    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 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 deflectable medical device incorporates a strut that is configured to reduce or eliminate axial shortening of the deflectable portion of the medical device, for example, the deflectable distal end portion of a catheter or access sheath. The strut may is coaxially disposed in the medical device in the section that is contemplated to undergo the repeated deflection. The strut provides improved column strength and axial restoration. The strut may be stent-like device, an elongate device having opposing ends coupled by a connecting lattice involving a plurality of helical connecting elements or a tube having a plurality of circumferentially-extending slots arranged in longitudinally-extending rows.
