ViaLase Patent, Multistage Slide Mechanism, Medical Control
Summary
The USPTO granted Patent US12605280B2 to ViaLase, Inc. on April 21, 2026. The patent covers a medical system with a multistage slide mechanism featuring a coarse-float mechanism for head movement and a fine-float mechanism that reduces applied force in response to a triggering event corresponding to valid coupling between a cone attachment and patient interface. The patent includes 15 claims and was filed on November 23, 2022 under Application No. 17993596.
What changed
The USPTO granted a new patent to ViaLase, Inc. for a medical system incorporating a multistage slide mechanism with variable counterbalance to control head movement and force at an anatomical site. The mechanism includes a coarse-float component enabling head movement relative to a reference plane, and a fine-float component that limits applied force to an initial level and reduces it upon detecting valid coupling between the head's cone attachment and a patient interface. The patent is classified under CPC A61F 9/009 and A61B 2090/5025.
Medical device manufacturers developing slide mechanism or positioning systems for surgical or diagnostic medical equipment should review this patent for potential freedom-to-operate considerations. The patent's force-limiting mechanism triggered by interface coupling detection may represent a non-obvious advance in patient safety for laser or other precision medical systems requiring controlled force application.

Abstract
A medical system includes a head having an end arranged to face a reference plane and a multistage slide mechanism coupled with the head. The multistage slide mechanism includes a coarse-float mechanism configured to enable movement of the head relative to the reference plane, and a fine-float mechanism configured to limit a force applied through the head to an initial force, and to reduce the force applied through the head to a reduced force less than the initial force in response to a presence of a first triggering event. The first triggering event may correspond to a valid coupling between a cone attachment of the head and a patient interface coupled to an anatomical site at the reference plane.
