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.
Claims15
A balloon catheter, the balloon catheter comprising
- an expandable balloon carried on the catheter;
- and
- a radially expandable constraining structure disposed on the balloon,
- wherein the constraining structure comprises an expanded diameter smaller than an inflated diameter of the balloon, and
- wherein the constraining structure comprises a plurality of compartments configured to define a plurality of portions of the balloon to expand independently of each other.
A constraining structure for constraining expansion of an inflatable balloon, the constraining structure comprising
- one or more expandable radial rings;
- and
- one or more longitudinal struts connecting the constraining rings,
- wherein the constraining structure is configured to be non deployably positioned over a balloon catheter.
A method for deploying a balloon catheter, the method comprising
- Providing a balloon catheter having a constraining structure mounted over the balloon;
- advancing the balloon catheter to a target site in a vessel of a patient;
- and
- inflating the balloon thereby causing dilation of the vessel in a predetermined non-cylindrical topography.
