The multi-purpose balloon catheter comprises a tubular body having a proximal end portion, a distal end portion and at least two lumens within the tubular body. The distal end portion has three spaced apart balloons thereon, the distal balloon being an occlusive balloon, the middle balloon being a stent mounting balloon and the proximal balloon being an occlusive balloon.

Multi-purpose balloon catheter

The stent delivery method and apparatus uses an elongate sheath having a rounded or tapered distal end portion which has a central opening and which is constructed in a manner that permits the distal end portion to expand easily. The method comprises the steps of: placing a stent on a balloon catheter or a balloon on a balloon guidewire thereby forming a stent on a balloon assembly; placing the stent on a balloon assembly in the elongate sheath having an elongate axis; pushing the sheath and stent on a balloon assembly to a desired site in the lumen of a vessel; positioning the stent on a balloon assembly at the desired site; withdrawing the sheath from the stent on a balloon assembly causing the distal end portion of the sheath to expand to pass over the stent and leaving the stent and balloon at the desired site in the lumen; expanding the balloon and stent to expand the stent to a desired diameter; collapsing the balloon; and, removing the balloon and the sheath from the lumen. The central opening permits a guidewire tip to extend therethrough.
