Alignment techniques for percutaneous access

This invention describes a system that helps surgeons precisely guide a medical instrument to a target location within a patient's organ. It works by tracking the instrument's position and direction, then calculating a dynamic plane that includes the target and remains perpendicular to the instrument's heading. The system then generates visual guidance data, showing the surgeon how to align the instrument's projected path with the target on this plane.

Why it matters: Filed before significant advancements in real-time surgical tracking sensors and augmented reality displays. These improvements could now make the precise guidance data more accurate and intuitively presented to surgeons.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMedical sensors, software logic, display system
