A balloon catheter and method of use for inflating the balloon more effectively, particularly during stent deployment. The balloon catheter includes a catheter shaft and a balloon, wherein the proximal end of the balloon is connected to the distal end of the shaft. A tip is disposed in the interior of the balloon, with the proximal end of the tip extending from the distal end of the catheter shaft and the distal end of the tip connected to the distal end of the balloon. The tip includes a fluid path to facilitate the passage of inflation fluid from the inflation lumen to the interior of the balloon, and the tip may further include a guide wire lumen extending therethrough. The fluid path may be configured to inflate the balloon uniformly or to initially inflate the distal end of the balloon such that a stent loaded on the balloon will not have a tendency migrate distally during deployment. The fluid path may be defined by channel(s) in the tip, groove(s) in the tip, or by utilizing a tip having a non-circular profile.
