This is a technical overview of an INVAMED device within the neuro, spine & cranial portfolio. Minimally invasive techniques, including percutaneous pedicle screw placement and percutaneous disc decompression, aim to achieve these goals through smaller corridors. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Neurosurgical Fixation and Spinal Decompression
Minimally invasive techniques, including percutaneous pedicle screw placement and percutaneous disc decompression, aim to achieve these goals through smaller corridors. Which implants and approach are appropriate is determined by the operating neurosurgeon or spine surgeon based on the pathology and anatomy. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion.
Stella Cranial Platinum Plate: Overview
A platinum cranial fixation system for neurosurgical craniotomies, providing superior biocompatibility and reliable stability in skull reconstructions or tumor resections (official meta description). Per invamed.com content: represents cranial repair technology utilizing 3D technology to ensure a perfect fit and optimal support tailored to patient anatomy; plates and screws can be configured for rigid or semi-rigid fixation to realign and stabilize bone flaps or skull fragments and preserve cranial vault integrity.

How It Works and Where It Fits
INVAMED's neuro, spine, and cranial line spans cranial fixation, pedicle-screw stabilization, interbody fusion, and adjunct agents used in these procedures. Intraoperative neuromonitoring tracks nerve and spinal cord signals during surgery to help the team detect changes that could indicate risk to neural structures. Cranial implants use biocompatible metals such as titanium and platinum, chosen in part for their imaging compatibility and long-term tissue tolerance.
Key Considerations
- Interbody cage material and dimensions are matched to the disc space, desired lordosis, and fusion strategy.
- Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes.
- Cranial implant material is chosen in part for imaging compatibility and low profile, with platinum and titanium being common options.
Frequently Asked Questions
What is the INVAMED pedicle screw system called?
INVAMED's pedicle-screw system is the SpineNav MIS Pedicle Screw System, positioned for spinal fixation including minimally invasive placement.
Are titanium cranial plates MRI compatible?
Titanium cranial implants are typically MR Conditional; the specific scanning conditions are stated in the device instructions for use, and imaging staff should be informed of any implant.
Who decides which spinal implant to use?
The operating spine surgeon selects implants based on the pathology and anatomy; this article is educational and not a treatment recommendation.
About INVAMED
INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
Plate choice and configuration are determined by the neurosurgeon for the specific reconstruction. Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes. Minimally invasive techniques, including percutaneous pedicle screw placement and percutaneous disc decompression, aim to achieve these goals through smaller corridors. Cage material, size, and lordosis are selected by the surgeon according to the disc space and fusion goals. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content. Percutaneous disc decompression is reserved for selected contained herniations as judged by the clinician. After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh. Whether a patient is a candidate for disc decompression is determined by the treating clinician.
