Abstract:
An apparatus for delivering subcutaneous cavity marking devices. More particularly, the delivery devices may be used with biopsy systems permitting efficient placement of a biopsy marker within a cavity. The device may include an intermediate member which assists in deployment of the marking device. The devices may also include a deployment lock to prevent premature deployment of a biopsy marker. The invention may further include the capability to match an orientation of a biopsy probe which has been rotated upon procurement of a biopsy sample.
Abstract:
A substrate processing system is provided with a housing defining a process chamber. A substrate holder is disposed within the process chamber and configured to support a substrate during substrate processing. A gas delivery system is configured to introduce a gas into the process chamber. A pressure-control system is provided for maintaining a selected pressure within the process chamber. A high-density-plasma generating system is operatively coupled with the process chamber and includes a coil for inductively coupling energy into a plasma formed within the process chamber. It also includes magneto-dielectric material proximate the coil for concentrating a magnetic field generated by the coil. A controller is also provided for controlling the gas-delivery system, the pressure-control system, and the high-density-plasma generating system.
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.

Abstract:
Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.
Abstract:
Implantable connector devices which are useable to maintain fluidic connection between, or approximation of, openings formed in adjacent natural or prosthetic anatomical conduits (or adjacent openings formed in a single anatomical conduits). These connector devices generally comprise a plurality of radially expandable annular members having one or more elongate strut members extending therebetween. Initially, the device is mountable on or within a delivery catheter while in a radially compact configuration. After the delivery catheter has been inserted into the body, the device is caused to transition to a radially expanded configuration whereby it becomes implanted within the body so as to maintain the desired fluidic connection between, or the desired approximation of, the anatomical conduit(s).
Abstract:
An interface for a hollow core fiber is provided that facilitates the direct pigtailing of the hollow core fiber to a port on an electro-optic device. The interface includes an angled face that attaches to the electronic device at an angle that minimizes optical power loss as light propagates from the electronic device to the hollow core fiber.
Abstract:
The present invention is directed to systems, apparatus, methods and procedures for the noninvasive treatment of tissue using microwave energy. In one embodiment of the invention a medical device and associated apparatus and procedures are used to treat dermatological conditions using microwave energy.
Abstract:
An incendiary grenade's casing has a fuze with a portion extending into the casing. Thermite disposed in the casing encases the portion of the fuze that extends into the grenade casing. Insulating material is disposed in the casing adjacent to the thermite. Layers of a titanium-boron intermetallic and an oxidizer are disposed in the casing. One layer of the titanium-boron intermetallic is adjacent to the layer of insulating material. This one layer of the titanium-boron intermetallic and a layer of the oxidizer adjacent thereto have a common-axis hole formed therethrough that is aligned with the portion of the fuze. A separating material is disposed at each interface between the titanium-boron intermetallic and the oxidizer.
