Nanto’s technique for changing a PTCA balloon catheter over a regular-length guide wire

Nanto’s technique for changing a percutaneous transluminal coronary angioplasty (PTCA) balloon catheter over a regular-length guide wire is demonstrated in this vidoe on youtube: http://www.youtube.com/watch?v=mjEjbSNL4IY (unfortunately the description audio is not in English). This technique is used for changing an over the wire balloon catheter with a regular length of guide wire. But in the 1994 description by Nanto an colleagues available on Pubmed [Nanto S, Ohara T, Shimonagata T, Hori M, Kubori S. A technique for changing a PTCA balloon catheter over a regular-length guidewire. Cathet Cardiovasc Diagn. 1994;32:274-7], they connected the inflation device to the central guide wire lumen of the balloon catheter after pulling back the catheter until the proximal end of the guide wire was just inside. The balloon catheter was further pulled back while applying pressure with the inflation device, leaving the guide wire in the coronary artery. Nanto and colleagues could use this technique successfully in 149 of the 163 procedures attempted. In the youtube video (link above), they seem to have simplified it further by using just a filled luer lock syringe instead of the inflation device.
