SURGICAL INSTRUMENTS WITH SENSORS FOR DETECTING TISSUE PROPERTIES, AND SYSTEM USING SUCH INSTRUMENTS
Publication number: 20230363658Abstract: A system is provided that furnishes expert procedural guidance based upon patient-specific data gained from surgical instruments incorporating sensors on the instrument's working surface, one or more reference sensors placed about the patient, sensors implanted before, during or after the procedure, the patient's personal medical history, and patient status monitoring equipment. Embodiments include a system having a surgical instrument with a sensor for generating a signal indicative of a property of a subject tissue of the patient, which signal is converted into a current dataset and stored. A processor compares the current dataset with other previously stored datasets, and uses the comparison to assess a physical condition of the subject tissue and/or to guide a procedure being performed on the tissue.Type: ApplicationFiled: December 6, 2022Publication date: November 16, 2023Inventors: Jason Matthew ZAND, Gregory Scott FISCHER -

Publication number: 20220287603Abstract: Apparatus, systems, and methods are provided that generate in vivo maps of oxygenation measurements of biological tissue. These may include surgical instruments and stand-alone imaging systems with incorporated oxygen sensing capability. Oxygenation maps can be determined via fluorescent or phosphorescent lifetime imaging of an injectable probe with an oxygen-dependent optical response. Probe configuration and methods and apparatus of injecting the probe into the tissue are provided. Methods and apparatus for temperature compensation of temperature-dependent lifetime measurements are provided to improve oxygenation measurement accuracy. Oxygen maps may be registered with visible light images to assist in assessing tissue viability or localize anomalies in the tissue.Type: ApplicationFiled: October 21, 2021Publication date: September 15, 2022Applicant: SURGISENSE CORPORATIONInventors: Jason Matthew Zand, Gregory Scott Fischer, Justin Thomas Knowles

Publication number: 20100081895Abstract: A system is provided that furnishes physiological or biomechanical parameters from sensors placed upon or within a subject. The system comprises radio frequency energized biosensor (RFEB) devices that are powered by and communicate with an external receiver and monitoring apparatus. One embodiment of the system provides for infant monitoring in a crib utilizing RFEB devices incorporated into a dermal patch. Said patch communicates with a receiver suspended above the crib and alerts of early warning signs of sudden infant death syndrome (SIDS) or other physiologic abnormalities. Another embodiment comprises implantable RFEB devices that relay information related to the condition of an internal tissue, organ, or cavity to an external receiver, monitor, and recorder. Other embodiments include wearable sensors for detecting a subject attempting to get out of bed, dislodge medical equipment, or stray from a given location.Type: ApplicationFiled: June 21, 2007Publication date: April 1, 2010Inventor: Jason Matthew Zand
