The first 100% PEEK cranial fixation device

Cranial LOOP is the first-ever cranial fixation device totally made of PEEK.

With its small size (12 mm diameter), the 2nd generation of Cranial LOOP is ideal to strongly fix the bone flap through the craniotomy gap, and at the same time minimize the amount of implanted material, particularly in the epidural region.

• Instrument-free

Cranial LOOP is implanted with no additional instruments. Its unique design makes it a self-cutting device. The surgeon totally controls the bone flap fixation, which is achieved through its fast and easy "pull-and-tighten" action. Using three Cranial LOOPs, a standard bone flap is fixed in less than a minute.

• CT / MRI Artifact-free

Cranial LOOP is totally made of PEEK-OPTIMA®. This makes it completely artifact-free in different medical imaging systems, such as X-rays, CT scanning and MRI.

• High Strength and Safety

NEOS' engineers have developed a unique design which guarantees that Cranial LOOP provides the same fixation strength as similar metallic non-instrument-free cranial fixation devices.

The 2nd generation of Cranial LOOP has been designed to resist the same forces as equivalent titanium devices. The graph above compares the behaviour of Cranial LOOP and homologous systems in a test in which a bone flap was sank 2 mm into the skull (maximum limit tolerated in vivo).

Furthermore, Cranial LOOP shows excellent behaviour at impact, thanks to its inherent elasticity and flexibility.

• 3D Adaptation

Cranial LOOP perfectly adapts to the shape and curvature of the skull, thus guaranteeing the minimal possible profile at both the epidural and epicranial surfaces of the skull.

• Product combination

All members of the Cranial LOOP family can be used either in combination or stand-alone. Thus, neurosurgeons can combine them in the way that best fits each specific craniotomy.
