What changed
USPTO granted patent US12605216B2 to Acclarent, Inc. on April 21, 2026, for an apparatus comprising a body with a bore sized to receive a medical instrument having a rotary member configured to generate electromagnetic interference while rotating. The body is fixedly secured to the instrument while allowing rotation, and a position sensor supported by the body generates a signal indicating position in three-dimensional space while offsetting the electromagnetic interference generated by the rotary member.
Medical device manufacturers operating in the ENT or surgical navigation space should note this patent expansion in Acclarent's portfolio. While no compliance obligations arise from a patent grant itself, competitors developing similar rotary-member surgical instruments with integrated position sensing should review this patent for potential freedom-to-operate considerations.

Abstract
An apparatus includes a body and the first position sensor. The body defines a bore sized to receive a portion of a medical instrument having a rotary member. The rotary member is configured to generate interference in an electromagnetic field while rotating about a longitudinal axis. The body is configured to be fixedly secured to the medical instrument while allowing rotation of the rotary member about the longitudinal axis. The first position sensor is supported by the body and is configured to generate a signal indicating a position of the first position sensor in three-dimensional space. The first position sensor is oriented to offset the interference generated by the rotary member.
