    摘要： The present invention is directed to a high density mapping catheter including a number of shape memory electrode fibers and associated methods of construction and operation. The invention ensures good electrical contact between a large number of mapping electrodes and cardiac tissue in relation to a number of cardiac tissue approach angles, including head-on approaches. In addition, the invention allows for a reduced range of deflection angles in relation to deployment and retraction of the electrode fibers, thereby reducing resistance to retraction and reducing stress on the fibers and associated concerns regarding patient safety. The catheter of the present invention allows for rapid acquisition of a large amount of mapping data and allows for a variety of different geometries in relation to sweeping of the catheter across the cardiac tissue.

    摘要： A catheter shaft design facilitates allows for simultaneous stringing of wires and maintains a desired spacing and separation of the wires. In one implementation, a catheter shaft (504) and a core structure (500) are formed in separate manufacturing sequences. The core structure (500) includes a number of receptacles (506) formed in an external surface thereof and may further include a central lumen (508). Wires (501a,b, and 502a,b) are placed into the receptacles (506) and the core structure (500) with wires (501a,b and 502a,b) are inserted into the lumen of the catheter shaft (504). The wires (501a,b, and 502a,b,) can then be connected to electrodes or attached to a catheter tip so as to permit steering of the tip. The design can serve as a platform for various types of catheter.

    摘要： A dual braided catheter shaft includes a flat wire forming the inner braid, thereby potentially allowing for reduced radial thickness of the shaft. In one embodiment, the shaft (100) includes an inner polymer jacket (104), an inner braid (106) formed on the inner jacket (104), an intermediate jacket (108) formed over the inner braid (106), an outer braid (110) formed on the intermediate jacket (108) and an outer jacket (112) formed on the outer braid (110). A preferred construction process involves extruding polymer material directly onto each of the inner and outer braids (106 and 110) so that little or no air gaps remain between the polymer material and the braids (106 and 110). The braiding parameters of the inner and outer braids (106 and 110) can be varied along the length of the catheter to provide varying mechanical properties.

    摘要： A magnetically-guided catheter includes a tip positioning magnet in the distal electrode assembly configured to interact with externally applied magnetic fields for magnetically-guided movement. A magnetically-guided mapping catheter includes an electrically-conductive capsule in the form of a casing that includes a distal ablation surface and isolates the positioning magnet from bio-fluids to prevent corrosion. An open irrigation ablation catheter includes an isolated manifold that isolates the positioning magnet from contact with irrigation fluid to prevent corrosion. A device and method to manufacture a magnetically driven electrode-catheter with flexible tethering includes one or more KEVLAR® fibers, distributed centrally or peripherally within a catheter shaft and oriented longitudinally, transversely, angularly or spirally. A C-shaped extruded catheter introducer (and re-introducer) includes a longitudinally-extending opening for insertion of a magnetically-guided catheter, removal of the introducer from the catheter and which is constructed to facilitate its re-use in a medical procedure.

    摘要： A catheter with a mechanism for omni-directional deflection of a catheter shaft includes a shaft assembly and a controller. The shaft assembly includes a first tubular component that has a preformed curvilinear distal section, a second, substantially straight tubular component with a main axis and an outer shaft. The first and second components are configured for slidable movement therebetween while preserving common rotation so that when the second component is axially moved in a distal direction, the second component deflects the preformed curvilinear section towards the main axis while orientation of the outer shaft is preserved. The controller is configured to effect relative axial movement between the first and second components as well as to effect rotation of the first and second components (and thus also of the preformed curvilinear distal section) without any rotation of the shaft relative to the handle. Varying the deflection of the preformed curvilinear section in combination with variable rotational movement achieves omni-directional distal tip bending.
