Abstract
Coaxial balloon catheters are described herein. The balloon catheter can include outer and inner tubes in a coaxial relationship, with a balloon attached to an end thereof. A support sleeve can be disposed around the inner tubular member proximate the proximal end of the balloon. The support sleeve can have a channel formed therein to communicate with an inflation lumen and a balloon interior. The channel may be formed by separation of two longitudinal edges extending through the support sleeve. The support sleeve can include an outward extending portion that is sized to engage the distal end of the outer tube in order to limit relative movement between the inner and outer tubes. The support sleeve can be configured to orient the inner tube eccentrically or concentrically relative to the outer tube. The support sleeve can have an elongate body that can be extended in proximal or distal direction.
