US Patent 12011555 Guidewire with core centering mechanism

The present disclosure relates to guidewire devices with an outer tube and a core. The distal section of the core extends into and is surrounded by the outer tube. One or more centering mechanisms are also disposed within the outer tube and are arranged to fill a portion of the annular space between the core and the inner surface of the tube. The one or more centering mechanisms thereby assist in keeping the distal section of the core axially aligned within the tube, which enables effective control of the device and minimizes undesirable whip movements of the guidewire.
