Patent number: 11696692Abstract: 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.Type: GrantFiled: December 9, 2019Date of Patent: July 11, 2023Assignee: Phyzhon Health Inc.Inventors: Michael J. Eberle, Diana Margaret Tasker, Howard Neil Rourke, David J. Spamer

Publication number: 20200093384Abstract: The disclosure includes an apparatus for insertion into a body lumen. The apparatus can comprise an optical fiber pressure sensor. The optical fiber pressure sensor can comprise an optical fiber configured to transmit an optical sensing signal. A temperature compensated Fiber Bragg Grating (FBG) interferometer can be in optical communication with the optical fiber. The FBG interferometer can be configured to receive a pressure and modulate, in response to the received pressure, the optical sensing signal. A compliant member such as a sensor membrane can be in physical communication with the FBG interferometer. The membrane configured to transmit the received pressure to the FBG interferometer.Type: ApplicationFiled: November 20, 2019Publication date: March 26, 2020Inventors: Michael J. Eberle, Diana Margaret Tasker, Howard Neil Rourke, David J. Spamer

Patent number: 10258240Abstract: In an example, an apparatus includes 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 can include an elongated member. The elongated assembly can include an optical fiber pressure sensor, located at a distal portion of the elongated member. The elongated assembly can include a housing disposed about the optical fiber pressure sensor. The elongated assembly can include a guidewire tube, coupled to the housing, the guidewire tube defining a receptacle sized and shaped to accept a guidewire to permit the distal portion of the elongated member to slide along the guidewire during insertion of the elongated assembly into the human body.Type: GrantFiled: November 23, 2015Date of Patent: April 16, 2019Assignee: Vascular Imaging CorporationInventors: Michael J.
