Abstract

Systems and methods provide greater control over the placement of cement and other flowable liquids into bone.

Claims14

Dependent claims

A method of treating bone comprising

inserting an insertion device having an axis percutaneously into a vertebral body having a cortical wall enclosing a cancellous bone volume,
inserting a cavity-forming device through the insertion device into an area of the cancellous bone volume in the vertebral body,
manipulating the cavity-forming device to form a cavity in the cancellous bone volume, the cavity being void of cancellous bone,
inserting a tool through the insertion device into the cavity, the tool having a flexible dispensing end devoid of elastic, shape-memory material and being sized and configured for placement within the cavity to dispense a volume of filling material in the cavity,
coupling to the dispensing end a portion of elongated flexible steering structure, the steering structure being devoid of elastic shape-memory material, and
dispensing a volume of filler material into the cavity through the dispensing end including causing deflection of the dispensing end of the tool within the cavity using the steering structure.
