US Patent:

6763833, Jul 20, 2004
Filed:

Aug 22, 2000
Appl. No.:

09/644277
Inventors:

Ashish Khera - San Francisco CA
Don Gurskis - Redwood City CA
Dai Ton That - Milpitas CA
Betsy Swann - Newark CA
Steven Bacich - Half Moon Bay CA
Assignee:

Conceptus, Inc. - San Carlos CA
International Classification:

A61F 606
US Classification:

128830, 128831
Abstract:

Contraceptive methods, systems, and devices generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. A distal portion of the contraceptive device can function as a guidewire. The proximal portion may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues.

US Patent:

55514430, Sep 3, 1996
Filed:

Jan 21, 1995
Appl. No.:

8/379575
Inventors:

Ivan Sepetka - Redwood City CA
Phong Pham - San Jose CA
Dai T. That - San Jose CA
Julian Nikolchev - Portola Valley CA
Assignee:

Conceptus, Inc. - San Carlos CA
International Classification:

A61B 500
US Classification:

128772
Abstract:

The present invention sets forth a guidewire-type device which can be axially moved via application of axial force and/or by application of torquing force. The device is used for accessing regions within a body. The device is used to attach to subject material within a body, and, if desired, to remove the subject material. In particular, the device and method of the invention are advantageously utilized by health care practitioners for use in accessing tortuous and difficult body areas, such as fallopian tubes.

US Patent:

53911466, Feb 21, 1995
Filed:

Jun 24, 1993
Appl. No.:

8/084457
Inventors:

Dai T. That - San Jose CA
Robert Woodard - Fremont CA
Assignee:

Conceptus, Inc. - Fremont CA
International Classification:

A61M 3700
A61M 2500
US Classification:

604 95
Abstract:

A mechanism for manipulating the distal end of an elongate medical device, wherein steering is accomplished by a single wire which extends from the proximal to the distal end of the device, the wire being anchored at an eccentric location relative to the central axis of the device containing said steering mechanism. Advantageously, a device comprising the steering mechanism also comprises at least one through lumen extending substantially from the proximal to the distal end of the device whereby a device or materials can be moved to the distal end of the device.
