Benefits of technology

[0010]In some embodiments, the bone support device can comprise a structure that when deployed can extend between the superior endplate and the inferior endplate in a vertebral body. In this manner, a load placed on the superior endplate can be transferred through the device to the inferior endplate to provide structural support to the superior endplate. In certain embodiments, the bone support device can comprise a structure that when deployed can contact the endplate and both the cortical bone in the vertebral body side wall and the cortical bone in the inferior endplate. Such a configuration can provide structural support to the superior endplate by transferring a load from the superior endplate to both the vertebral body side wall and the inferior endplate.
[0015]Some embodiments of a bone barrier device of the present invention can comprise a barrier material that can be inserted into the interior of a bone and adapted to prohibit substantially all of a bone filler material inserted into the bone from flowing through and / or around the barrier material. Such embodiments of a barrier material may prevent the undesirable flow of the bone filler material into and through a compromised portion of the bone. For example, an embodiment of a such a barrier material inserted into a void created in the interior of a vertebral body may prevent the flow of subsequently injected bone cement through and / or around the barrier material into a compromised endplate and / or vertebral body wall. In this manner, the barrier material may prevent leakage of the bone cement through the endplate and / or vertebral body wall. Such embodiments of a barrier material may be utilized without any other structural supports. Some embodiments of a bone barrier device can comprise a barrier material having an open weave, mesh, and / or through hole design adapted to reduce the flow, and to allow some flow, of bone filler material through and / or around the barrier material.

Problems solved by technology

Bone may become fractured or prone to compression fracture or collapse due to various conditions, including osteoporosis, avascular necrosis, cancer, trauma, or other disease.
If not successfully treated, fractured or weakened bone can result in deformities, chronic complications, and an overall adverse impact upon the quality of life.
These minimally invasive techniques also often require only local anesthesia.
The development of minimally invasive spinal procedures, for example, for repair of vertebral compression fractures, has resulted in reduced recovery time and decreased post-operative pain as such procedures require minimal, if any, muscle dissection and can be performed under local anesthesia.
Moreover, patients who have suffered a VCF may be at risk for additional VCFs.

Embodiment Construction

[0041]Embodiments of the present invention can provide bone support and / or barrier devices, systems, and kits, and methods. Some embodiments are useful for supporting a bony structure in an interior body region in a human or animal accessed utilizing a minimally invasive surgery technique. The devices, systems, kits, and methods can be adapted for use in many suitable interior body regions, wherever the support, repair, and / or protection of one or more layers of tissue may be required for a therapeutic or diagnostic purpose. The illustrative embodiments are associated with devices, systems, kits, and methods used to treat bones. Other embodiments may be utilized in other interior body regions or with other types of tissues.

[0042]As used in this specification and the appended claims, “proximal” is defined as nearer to a point of reference such as an origin, a point of attachment, or the midline of the body. As used in this specification and the appended claims, “distal” is defined as...

Abstract

A bone barrier device can comprise a barrier material that can be inserted into the interior of a bone and adapted to prohibit substantially all of a bone filler material from flowing through and / or around the barrier material into and through a compromised portion of the bone. Such a barrier device may be inserted into a void created in the interior of a vertebral body so as to prevent the flow of bone cement through and / or around the barrier material into a compromised endplate and / or vertebral body wall. The bone barrier device may comprise a barrier material having an open weave, mesh, and / or through hole design adapted to reduce the flow, and to allow some flow, of bone filler material through and / or around the barrier material.

Description

FIELD OF THE INVENTION[0001]The present invention relates to bone support and / or barrier devices and systems, kits comprising a bone support and / or barrier device, and related methods. Embodiments of the present invention can be advantageous for providing support and / or barrier to a bone accessed by a minimally invasive technique or other surgical technique.BACKGROUND OF THE INVENTION[0002]Bone may become fractured or prone to compression fracture or collapse due to various conditions, including osteoporosis, avascular necrosis, cancer, trauma, or other disease. If not successfully treated, fractured or weakened bone can result in deformities, chronic complications, and an overall adverse impact upon the quality of life.[0003]Minimally invasive surgical procedures have been developed that can be used to treat fractured bones. Such minimally invasive procedures can reduce pain, post-operative recovery time, and the destruction of healthy tissue. In minimally invasive surgery, the sit...
