US Patent:

61969664, Mar 6, 2001

Filed:

Dec 30, 1998

Appl. No.:

9/222007

Inventors:

John Kerin - North Adelaide, AU
Charles Milo - Santa Barbara CA
Julian N. Nikolchev - Portola Valley CA
James Doty - Larkspur CA
Dai T. Ton - San Jose CA

Assignee:

Conceptus, Inc. - San Carlos CA

International Classification:

A61B 101
A61B 1303

US Classification:

600114

Abstract:

A method and apparatus are provided for imaging a narrow body lumen, the method comprising maintaining separation between a distal end of an optical viewing scope and a lumen wall with a spacing structure which extends distally from the distal end of an access catheter. Optional spacing structures include distal cages and a guidewire which is fixed to and extends distally from the access catheter body. The invention is beneficial during either retrograde imaging of the fallopian tube, and also allows antigrade imaging and advancing the access catheter and scope under the direction of the image provided, as it prevents the tubal wall from coming into such close proximity to a falloposcope as to produce "white-out" on the imaging monitor.

International Classification:

A61F 2/958

Abstract:

A stent crimping tool insert comprises a core body configured for insertion into and removal from within a crimping chamber of a stent crimping tool. The core body has a core surface configured to withstand a compressive force without a reduction in diameter of the core surface.
