Temporary occlusions balloon devices and methods for preventing blood flow through a vascular perforation
First Claim
1. An expandable member for occluding a perforation in a blood vessel, the expandable member comprising:
- a first balloon having a first stiffness and containing a first composition;
a second balloon having a second stiffness and containing a second composition; and
a third balloon having a third stiffness, the third balloon being disposed between the first balloon and the second balloon, wherein the third stiffness is less than the first stiffness and the second stiffness, and whereupon expanding the third balloon causes the first balloon and the second balloon to release substantially simultaneously the first composition and the second composition to allow combining of the first composition and the second composition to form in-situ a biocompatible foam.

Abstract
A device for occluding a perforation in a blood vessel includes an expandable member. The expandable member includes a central expandable balloon disposed between a proximal and a distal balloon, wherein the proximal and distal balloons each contain first and second compositions, respectively. The proximal, central and distal balloons have respective stiffnesses, and the central balloon has a third stiffness that is less than the first and second stiffnesses. Upon expansion, the central balloon causes the proximal balloon and the distal balloon to substantially simultaneously release the first and second compositions, thereby allowing the first composition and the second composition to combine in-situ and form, therein, a biocompatible foam to occlude a perforation within the vasculature.
