Abstract
A very low profile balloon catheter is disclosed that allows for an independently movable, steerable and removable guidewire. After removal of the guidewire, the balloon catheter retains adequately angiographic and hemodynamic characteristics. Such catheter construction allows for exchange of guidewires. A tracking mechanical device is included and provides excellent and easy advancement of the balloon catheter through severe obstructions.
