Filed:

Dec 13, 2012

Appl. No.:

13/713030

Inventors:

Steven J. Weiss - Silver Spring MD, US

Assignee:

U.S. Army Research Laboratory ATTN: RDRL-LOC-I - Adelphi MD

International Classification:

H01Q 19/10
H01Q 15/14

US Classification:

343819, 343834, 343912, 343913

Abstract:

An electromagnetic bandgap structure comprising a progressive cascade of a plurality of patterns of cells. The cells of each pattern are dimensioned so that each pattern has a reflection phase response centered at a different, but closely-spaced, frequency compared with the reflection phase response of an adjacently positioned pattern, so that the combined reflection phase response of the plurality of patterns provides a continuous wideband operational range.

Assignee:

Cavitron Corporation - New York NY

International Classification:

A61M 100
G05D 1111

US Classification:

128276

Abstract:

A fluidic control system for use in irrigation and aspiration of the anterior chamber of the eye during ultrasonic emulsification of a cataract therein. The system comprises a handpiece with an (ultrasonically vibrated) hollow tip, the hollow tip being connected to the fluid withdrawal or aspirating portion, while an annular passage around the tip is used to introduce fluid for irrigation purposes. The aspirating portion comprises a withdrawal hose attached to the output manifold of the handpiece in fluid communication with the hollow tip, a constant flow pump attached to the other end of the withdrawal hose, and a vacuum relief valve connected to the withdrawal hose intermediate the pump and the handpiece. The irrigation portion comprises a fluid supply bottle at a predetermined height above the eye, and administration set attached to the bottle, and an inflow hose attached to the intake manifold of the handpiece and in fluid communication with the annular passage. All the aforementioned components are in fluid communication with the anterior chamber of the eye during removal of a cataract by insertion of the handpiece tip into the eye chamber.

Stanley H. Enker - Lawrence NY

Assignee:

Cavitron Corporation - New York NY

International Classification:

A61B 1732

US Classification:

128305

Abstract:

Apparatus for use in surgically removing tumorous neurological tissue comprises a handpiece in which a tool tip vibrating transversely to its long axis in the ultrasonic range, is mounted an irrigation fluid outlet for introducing fluid adjacent the tool tip to flush the operative site, and a fluid inlet adjacent the tool tip for withdrawing a fluid mixture from the site.

Assignee:

Cavitron Corporation - New York NY

International Classification:

A61B 1732

US Classification:

128305

Abstract:

Method and apparatus are disclosed for use in surgically removing tumorous neurological tissue which apparatus comprises a handpiece mounting a hollow tool tip vibrating transversely to its long axis in the ultrasonic range, means for introducing fluid adjacent the tool tip to flush the operative site area, and means adjacent the tool tip for withdrawing the fluid mixture from the site. The method comprises applying an ultrasonically vibrated tool to tumorous nerve tissue, while simultaneously introducing irrigation fluid to flush the area of the tissue and withdrawing the resulting mixture from the area adjacent the tool.
