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