Devices and Methods for Assessing Pulmonary Status Using Optical Oxygenation Sensing
Summary
USPTO granted patent US12599321B2 to Cardiac Pacemakers, Inc. covering devices and methods for assessing pulmonary status using optical oxygenation sensing. The patent claims an oxygenation monitoring device with an optical emitter configured to emit light at wavelengths from 100 nm to 2000 nm and a detector to measure incident light propagating through lung tissue to determine oxygenation status. The patent application (No. 17864907) was filed on July 14, 2022, and contains 17 claims.
What changed
USPTO issued patent US12599321B2 to Cardiac Pacemakers, Inc. for devices and methods of assessing pulmonary status via optical oxygenation sensing. The patent covers oxygenation monitoring devices with optical emitters operating in the 100-2000 nm wavelength range and optical detectors to measure light propagation through lung tissue for determining oxygenation status.
For medical device manufacturers and healthcare providers, this patent establishes intellectual property protection around pulmonary assessment technology using optical sensing methods. Companies developing similar optical oxygenation monitoring devices for pulmonary assessment should consider potential licensing needs or design-around strategies to avoid infringement of the granted claims.

Abstract
Embodiments herein relate to devices and methods for assessing pulmonary status using optical oxygenation sensing. In an embodiment, an oxygenation monitoring device can be included having a first optical emitter, wherein the first optical emitter can be configured to emit light at a first wavelength from 100 nanometers (nm) to 2000 nm. The oxygenation monitoring device and further include a first optical detector, wherein the first optical detector can be configured to detect incident light. The device can be configured so that emitted light from the first optical emitter propagates through a lung tissue and detected incident light can be used to determine an oxygenation status of the lung tissue. Other embodiments are also included herein.
