    摘要： A guidable, or steerable, or deflectable catheter is provided that includes a proximal portion and a distal portion for insertion into a body cavity. A selectively deflectable segment having an anisotropic bending stiffness for deflection in individual planes is incorporated into the distal portion of the catheter shaft. Upon actuation of pull wires, the distal deflectable segment may be deflected to move/sweep the distal catheter tip through a sweeping plane. The anisotropic bending stiffness of the distal deflectable segment permits in-plane movement of the distal catheter tip in the sweeping plane while resisting any out-of-plane movements. In one arrangement, stiffening elements are selectively disposed within the distal deflectable segment such that the out-of-plane bending stiffness is largely increased and greater than the in-plane bending stiffness for deflection in the sweeping plane. In another arrangement, the cross section of a distal deflectable segment is altered to produce anisotropic area inertias of moment about its centroidal axes, and thus anisotropic bending stiffnesses.

    摘要： A method of manufacturing a catheter assembly generally includes providing a catheter shaft having an outer layer and an inner reinforcing layer; removing at least a portion of the outer layer from a length of the distal end of the catheter shaft in order to expose a distal segment thereof; providing an inner jacket segment; axially engaging the inner jacket segment with an interior surface of the distal segment of the catheter shaft; providing an outer jacket segment around at least the exposed exterior region of the distal segment of the catheter shaft; and bonding the distal segment of the catheter shaft to the inner jacket segment and the outer jacket segment.

    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： Catheter systems and methods are disclosed. An exemplary catheter includes an outer tubing housing and an inner fluid delivery tubing, the inner fluid delivery tubing having at least one fluid delivery port. The catheter also includes a deployment member movable axially within the inner fluid delivery tubing. A plurality of splines are each connected at a proximal end to the outer tubing and at a distal end to deployment member. A seal is provided between the outer tubing and the inner fluid delivery tubing. A gasket is provided between the deployment member and the inner fluid delivery tubing. Both the seal and the gasket are configured to prevent blood or other fluid from ingressing into the outer tubing.
