What changed

The United States Patent and Trademark Office (USPTO) has issued patent US12582326B2, titled 'Leak detection method for hollow organs,' to QAELON MEDICAL. This patent details a novel method for automatically detecting leaks or inadequate closures in hollow organs after medical procedures. The technique involves injecting a test gas into the organ and measuring its concentration within the body cavity to evaluate the presence and severity of any leak, with controlled pressure differences.

While patent grants are not direct regulations, this innovation may influence future medical device development and surgical practices. Medical device manufacturers and healthcare providers involved in procedures where organ integrity is critical should be aware of this patented technology. Compliance officers in the medical device sector may need to consider this patent for intellectual property due diligence and product development strategies.

Abstract

A method for automatically detecting a clinically relevant leak and/or inadequate closure following a medical procedure, in a hollow organ residing in the interior volume of a body cavity. The test method includes the steps of: injecting, via an adapted injection element, a specific test gas or a gas mixture containing at least one test gas, into the organ, analyzing the gas mixture and measuring the test gas concentration in the interior volume of the body cavity via an adapted detection element and at least during a measurement window, evaluating the likelihood of the presence of a leak and its degree of severity, by comparing stored data and real-time data with each other. The pressure difference between the interior of the hollow organ(s) and the interior volume of the body cavity is controlled or mastered at least at a given moment during at least one measurement window.
