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： 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.

摘要： A contact sensing assembly including a catheter and an electrode including a tip portion and a base portion, and a generally central axis, with the electrode being connected to a distal end of the catheter. Optical sensor(s) may be provided for emitting and/or receiving an optical signal, with a part of the optical signal being transverse to the central axis. Optical interference member(s) may be provided for interfering with the optical signal. A method for sensing contact force exerted by an electrode on a tissue includes directing an optical signal along a portion of a catheter, emitting and/or receiving an optical signal, with a part of the optical signal being at a predetermined angle relative to the central axis, and sensing changes in intensity of the optical signal based on displacement associated with the electrode tip portion based on the contact force exerted by the electrode on the tissue.
