USPTO Patent Grants: Fluid Flow Rate in Phacoemulsification Probe
Summary
The USPTO has granted patent US12582550B2 to Johnson & Johnson Surgical Vision, Inc. for an apparatus determining fluid flow rate in a phacoemulsification probe. The patent details a method using pressure sensors and a processor to calculate flow rate, aiming to improve surgical procedures.
What changed
The United States Patent and Trademark Office (USPTO) has granted patent US12582550B2, assigned to Johnson & Johnson Surgical Vision, Inc. The patent covers an apparatus and method for determining fluid flow rate within a phacoemulsification probe, a critical component in ophthalmic surgery. The invention utilizes two pressure sensors at a preset distance and a processor to calculate the fluid's travel time, thereby determining the flow rate. This technology is intended to enhance the precision and control of surgical procedures.
This patent grant is primarily an intellectual property matter and does not impose new regulatory obligations on medical device manufacturers or healthcare providers. However, companies involved in the development or manufacturing of phacoemulsification probes, particularly those using similar technologies, should be aware of this granted patent to ensure compliance with intellectual property laws and avoid potential infringement. The effective date of the patent grant is March 24, 2026.

Abstract
Apparatus for determining a fluid flow rate in a channel of a phacoemulsification probe, including a first pressure sensor, coupled with fluid in the channel at a first position. A second pressure sensor couples with the fluid in the channel at a second position, at a preset distance from the first position, and the fluid flows from the first to the second position. A processor acquires from the first pressure sensor first indications of a pressure profile of a portion of the fluid passing the first pressure sensor, and acquires from the second pressure sensor second indications of a pressure profile of the fluid passing the second pressure sensor. The processor correlates the first and second indications to determine a time for the fluid portion to travel from the first to the second position, and calculates the fluid flow rate in response to the time and the preset distance.
