Abstract
A variable length balloon catheter is provided. The balloon catheter includes a catheter shaft having a distal portion, a balloon and an adjustment device. The balloon is in fluid communication with a distal end of the catheter shaft. The adjustment device includes an outer sleeve and an attachment structure. The outer sleeve is configured to be generally co-axially received over the distal portion of the catheter shaft and includes a distal end configured to restrict inflation proximal the distal end. Further, the outer sleeve is configured such that at least a portion of the outer sleeve is slidable relative to the distal portion of the catheter shaft such that a distal end of the outer sleeve relative to the balloon can be varied. The attachment structure is similarly disposed at the distal portion of the catheter shaft and is configured to selectively secure at least a portion of the outer sleeve to the distal portion of the catheter shaft such that the outer sleeve will not move upon inflation of the balloon.
