device. A strain relief zone fixed to the housing member in the bore engages the last seal assembly and faces the bore entrance. Force on the strain relief zone toward the block member firmly seals in the bore all components defining a central passage coaxial with the through bore enabling electrical contact among multiple lead terminals inserted into the bore, an associated contact assembly, and an associated terminal of the device.

International Classification:

A61N 1/00

US Classification:

607 36, 128903

Abstract:

A housing for an implantable medical device comprises a metallic wall including a telemetry window having a thickness that is thinner than the remainder of the housing wall and having an electrical conductivity that is less than that of the remainder of the housing wall. In another embodiment, an implantable medical device casing comprises a metallic wall including a telemetry window received within an aperture defined by said casing wall, the window having an electrical conductivity that is less than that of the remainder of the casing wall. Pursuant to another embodiment, there is provided an implantable medical device incorporating a casing as described above that is hermetically sealed and encloses a transceiver for bidirectional telemetric communication through the telemetry window.

Abstract:

A connector assembly for an implantable medical device including a casing includes a header having a receptacle with an electrical contact for engageably receiving an electrical terminal on a proximal end of a lead and a fastener assembly for simultaneously releasably clamping the lead to the header within the receptacle and firmly attaching the header to the casing. The header is mounted on the casing and has a distal notched region with an upper surface and a first channel in its upper surface aligned with, and being a partial extension of, the receptacle. The fastener assembly includes a lead-lock component engageably received within the notched region of the header and with a second channel therein which is aligned and juxtaposed with the first channel, the channels taken together being an extension of the receptacle. A fastener system firmly mounts the lead-lock component to the header at the notched region.

International Classification:

A61N 1/00

US Classification:

607 4

Abstract:

A device and methods for automatically evaluating one or more patient physiological parameters and, upon determination that certain therapies are indicated, delivering therapeutic mechanical stimulations to tissue of the patient. The mechanical stimulations generally include vibrations delivered at frequencies somewhat higher or lower than an intrinsic frequency and the therapeutic vibrations are delivered to drive the intrinsic frequency towards a desired value. The device and methods more closely emulate natural physiologic feedback mechanisms and can reduce undesired side effects of other known therapies. The device can include a small and efficient electrical motor which is interconnected with a crank and link mechanism to generate oscillatory motion which is conducted to a flexible wall of a bio-compatible housing of the device.

International Classification:

A61N001/375

US Classification:

607/037000

Abstract:

A connector assembly mounted on an implantable cardiac stimulation device has an actuator mechanism for fixing electrical leads inserted into lead receptacles within the connector assembly without the use of setscrews. Fixing of the leads is accomplished by compressing onto each lead annular locking springs, disposed in annular recesses of a molded support and engaged with an annular shoulder of conical taper in the direction of lead insertion, with lip portions of a plunger drawn toward the molded support by the actuator mechanism. In a first embodiment, rotation of a cam actuator transversely journaled within the support, using a torque wrench or similar tool, moves a cam slide attached to the plunger through a fixed displacement between lock and unlock positions as an offset camming portion of the actuator engages the surfaces of a slot within the cam slide. In a second embodiment, constant-force compression of the annular lead locking springs by the plunger is provided by using a torque wrench to rotate a screw actuator having one end coupled to the plunger and an opposite threaded end received within a screw block transversely disposed within the support. In a third embodiment, a rotatable toothed pinion engages a toothed slot within a slidable rack to provide incremental advancement of the rack, and thereby stepped displacement and force. In a fourth embodiment, compliance provided by either a spring formed within the cam slide, or a spring nut mounted thereon, prevents excessive force from being exerted on leads of larger diameter.
