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： The present invention is a catheter actuation handle (14) for deflecting a distal end (18) of a tubular catheter body (12), the handle including an auto-locking mechanism, (54). The handle comprises upper and lower grip portions (24a, 24b), an actuator (20), and an auto-locking mechanism, (54). The auto-locking mechanism (54) is adapted to hold a deflected distal end (18) of the catheter (10) in place without input from the operator. When the distal end (18) of the catheter (10) is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator (20). The auto-locking mechanism (54) acts by providing a second force that resists this force from the distal end (18) and holds the distal end (18) in place. As a result, the operator does not need to maintain contact with the buttons (22a, 22b) to maintain the distal end (18) in a set position.

摘要： A mechanism for omni-directional deflection of a catheter (100) includes a shaft assembly (102) and a controller (104a). Shaft assembly (102) includes first tubular component (118) with a preformed curvilinear distal section, a second straight tubular component (120) with a main axis, and an outer shaft (122). The components (118,120) slide therebetween while preserving common rotation so that when component (120) is axially moved distally, the component (120) deflects the preformed curvilinear section towards the main axis while preserving orientation of outer shaft (122). Controller (104a) effects relative axial movement as well effecting rotation between first and second components (118,120) (and thus also of the preformed curvilinear distal section) without rotating the shaft (122) relative to the handle (112). Varying the deflection of the preformed curvilinear section in combination with variable rotational movement achieves omni-directional distal tip bending.
