Abstract: A system for measuring a pressure in a vein includes a needle sized and shaped to be inserted through a working channel of an endoscope. The needle is extending longitudinally and including a channel extending longitudinally therethrough. The system also includes a pressure sensing device including a longitudinally extending body sized and shaped to be slidably inserted through the channel of the needle and a sensor mounted on a distal portion of the body and connected to a proximal portion of the pressure sensing device via a connection cable. The sensor is configured to detect information corresponding to a pressure of a flow of blood through a vein.

Abstract: Pressure sensing guidewires and methods for making and using pressure sensing guidewires are disclosed. An example pressure sensing guidewire may include a tubular member having a proximal region and a housing region. An optical fiber may be disposed within the tubular member and extend to the housing region. The optical fiber may have a distal end region with a cavity formed therein. A polymeric member disposed within the cavity. A reflective surface disposed along the polymeric member.

Abstract: Pressure sensing guidewires and methods for making and using pressure sensing guidewires are disclosed. An example pressure sensing guidewire may include a tubular member having a proximal region and a housing region. An optical pressure sensor may be disposed within the housing region. The optical pressure sensor may include a sensor body and a deflectable membrane coupled to the sensor body. The deflectable membrane may include a polymer. An optical fiber may be coupled to the sensor body and may extend proximally therefrom. A pressure equalization channel is formed in the optical fiber, the sensor body, or both.
