Abstract
An angioplasty catheter system is disclosed which allows insertion and removal of a guidewire through the inner member of the catheter, yet which inner member includes a portion which is smaller than the cross-section of portions of the guidewire. Advancement and removal of the guidewire are achieved by forming the first portion of the inner member of the catheter shaft from material which is expandable, or which is sufficiently thin to be folded and temporarily secured in place using several techniques.
