Abstract
A dilation catheter for use in medical procedures is provided including a dilation balloon disposed on the distal end of a flexible tubular shaft. The balloon has perfusion characteristics and may be varied between a collapsed condition and an expanded condition by the introduction of fluid into the balloon. The balloon includes a compliant portion which extends radially outwardly when the balloon is in its expanded condition for engaging a body vessel wall and a non-compliant longitudinal section which traverses the length of the balloon and does not extend radially outwardly when the balloon is in its expanded condition, forming a perfusion channel.
