INTEGRATED CROSSING BALLOON CATHETER
First Claim
1. An integrated crossing balloon catheter comprising:
- a catheter shaft having a proximal end, a distal end, a proximal end portion proximate the proximal end, and a distal end portion proximate the distal end;
a hub assembly secured to the proximal end of the catheter shaft;
an inflatable balloon secured to the distal end of the catheter shaft; and
a stiffening tube positioned over the inflatable balloon and the distal end portion of the catheter shaft, the stiffening tube configured to be advanced through a vasculature with the catheter shaft as a unit;
wherein the stiffening tube is translatable along the catheter shaft from a first position in which the inflatable balloon is within the stiffening tube to a second position in which the inflatable balloon is exposed from the stiffening tube.

Abstract
An integrated crossing balloon catheter. The catheter includes a hub assembly secured to the proximal end of the catheter shaft, an inflatable balloon secured to the distal end of the catheter shaft, and a stiffening tube positioned over the inflatable balloon and a distal end portion of the catheter shaft. The stiffening tube is configured to be advanced through a vasculature with the catheter shaft as a unit. The stiffening tube is translatable along the catheter shaft from a first position in which the inflatable balloon is within the stiffening tube to a second position in which the inflatable balloon is exposed from the stiffening tube.

10. An integrated crossing balloon catheter system comprising:
-
a catheter including an elongate shaft extending from a hub assembly at a proximal end of the catheter to an inflatable balloon at a distal end of the catheter, the catheter including an inflation lumen extending through the elongate shaft from the hub assembly to the inflatable balloon for delivering inflation fluid to the inflatable balloon; and a stiffening tube having a proximal end, a distal end and a length measured from the proximal end to the distal end, the stiffening tube surrounding the elongate shaft and in intimate contact with an outer surface of the elongate shaft along a majority of the length of the elongate shaft, the stiffening tube configured to be advanced through a vasculature with the catheter as a unit; wherein the stiffening tube is translatable along the elongate shaft from a first position in which a distal end of the stiffening tube is positioned distal of the inflatable balloon to a second position in which the distal end of the stiffening tube is positioned proximal of the inflatable balloon. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of crossing an occlusion in a vessel lumen, the method comprising:
-
advancing a crossing balloon catheter over a guidewire intravascularly to a location proximal of the occlusion in a vessel lumen, the crossing balloon catheter including an elongate shaft extending between an inflatable balloon and a hub assembly, and a stiffening tube surrounding the balloon and extending proximal of the balloon over a majority of a length of the elongate shaft; positioning the balloon across the occlusion; retracting the stiffening tube from the balloon by translating the stiffening tube proximally relative to the elongate shaft; and inflating the balloon within the occlusion to expand the occlusion by delivering inflation fluid through an inflation lumen of the elongate shaft from the hub assembly to the balloon. - View Dependent Claims (18, 19, 20)
