Publication number: 20200297967Abstract: 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.Type: ApplicationFiled: June 2, 2020Publication date: September 24, 2020Inventors: Samsun Lampotang, Nikolaus Gravenstein, Wilhelm K. Schwab, David E. Lizdas, Francesca K. Enneking

Publication number: 20200221955Abstract: According to a method for using near infrared spectroscopy to detect compartment syndrome, an optics array is placed around a body region of a patient that contains a vulnerable compartment of tissue. The optics array includes emitters that generate photons at NIR wavelengths and detectors that detect photons at NIR wavelengths. Photons are emitted from at least one of the emitters, and detected at more than one of the detectors after those photons traveled through the tissues of the body region of the patient. A cross-sectional measure of regional differences in absorption within a cross-section of the body region of the patient is displayed so as to allow detection of compartment syndrome. The method is carried out with a device for using near infrared spectroscopy to detect compartment syndrome.Type: ApplicationFiled: September 10, 2018Publication date: July 16, 2020Inventors: Patrick J.

Publication number: 20180140381Abstract: A computer-implemented method and system for guiding the placement of orthodontic brackets are provided. The system can include an at least one indexing tool designed to conform to at least a portion of a patient's teeth or alveolar process. The system can receive signals from a sensor at the indexing tool as well as signals from a sensor at a bracket positioning tool in order to track spatial location—and/or orientation of one or more brackets relative to the surface of the patient's actual or modeled teeth. A method for guiding the placement of orthodontic brackets involves detecting the location and/or orientation of a bracket with respect to at least one tooth of a patient and notifying the orthodontist that the actual bracket position and/or orientation meets specified criteria with respect to planned placement coordinates for the bracket. The method can further include collecting the planned placement coordinates for each bracket tooth combo during a planning phase.Type: ApplicationFiled: June 27, 2016Publication date: May 24, 2018Inventors: NIKOLAUS GRAVENSTEIN, CALOGERO DOLCE, SAMSUN LAMPOTANG, DAVID ERIK LIZDAS
