  • Publication number: 20240017040
    Abstract: A catheter accessory for use with a catheter having a distal portion comprising an intervention accessory having a distal portion outer diameter. The catheter accessory comprises an elongated tubular structure, releasably mounted onto the intermediate portion, but static during operation, to provide a pre-determined flexural rigidity and a pre-determined flexibility simultaneously to the intermediate portion covered by the elongated tubular structure. The elongated tubular structure has a default shape and size for operation with a lumen with an inside diameter larger than the intermediate portion outer diameter and smaller than the distal portion outer diameter, holding the catheter accessory onto the intermediate portion and completely proximal to the distal portion comprising the intervention accessory during the operation.

  • Patent number: 11632169
    Abstract: The method relates to a synchronization of a magnetic locating system including a first device and a second device each including an oscillator, a time counter clocked by the oscillator, and a radiocommunication module. The locating system also includes a device for emitting and receiving alternating magnetic fields, the device being configured to allow a propagation of alternating magnetic fields between the first and second devices, the device for emitting and receiving alternating magnetic fields being connected to the oscillators of the first and second devices. The synchronizing method includes a synchronizing step that is configured to synchronize the oscillators of the first and second devices by adjusting, by servo-controlling the oscillator of the second device, the operation of the time counter of the second device to the operation of the time counter of the first device.

  • Publication number: 20220233201
    Abstract: There is described a device for applying an adjustable and simultaneous compression on vessel access points. The device comprises a frame comprising a body with at least two cavities through the body to be placed about surfaces of a patient corresponding to the at least two cavities. At least two compression members are movably fitted in the cavities, wherein a portion of the frame defines a space into which a portion of the compression member is fitted and around which it hinges. A side of the compression members opposite a portion around which it hinges comprises a locking mechanism which releasably engages with the frame at an interface between said side and the frame to lock each one of the at least two compression members in a given hinge position for applying the pressure onto the vessel access point depending on the hinge position.

  • Patent number: 10371764
    Abstract: An optical pumping and isotropic measurement magnetometer. The magnetometer is all-optical in the sense that resonance between Zeeman sub-levels is induced by modulating the intensity or the frequency of the pump beam. Resonance is detected either using the pump beam itself or an unmodulated probe beam. The pump beam is linearly polarised and its polarisation direction is kept constant relative to the direction of the magnetic field to be measured, so that a measurement independent of the orientation of the field can be made.
