US Patent:

6494859, Dec 17, 2002
Filed:

Apr 28, 1999
Appl. No.:

09/301058
Inventors:

Susan M. Love - Pacific Palisades CA
David Hung - Belmont CA
Xuanmin He - Palo Alto CA
Assignee:

The Regents of the University of California - Oakland CA
International Classification:

A61M 100
US Classification:

604 28, 604 19, 604 27, 604 48, 604 73, 604 74, 604 75, 604 76
Abstract:

Methods, kits, and apparatus for obtaining cellular, chemical, and other materials from breast ducts are described. A single milk duct is accessed and washed with a washing fluid to obtain marker materials from the lining the duct. The washing fluid is then collected, and the marker materials in the washing fluid identified and analyzed. Usually, the washing fluid is introduced using a syringe through a lumen of a dual-lumen catheter. The ductal volume is filled with the washing fluid and excess fluid flows outwardly through a second lumen of the dual-lumen catheter, from which it is collected. Methods and kits provide for collection of fluid and cells by a lavage procedure that includes applying external pressure to the breast to improve the yield of fluid and cells from the breast duct.

US Patent:

8548571, Oct 1, 2013
Filed:

Dec 8, 2010
Appl. No.:

12/963536
Inventors:

Xuanmin He - Sunnyvale CA, US
John B. Simpson - Woodside CA, US
Michael H. Rosenthal - San Carlos CA, US
John F. Black - San Mateo CA, US
Assignee:

Avinger, Inc. - Redwood City CA
International Classification:

A61B 1/07
A61B 6/00
US Classification:

600476, 600425
Abstract:

The present invention relates to methods and devices for predicting restenosis, and for treating atherosclerosis to prevent or reduce the incidence of restenosis. Methods of predicting restenosis in a stenosed peripheral artery may include quantitative histology of the vessel. For example, a method of treating a stenosed artery (and particularly a peripheral artery) may include the steps of determining a level of hypercellularity and one or more of the lipid-richness and extent of inflammatory cell inclusion in the tissue. An index of restenosis based on the hypercellularity and lipid richness and/or extent of inflammatory cell inclusion in the tissue may be determined. Systems for treating or preventing restenosis may include one or more imaging modalities for imaging tissue regions and determining the level of hypercellularity and one or more of the degree of lipid-richness and the extent of inflammatory cell inclusion in the tissue region.

US Patent:

20020002343, Jan 3, 2002
Filed:

Jul 19, 2001
Appl. No.:

09/907581
Inventors:

David Hung - Belmont CA, US
Christopher Ken - San Mateo CA, US
Xuanmin He - Palo Alto CA, US
Phillip Olsen - Mountain View CA, US
Julian Nikolchev - Portola Valley CA, US
Shawn O'Leary - San Jose CA, US
Pam Sayavong - Newark CA, US
International Classification:

A61B005/00
US Classification:

600/573000
Abstract:

The invention provides methods, devices and systems for collecting breast ductal fluid comprising cellular material and other useful markers for analysis. The methods typically comprise access of at least one breast duct and collecting materials from that duct separate from all other ducts in the breast. The devices comprise ductal access devices that provide the opportunity to collect fluid from a single duct separate from all the other ducts in the breast. The systems employ the methods and devices that used together provide systems for analysis of a breast condition in a patient specific to accessed breast ducts. The methods, devices and systems are particularly useful for indentification of breast precancer or cancer in patient.
