The Vista®-S Device is manufactured wholly from unfilled
PEEK-OPTIMA® LT1, a polyetheretherketone. This material is
a thermoplastic polycondensate, semicrystaline polymer. It is used in
this device in the unfilled state (i.e. no glass or carbon fiber
fill). Due to the radiolucent nature of PEEK-OPTIMA® LT1,
three radiopaque markers made of tantalum are incorporated into the
device to indicate the nose end and the superior and inferior corners
of the opposite end for use in postoperative monitoring of device position.
The superior and inferior surfaces of the device have a textured
surface to provide increased stability. The device is available in a
variety of cross-sectional geometries and sizes. These implants offer
two different included angle options to maintain the natural contour
of the spine.
These implants are intended for single use only and must not be
reused under any circumstances. Surgical instruments are also
available to assist in the implantation of the device.
