Abstract: A catheter configured for use with a magnetic field-based localization system includes a distributed location sensor that includes a plurality of individual location sensing coils electrically connected in series. The distributed location sensor has an effective magnetic center based on the individual characteristics of each location sensing coil. The effective magnetic center can be located in a space occupied by another structure such as an irrigation fluid delivery tube. The plurality of individual location sensing coils are generally smaller, thereby easing placement, and collectively, when connected in series, output a relatively strong and noise-free signal.

Abstract: An elongate medical device includes a sensor configured to detect one or more characteristics of an electromagnetic field in which the device is disposed. The sensor includes an electrically-insulative substrate, rectangular in shape, and a patterned, conductive trace disposed on the substrate. The patterned trace includes a plurality of diagonal sections parallel to one another, arranged with a relatively low pitch. The substrate is wrapped into a cylindrical shape thereby forming a three-dimensional spiral capable of functioning as a micro-electromagnetic sensor. A medical positioning system is responsive to the signal from the sensor to determine a position and/or orientation of the sensor.

Abstract: A method for enhancing a three-dimensional (3D) reconstruction of an object comprises obtaining a signal indicative of a static 3D reconstruction of an object disposed in a tracking space, co-registering the 3D reconstruction to the 3D tracking space, collecting enhancement data from a tracked tool disposed in the 3D tracking space, and adding real-time features of the object to the static 3D reconstruction using the enhancement data. A system for enhancing data obtained by a medical system includes an electronic control unit configured to receive a first signal for a static 3D reconstruction of an organ, co-register the static 3D reconstruction to a 3D tracking space for a tracked tool, receive a second signal for enhancement data generated by the tracked tool operating within a region of interest of the organ, and add real-time features of the area of interest to the static 3D reconstruction using the enhancement data.
