Claim:
1. A balloon delivery catheter apparatus comprising: a catheter tubing defining a lumen therethrough and having proximal and distal ends; a balloon disposed near a distal end of the catheter tubing and moving between deflated and inflated states; a core wire having a proximal end attached to the catheter tubing inside the lumen and extending distally away and substantially co-axially with the catheter tubing through the balloon to a distal free end; proximal and distal balloon control bands concentrically arranged around respective proximal and distal end portions of the balloon, each balloon control band comprising an elastic material that expands during inflation of the balloon and contracts upon deflation of the balloon, the balloon control bands impeding expansion of the proximal and distal end portions of the balloon and assisting deflation of the balloon after balloon inflation, wherein the balloon control bands each have a diametric cross-section larger than the balloon in its uninflated state and an unexpanded stent received over the balloon to impede axial movement of the unexpanded stent off of the balloon; a coil disposed around the core wire, the coil having a proximal end attached to at least one of the distal end portion of the balloon and the distal balloon control band; and a handle received by the proximal end of the catheter tubing, the handle comprising:
