A curved inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft extends between opposite first and second end. The inner shaft defines a lumen. The inner shaft is curved between the first end and the second end. A first leg of a balloon is coupled to the outer shaft and a second leg of the balloon is coupled to the inner shaft such that a material can flow through the lumen and into the balloon to inflate the balloon. The balloon includes a wall having a variable thickness between the legs when the balloon is uninflated and a uniform thickness between the legs when the balloon is inflated. Kits, systems and methods are disclosed.

A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.

Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

An inflatable central distractor is inserted in to a disc space between two vertebral endplates. A perimeter balloon is inserted into the disc space in such a manner as to surround the central inflatable distractor. The perimeter balloon and the central inflatable distractor are simultaneously expanded such that as the central inflatable distractor expands the perimeter balloon surrounds the central inflatable distractor and such that the central inflatable distractor and the perimeter balloon, when expanded, contribute to forcing adjacent vertebral endplates apart.

A balloon kyphoplasty surgical device including an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement.

Catheter system, devices and methods for diagnosing and treating lateral stenosis causing back pain and or leg pain. The devices comprise a tubular part for insertion into a working cannula to self-position itself safely within the foramen, and minimize the risk of displacement medially or laterally, to prevent nerve or dura injury. An expandable membrane is configured to maintain the catheter device within the foramen. Expansion of this membrane would decompress the nerve within the foramen by opening the foraminal canal as the membrane expands.

The present invention concerns to a method, a percutaneous access path providing device and a kit of instruments for the treatment of fractured vertebrae, in particular for treating spinal compression fractures in humans. In particular the invention concerns to a percutaneous access path providing device comprising a vertebra access cannula and a vertebra introducer stylet, wherein the vertebra introducer stylet has a tip.

A method of treating a bone of a patient includes identifying a portion of the patient to be protected. A cannula is provided that includes a shaft extending between opposite first and second end surfaces. The shaft incudes an inner surface defining a lumen. The cannula includes a scoop extending from the second end surface. The scoop includes an inner surface that is continuous with the inner surface of the shaft and an opposite outer surface. The cannula is inserted into the bone such that the outer surface of the scoop is positioned adjacent to the portion of the patient to be protected. A balloon is inserted into the cannula such that the balloon is positioned within the scoop. The balloon is inflated such that the balloon expands away from the scoop as the balloon is inflated and creates a void in the bone. Systems are disclosed.

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.

An inflatable central distractor is inserted in to a disc space between two vertebral endplates. A perimeter balloon is inserted into the disc space in such a manner as to surround the central inflatable distractor. The perimeter balloon and the central inflatable distractor are simultaneously expanded such that as the central inflatable distractor expands the perimeter balloon surrounds the central inflatable distractor and such that the central inflatable distractor and the perimeter balloon, when expanded, contribute to forcing adjacent vertebral endplates apart.
