US Patent:

62657747, Jul 24, 2001

Filed:

Nov 19, 1998

Appl. No.:

9/195930

Inventors:

Michael D. Sholley - Long Beach CA
Jeffrey B. Mitchell - Encino CA
Gregory K. Barber - Torrance CA

Bruce E. Osgood - Moreno Valley CA

Assignee:

TRW Inc. - Redondo Beach CA

International Classification:

H01L 2334

US Classification:

257728

Abstract:

Development of Millimeter Wave Devices containing MMIC's is expedited by use of a new package for the MMIC's and associated electrical components that define the functional circuit. The package includes a base plate and a plurality of metal inserts removeably fastened to the base plate. The inserts are spaced apart and contain a profiled edge with the profiled edge in one in confronting spaced relationship with that of another of the inserts. Together with the backplate, the profiled edges define elongated cavities, serving as two of the cavities side walls. The cavities serve as a repository for the MMIC devices and some of the additional components and stripline. Should extraneous resonances be discovered, the insert can be removed and adjusted in size and profile, and replaced, thereby adjusting the cavity without disturbing the electronic components or MMIC's which are secured to the back plate. The foregoing eliminates the restrictions imposed by the prior use of mouseholes and avoids the need for rebuilding the entire housing.

B29C 45/00

Abstract:

In one embodiment, a method for fabricating a neurostimulation stimulation lead comprises: providing a plurality of ring components and hypotubes in a mold; placing an annular frame with multiple lumens over distal ends of the plurality of hypotubes to position a portion of each hypotube within a respective lumen of the annular frame; molding the plurality of ring components and the hypotubes to form a stimulation tip component for the stimulation lead, wherein the molding fills interstitial spaces between the plurality of ring components and hypotubes with insulative material; and forming segmented electrodes from the ring components after performing the molding.
