Abstract: A novel microwave ablation applicator includes a flexible tubular shaft and a partially encapsulated antenna. The applicator is adapted to be used with an endoscope in order to access remote targets deep within an organ of a patient. Microwave power is emitted from the antenna in a desired radiation pattern by circulating an attenuating liquid through the shaft and across a portion of the antenna. Microwave ablation systems and methods are described.

Abstract: A method and system for estimating calibration parameters of a medical fluoroscope and more particularly a method and system which automatically determines intrinsic and distortion correction parameters of a fluoroscopy device.
Abstract: The present invention is a method to register 3D image data with fluoroscopic images of the chest of a patient. The ribs and spine, which are visible in the fluoroscopic images, are analyzed and a rib signature or cost map is generated. The rib signature or cost map is matched to corresponding structures of the 3D image data of the patient. Registration is evaluated by computing a difference between the fluoroscopic image and a virtual fluoroscopic projected image of the 3D data. Related systems are also described.

Abstract: A system and method are described for determining candidate fiducial marker locations in the vicinity of a lesion. Imaging information and data are input or received by the system and candidate marker locations are calculated and displayed to the physician. Additionally, interactive feedback may be provided to the physician for manually selected or identified sites. The physician may thus receive automatic real time feedback for a candidate fiducial marker location and adjust or accept a constellation of fiducial marker locations. 3D renderings of the airway tree, lesion, and marker constellations may be displayed.

Abstract: Methods, devices, and systems are described herein that allow for improved sampling of tissue from remote sites in the body. A tissue sampling device comprises a handle allowing single hand operation. In one variation the tissue sampling device includes a blood vessel scanning means and tissue coring means to excise a histology sample from a target site free of blood vessels. The sampling device also includes an adjustable stop to control the depth of needle penetration. The sampling device may be used through a working channel of a bronchoscope.

Abstract: A method and system for estimating calibration parameters of a medical fluoroscope and more particularly a method and system which automatically determines intrinsic and distortion correction parameters of a fluoroscopy device.
Abstract: A medical analysis method for estimating a motion vector field of the magnitude and direction of local motion of lung tissue of a subject is described. In one embodiment a first 3D image data set of the lung and a second 3D image data set is obtained. The first and second 3D image data sets correspond to images obtained during inspiration and expiration respectively. A rigid registration is performed to align the 3D image data sets with one another. A deformable registration is perforated to match the 3D image data sets with one another. A motion vector field of the magnitude and direction of local motion of lung tissue is estimated based on the deforming step. The motion vector field may be computed prior to treatment to assist with planning a treatment as well as subsequent to a treatment to gauge efficacy of a treatment. Results may be displayed to highlight.

Abstract: Devices and methods for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease. The methods and devices create channels in lung tissue and maintain the patency of these surgically created channels in tissue. Maintaining the patency of the channels allows air to pass directly out of the lung tissue which facilitates the exchange of oxygen ultimately into the blood and/or decompresses hyper-inflated lungs.

Abstract: Various apparatus and methods for excising tissue are described therein. In certain variations, a method of excising a target tissue mass from a subject, may include advancing an elongate instrument having an opening at its distal end into a subject. A cutting element, e.g., a snare or loop, may be advanced from the distal end of the elongate instrument, wherein the cutting element may be configured to cut tissue. The cutting element may be positioned near the target tissue mass. The cutting element may be actuated, e.g., expanded or deployed, and may perform energy based or mechanical cutting of a section of tissue encapsulating the target tissue mass. The cut section of tissue and the target tissue mass encapsulated therein may be removed from the subject.
