1. A catheter system, comprising:
- (a) an elongate shaft having a proximal end, a distal end, and a separate inflation lumen extending therethrough, the elongate shaft including a longitudinally collapsible section having a longitudinally collapsible guide wire lumen extending therethrough;
(b) an inflatable balloon connected to the distal end of the elongate shaft, and;
(c) a removable guide wire extending through the guide wire lumen.

Abstract
A balloon dilatation catheter is disclosed which incorporates a longitudinally collapsible shaft section including a longitudinally collapsible guide wire lumen. The longitudinally collapsible shaft section may also include a longitudinally collapsible inflation lumen. The longitudinally collapsible shaft section may take the form of a polymer-encased braid, a polymer bellow, or a helical tube. A longitudinally rigid member may be connected to the distal end of the longitudinally collapsible shaft section in order to facilitate extension and contraction of the collapsible section. Methods of using such a catheter system are also disclosed.
