Patent number: 12290323Abstract: A single-sided magnet and magnetic resonance imaging (“MRI”) system are portable and lightweight, enabling use as a point-of care (“POC”) MRI device. The portable MRI system includes a magnet assembly containing layers of magnet blocks, such as rare-earth magnet blocks. The magnet blocks are arranged in concentric rings in each layer, and surround a central aperture extending through the magnet assembly. The central aperture is sized to allow a medical instrument, such as a needle, to pass through the central aperture. The portable MRI system can therefore be used for image guidance in lumbar puncture (“LP”) and other medical procedures.Type: GrantFiled: April 26, 2021Date of Patent: May 6, 2025Assignee: The General Hospital CorporationInventors: Lawrence L.

Patent number: 12263032Abstract: An apparatus and method for estimating one or more hemodynamic parameters such as cardiac output or stroke volume. Embodiments are based on the concept of incorporating information about vascular tone into hemodynamic parameter estimation to improve accuracy.

Patent number: 12256952Abstract: The present invention relates to a system for the controlled fragmentation of solids by means of acoustic beams, comprising at least one acoustic beam generation unit (100); and one feedback and control unit (200) of said generation unit (100). Advantageously, the acoustic beams generated by the system are acoustic vortex beams; and the feedback and control unit (200) further comprises a feedback subsystem (12), configured to receive the information relating to the fragmented solids and to utilize it so as to adapt the operation of the acoustic beam generation unit (100). Given that the generation of shearing stresses is more efficient using vortex beams, the amplitudes of the ultrasonic field needed to fragment the calculi are much lower than in current extracorporeal shock wave lithotripsy techniques. Likewise, the system minimizes unwanted effects on soft tissues surrounding the solid.Type: GrantFiled: July 15, 2021Date of Patent: March 25, 2025Assignees: UNIVERSITAT POLITÈCNICA DE VALÈNCIA, CONSEJO SUPERIOR DE INVESTIGACIONES CIENTÍFICAS (CSIC)Inventors: Noé Jiménez González, Francisco Camarena Femenia, Jose María Benlloch Baviera
