    摘要： A sensor guide wire for intravascular measurement of a physiological variable includes: a core wire extending at least partly along a length of the sensor guide wire; a sensor element in a sensor region of the sensor guide wire; a jacket having a jacket wall, the jacket being fixed relative to the core wire; and at least one lead connected to the sensor element. The jacket is tubular and includes a proximal end opening, a distal end opening, and a first set of openings extending through the jacket wall. The first set of openings extending through the jacket wall includes a first opening located above the sensor element, a second opening located at a first lateral side of the sensor element, and a third opening located at a second lateral side of the sensor element, and wherein the first, second, and third openings are elongated in a longitudinal direction of the jacket, and are aligned in a circumferential direction of the jacket.

    摘要： 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.

    摘要： A sensor guide wire for intravascular measurements of at least one physiological or other variable in a living body, comprising a proximal region, a distal sensor region, and a tip region, and at least one sensor element arranged in said sensor region and configured to measure the variable and to generate a sensor signal in response to the variable. The sensor guide wire further comprises a core wire, with a tip core wire portion, wherein at least part of the tip core wire portion comprises a shape memory material, and the composition of the shape memory material is such that the transformation temperature of the shape memory material is above the body temperature of the living body.

    摘要： A measurement system may comprise a sensor wire and a transceiver unit. The sensor wire may comprise an insertable portion configured to be inserted in a blood vessel of a patient's body and two sensors disposed within the insertable portion at a distal end of the sensor wire. The sensors are configured to measure a parameter when inserted inside the patient. The transceiver unit may comprise: a housing adapted to be connected to a proximal end of the sensor wire; and a first communication module within the housing adapted to wirelessly communicate by a communication signal with an external second communication module in order to transfer information to the external second communication module.

    摘要： An eavesdropping arrangement for acquiring a measured physiological variable of an individual includes a receiver and a communication interface in a housing separate from the receiver. The communication interface is positioned along a communication link between a first sensor, which is configured to measure aortic blood pressure and to provide a signal representing measured aortic blood pressure, and a central monitoring device configured to monitor the measured aortic blood pressure. The communication interface includes a connection to the communication link that permits the communication interface to eavesdrop on the signal representing measured aortic blood pressure such that information representing measured aortic blood pressure is sent to the receiver while allowing the central monitoring device to receive and use the signal representing measured aortic blood pressure.
