Apparatus and methods are described for performing angioplasty and stenting with embolic protection. A catheter system includes an angioplasty balloon catheter, a balloon-expandable stent, an embolic protection device and a linking device. The catheter system has an undeployed configuration in which the balloon-expandable stent is mounted on the inflatable angioplasty balloon in an uninflated condition, the embolic protection member is positioned distally to the balloon-expandable stent and the angioplasty balloon, and the linking device is mounted on the catheter shaft of the angioplasty balloon catheter and the device shaft of the embolic protection device. The linking device prevents any relative longitudinal motion of the angioplasty balloon catheter and the embolic protection device, which might lead to accidental dislodgement of the balloon-expandable stent.
