The catheter electrode model is tracked, by a central processing unit, and is detected by the graphics processing unit, in subsequent frames of the fluoroscopic image sequence by detecting catheter landmark candidates in the subsequent frames of the fluoroscopic image sequence using at least one trained catheter landmark detector, and outputting the catheter model tracking and landmark detection results of for each frame of the fluoroscopic image sequence.Type: GrantFiled: September 19, 2012Date of Patent: December 29, 2015Assignee: Siemens AktiengesellschaftInventors: Wen Wu, Terrence Chen, Norbert Strobel, Dorin Comaniciu

Patent number: 9218668Abstract: An apparatus for detecting different subjects on the basis of vital signs includes an image detection unit for detecting radiation from a field of view and for providing image data from the field of view. A detection unit defines image sections in the image data and detects movement patterns in each of the different image sections. An identification unit identifies vital signs in the different image section on the basis of the movement pattern. An analysis unit analyzes the image data and detects the different subjects in the field of view on the basis of a spatial separation of the image sections or of groups of image sections in which the vital signs are identified.Type: GrantFiled: February 24, 2014Date of Patent: December 22, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Mukul Julius Rocque

Patent number: 9211091Abstract: A system and method for identifying the location of a medical device within a patient's body may be used to localize the fossa ovalis for trans-septal procedures. The systems and methods measure light reflected by tissues encountered by an optical array. An optical array detects characteristic wavelengths of tissues that are different distances from the optical array. The reflectance of different wavelengths of light at different distances from an optical array may be used to identify the types of tissue encountered, including oxygenated blood in the left atrium as detected from the right atrium through the fossa ovalis.Type: GrantFiled: November 25, 2014Date of Patent: December 15, 2015Assignee: Medtronic Ablation Frontiers LLCInventors: Can Cinbis, Xiaonan Shen, Jonathan Kuhn

Patent number: 9215366Abstract: An endoscope system includes an imaging section that captures an object via an optical system and an image sensor, an observation state determination section that determines the observation state of the object captured by the imaging section, and an aperture control section that controls the state of an aperture included in the optical system based on the observation state, the aperture control section controlling the state of the aperture so that the resolution determined by the diffraction limit due to the aperture is equal to or higher than a resolution determined by the image sensor when the observation state determination section has determined that the observation state is a first observation state, and stopping down the aperture as compared with the state of the aperture in the first observation state when the observation state determination section has determined that the observation state is a second observation state.Type: GrantFiled: January 25, 2013Date of Patent: December 15, 2015Assignee: OLYMPUS CORPORATIONInventor: Yasunori Morita

Patent number: 9204820Abstract: A catheter is responsive to external and internal magnetic field generators for generating position data of the catheter position and pressure data to determine pressured exerted on a distal end of the catheter when engaged with tissue, with a reduced number of sensing coils and reduced number of sensing coil leads for minimizing lead breakage and failure. The catheter includes a distal section adapted for engagement with patient tissue, where the distal section has a proximal portion, a distal portion and a flexible joint with a resilient member adapted to allow axial displacement and angular deflection between the proximal and distal portions of the distal section. The catheter may have three or less sensing coils with three or less leads, each transmitting signals between a respective sensing coil and the signal processor.Type: GrantFiled: December 31, 2012Date of Patent: December 8, 2015Assignee: Biosense Webster (Israel) Ltd.Inventors: Jeffrey L. Clark, Meir Bar-Tal, George Kamin, Avram Dan Montag, Mark Stanley

Patent number: 9208559Abstract: In a method and an apparatus for implementing a gastric artery chemical embolization (GACE) catheterization procedure, an x-ray imaging system obtains a first current image data set of the patient prior to implementing the GACE procedure, and a second current image data set that shows the blood vessels that supply the fundus of the subject. The first and second current image data sets are fused to form a first fusion image data set. A second fusion image data set is then formed by fusion of the first fusion image data set with a catheter-position-indicating data set, obtained during the GACE procedure. The second fusion image data set is displayed during the GACE procedure or control data for a lightweight robot, used to operate and guide the catheter, can be derived from the second fusion image data set.Type: GrantFiled: July 25, 2014Date of Patent: December 8, 2015Assignee: Siemens AktiengesellschaftInventor: Michael Maschke

Patent number: 9204935Abstract: A method of generating a diagnosis map of at least a portion of the heart includes inserting an electrode within the portion of a heart, robotically moving the electrode therein, measuring electrophysiology information at a point on the surface of the heart, associating the measured electrophysiology information with position information for the point on the surface of the heart, repeating the measuring and associating steps for a plurality of points on the surface of the heart, thereby generating a plurality of surface diagnostic data points, and generating the diagnosis map therefrom. The electrode may be moved within the heart randomly, pseudo-randomly, or according to one or more predetermined patterns. A three-dimensional model of the portion of the heart may be provided and presented as a graphical representation, either with or without information indicative of the measured electrophysiology information superimposed thereon.Type: GrantFiled: June 17, 2014Date of Patent: December 8, 2015Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: John A. Hauck, Jeffrey A. Schweitzer, Kedar Ravindra Belhe

Patent number: 9204841Abstract: A catheter is responsive to external and internal magnetic field generators for generating signals representing position and pressure data, with a reduced number of sensing coil leads for minimizing lead breakage and failure. The catheter includes a flexible joint with pressure sensing and position coils, at least pair of a pressure sensing coil and a position coil are serially connected. Methods of calibrating a catheter for position and pressure sensing, and detecting magnetic field interference with one catheter by another catheter or other metal or ferrous object advantageously use signals between two sets of sensors as a “back up” or “error check”.Type: GrantFiled: December 31, 2012Date of Patent: December 8, 2015Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Jeffrey L.
