Abstract
An apparatus for performing a medical procedure includes a balloon with a variable profile. The balloon includes at least one inflatable chamber occupied by a fluid, such as air, and solids, such as generally spherical balls. When the chamber is inflated, the solids are spaced apart as a result of their ability to move or flow, but when the chamber is evacuated, the solids become compacted and prevent it from fully collapsing. The balloon may have a plurality of inflatable chambers with solids in different arrangements to achieve different objectives during the medical procedure, such as for example stent deployment. For example, one chamber may be expanded while the other is restrained to alter the balloon geometry, such as for providing focused force or permitting perfusion.
