First Claim
Patent Images
1. A balloon catheter, the balloon catheter comprisingan expandable balloon carried on the catheter;
- anda radially expandable constraining structure disposed on the balloon,wherein the constraining structure comprises an expanded diameter smaller than an inflated diameter of the balloon, andwherein the constraining structure comprises a plurality of compartments configured to define a plurality of portions of the balloon to expand independently of each other.

Abstract
A constraining structure for use with a balloon catheter includes multiple longitudinal struts and multiple expandable radial rings. The constraining structure can expand radially but may not expand substantially in the longitudinal direction. The constraining structure can have multiple compartments configured to expand independently of one another. Inflating the balloon catheter within the constraining structure can allow for dilation of the blood vessel in a predetermined topography.
