Appl. No.:

12/757793

Inventors:

Robert Hitchcock - Scotts Valley CA, US
James Kingman - Woodside CA, US
Matthew Weaver - Scotts Valley CA, US
Dustin Cochran - Scotts Valley CA, US
Sanjoy Ghose - Scotts Valley CA, US

Assignee:

Lumenetix, Inc. - Scotts Valley CA

International Classification:

F21V 5/00
F21V 29/00
G02B 21/26

US Classification:

362580, 362547, 362218, 362264, 362294, 362345, 362373

Abstract:

A lighting system is described. The lighting system includes a lamp and a first container including a first phase change material thermally connected to the lamp. Heat generated by the lamp during operation is conducted to the first phase change material. The system also includes a second container including a second phase change material thermally connected to the lamp. Heat generated by the lamp during operation is also conducted to the second phase change material, and the second phase change material has a transition point temperature lower than the transition point temperature of the first phase change material of the first container to account for a temperature drop between the second container and the first container. The lighting system also includes a temperature sensor for reducing lamp power if the lamp becomes too hot, and a mounting bracket which may also conduct heat away from the lamp.

Appl. No.:

17/527456

Inventors:

- Campbell CA, US
Robert Hitchcock - Los Gatos CA, US
Kyle Bartholomew - Campbell CA, US
David Gonzalez - Campbell CA, US

International Classification:

A61B 34/30
A61B 17/22
A61M 25/01
A61M 25/00

Abstract:

A method of performing a neurovascular procedure includes the steps of providing an access assembly comprising a guidewire, access catheter and guide catheter; coupling the access assembly to a robotic drive system; and driving the access assembly to achieve supra-aortic vessel access. The guide wire and the access catheter are decoupled from the access assembly. A procedure assembly includes at least a guidewire and a procedure catheter. The procedure assembly is coupled to the robotic drive system; and used to perform a neurovascular procedure.
