Abstract: A method of detecting whether a localization element is within or outside of an introducer sheath generally includes obtaining a localization signal from the localization element and detecting the state of the localization element relative to the sheath based upon the quadrature component of the localization signal. A baseline quadrature component is typically established with the localization element outside of the sheath. When the quadrature component deviates from this baseline value, it is indicative of the localization element being within the sheath. Conversely, when the quadrature component remains relatively close to the baseline value, it is indicative of the localization element being outside of the sheath. In an electrophysiology study, the state information can be used to take corrective action with respect to the data being collected.

Abstract: A control system for a medical remote catheter guidance system includes an ECU, a computer-readable memory coupled to the ECU, and user interface (UI) logic stored in the memory configured to be executed by the ECU. The user interface logic receives input from a touch screen display with respect to a view of an anatomical model, associates a user type with the input, and interprets the input according to the associated user type and input. The user interface logic may be further configured to receive simultaneous inputs from at least two different users and to associate different user types with each of said simultaneous inputs. The user interface logic may associate each input with a user type according to a location of the input on the touch screen display.

Abstract: A body (2) for a catheter or sheath is disclosed. The body (2) includes strips (8, 10) formed longitudinally from the proximal (6) portion of the body (2) to the distal (4) portion of the body (2). The strips are formed of different materials. The strips can have different radiopacities, or can be splittable/peelable. The splittable/peelable body comprises a peel mechanism longitudinally extending along its respective length. The peel mechanism can be formed by longitudinally extending regions of interfacial bonding between first and second longitudinally extending strips of polymer material. A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the body (2) along its peel mechanism. The polymer material of the first strip (8) can have a greater amount of radiopaque filler than the polymer material of the second strip (10). Each strip forms at least a portion of an outer circumferential surface of the body (2).

Abstract: A catheter includes a braid assembly having a dual-laminate coating. The braid assembly includes a plurality of braid members interwoven to provide for interstices between the braid members, each braid member having an electrically conductive element, a flexible non-electrically-conductive polymer coating that insulates the electrically conductive element and a thermoplastic bonding adhesive coating. The braid assembly is formed between an inner polymer layer and an outer polymer layer. One or more of the braid members may be coupled to an energy delivery element.
