摘要: A machine and method for forming a spring coil in a length of hollow, cylindrical thermoplastic tubing comprises clamping the ends of a predetermined length of cylindrical thermoplastic tubing between first and second opposing spaced clamping members. In the machine, these clamping members include aligned first and second sections of a mandrel. These first and second clamping members then are rotated relative to one another by a predetermined amount selected to be slightly in excess of 360°, while the mandrels are simultaneously moved toward one another, to shorten the distance between the ends of the length of tubing, while the coil is formed. At the end of this relative rotation, the mandrel sections engage one another. The clamped tube, with the coil now formed around the mandrels, is rotated and simultaneously heated to the thermosetting temperature of the tubing. After a sufficient time to establish thermosetting of the coil, the heat is removed. Rotation continues while the tube is cooled. Following the cooling cycle, the apparatus operates to release the tubing with the formed coil in it from the machine.

摘要: A hollow lumen cable is formed by helically winding inner and outer coils with the helices of each coil being in abutting relationship and the outer coil inner diameter being less than the outer coil inner diameter being less than the outer, peripheral, diameter of the inner coil. Preferably, each coil is multifilar. After the coils are wound, an unwinding force is applied to the outer coil and the inner coil is inserted into the outer coil to have its winding inclined opposite to that of the outer coil; and thence, the outer coil is allowed to contract to form an interference fit with the inner coil. The cable may be incorporated as part of various medical systems e.g., implantable pumps or other rotatable medical apparatuses. The cable is bendable about the tight radii, has a high torque transfer, a small outer diameter, and a hollow lumen through which fluid, wires or medial devices may pass.

摘要: A guide wire handle for selectively stiffening a guide wire and releasably locking the guide wire in a stiffened condition that includes a main body that can be held by one hand and has a rectangular opening in which there is mounted a slide member that is movable between a guide wire datum position and a guide wire stiffened position. The main body and slide member have elongated linear slits and bores with or without metal plate extended therein. A sleeve on the core wire proximal end abuts against the slide member plate and the proximal end of the coil spring abuts against the main body plate such that as the slide member a plate is moved away from the body plate, the coil spring is compressed and the core wire is placed in tension to stiffen the guide wire. The slide member and main body include cooperating locking parts for releasably retaining the slide member in the guide wire stiffen condition and is operable by the same hand holding the handle to an unlocked condition whereby the guide wire moves the slide member relative to the main body to the guide wire nearly fully relaxed condition. The slide member also includes a spring part to resiliently retain the slide member in a datum position while permitting movement against the resilient action to facilitate loading the handle with the guide wire.
