Magnetically Couplable Fiducial Marker Arrays for Surgical Navigation
Summary
USPTO published patent application US20260090861A1 for a magnetically couplable fiducial marker array designed for surgical navigation. The invention includes a rigid body supporting multiple surgical fiducial markers in an asymmetrical fixed arrangement, with a magnetic coupling mechanism for attachment to a surgical spinous process clamp. Inventors include Jesse Harrison Gallant, Osamah Choudhry, Christopher Morley, and Florentin Jonas Liebmann.
What changed
The patent application discloses a magnetically couplable fiducial marker array comprising a rigid body configured to support a plurality of surgical fiducial markers at fixed positions relative to each other. The key innovation is that the fixed positional arrangement of surgical fiducial markers is asymmetrical, which enables more precise surgical navigation. The magnetic coupling arrangement incorporates array magnetic components configured to form a magnetic coupling with separate magnetic components of a surgical spinous process clamp at a fixed position relative to the clamp.
Medical device manufacturers developing surgical navigation systems or spinal surgical tools should review this application for potential prior art implications or licensing opportunities. The technology applies to CPC classifications A61B 90/39 and A61B 17/00, indicating relevance to surgical instruments and markers. Patent application 19344170 was filed on September 29, 2025. No regulatory compliance actions are required from this document.

Abstract
A magnetically couplable fiducial marker array can include a rigid body, a plurality of surgical fiducial markers, and a magnetic coupling arrangement. The rigid body can be configured to support the plurality of surgical fiducial markers at fixed positions relative to each other along the rigid body to form a fixed positional arrangement of surgical fiducial markers. At least a support portion of the rigid body can be arranged along a surgical fiducial marker support plane and the fixed positional arrangement of surgical fiducial markers can be asymmetrical. The magnetic coupling arrangement can be formed at the rigid body with array magnetic components and can be configured to form a magnetic coupling between the array magnetic components and separate magnetic components of a separate surgical spinous process clamp at a first fixed position relative to the separate surgical spinous process clamp.
