1. A balloon-on-a-wire device comprising: an elongated wire having a length, an outer surface with at least one cut therein, polymer film covering at least a portion of the outer surface, a proximal end, and a distal end; an expandable balloon at the distal end of the wire; a sleeve consisting of a strip of material attached to a portion of an outer surface of the balloon, forming a guidewire channel along at least a portion of the expandable balloon; wherein the sleeve is disruptable to cause a guidewire placed between the strip of material and the outer surface of the balloon to release from the expandable balloon when the sleeve is disrupted and wherein the expandable balloon has a compacted dimension and an expanded dimension; a guidewire is located within the guidewire channel; the strip of material includes a separation line; and the strip of material is disrupted by parting along the separation line when the expandable balloon is expanded, separating the guidewire from the balloon.
