Publication number: 20150342699Abstract: A chest tube placement apparatus is provided that has an elongate body with a rigid tip that is disposed within the interior of a flexible chest tube and an inflatable member mounted to the body is inflated and the apparatus is then inserted in a prepared location in the chest wall of a patient. The body of the apparatus has at least one axial material transfer channel with a tip port that permits the injection of anesthetic or the aspiration of gases or liquids at the tip. The body also has a light and video camera and display to allow the visualization of the internal structures of the patient during chest tube placement. Once placed and the fluids and gases aspirated, the inflatable member is deflated and the apparatus is removed from the interior of the placed chest tube.Type: ApplicationFiled: June 5, 2015Publication date: December 3, 2015Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventor: Robert Cameron

Publication number: 20150342700Abstract: A method for operating a medical probe includes pressing a distal end of the medical probe, which includes one or more arms that extend diagonally outward from a central shaft and have respective position transducers coupled thereto, against an intra-body surface, so as to cause the arms to exert pressure on the surface and bend with respect to the central shaft in response to the pressure. Positions of the respective position transducers coupled to the arms are measured, and the pressure exerted by the arms is estimated responsively to the measured positions.Type: ApplicationFiled: August 10, 2015Publication date: December 3, 2015Inventors: Assaf Govari, Andres Claudio Altmann, Orit Kolin-Schwartz

Publication number: 20150342702Abstract: Described herein is a dental handpiece for the endodontic treatment of a root canal, including a chuck for attaching and holding an endodontic file, an electric motor having a shaft for driving the endodontic file, and a control unit for controlling the motor, which receives a stream of input data. While monitoring the stream of input data, the control unit determines the current absorbed by the electric motor, and controls the motor so that the file alternates the direction of rotation at a frequency of from 1 to 20 Hz between a first direction and a second direction opposite to the first direction, and whereby the control unit controls the electric motor so that the file continuously rotates in the second direction when the monitored data fulfils a predetermined torque threshold condition during rotation in the first direction.Type: ApplicationFiled: September 5, 2012Publication date: December 3, 2015Inventors: Markus Borgschulte, Lapo Vitali

Publication number: 20150342703Abstract: A dental laser system for treatment of hard and/or soft tissue includes a main chamber housing optical and primary fluid supply subsystems, for directing a laser beam and fluid to a treatment area. A hand piece affixable to the main chamber, includes mating optical and secondary fluid supply subsystems. The hand piece can be rotatable or re-orientable about an optical axis within the hand piece. A lock can maintain a selectable angular orientation of the hand piece relative to the main chamber. A coupling can maintain a fluidic communication between the primary and secondary fluid supply subsystems even when the hand piece is rotated or re-oriented. A sensor and controller can sense a selected angular orientation of the hand piece and adjust the main optical subsystem according to the sensed angular orientation, to align the two optical subsystems. The laser may be controlled using a variable speed foot pedal.Type: ApplicationFiled: June 11, 2015Publication date: December 3, 2015Inventors: Nathan P. Monty, Charles H. Dresser, William H. Groves, JR., Leonid A. Bafitos, Jon R. Quillard
