An interspinous process spacer for implantation in an interspinous space between a superior spinous process and an inferior spinous process includes a balloon-like body, a first deployable protrusion and a second deployable protrusion. The body has a distal end, a proximal end and a longitudinal axis extending between the proximal and distal ends. The spacer is arrangeable in an unexpanded configuration and an expanded configuration. The first deployable protrusion is mounted proximate the proximal end and the second deployable protrusion is mounted proximate the distal end. The first and second deployable protrusions are oriented generally parallel to the longitudinal axis in the unexpanded configuration and generally perpendicular to the longitudinal axis in the expanded configuration.

Minimally invasive interspinous process spacer implants and methods

A porous containment device for implanting into the interior volume of a targeted vertebral body for use in restoring the anatomy of the targeted vertebral body. The porous containment device is expandable from an insertion configuration to an expanded configuration via, for example, a bone filler material. The porous containment device includes an enlarged proximal portion, an enlarged distal portion, and a narrower central portion located between the enlarged proximal and distal portions. The porous containment device includes at least one pore positioned between a midline of the narrower central portion and walls of the enlarged distal and proximal portions. The porous containment device may include one or more air or fluid evacuation pores to permit air or fluid to escape and internal or external constraints to form the narrower central portion. In addition, a cannulated sleeve may be used to insert the porous containment device.

Porous containment device and associated method for stabilization of vertebral compression fractures

A minimally invasive system and method for vertebral body augmentation includes an expandable containment device, a chassis including an interior cavity for at least partially enclosing the expandable containment device, a first guidewire, a working cannula, a second guidewire having at least a partially flexible distal end portion and a sleeve for introducing bone filler material through a cannulated passageway of the sleeve and into an interior cavity of the containment device. The containment device preferably includes a plurality of pores for directing the outflow of bone filler material anteriorly within the vertebral body. The containment device and chassis are left interior to the vertebral body subsequent to height restoration and augmentation of the vertebral body.

Minimally invasive spine augmentation and stabilization system and method

The present invention is directed to a porous or permeable containment device for implanting into the interior volume of a targeted vertebral body for use in restoring the anatomy of the targeted vertebral body. The containment device is expandable from an insertion configuration to an expanded configuration via, for example, a bone filler material. The containment device preferably permits the bone filler material to flow out of the containment device via, for example, one or more pores, one or more flow-directing tentacles, etc. so that the bone filler material may interdigitates with the surrounding bone tissue. The containment device is preferably configured to have a pre-determined, 'dog-bone' shape, when in the expanded configuration. The containment device preferably also includes one or more knobs or ribs to facilitate anchoring of the containment device to the surrounding bone tissue, one or more air or fluid evacuation pores to permit air or fluid from escaping from the interior volume of the containment device and/or one or more radiopacity rings or markers to enable a surgeon to locate and/or position the containment device under X-ray imaging.
