Abstract:
A segmented balloon catheter for use in treating a condition of a vessel occurring near a bifurcation that is defined by the intersection of a main vessel with a side branch vessel, the segmented balloon catheter comprising:a shaft which includes a proximal end, a distal end and a longitudinal passageway that extends therethrough from the proximal end to the distal end; a first balloon portion which is mounted on the shaft adjacent the distal end; a second balloon portion which is mounted on the shaft adjacent the first balloon portion; the shaft comprising a transverse port which extends between the longitudinal passageway and the exterior of the segmented balloon catheter from between the first and second balloon portions; wherein a proximal end of a first guide wire which is pre-positioned in the main vessel may be inserted into the distal end of the shaft and threaded through the longitudinal passageway and out the proximal end of the shaft; and wherein a proximal end of a second guide wire which is pre-positioned in the side branch vessel may be inserted into the transverse port and threaded through the longitudinal passageway and out the proximal end of the shaft; whereby the first and second balloon portions may be guided to the bifurcation on the first and second guide wires.
