Appl. No.:

12/944507

Inventors:

Nirali PATEL - Murrieta CA, US
Cheng Yang - Carlsbad CA, US

International Classification:

A61B 17/56
A61B 17/00
A61F 2/44

US Classification:

606 86 A, 606 1, 623 1711

Abstract:

A surgical instrument for inserting an implant includes a first shaft having an axial bore and including a distal end configured to actuate a first feature of a spinal implant and a second shaft extending through the axial bore of the first shaft and including a distal end configured to actuate a second feature of the spinal implant. Rotation of the first shaft in a first direction actuates the first feature and causes rotation of the second shaft in a second direction to actuate the second feature.

Abstract:

A hermetically sealable millimeter waveguide launch transition feedthrough for channelling high frequency electrical signals in a circuit which includes at least one waveguide. An aperture is formed in one wall of the waveguide and a conductive pin passes through the aperture. The pin is sealed therein by a dielectric material which surrounds the pin so as to isolate it from the waveguide wall. A probe head is disposed at one end of the conductive pin and within the waveguide. The opposite end of the pin contains a second probe head or other circuit connector. The transition may be effectively implemented in waveguide-to-waveguide or waveguide-to-device applications as well as in colinear device housing applications.
