Patent number: 9675272Abstract: Methods, systems, and devices are provided for guiding surgical instruments using radio frequency (RF) technology. In general, the methods, systems, and devices can allow a trajectory, e.g., an angular approach, of a surgical instrument relative to a patient to be identified during use of the instrument in a surgical procedure being performed on the patient. The trajectory can be identified using a plurality of RF modules. The methods, systems, and devices can allow the trajectory to be compared to a predetermined trajectory so as to identify whether the trajectory matches the predetermined trajectory. A result of the matching can be communicated to a user of the instrument. Based on the result, the user can maintain the trajectory, e.g., if the trajectory matches the predetermined trajectory, or can adjust the trajectory to closer align the trajectory with the predetermined trajectory, e.g., if the trajectory does not match the predetermined trajectory.Type: GrantFiled: March 13, 2013Date of Patent: June 13, 2017Assignee: DePuy Synthes Products, Inc.Inventors: Sean P. Selover, Joseph Hernandez, John Riley Hawkins, John Dieselman, John Paul Griffin, Jennifer DiPietro

Patent number: 9675273Abstract: The present invention involves a computer-based system and method for detecting and identifying implantable medical devices (“IMDs”) and/or retained foreign objects (“RFSOs”) from diagnostic medical images. In some embodiments, the system provides further identification—information on the particular IMD or RSFO that has been recognized. For example, the system may be configures to provide information feedback regarding the IMD, such as detailed manual information, safety alerts, recall, access to its structural integrity, and/or suggested courses of action in a specific clinical setting/troubleshooting. Embodiments are contemplated in which the system is configured to report possible 3D locations of RSFOs in the surgical field/images.Type: GrantFiled: April 17, 2016Date of Patent: June 13, 2017Assignee: Rush University Medical CenterInventor: Vicko Gluncic

Patent number: 9675274Abstract: A patient monitoring system may receive a photoplethysmograph (PPG) signal including samples of a pulse waveform. The PPG signal may demonstrate morphology changes based on respiration. The system may calculate morphology metrics from the PPG signal, the first derivative of the PPG signal, the second derivative of the PPG signal, or any combination thereof. The morphology metrics may demonstrate amplitude modulation, baseline modulation, and frequency modulation of the PPG signal that is related to respiration. Morphology metric signals generated from the morphology metrics may be used to determine respiration information such as respiration rate.Type: GrantFiled: September 23, 2011Date of Patent: June 13, 2017Assignee: Nellcor Puritan Bennett IrelandInventors: Scott McGonigle, Paul S.
