    Abstract: A device comprising a flexible elongate member having proximal (72) and distal extremities (41). A flexible coil spring is provided having proximal and distal extremities. The proximal extremity of the coil spring is secured to the distal extremity of the flexible elongate member. A shape memory alloy element (46) is disposed within and extends substantially longitudinally of the coil spring (36). The shape memory alloy element has a memory which makes it attempt to assume a straight shape when an electrical current is passed through and heats the same. The shape memory alloy element (46) also has a stiffness which increases with the temperature of the element. An electrical current supply (67) is provided for supplying an electrical current to the shape memory alloy element for changing the stiffness of the shape memory alloy element to thereby stiffen the distal extremity of the flexible elongate member.

    Abstract: A low profile balloon-on-a-wire catheter (11) comprising a flexible elongate tubular member (12) having proximal and distal extremities (13, 14). A balloon inflation/deflation lumen extends from the proximal extremity to the distal extremity. An inflatable balloon (26) is carried by the distal extremity of the flexible elongate tubular member (12). The flexible elongate tubular member (12) carries means which establishes communication between the lumen and the interior of the inflatable balloon (31). A removable inflation device (51) is removably secured to the proximal extremity of the flexible elongate tubular member (12) for supplying an inflation fluid to the lumen for inflating and deflating the balloon (26). The removable inflation device (51) forms a high pressure seal with the proximal extremity of the flexible elongate tubular member (12). The removable inflation device (51) is free of obstructions so that another balloon catheter can be advanced over the proximal extremity of the flexible elongate tubular member (12) which serves as stand-alone guide wire. The distal extremity of the catheter is formed so that it is mechanically shapable or can be electrically deflectable to facilitate steering of the distal extremity.
