Dual-Tip Catheter System For Boring Through Blocked Vascular Passages

View page
US Patent:
20100125253, May 20, 2010
Filed:
Nov 17, 2008
Appl. No.:
12/272697
Inventors:
William John Olson - Menlo Park CA, US
Charles McNall - Belmont CA, US
Assignee:
Avinger - Santa Clara CA
International Classification:
A61M 25/01
A61B 17/22
US Classification:
604267, 606159
Abstract:
A dual-tip catheter equipped with both a rotating cutting bit and a cavity for a probing guidewire tip for passage through chronic total occlusions or other refractory atherosclerotic plaque from diseased arteries. The catheter's guidewire tip and rotating cutting bit reside safely within an outer protective catheter sheath head when not in use, and alternately either the cutting bit or the guidewire tip will protrude out of the same distal opening of the sheath head as needed. By first drilling through refractory occlusions, and then inserting a guidewire tip into the occlusion opening formed by the cutting bit, the catheter can force the guidewire tip past the occlusion. After the guidewire tip has been fully inserted, the dual-tip catheter can be withdrawn, and an alternate catheter inserted and directed up the guidewire to the occlusion site, where the alternate catheter can perform further occlusion enlargement or therapeutic activity.

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.

Atherectomy Catheter With Laterally-Displaceable Tip

View page
US Patent:
20110004107, Jan 6, 2011
Filed:
Jul 1, 2010
Appl. No.:
12/829277
Inventors:
Michael H. Rosenthal - San Carlos CA, US
Michael Zung - San Carlos CA, US
Nicholas J. Spinelli - San Mateo CA, US
Charles W. McNall - Belmont CA, US
John B. Simpson - Woodside CA, US
John F. Black - San Mateo CA, US
International Classification:
A61B 17/22
A61B 6/00
US Classification:
600479, 606159
Abstract:
Described herein are atherectomy catheters, systems and methods that include a distal tip region that may be moved laterally so that its long axis is parallel with the long axis of the main catheter body axis. Displacing the distal tip region laterally out of the main catheter body axis exposes an annular blade and opens a passageway for cut tissue to enter a storage region within the catheter. The annular blade may be internally coupled to a drive shaft that rotates the blade, and thus the exposed blade edge may have the same crossing profile (OD) as the rest of the distal end region of the catheter. Also described herein are gear-driven atherectomy devices that may use a cable drive shaft to actuate the annular blade. Both push-to-cut and pull-to-cut variations are described, as are methods for cutting tissue and systems including these atherectomy catheters.

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.

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.

US Patent:
20140038495, Feb 6, 2014
Filed:
Mar 15, 2013
Appl. No.:
13/844433
Inventors:
Charles W. McNall - Cedar Hills UT, US
International Classification:
A63B 47/00
B24B 11/06
US Classification:
451 50, 451294, 451119, 451259, 451159
Abstract:
A method and system for resurfacing one or more lacrosse balls is provided. The system includes a container, a rotatable member, and a motor. The container is configured to hold the one or more lacrosse balls. The rotatable member includes an abrasive surface configured to scuff the lacrosse balls while in the container, The motor includes a drive shaft coupled to the rotatable member and configured to facilitate rotation of the rotatable member. With this arrangement, the lacrosse balls are positioned over the abrasive surface such that, upon rotation of the rotatable member the abrasive surface scuffs the lacrosse balls to, thereby, resurface the balls.
