  • Patent number: 11336212
    Abstract: An electromechanical stator includes an actuator section, a support section and a spring section. A continuous sheet of elastic material constitutes at least a part of each of these sections. The actuator section includes a vibration body and a moved-body interaction portion. The vibration body includes an electromechanical volume. The spring section is elastic, with a spring constant, enabling provision of a normal force in the vibration direction upon displacement of the fixation point. Also an electromechanical motor and a method of operating such an electromechanical motor are disclosed.

  • Publication number: 20190282170
    Abstract: A guidewire for a medical device is disclosed. The guidewire includes an elongate body, a proximal connector assembly, a corewire, and a sensor assembly. The body has an annular wall that defines an interior lumen. The proximal connector assembly is coupled to the body and is configured for connection to a medical positioning system. The corewire extends through the lumen. The sensor assembly located on a distal end of the corewire is electrically connected to the proximal connector assembly. The sensor assembly is configured to generate an electrical signal indicative of a position of the sensor assembly in a reference coordinate system defined by the medical positioning system. The body includes a helical cutout extending over a predetermined length of the body. The helical cutout is configured to increase the flexibility of the body over the predetermined length of the body.

    Abstract: A sensor guide wire for an intravascular measurement of a physiological variable in a living body may include a sensor element configured to measure the physiological variable based on exposure to fluid in the living body; and a cylindrical-shaped jacket forming an interior space housing the sensor element. The jacket comprises an outer circumferential wall with a circumferential surface extending between distal and proximal longitudinal ends of the jacket. The outer circumferential wall of the jacket does not include any apertures along its circumferential surface so as to prevent fluid from passing through the outer circumferential wall and/or the jacket has a constant cross section along its entire length.

  • Patent number: 8323215
    Abstract: During use there is a risk that a male connector for a guide wire is bent. With the present male connector (1) more material with high modulus of elasticity can be provided inside the male connector (1), which makes the male connector (1) more bending resistant. The male connector (1) comprises a core wire (3), a plurality of conductive members (4) spaced apart longitudinally along said core wire (3), a plurality of conductors (5) disposed along the core wire (3), each of the conductors (5) being connected to a respective conductive member (4). The core wire (3) has such a shape that least one longitudinal cavity is provided, which longitudinal cavity remains substantially intact when the male connector (1) is bent, thereby protecting the conductors (5), which are disposed in said cavity, from being damaged.

  • Patent number: 6561036
    Abstract: Pressure sensor for measurement of gas pressure in a cylinder of a combustion engine, including a tube shaped in cross section as an hourglass. In the axial direction the tube consists in part of a section connected to the cylinder and open to the cylinder, in part of a measuring section and in part of a final section the end of which is closed. The measuring section of the tube is shaped so that in the tubes axial direction two parallel measuring surfaces are established against which are two beams connected to force transferring yokes arranged to influence force measuring organs for the determination of the force with which the gas pressure influences the parallel measuring surfaces of the tube. In this pressure sensor and other embodiments the influences of temperature fluctuations and any shunting effects of the material of the measuring tube are reduced to a minimum.
