US Patent:

7909227, Mar 22, 2011

Filed:

Dec 19, 2006

Appl. No.:

11/613054

Inventors:

Thach Duong - Tustin CA, US
Jenny C. Liu - Irvine CA, US
Jay J. Eum - Irvine CA, US

Assignee:

Endocare, Inc. - Austin TX

International Classification:

B23K 37/04

US Classification:

228 445, 228 493

Abstract:

A vacuum insulation tube assembly which is utilized as a component in a cryosurgical probe. The vacuum insulation tube assembly includes an inner tube; and, an outer tube concentrically positioned about the inner tube. The outer tube is securely soldered at end portions of the inner tube and forms a vacuum space between the inner tube and the outer tube. The vacuum tube assemblies may be conveniently mass produced using a special fixture.

International Classification:

A61F 7/12

US Classification:

604113000

Abstract:

The catheter includes a multi-lumen tube having an outflow portion and an accessory portion. The accessory portion is integrally formed within an interior volume of the outflow portion. The accessory portion has a cross-section smaller than the outflow portion. The outflow portion is offset from the accessory portion such that they are integrally joined. The space between these portions defines a fluid return passageway and the space within the accessory portion defines an accessory passageway. A flexible outer sleeve cooperates with the multi-lumen tube to form a fluid inlet passageway. During operation, an inlet flow of warming fluid flows through the fluid inlet passageway formed between the outer sleeve and the multi-lumen tube. The flow continues around a distal end of the outflow portion of the multi-lumen tube, thus becoming an outlet flow of the warming fluid which is directed through the fluid return passageway.

International Classification:

A61B 18/18

US Classification:

606041000, 604113000

Abstract:

An inlet flow of heat exchange fluid flows from an inflow housing inlet section, and through an inflow housing main section. It then flows through an inlet fluid passageway formed between an inner balloon and a discharge tube. The flow continues around a distal end of the inner balloon, thus becoming an outlet flow of the heat exchange fluid which is directed through an outlet fluid passageway formed between the inner balloon and an outer balloon, then through an outflow housing main section and finally discharged through an outflow housing outlet section. The inner balloon is in a position offset from the central axis of the catheter. The offset relationship enhances the fluid dynamic properties of the catheter. It provides an increased turbulence, which, in turn, maximizes the heat exchange efficiency.

Abstract:

An apparatus for automatically mapping a verbatim narrative to a term in a medical terminology dictionary includes a natural language processor and a comparator. The natural language processor processes terms from the medical terminology dictionary and from a medical coding decision database to generate a processed database that also includes the original terms from the medical terminology dictionary and the medical coding decision database. The natural language processor also processes the verbatim narrative. The comparator compares the processed verbatim narrative to the terms in the processed database and determines whether the processed verbatim narrative is an exact match to a term in the processed database. The verbatim narrative is mapped to the term in the medical terminology dictionary that corresponds to the term in the processed database that is an exact match. The verbatim narratives may include adverse event narratives, concomitant medication narratives, or other types of narratives. A method for automatically mapping a verbatim narrative to a term in a medical terminology dictionary is also described and claimed.
