Abstract
A segmented balloon catheter for use in treating a condition of a blood vessel occurring near a bifurcation comprises 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 is mounted on the shaft adjacent the distal end, and a second balloon portion is mounted on the shaft adjacent the first balloon portion. The shaft also comprises 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. In this manner, 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 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.
