US Patent:

7814915, Oct 19, 2010

Filed:

Mar 2, 2007

Appl. No.:

11/681700

Inventors:

Scott A. Davenport - Half Moon Bay CA, US
David A. Gollnick - San Francisco CA, US
Steven Christensen - Fremont CA, US
Dean A. MacFarland - Magnolia MA, US
Robert Bernhard Estrada - San Carlos CA, US

Assignee:

Cutera, Inc. - Brisbane CA

International Classification:

A61B 19/00
A61B 18/20

US Classification:

128898, 606 3, 606 9, 607 89

Abstract:

A dermatological treatment method includes directing laser energy having a wavelength of 2. 79 μm onto skin. According to disclosed methods, the energy can function to ablate a first portion of epidermal tissue, coagulate an underlying second portion of epidermal tissue, and promote collagen formation in tissue of the underlying dermis. In an exemplary treatment apparatus, a laser using a YSGG gain medium is mounted in a handpiece. The handpiece may include a two-axis scanner to allow for uniform scanning of the energy over the tissue surface.

Appl. No.:

7/841426

Inventors:

Robert B. Estrada - Redwood City CA
David Trost - San Francisco CA

Assignee:

Coherent, Inc. - Palo Alto CA

International Classification:

A61B 1736

US Classification:

606 18

Abstract:

An improved apparatus for manually manipulating a surgical laser beam is disclosed. The preferred embodiment of the invention includes a mirror nominally positioned at a 45 degree angle to the incident laser beam, a joy stick for manipulating the mirror, and a linkage interconnecting the two. The mirror is mounted to allow it to rotate about two mutually perpendicular and intersecting axes. The linkage operates to direct the reflected laser beam in two orthogonal dimensions such that a ratio between the movement of the reflected beam in each dimension is equivalent to the ratio of the movement of the joy stick in each dimension. This yields a reflected laser beam that moves a distance proportional to the amount of motion input to the joy stick. The reduction or amplification ratio between the input motion and the reflected laser beam motion remains constant, regardless of the direction of motion. In this manner, by moving the joy stick in a circular motion, the reflected laser beam also moves in a circular motion, rather than in an elliptical motion.
