US Classification:

118715, 15634533, 15634534

Abstract:

A gas distributor for use in a semiconductor process chamber comprises a body. The body includes a first channel formed within the body and adapted to pass a first fluid from a first fluid supply line through the first channel to a first opening. A second channel is formed within the body and adapted to pass a second fluid from a second fluid supply line through the second channel to a second opening. The first and second openings are arranged to mix the fluids outside the body after the fluids pass through the openings.

Assignee:

Target Therapeutics, Inc. - Fremont CA

International Classification:

A61M 5178
A61M 500

US Classification:

604164

Abstract:

A catheter for use in combination with a guide wire for placement within a tortuous, small vessel and delivery of fluid at a target site is disclosed. The catheter comprises an elongate tubular body with a perforated flexible tip located at the distal end of the elongate tubular body.

Assignee:

Conceptus, Inc. - San Carlos CA

International Classification:

A61B 500

US Classification:

128772

Abstract:

The present invention sets forth a guidewire-type device which can be axially moved via application of axial force and/or by application of torquing force. The device is used for accessing regions within a body. The device is used to attach to subject material within a body, and, if desired, to remove the subject material. In particular, the device and method of the invention are advantageously utilized by health care practitioners for use in accessing tortuous and difficult body areas, such as fallopian tubes.

Assignee:

Target Therapeutics, Inc. - Fremont CA

International Classification:

A61M 2900

US Classification:

604 96

Abstract:

This invention is a microballoon tipped catheter. The catheter has a shaft which is of varying flexibility with the most flexible portion towards the distal tip. The balloon, located near the distal tip of the catheter, is typically of an elastic material, is quite flexible in its own right when deflated, and is quite small. The catheter shaft has a main lumen extending from the proximal end to the distal end so to allow the use of a guidewire in placing the catheter's distal tip in remote regions of the vasculature and for delivery of drugs, diagnostics, and other biologics to those regions. The catheter shaft has a wall that desirably is of a multilayer construction. The wall preferably includes an independent lumen, which may be formed from a small diameter tubing that is placed between layers of the wall, for the inflation and deflation of the microballoon. The inflation lumen proceeds from the proximal end of the catheter and terminates near the distal end of the catheter but within the microballoon. This catheter is especially useful in treating disease within the high pressure vessels of the brain with drugs or other therapeutic agents and permits temporary blockage of blood flow and thereby allow better absorption of those active agents.

International Classification:

A61B 1700
A61B 1708

US Classification:

Assignee:

Target Therapeutics, Inc. - Fremont CA

International Classification:

A61M 2500

US Classification:

604282

Abstract:

A catheter composed of an outer coaxial tube or relatively high flexibility and three tandemly disposed inner coaxial tube segments that vary in stiffness with the stiffest being located at the proximal end of the catheter and the least stiff ending proximal of the proximal end of the catheter. The catheter thus has four regions of different stiffness/flexibility.
