Sep 11, 2000

Appl. No.:

09/659466

Inventors:

Reid Cover - Mountain View CA
Thomas Martin Keast - Mountain View CA
Anthony Chikuo Lee - Mountain View CA
Sean Barry Cahill - San Jose CA

Assignee:

Stryker Corporation - Kalamazoo MI

International Classification:

A61M 100

US Classification:

604118, 604 32

Abstract:

A surgical fluid flow handpiece provides a range of relatively low flow rates with relatively fine manual control in selecting a flow rate in such relatively low range, and also provides for manual selection of a relatively high flow rate namely a flow rate well above such range. The handpiece is shaped to complement the shape of a users hand.

International Classification:

A61B018/18

US Classification:

606 33, 606 41

Abstract:

Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e. g. , a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e. g. , welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e. g. , ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

International Classification:

A61B 18/18

US Classification:

606 33, 606 41

Abstract:

High-strength microwave antenna assemblies and methods of use are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e. g. , a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. The antenna can be used individually or in combination with multiple antennas to create a combined ablation field. When multiple antennas are used, microwave energy can be applied simultaneously to all the antennas or sequentially between the antennas. Furthermore, to facilitate positioning the antennas in or near the tissue to be treated, RF energy may be applied at the tip of the antenna to assist in cutting through the tissue.

International Classification:

F41H 5/02

US Classification:

89 3602, 89 3604, 89 3607

Abstract:

An interface includes a blast plate having plate structure, the plate structure being formed to substantially conform to a certain portion of an exterior margin of a hull of a certain vehicle and being semi-permanently mounted to the hull by mounting to certain mounting devices present on the exterior margin of the hull and having mounting structure for supportively mounting a standardized add-on device, the mounting structure being designed to facilitate the add-on device being readily mountable on and demountable from the plate structure, the plate structure having structural characteristics for acting to protect the hull from effects of a blast directed at the hull. A modular assembly and a blast plate are further included.
