Inflatable device for use in surgical protocol relating to fixation of bone
First Claim
1. A device for compacting cancellous bone comprisinga support tube, a first expandable body and a second expandable body carried by the support tube, each expandable body having a collapsed geometry permitting the first and second expandable bodies to be simultaneously deployed inside a bone, and a common flow channel in the support tube communicating jointly with each expandable body and adapted to be coupled to a source of an expansion medium to convey the expansion medium simultaneously into the first and second expandable bodies to cause simultaneous expansion of both expandable bodies inside bone to compact cancellous bone.

Abstract
A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone) against the inner cortex of bones whether the bones are fractured or not. The balloon comprises an inflatable, non-expandable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon is prevented from applying excessive pressure to the outer cortical bone. The wall or walls of the balloon are such that proper inflation the balloon body is achieved to provide for optimum compression of all the bone marrow. The balloon is able to be folded so that it can be inserted quickly into a bone. The balloon can be made to have a suction catheter. The main purpose of the balloon is the forming or enlarging of a cavity or passage in a bone, especially in, but not limited to, vertebral bodies.
