Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N001/375

US Classification:

607 36, 607 32, 607 60

Abstract:

An implantable medical device that includes an enclosure, an electrical module for the desired stimulation, sensing and communications functions, a power source, an air-core antenna, and supporting structures therefore. The antenna includes a quarter-elliptical shape that maximizes the antenna area to facilitate transmission of electromagnetic waves through the enclosure. A support structure is provided so that the antenna, the module and the battery self-align with each other and the enclosure. The support structure contains contacts to facilitate electrical connection of the antenna to the module and positions the module so that contacts thereon are in close proximity in plan and elevation to external electrical feed-throughs in the housing and the antenna contacts on the support structure. The support structure positions the antenna between the module and the housing, separated therefrom by a predetermined minimum distance to facilitate efficient coupling of electromagnetic waves to and/or from the antenna.

International Classification:

A61B 17/32

US Classification:

606170

Abstract:

A surgical cutting instrument for use with a drive motor, and related system and method, is described. The surgical cutting instrument includes an elongated drive member, a cutting tip secured to the drive member, a non-conductive coupling body adapted for connection to a motor assembly, a housing maintaining the coupling body, and an electrical connector for connection to a stimulating energy source. The electrical connector is in electrical communication with the cutting tip via an electrical pathway.

US Classification:

606170

Abstract:

Surgical micro-resecting and evoked potential monitoring system and method. The system includes a micro-resecting instrument, handpiece, and evoked potential monitor. The instrument includes an outer tube forming a cutting window at which a cutting tip of an inner member is located. A hub assembly rotatably maintains the inner and outer members. An electrically non-conductive material covers a region of the outer tube, and wiring is connected to an exposed surface of the outer tube. The instrument defines a probe surface proximate the cutting window as part of an electrical pathway with the wiring. The hub assembly is powered by the handpiece, and the wiring is connected to the evoked potential monitor. Evoked potential monitoring is performed at the probe surface via stimulation energy delivered along the electrical pathway, and tissue/bone resection occurs with rotation of the cutting tip.

Appl. No.:

Inventors:

David M. Reinker - Yorba Linda CA

Assignee:

Irvine Sensors Corporation - Costa Mesa CA

International Classification:

G02B 610

US Classification:

385132

Abstract:

A self-aligning optical beam system is disclosed in which optical alignment of two beam-carrying portions, such as a laser beam generated by a chip, and a light guide formed as a waveguide in a polymeric material, is precisely controlled by plug-and-socket connection between a substrate and a chip. Plugs in the form of solder bumps are formed on one surface of a laser chip, and are inserted in sockets provided in a substrate. The optical alignment is precisely controlled in three axes, two of which guarantee alignment for laser beam transmission into a waveguide, and one of which minimizes the gap across which the beam travels. A powerful waveguide division multiplexer may be provided by having numerous converging waveguides on a single substrate, and by stacking a number of substrates, all of whose waveguides feed into a single optical output channel.
