Made for all that follows a craniotomy. One solution, endless possibilities.

Beyond the skull

INTRA is a Class IIb medical device, certified under Directive 93/42/EEC since 2021, designed to enable advanced transcranial ultrasound imaging and therapies.

Manufactured from a biocompatible material, it is available in three standard sizes and can be adapted in the sterile field using common surgical instruments.

Key advantages

Compared to other transparent cranial prostheses, INTRA offers:

Superior sonolucency compared to traditional materials
High ultrasonic energy transmission (up to 88%) for clearer, more accurate imaging
Minimal distortion, outperforming materials such as PMMA
Low porosity for optimal acoustic window performance

Clinical applications

INTRA is suitable for any post-craniotomy application, including trauma, stroke, epilepsy, tumors, neuromodulation, neurodegenerative and movement disorders, Chiari malformation decompression, hydrocephalus management, and bypass patency assessment.

Diagnostic
Ultrasound over CT/MRI for follow-up imaging

No radiation, lower costs, faster imaging
Bedside, clinic, and home monitoring
Convenient surveillance for outpatient care
Dynamic assessment in different positions
Easy follow-up, fewer emergency room visits

Therapeutic
Ultrasound-guided treatments

Focused ultrasound for neurosurgery and neuro-oncology
Non-invasive blood–brain barrier opening for targeted, effective drug delivery
Potential therapies for neurodegenerative and movement disorders
