What changed

The United States Patent and Trademark Office (USPTO) has issued patent US12584578B2 for a "Torsional connector coupling assembly." This patent, assigned to CareFusion 303, Inc., details a coupler system designed for fluid pathways that can be rotated to align channels and openings, and which decouples when a force exceeding a specified threshold is applied. The filing date for this application was March 5, 2024.

This patent grant is primarily an intellectual property notification and does not impose new regulatory obligations on manufacturers. However, it signifies a new innovation in medical device connectors, potentially impacting competitors in the field. Companies developing similar coupling mechanisms should be aware of this granted patent and consider its implications for their product development and intellectual property strategies.

Abstract

A coupler including a first connector having a mating portion with a first opening, and a first torsion member disposed within the mating portion with a first channel. The first torsion member being rotatable relative to the mating portion. The coupler including a second connector having a second torsion member with a second channel, and a coupling portion having a second opening and at least partially disposed within the second torsion member. The second torsion member configured to couple to the first torsion member to couple the first connector to the second connector such that rotation of the second torsion member causes rotation of the first torsion member to cause alignment of the first channel, the first opening, the second channel, and the second opening to form a fluid pathway. The first connector is configured to decouple from the second connector in response to a force exceeding a threshold force.
