20100286515 | Novel Methods and Devices for Noninvasive Measurement of Energy Absorbers in Blood - Various embodiments of the present invention include devices for use in determining the concentration of a tissue energy absorber (e.g., hemoglobin) in an individual's blood. In particular embodiments, the device includes a photometric device (e.g., a pulse oximeter) and an imaging device (e.g., an ultrasound imaging device or other suitable imaging device), and the device is adapted for: (A) using the photometric device to measure a change in mass of the tissue energy absorber within a particular volume of the individual's blood between a first point in time and a second point in time, the particular volume of blood being blood within a particular portion of at least one vascular structure, the vascular structure comprising at least one of the individual's vessels (e.g., at least one of the individual's arteries); (B) using an ultrasound imaging device to measure a change in interior volume, between the first point in time and the second point in time, of the particular portion of the vascular structure; and (C) using both the measured change in the mass of the tissue energy absorber, and the measured change in interior volume to determine at least an approximate blood total concentration of the tissue energy absorber within the individual's blood. | 11-11-2010 |
20140343425 | ENHANCED ULTRASOUND IMAGING INTERPRETATION AND NAVIGATION - Systems and techniques are provided in which the orientation of an ultrasonic image display is configured to match the ultrasound probe orientation for ease of interpretation. The position and the orientation of an ultrasound probe are tracked using a tracking device having one or more position and orientation sensors. The orientation of a displayed ultrasound image is automatically adjusted to reflect the position and orientation of the ultrasound probe relative to the body structure being imaged. In some embodiments, a background image (with possible landmarks) is provided based on the location and orientation of the tracked ultrasound probe. | 11-20-2014 |

20080303658 | Hand Washing Compliance Detection System - Systems and methods are provided for monitoring use of hand washing agents to determine compliance with hand hygiene guidelines. A hand washing agent is provided with a detectable, volatile compound, such as odors, which is then rubbed onto a subject's hands using the subject's hand washing technique. After the hand washing event, the subject's hand is then exposed to an detector (such as a badge), which includes a sensor capable of detecting the volatile compound, and an indicator that communicates detection of the volatile compound, indicating use of the hand washing agent and hand hygiene compliance. | 12-11-2008 |
20090131785 | VARIABLE OCCLUSIONAL BALLOON CATHETER ASSEMBLY - Embodiments of the present invention relate to inflatable balloon catheters and methods for deploying an inflatable balloon catheter. For example, one embodiment is directed to a catheter assembly that includes a catheter comprising proximal and distal ends and at least one longitudinal conduit extending between the proximal and distal ends. The catheter assembly also includes an inflatable balloon comprising proximal and distal ends and configured to be at least partially positioned within the longitudinal conduit when the balloon is uninflated. The inflatable balloon is further configured to be inflated when deployed from the conduit such that a diameter of the proximal end of the inflatable balloon remains substantially constant and a diameter of the distal end of the inflatable balloon is variable and capable of at least partially occluding a lumen. | 05-21-2009 |
20100157018 | Display-Based Interactive Simulation with Dynamic Panorama - The subject invention provides a panoramic, interactive, seamless, intuitive, high-resolution and yet extensive simulation tool capable of simulating dynamic events that alter the panoramic view in response to the user's actions or inaction. The dynamic panorama simulation can generate and display novel scenes that are not limited to static “canned” content that has been previously photographed, rendered, recorded, captured or filmed thus providing great flexibility, contextual authenticity and liveliness and, in some instances, unanticipated and surprising but accurate developments in the simulation. | 06-24-2010 |

The tracked instrument can be used to simulate or visualize interactions with internal features of the physical object represented by the physical model. In certain embodiments, one or more of the internal features can be present in the physical model. In another embodiment, some internal features do not have a physical presence within the physical model. | 11-08-2012 |
20130172840 | CONTEXT-SENSITIVE FLOW INTERRUPTER AND DRAINAGE OUTFLOW OPTIMIZATION SYSTEM - Embodiments of the invention provide methods and devices for improved drainage systems and tubing. In one embodiment, a context-sensitive flow interrupter is provided that inhibits or facilitates flow of fluid when engaged with a mating holder. In another embodiment, outflow is optimized through control of the pressure in gas pockets in a tube, drainage tube or assembly. In one such embodiment, gas pockets are vented to inhibit excessive back-pressure or suction on an organ, vessel or cavity being drained. In another such embodiment, loops in the tubes are avoided by using a mechanical template in the form of a groove or peg assembly to thread the slack in the drainage tube to generate a monotonic gradient. In another embodiment, such as for active drainage systems, a bypass channel is provided that allows an applied vacuum to go around an obstruction created by the collection of fluid in an undrained dependent loop. | 07-04-2013 |
