摘要： A medical network system is communicatively coupled with a number medical device tracking systems that utilize magnetic systems to track elongate medical devices along anatomical pathways within patients having differing physical attributes, such as height and weight. The medical network system collects tracking records from the medical device tracking systems and applies machine learning and/or artificial intelligence technics to the tracking record data to correlate recorded anatomical pathways with the differing physical attributes. The medical network system receives a patient value set of physical attributes for a specific patient from a medical device tracking system and provides a predicted anatomical pathway based on the correlation and the patient value set. The medical device tracking systems tracts the elongate medical device with respect to the predicted anatomical pathway during placement. The medical device tracking systems may also utilize fiber optic shape sensing systems to track the placement of elongate medical.

摘要： Disclosed are devices, systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various located within the associated chamber of the heart. To create a database of dipole densities, mapping information recorded by multiple electrodes located on one or more catheters and anatomical information is used. In addition, skin electrodes may be implemented. Additionally, one or more ultrasound elements are provided, such as on a clamp assembly or integral to a mapping electrode, to produce real time images of device components and surrounding structures.

摘要： A medical device such as a catheter or endoscope device includes an illumination light source having one or more organic light-emitting diodes (OLEDs). The OLEDs are energized to produce illumination light that is received by an image sensor or camera to produce images of tissue within a patient's body. A heat conductive polymer conducts heat away from the illumination light source.

摘要： Methods and apparatuses provide improved navigation through tubular networks such as lung airways by providing improved estimation of location and orientation information of a medical instrument (e.g., an endoscope) within the tubular network. Various input data such as image data, EM data, and robot data are used by different algorithms to estimate the state of the medical instrument, and the state information is used to locate a specific site within a tubular network and/or to determine navigation information for what positions/orientations the medical instrument should travel through to arrive at the specific site. Probability distributions together with confidence values are generated corresponding to different algorithms are used to determine the medical instrument's estimated state.

摘要： A method and medical system for estimating the deformation of an anatomic structure that comprises generating a first model of at least one anatomical passageway from anatomical data describing a patient anatomy and determining a shape of a device positioned within the branched anatomical passageways. The method and medical system also comprise generating a second model of the plurality of branched anatomical passageways by adjusting the first model relative to the determined shape of the device.
