Methods and apparatus for treating vertebral fractures

摘要

Methods and apparatus for treating bones, including, in one or more embodiments, methods and apparatus for treatment of vertebral fractures that include an inflation device for cavity creation and an inflation and containment device for maintaining vertebral height and cement containment. Methods for treating a bone comprising: creating a cavity in the bone; inflating a containment jacket in the cavity; inflating a balloon within the containment jacket so that the balloon occupies a first portion of the containment jacket; introducing a first filler material into a second portion of the containment jacket, wherein the second portion of the containment jacket is not occupied by the balloon; removing the balloon from the containment jacket; and introducing a second filler material into the first portion of the containment jacket.

1. A method for treating a bone comprising:
inserting a cavity creation balloon in the bone; inflating the cavity creation balloon in the bone to a portion of the bone and create a cavity in the bone; removing the cavity creation balloon from the bone; inserting an inflation and containment device, wherein the device comprises:
a containment jacket;a fill tube comprising a distal end; anda second balloon within the containment jacket so that the second balloon occupies a first portion of the containment jacket, wherein the second balloon extends from the distal end of the fill tube;inflating the second balloon within the containment jacket;introducing a first filler material into a second portion of the containment jacket, wherein the second portion of the containment jacket is not occupied by the second balloon; allowing the first filler material to substantially cure; removing the second balloon from the first portion of the containment jacket after the first filler material has substantially cured; and introducing a second filler material into the first portion of the containment jacket, wherein the second filler material is introduced via the fill tube, and wherein the filler material within the containment jacket interdigitates with cancellous bone.
