Filed:

Jun 27, 2000

Appl. No.:

09/604455

International Classification:

B26D 311

US Classification:

82 111, 83 53, 83880, 409 76

Abstract:

Spiral electrodes and similar structures are manufactured using a high-pressure fluid stream. Specifically, spiral electrodes are made from tubular structures by using a high-pressure water stream to precisely cut, or etch spirals of predetermined geometries to conform to a particular current distribution and conduction requirements. In an embodiment, the high-pressure water stream is tangentially and rotatably oriented against a rotating and translating tubular element. The tangential orientation enables limited cutting or etching of the tubular surface that is only in direct contact with the high pressure stream. Various geometries and spiral structures could be formed by managing the pressure and rotation of the high-pressure water stream source and the rotation and translation of the tubular element.

Appl. No.:

8/056448

Inventors:

James T. Gates - Maple Grove MN

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

H01R 4300

US Classification:

29875

Abstract:

A substrate for use in a pacing lead having a sintered porous platinized steroid eluting electrode. The substrate has at least one raised surface which provides an advantageous mounting portion for the sintered electrode. In the preferred embodiment the mounting portion is nailhead-shaped. The present invention provides an electrode produced with increased dimensional consistency, mechanical strength and impedance as compared to electrodes having a straight wire substrate. Also disclosed is a method of manufacturing such an electrode.

Appl. No.:

8/450761

Inventors:

James T. Gates - Maple Grove MN

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 105

US Classification:

607126

Abstract:

The present invention is a transvenous lead having an anchoring sleeve retaining device. The transvenous lead features a lead covered by an insulative sleeve. Positioned at the distal end of the lead is an electrode assembly. Also positioned proximate the electrode assembly is a fixation mechanism. At the proximal end of the lead body is a terminal assembly. The terminal assembly permits the lead to be connected to a pulse generator. The anchoring sleeve retaining device further features a removable portion that frictionally engages the lead and prevents the anchoring sleeve from sliding along the lead prior to suturing the anchoring sleeve to the lead.

International Classification:

A61N 105

US Classification:

607127

Abstract:

A medical electrical lead system having a torque transfer stylet. In a preferred embodiment, the torque transfer stylet comprises an elongated, stylet wire having proximal, intermediate and distal sections. The proximal and distal section of the stylet wire have a first diameter. The intermediate section spans between the proximal and distal sections. The stylet wire in this region, however, has a second diameter, the second diameter smaller than the first diameter of the proximal and distal sections. In addition, the intermediate section further has a length of torque coil wrapped thereabout. The torque coil preferably is wound in a coiled diameter which is the same as the first diameter of the proximal and distal sections of the stylet wire. Through such a configuration the stylet has an overall nearly uniformed diameter through its length.

Inventors:

James T. Gates - Maple Grove MN

International Classification:

A61N 105

US Classification:

607127

Abstract:

A stylet-actuated, steroid-eluting, screw-in, endocardial, transvenous bipolar pacing lead. In an embodiment, the lead is provided, with a sharpened helix. Advancing and retraction of the helix is accomplished with a stylet having a flattened, screw-driver tip. Rotation of the stylet imparts rotation to the helix assembly, causing the helix to advance or retract. A segmented tip electrode having a porous coating thereon allows steroid from a monolithic controlled released device housed within the electrode assembly to be eluted at the location of the implant site.

International Classification:

US Classification:

128642

Abstract:

An improved electrode for establishing electrical contact with a nerve of a patient. This electrical contact may be used to sense neural activity on the nerve or to artificially stimulate it to perform various medical treatments. The electrode has an outer cuff of an insulating material which is sutured around the nerve to be contacted. A drug impregnated layer of material is positioned inside of the outer cuff. This material is a polymeric matrix which permits the drug to leach out at a predetermined rate. The drug is a steroid such as dexamethasone sodium phosphate. The actual electrical contact is produced by metallic foil which is positioned on the surface of the drug impregnated layer of material which is located inside of the cuff. An insulated lead electrically couples the metallic foil to an electronic circuit located remote from the nerve. The leaching out of the drug serves to control irritation, swelling, and impedance of the nerve/electrode interface.
