20090149852 | Accurate Cutting About and Into Tissue Volumes with Electrosurgically Deployed Electrodes - Method, system and apparatus for carrying out accurate electrosurgical cutting. A thin resilient electrode is utilized at the forward end region of an instrument that is deployable from a longitudinally disposed slot positioned rearwardly of the tip of the instrument. Lateral sides of the slot extend between a forward location adjacent the tip and a rearward location. The electrode is deployed by urging it forwardly in compression to form an arch profile supported by the abutting slot sides adjacent the forward and rearward locations. Electrosurgically excitable with a cutting output, the electrode may carry out a cutting action both during its deployment and retraction into the noted slot. This permits a pivoting maneuver effective for circumscribing a volume of targeted tissue. | 06-11-2009 |
20100016731 | Hemodynamic Detection of Circulatory Anomalies - The preferred indicator is an injection of indocyanine green dye which is detected and quantified by causing it to fluoresce at a sensor location, for example, at the human ear. Quantification is carried out by using cardiac output procedures and where called for, the Valsalva Maneuver is monitored at a monitor/controller giving visual cues to the patient and operator as to the quality of the necessary exhalation pressure maintenance. | 01-21-2010 |
20110245662 | Hemodynamic Detection of Circulatory Anomalies - The invention generally relates to a system, method and apparatus for detection of circulatory anomalies in the mammalian body. Particularly, apparatus is provided that allows the clinician to quantitatively determine the extent of any anomalies in the pulmonary circulation. Specifically a quantifiable agent is injected into a peripheral location, and the transit of the indicator agent is monitored. Aberrant circulation is them quantified. The preferred indicator is an injection of indocyanine green dye, detected and measured by fluorescence at a sensor location, for example, at the human ear. Quantification is carried out by using cardiac output procedures and alternatively, the use of Valsalva Maneuver is monitored at a monitor/controller providing visual cues to the patient and operator. | 10-06-2011 |
20120330116 | System for Non-Invasive Assay of Liver Function - A system, method and apparatus are disclosed for using a transcutaneous detection system to measure the quantity of a circulating organ activity detection analyte in the blood, and thereby assay the activity of an organ. A preferred organ for assay is the human liver and a preferred indicator is indocyanine green (ICG) dye The procedure is under the control of a monitor/controller having a visual display and capable of providing cues to the operator. A sensor array apparatus for use in conjunction with the system monitor/controller is configured for increased sensitivity of assaying organ function. | 12-27-2012 |
20130225986 | METHOD, APPARATUS AND SYSTEM FOR COMPLETE EXAMINATION OF TISSUE WITH HAND-HELD IMAGING DEVICES - A scan completeness auditing system for screening a volume of tissue comprising a manual image scanning device having an imaging probe, a position tracking system configured to track and record the position of the imaging probe during use, and a controller in communication with the recording system and the manual image scanning device, the controller configured to electronically receive and record the scanned images from the manual image scanning device, and to measure an image-to-image spacing and a scan-to-scan spacing between the scanned images within scan sequence and between scan sequences respectively. The scan completeness auditing system is further adapted to provide an alert to the operator if the image-to-image or scan-to-scan spacing exceeds an acceptable value. | 08-29-2013 |
20140128733 | SYSTEMS AND METHODS FOR HEMODYNAMIC DETECTION OF CIRCULATORY ANOMALIES - Systems and methods for detecting circulatory anomalies such as, for example, right-to-left cardiac and pulmonary shunts. A fluorescing indicator is injected into the bloodstream of a subject. An optical sensor is used to transcutaneously excite the indicator into fluorescence and to transcutaneously detect the fluorescence, and a relative concentration of the indicator is determined as a function of time. An indicator dilution curve is generated from the relative concentration readings, the curve shape is analyzed for the indication of a shunt and, if a shunt is detected, a ratiometric area under the curve analysis is performed and combined with a calculated cardiac output value to provide a shunt conductance value. A Valsalva maneuver may be performed as a part of the method. System embodiments may include a controller/monitor that monitors, times, cues and/or analyzes various steps of a shunt detection test. | 05-08-2014 |
20140276034 | Apparatus Detection of Circulatory Anomalies - A system, and apparatus for detecting and quantifying circulatory anomalies, including right-to-left cardiac shunts. The apparatus implements a sensor system useful in connection with a circulatory indicator delivery system. The sensor apparatus is preferably configured with a series of emitter/detector pairs to optimize the sensitivity of detection of the circulating indicator. Sensing of the indicator concentration takes place at an arterial vasculature, for example, the pinna of the human ear. A monitor/controller calculates and displays a indicator/dye dilution curve to assess for the presence of a cardiac shunt. The monitor/controller further corrects the indicator/dilution curve displayed for any recirculation phenomena and can quantify any right-to-left shunt calculated conductance associated with detected shunts. | 09-18-2014 |
20150213725 | METHOD, APPARATUS, AND SYSTEM FOR VIEWING MULTIPLE-SLICE MEDICAL IMAGES - Systems and methods are disclosed for reviewing multiple images while monitoring a reviewer's attentiveness during the review. Systems include an image review system configured to output a series of images to the display and a user attention monitoring system configured to monitor at least one attention parameter for a user during the user's review and to generate user attention data based on the at least one attention parameter monitored, wherein the image review system is configured to output the second image to the display if the user attention data indicates sufficient user attentiveness. The image review system may also be configured to generate distraction or review breaks during the review period. | 07-30-2015 |
