VBR Spinal System
DESCRIPTION
The VBR (Vertebral Body Replacement) System consists of
the BENGAL™ Stackable and OCELOT
®
Stackable Cage
Systems, the BENGAL™, COUGAR
®
, LEOPARD
®
, and
CONCORDE™ Carbon-Fiber Composite VBR Systems, and
the Surgical Titanium Mesh, DEVEX
®
Mesh and X-MESH
®
Expandable Cage Systems. The VBR Spinal Systems are
designed to restore the biomechanical integrity of the
anterior, middle and posterior spinal column even in the
absence of fusion for a prolonged period, as well as for
treating fractures of the thoracic and lumbar spine.
The structure of the carbon-fiber composite implants has
been shown to support anticipated loads with a modulus of
elasticity approximating that of cortical bone. The implants
have ridges or teeth in both the anterior-posterior and
medial-lateral directions, which resist rotation and migration.
The polymer/carbon-fiber composite implants have cavities
to accept packing of bone graft. The entire structure is
radiolucent so that healing can be assessed by normal
radiographic methods. Additionally, radiotherapy can be
performed immediately after surgery.
STACKABLE CAGE SYSTEM
The Stackable Cage System consists of the BENGAL
Stackable and OCELOT Stackable Cage Systems. These
implants are made of a polymer/carbon-fiber composite.
These radiolucent implants are designed with ridges or teeth
to resist rotation and migration, and with cavities to accept
packing of bone graft materials. The carbon-fiber implants
are available in a variety of sizes.
The BENGAL Stackable Cage System consists of both one
piece (monolithic) and two- to three-piece (stackable)
vertebral body replacement components and a supplemental
internal fixation system that offer a variety of size options to
allow surgeons to achieve a desired height. The two- or
three-piece (stackable) construct can be assembled from a
variety of different sized components. A titanium alloy screw
is then passed through a hole in the cages and with a nut
provides a rigid and compressed assembly.
The OCELOT Stackable Cage System consists of one or
more stackable vertebral body replacement compo nents and
a supplemental internal fixation system. One or more
OCELOT Stackable Cage System implants may be stacked to
the desired height, as determined by the surgeon. A titanium
alloy screw can be passed through a center hole in the cages
and with a nut provide a rigid and compressed assembly.
CARBON-FIBER COMPOSITE VBR
SPINAL SYSTEM
The carbon-fiber composite VBR System consists of four
implant systems, the BENGAL, COUGAR, LEOPARD, and
CONCORDE. These implants are made of a polymer/
carbon-fiber composite. These radiolucent implants are
designed with ridges or teeth to resist rotation and migra-
tion, and with cavities to accept packing of bone graft. The
carbon-fiber implants are available in a variety of sizes.
The CONCORDE implants may be utilized in either an open
or minimally invasive surgical approach.
SURGICAL TITANIUM MESH, DEVEX SURGICAL
TITANIUM MESH AND X-MESH EXPANDABLE
CAGE SYSTEMS
The Surgical Titanium Mesh System is designed to restore
biomechanical integrity throughout the thoracic and lumbar
spine following vertebrectomy or corpectomy for patients with
spine tumors or fractures. The system provides anterior,
middle and posterior vertebral column support both
immediately after surgery and for prolonged periods in the
absence of bone fusion.
The Surgical Titanium Mesh System consists of various
shapes and sizes of mesh, standard or angled rings and
screws, endplates, and endcaps. The surgeons have the
option to place the standard or angled rings and screws,
endplates and endcaps within the mesh. These interface
devices may be used to provide increased surface area at
the Mesh/bone interface, which provides additional support
and increased resistance to subsidence.
Surgical Titanium Mesh may be trimmed to the desired
height, as determined by the surgeon. The “teeth” at the
ends of the mesh, resulting from the diamond shaped
perforations, help anchor the device.
The DEVEX implants are designed with ridges or teeth to
resist rotation and migration, and with cavities to accept
packing of bone graft. The DEVEX implants are available in
a variety of sizes.
The X-MESH Expandable Cage System is available in many
heights, and different endplate shapes, sizes and angles.
The surgeons have the option to place the standard or
angled endplates. The “teeth” on the endplates help anchor
the device. The surgeons should use the size and angle that
best fits the defect being treated.
INDICATIONS
Caution: USA Law restricts this device to sale by or on the
order of a physician.
The VBR Spinal Systems are indicated for use in the
thoracolumbar spine (i.e., T1 to L5) to replace a diseased
