Filed:

Nov 24, 2009

Appl. No.:

12/625335

Inventors:

Kathleen McMillan - Concord MA, US
Anurag Gupta - Tucson AZ, US

Assignee:

Gradiant Research, LLC - Concord MA

International Classification:

A61B 18/22
A61B 18/20

US Classification:

606 16, 606 13, 606 18

Abstract:

An apparatus and a method are provided for the treatment of soft tissue. The apparatus includes a light source and at least two optical assemblies. Each of the optical assemblies includes at least one optical element and a light-transmitting contact surface configured to transmit a substantially uniform distribution of light therethrough. The apparatus further includes at least two optical transmission devices each disposed between the light source and a corresponding one of the at least two optical assemblies. The apparatus also includes a handpiece to which the at least two optical assemblies are attached, and which is adapted to bring the light-transmitting contact surfaces of the at least two optical assemblies in contact with soft tissue disposed therebetween. The method includes compressing and substantially flattening portions of the tonsil tissue between light-transmitting contact surfaces of two opposed light emitting optical assemblies, introducing light into an optical element of each of the optical assemblies; and irradiating the tonsil tissue by directing the light from the optical element through the light-transmitting contact surfaces to the tonsil tissue in a substantially uniform light distribution.

Appl. No.:

12/952946

Inventors:

Kathleen McMillan - Concord MA, US
Anurag Gupta - Tucson AZ, US

International Classification:

A61B 18/22

US Classification:

606 16

Abstract:

Disclosed herein are optical assemblies having thin, low profile shapes. These optical assemblies may be used with fiber coupled lasers and other light sources, including high power sources, to irradiate tissue at a wavelength suitable for inducing ablation or coagulation to a target depth, denaturation, thermal modification of a tissue, and/or preferential injury to a target tissue structure. Example optical assemblies can produce substantially uniform illumination patterns that are useful for treating superficial tissue, including the internal or luminal (e.g., esophageal) tissue. Some examples may have capability for cooling superficial tissue or skin, such as a detachable, reusable heat sink for active cooling without consumables, fluid pumps, or other cooling equipment.

International Classification:

G01N 21/75
G01N 33/49

US Classification:

422 8209, 356 41

Abstract:

An analyte meter for an analyte test strip includes a light source configured to emit a light having a wavelength substantially similar to the maximum absorption band of Hb, an optics assembly configured to direct the light emitted by the light source to a test strip, and a photodetector configured to quantitatively detect light emanating from the test strip and to generate a signal correlating to an analyte concentration in the test strip.

International Classification:

H05K 7/20

US Classification:

165 801

Abstract:

A cold chassis and method of making a cold chassis for electronic modules featuring the fabrication of individual brazed cooling ribs each including microchannels along the length thereof and a peripheral flange. A set of adjacent ribs are secured together and assembled onto at least one face of a frame member. The rib flanges are sealed (e.g., friction stir welded) with respect to the frame member.
