A pressure sensor configured for biological pressure measurement at a distal end portion of an elongated member comprises a dissolvable hydrophilic material coated on a surface of the pressure sensor. A guide wire for biological pressure measurement may include a tube extending along a longitudinal axis of the guide wire; and a pressure sensor for biological pressure measurement, at least a portion of the pressure sensor being mounted within the tube. The pressure sensor comprises a pressure sensor membrane facing a top side of the tube. A circumferential wall of the tube includes at least six openings: a first distal opening, a second distal opening located on a right side of the tube, a third distal opening located on a left side of the tube, a first proximal opening, a second proximal opening located on a right side of the tube, and a third proximal opening located on a left side of the tube. The first distal opening is larger than the second and third distal openings, and the first proximal opening is larger than the second and third proximal openings.

A sensor guide wire assembly having a button-cell type battery includes a transmitter unit configured to be connected to a sensor guide wire that is insertable into a patient to measure a parameter, the transmitter unit being configured to wirelessly transfer data representing the measured parameter to a communication unit. The transmitter unit includes a housing, a printed circuit board holder disposed in the housing, and a printed circuit board disposed in the housing and held by the printed circuit board holder. The printed circuit board includes a plurality of electrical contacts. A slider is slidable from a location outside the housing, the slider including a protrusion extending into an area inside the housing. A space within the housing is configured to hold one or more batteries. The slider is slidable from a first position, at which a micro-switch is not activated, to a second position, at which the micro-switch is activated by the protrusion of the slider, which allows power to be provided to the printed circuit board.

Sensor guide wire assembly with button-cell type battery

Sensor guide wire for intravascular measurements of physiological variables in a living body or of external signals, which sensor guide wire has a proximal region, a distal sensor region and a tip region, the sensor guide wire comprises a core wire having a longitudinal axis parallel to the longitudinal axis of the sensor guide wire, and a sensor element arranged in the distal sensor region, the sensor element has a sensitive portion for measuring the physiological variable and to generate a sensor signal in response to said variable. The sensor element has an essentially planar main surface and has its maximal extension in the plane of the main surface, and a thickness perpendicular to the plane of the main surface, wherein the sensor element is arranged in an essentially perpendicular relation to said core wire with regard to the planar main surface of the sensor element.
