1. A method of introducing a collapsed balloon of a balloon catheter into a body passage of a patient through an endoscope, said method comprising:
- (a) loading into the channel of the unattached sheath of an endoscope the distal end of a catheter having a collapsed but inflatable balloon at the distal end and an elongated leg at the proximal end;
(b) loading the elongated leg into and through a working channel in an unattached bridge of an endoscope;

Abstract
A balloon catheter with an unreinforced stem collapses compactly. A method of introducing a balloon catheter into the body passage of a patient consists of loading the balloon end of the catheter into the unattached sheath of an endoscope and passing the elongated tubular leg attached to the balloon through the lumen of a working channel of an unattached bridge of an endoscope; then joining the bridge and the sheath to form a unitary endoscope and introducing the balloon into the body passage of a patient. A kit is disclosed which includes a balloon catheter and a separate adapter which can be used to introduce inflating fluid into the balloon.
