Patent number: 8583214Abstract: To visually support a catheter ablation in the heart, three-dimensional image data have been used prior to the intervention. During ablation, the position of the catheter is pinpointed by an orientation system. The orientation system acquires electroanatomical 3D mapping data. The two-dimensional image data is assigned to the 3D mapping data in the correct position and dimensions which is a time-consuming step. The invention makes provision for the orientation system being in a fixed location relative to the X-ray system so that a positionally and dimensionally correct alignment of the X-ray image data set with the 3D mapping data is no longer required. An image or surface based 3D-3D alignment of the three-dimensional data acquired prior to the intervention with the three-dimensional X-ray image data is considerably less time-consuming than alignment thereof with the 3D mapping data and is more reliable because more structures is recognized in the three-dimensional X-ray image data.Type: GrantFiled: September 21, 2006Date of Patent: November 12, 2013Assignee: Siemens AktiengesellschaftInventors: Jan Boese, Norbert Rahn

Publication number: 20130296696Abstract: The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment.Type: ApplicationFiled: July 9, 2013Publication date: November 7, 2013Inventors: Nikolai Aljuri, Rodney C.

Patent number: 8571638Abstract: A miniature surgical robot is attached directly to the bone of a patient at a surgical site, thereby locating the robot precisely on the bone. Intraoperative two-dimensional images of the robot on the bone together with an image referencing element disposed in a predetermined position relative to the robot, are correlated to form a three dimensional image.

Patent number: 8548562Abstract: An imaging and diagnostic system and method to differentiate between malignant and non-malignant tissue of a prostate and surrounding region. The system acquires imaging data from the prostate and surrounding proximal region, and processes the data to differentiate areas of tissue malignancy from non-malignant tissue. A sectioning device or ablative device is provided. The ablative device is operable by automation for receiving the imaging output coordinates and defining the trajectory and quantity of energy or power to be delivered into the malignant tissue. A control system determines calculated energy or power to be deposited into the malignant tissue during ablation, to minimize destruction of the non-malignant tissue within the prostate and surrounding tissue. The system operates on generated ablative device output data.Type: GrantFiled: March 16, 2007Date of Patent: October 1, 2013Inventors: John Trachtenberg, Masoom A. Haider, Brian Campbell Wilson

Patent number: 8548567Abstract: The present invention relates to a system for performing and monitoring minimally invasive interventions with an x-ray unit, in which at least one x-ray source and one x-ray detector can traverse a circular track through an angle range, an ECG recording unit, an imaging catheter, a mapping unit with a mapping catheter and an ablation unit with an ablation catheter. The system comprises a control and evaluation unit with interfaces for the units and catheters, which enable an exchange of data with the control and evaluation unit. The control and evaluation unit is designed for processing measurement or image data which it receives from the catheters and units, and for controlling the catheters and units for the capture of the measurement or image data. The workflow from the examination through to the therapy, particularly with regard to the treatment of tachycardial arrhythmias, is covered completely and continuously by the proposed system.Type: GrantFiled: July 13, 2006Date of Patent: October 1, 2013Assignee: Siemens AktiengesellschaftInventors: Michael Maschke, Reinmar Killmann

Publication number: 20130237814Abstract: One or more techniques and/or systems described herein provide for generating a radiographic image and ultrasound image depicting parallel planes of an object under examination and may be used in conjunction with radiographic or ultrasound techniques known to those in the field (e.g., x-ray tomosynthesis, computed tomography ultrasound imaging, etc.). An ultrasound frontend component is configured to transmit ultrasound waves in a direction substantially parallel to a trajectory of radiation. In one example, one or more radiographic images of an object are spatially coincident to one or more ultrasound images of the object in the same position and/or geometric shape/volume, and the images may be combined to generate a combined image depicting features of the ultrasound image (e.g., the sensitivity of the ultrasound image) and features of the radiographic image (e.g., the morphological details of the radiographic image).Type: ApplicationFiled: November 16, 2010Publication date: September 12, 2013Inventor: Sorin Marcovici

Patent number: 8532746Abstract: An automatic atherectomy system uses a rotary burr at the tip of a catheter as a sensing device, in order to measure both electrical conductivity and permittivity of surrounding tissue at multiple frequencies. From these parameters it is determined which tissue lies in different directions around the tip. A servo system steers the catheter tip in the direction of the tissue to be removed. In non-atherectomy applications the rotary burr can be replaced with any desired tool and the system can be used to automatically steer the catheter to the desired position. The steering may be done hydraulically, by pressurizing miniature bellows located near the catheter tip.Type: GrantFiled: February 24, 2012Date of Patent: September 10, 2013Assignee: Kardium Inc.Inventors: Daniel Gelbart, Samuel Victor Lichtenstein

Patent number: 8532738Abstract: A method, including constructing a simulated surface of a body cavity, and pressing a distal end of a probe against a wall of the body cavity. While pressing the distal end against the wall, position measurements are accepted from the probe indicating a position of the probe within the body cavity, and force measurements are accepted from the probe indicating a force between the distal end and the wall. A distortion in the simulated surface is created at the position indicated by the position measurements, so as to form a distorted surface, upon detecting that the force measurements exceed a predefined amount. The distorted surface is then displayed.Type: GrantFiled: November 4, 2010Date of Patent: September 10, 2013Assignee: Biosense Webster (Israel), Ltd.Inventor: Eliahu Zino
