Optical Coherence Tomography For Biological Imaging

View page
US Patent:
20100305452, Dec 2, 2010
Filed:
May 28, 2010
Appl. No.:
12/790703
Inventors:
John F. Black - San Mateo CA, US
Maegan K. Spencer - Mountain View CA, US
Michael Zung - San Carlos CA, US
Charles W. McNall - Belmont CA, US
Evangeline Lumabas - San Jose CA, US
Michael H. Rosenthal - San Carlos CA, US
John B. Simpson - Woodside CA, US
International Classification:
A61B 6/00
US Classification:
600476
Abstract:
Described herein are catheters for use with Optical Coherence Tomography (OCT) that include an optical fiber core having a first refractive index and an interface medium having a second refractive index, where the first and second refractive indexes are mismatched such that receiving electronics configured to receive optical radiation reflected from the reference interface and the target operate in a total noise range that is within 5 dB of the shot noise limit. These OCT catheters may include a silicon die mirror having a reflective coating that is embedded in the interface medium. The optical fiber can be fixed at just the distal end of the catheter, and may be managed within a handle that is attached to the proximal end of the catheter body, and is configured to allow rotation of the both catheter body and the optical fiber relative to the handle.

Catheter-Based Off-Axis Optical Coherence Tomography Imaging System

View page
US Patent:
20110021926, Jan 27, 2011
Filed:
Jul 1, 2010
Appl. No.:
12/829267
Inventors:
Maegan K. SPENCER - Mountain View CA, US
Christopher B. White - San Jose CA, US
Charles W. McNall - Belmont CA, US
Dennis W. Jackson - San Francisco CA, US
Michael Zung - San Carlos CA, US
Nicholas J. Spinelli - San Mateo CA, US
Benjamin Ngo - San Jose CA, US
Evangeline Lumabas - San Jose CA, US
Kin F. Chan - San Jose CA, US
John F. Black - San Mateo CA, US
Michael H. Rosenthal - San Carlos CA, US
John B. Simpson - Woodside CA, US
International Classification:
A61B 6/00
US Classification:
600478
Abstract:
Catheter-based Optical Coherence Tomography (OCT) systems utilizing an optical fiber that is positioned off-axis of the central longitudinal axis of the catheter have many advantage over catheter-based OCT systems, particularly those having centrally-positioned optical fibers or fibers that rotate independently of the elongate body of the catheter. An OCT system having an off-axis optical fiber for visualizing the inside of a body lumen may be rotated with the body of the elongate catheter, relative to a handle portion. The handle may include a fiber management pathway for the optical fiber that permits the off-axis optical fiber to rotate with the catheter body relative to the handle. The system may also include optical processing elements adapted to prepare and process the OCT image collected by the off-axis catheter systems described herein.

Atherectomy Catheters With Longitudinally Displaceable Drive Shafts

View page
US Patent:
20120046679, Feb 23, 2012
Filed:
Jul 1, 2011
Appl. No.:
13/175232
Inventors:
Himanshu N. Patel - San Jose CA, US
John B. Simpson - Woodside CA, US
Charles W. McNall - Belmont CA, US
Maegan K. Spencer - Mountain View CA, US
Michael Zung - San Carlos CA, US
International Classification:
A61B 17/22
US Classification:
606159
Abstract:
Described herein are atherectomy catheters, systems and methods that include longitudinally displaceable drive shafts that drive actuation of one or more cutters at the distal end of the catheter. The catheters described herein may include one or more imaging sensors for imaging before, during or after cutting tissue. In some variations the imaging sensor may be rotated around the perimeter of the catheter independently of the rotation of the cutter. Also describe herein are imaging catheters that may be used without cutters.

Atherectomy Catheters And Non-Contact Actuation Mechanism For Catheters

View page
US Patent:
20130096589, Apr 18, 2013
Filed:
Oct 17, 2012
Appl. No.:
13/654357
Inventors:
Maegan K. Spencer - Menlo Park CA, US
Nicholas J. Spinelli - San Mateo CA, US
International Classification:
A61B 17/3207
US Classification:
606159
Abstract:
An atherectomy catheter includes a deflectable distal tip, a rotatable cutter proximal to the distal tip, a cutter drive shaft configured to rotate the rotatable cutter, and a pull shaft concentric with the drive shaft and coupled to the distal tip. The pull shaft is configured such that pulling the pull shaft deflects the distal tip, thereby exposing the rotatable cutter. Also disclosed herein is a magnetic drive system configured for non-contact actuation of a catheter.

US Patent:
20130296695, Nov 7, 2013
Filed:
Jul 10, 2013
Appl. No.:
13/939161
Inventors:
Maegan K. SPENCER - Menlo Park CA, US

Michael H. ROSENTHAL - San Carlos CA, US
John B. SIMPSON - Woodside CA, US
International Classification:
A61B 5/00
US Classification:
600425
Abstract:
A system for imaging a body lumen includes a controller and a display. The controller is configured to connect to a proximal end of a catheter having an optical fiber extending along the length of an elongate catheter body. The controller is further configured to rotate a distal end of the optical fiber from a location near a proximal end of the elongate catheter body, acquire optical coherence tomography (OCT) images using the optical fiber as the distal end of the optical fiber rotates, and determine a rotational lag of the distal end of the optical fiber. The display is configured to display one or more OCT images corrected for the rotational lag.
