Optical Ultrasound Receiver

US Patent:
8560048, Oct 15, 2013
Filed:
Oct 1, 2009
Appl. No.:
12/571724
Inventors:
Michael J. Eberle - Fair Oaks CA, US
Diana Margaret Tasker - Fair Oaks CA, US
Howard Neil Rourke - Sacramento CA, US
Assignee:
Vascular Imaging Corporation - Ranchero Cordova CA
International Classification:
A61B 5/05
US Classification:
600407, 600437, 600459, 600472, 600473, 600476, 600477
Abstract:
An imaging guidewire can include one or more optical fibers communicating light along the guidewire. At or near its distal end, one or more blazed or other Fiber Bragg Gratings (FBGs) can direct light to a photoacoustic transducer material that provides ultrasonic imaging energy. Returned ultrasound can be sensed by an FBG sensor. A responsive signal can be optically communicated to the proximal end of the guidewire, and processed such as to develop a 2D or 3D image. In an example, the guidewire outer diameter can be small enough such that an intravascular catheter can be passed over the guidewire. To minimize the size of the guidewire, an ultrasound-to-acoustic transducer that is relatively insensitive to the polarization of the optical sensing signal can be used. The ultrasound-to-optical transducer can be manufactured so that it is relatively insensitive to the polarization of the optical sensing signal.

US Patent:
20130317372, Nov 28, 2013
Filed:
May 24, 2013
Appl. No.:
13/902334
Inventors:
Michael J. Eberle - Fair Oaks CA, US
Diana Margaret Tasker - Fair Oaks CA, US
Howard Neil Rourke - Sacramento CA, US
Assignee:
Vascular Imaging Corporation - Rancho Cordova CA
International Classification:
A61B 5/0215
A61B 5/00
US Classification:
600478
Abstract:
In an example, this document discloses an apparatus for insertion into a body lumen, the apparatus comprising an optical fiber pressure sensor. The optical fiber pressure sensor comprises an optical fiber configured to transmit an optical sensing signal, a temperature compensated Fiber Bragg Grating (FBG) interferometer in optical communication with the optical fiber, the FBG interferometer configured to receive a pressure and modulate, in response to the received pressure, the optical sensing signal, and a sensor membrane in physical communication with the FBG interferometer, the membrane configured to transmit the received pressure to the FBG interferometer.

US Patent:
20210223470, Jul 22, 2021
Filed:
Mar 24, 2021
Appl. No.:
17/210718
Inventors:
- Folsom CA, US
Michael J. Eberle - Fair Oaks CA, US
Howard Neil Rourke - Sacramento CA, US
International Classification:
G02B 6/06
G02B 6/38
G02B 6/44
G01H 9/00
G02B 6/02
G02B 6/40
Abstract:
An intravascular or other 2D or 3D imaging apparatus can include a minimally-invasive distal imaging guidewire portion. A plurality of thin optical fibers can be circumferentially distributed about a cylindrical guidewire core, such as in an spiral-wound or otherwise attached optical fiber ribbon. A low refractive index coating, high numerical aperture (NA) fiber, or other technique can be used to overcome challenges of using extremely thin optical fibers. Coating and ribbonizing techniques are described. Also described are non-uniform refractive index peak amplitudes or wavelengths techniques for FBG writing, using a depressed index optical cladding, chirping, a self-aligned connector, optical fiber routing and alignment techniques for a system connector, and an adapter for connecting to standard optical fiber coupling connectors.

Appl. No.:
16/707298
Inventors:
- Rancho Cordova CA, US
Diana Margaret Tasker - Bluff Lane CA, US
Howard Neil Rourke - Sacramento CA, US
David J. Spamer - Granite Bay CA, US
International Classification:
A61B 5/0215
Abstract:
The disclosure includes an apparatus including an elongated assembly, at least a portion of which is sized, shaped, or otherwise configured to be inserted into a human body to measure a physiological parameter at an internal location within the body. The elongated assembly includes an elongated member having a first length and an outer surface, a coil disposed about at least a portion of the elongated member, the coil having a second length, and at least one stand-off member positioned between the outer surface of the elongated member and the coil, where the at least one member is configured to prevent the coil from contacting an optical fiber positioned between the elongated member and the coil.
