  • Patent number: 11864781
    Abstract: A device for removing a clot from a vessel can have dual layers where an inner expandable body runs within an outer expandable body. The device can have a collapsed delivery configuration, an expanded deployed configuration, and a clot pinching configuration. The inner and outer bodies can be a plurality of cells formed by a network of struts. The openings of the cells align when the device is deployed within the clot, where the radial force from the expanding bodies urges portions of the clot through the openings. The inner and outer bodies can be configured to be selectively translatable relative to each other, so that the portions of the clot in the cell openings can be compressed and gripped when the translation transitions the device to the clot pinching configuration. The translation can be maintained to pinch the clot as it is retrieved from the patient.

  • Publication number: 20230364319
    Abstract: An aspiration catheter for assisting in the retrieval of a clot from a vessel of a patient including at least one electrode pair and a first pressure sensor positioned within an inner lumen of the aspiration catheter and a second and third pressure sensor positioned on an exterior surface of the aspiration catheter. The electrode pair and pressure sensors are in electrical communication with a control console. The control console is configured to modulate an aspiration vacuum pressure waveform pattern applied through the aspiration catheter based on electrical and pressure inputs from the one or more sensors, and optionally based on a blood pressure waveform pattern of the patient.

  • Publication number: 20140142419
    Abstract: A method includes receiving a position of an intra-body probe inserted into an organ of a living body in a first coordinate system. Fluoroscopic images of the body are received. A movement of the body in the fluoroscopic images is measured in a second coordinate system. The received position of the intra-body probe in the first coordinate system is corrected using the movement identified in the second coordinate system.

  • Patent number: 8180430
    Abstract: A method for position tracking includes using first and second field generators located at respective different first and second locations to generate respective first and second magnetic fields in a vicinity of first and second objects. The first and second fields are measured using first and second position sensors respectively associated with the first and second objects. First and second potential relative coordinates of the first object relative to the second object are calculated responsively to the first and second magnetic field. The potential relative coordinates are processed in order to determine a correct relative coordinate of the first object relative to the second object.

  • Patent number: 8046050
    Abstract: A surgical tracking system includes a wireless position sensor, which is adapted to be implanted in a bone of a subject, and responsively to externally-applied magnetic fields within a working volume of the tracking system, to generate and transmit sensor signals indicative of coordinates of the position sensor within the bone. A plurality of field generator coils are adapted to generate the magnetic fields so as to define the working volume. The field generators are fixed in predetermined locations to a reference structure, which is movable relative to the subject in order to position the working volume so as to intercept the bone. A system controller is coupled to receive and process the sensor signals so as to determine the coordinates of the position sensor within the bone.
