Filed:

Nov 21, 2008

Appl. No.:

12/313782

Inventors:

Amir Belson - Los Altos CA, US
James J. Leary - Fenton MO, US

Assignee:

Radguard, Inc. - Los Altos CA

International Classification:

H01J 35/16

US Classification:

378203

Abstract:

A radiation protection device attaches to the C-arm of a fluoroscope and shields and collimates the X-ray beam between the X-ray source and the patient and between the patient and the image intensifier. One embodiment has a radiation shield of X-ray opaque material that surrounds the C-arm of the fluoroscopy system, the X-ray source and the image intensifier. A padded slot fits around the patient's body. Another embodiment has conical or cylindrical radiation shields that extend between the X-ray source and the patient and between the patient and the image intensifier. The radiation shields have length adjustments and padded ends to fit the device to the patient. The radiation protection device may be motorized to advance and withdraw the radiation shields. A blanket-like radiation shield covers the patient in the area surrounding where the X-ray beam enters the body.

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

Apparatus and methods are described allow the techniques of endoscopic and laparoscopic surgery to be combined into a minimally invasive hybrid surgical technique called NOTES-assisted laparoscopic surgery. Manual and robotic-controlled versions of a modular laparoscopic tool are described having a small diameter shaft that is delivered laparoscopically to a surgical site. Larger diameter working tips are delivered through a NOTES delivery tube inserted to the surgical site through a natural orifice and joined to the shaft of the modular laparoscopic tool. Larger diameter working tips improve the effectiveness of the modular laparoscopic tools and the number and size of laparoscopic ports used can also be reduced.

Appl. No.:

7/422935

Inventors:

James J. Leary - Sunnyvale CA
John R. McKenzie - San Francisco CA

Assignee:

Cardiovascular Imaging Systems, Inc. - Sunnyvale CA

International Classification:

A61B 814

US Classification:

12866301

Abstract:

Intravascular catheters including both a flexible catheter body and a less flexible housing mounted at a distal end of the catheter body are provided with a flexible distal tip, preferably having a conical geometry. Guidewire channel or lumen is formed within the tip, and optionally additional guidewire lumens are formed in the housing or the distal end of the catheter body, or both. The catheters may thus be inserted and withdrawn over a guidewire without the need for the entire length of the catheter to pass over the guidewire.
