Abstract: A regrooming device for a balloon catheter, comprising a tubular member having a proximal section, a distal section, and an inner lumen extending therein configured to receive a balloon of a balloon catheter; and a mandrel disposed within the inner lumen and having a proximal end configured to enter a guide wire lumen at a distal section of the balloon catheter to facilitate guiding the distal section of the catheter into the inner lumen of the regrooming device, and a distal end secured to the distal section of the tubular member.

Abstract: Angled balloon dilatation catheter having a flexible elongate tubular member with first and second lumens extending therethrough and with proximal and distal extremities. An angled balloon is carried by the distal extremity of the tubular member. The elongate tubular member has a tubular element extending through the balloon. The first lumen extends through the tubular element and is capable of receiving a guide wire so that the guide wire extends therethrough. The second lumen is in communication with the interior of the angled balloon for inflating and deflating the balloon. The balloon subtends a predetermined interior angle.
