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
Which implants and approach are appropriate is determined by the operating neurosurgeon or spine surgeon based on the pathology and anatomy. After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh. Minimally invasive techniques, including percutaneous pedicle screw placement and percutaneous disc decompression, aim to achieve these goals through smaller corridors.
SpineNav MIS Pedicle Screw System: Overview
Minimally invasive percutaneous pedicle screw system referenced in INVAMED's article on minimally invasive spine surgery techniques (no standalone product page found during this crawl; URL given is the referencing article). Pedicle screws anchor into the vertebral body through the pedicle corridor, enabling shorter constructs and improved biomechanical control.
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. Cranial implants use biocompatible metals such as titanium and platinum, chosen in part for their imaging compatibility and long-term tissue tolerance. Percutaneous disc decompression uses minimally invasive mechanical or radiofrequency techniques to reduce intradiscal pressure in contained disc herniations.
Key Considerations
- Pedicle-screw trajectory accuracy is important to remain within the bony pedicle, motivating the use of fluoroscopy or navigation.
- Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes.
- All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU.
Frequently Asked Questions
Are these neuro and spine devices CE marked?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
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.
Clinical and Technical Context
Minimally invasive techniques, including percutaneous pedicle screw placement and percutaneous disc decompression, aim to achieve these goals through smaller corridors. The use and interpretation of monitoring are handled by the surgical and monitoring team. Percutaneous disc decompression is reserved for selected contained herniations as judged by the clinician. INVAMED's Stella Cranial Platinum Plate is a platinum cranial plate used for craniotomy closure, skull reconstruction, and neurosurgical fixation, described with a 3D-technology patient-anatomy fit. Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes. Plate choice and configuration are determined by the neurosurgeon for the specific reconstruction. Cage material, size, and lordosis are selected by the surgeon according to the disc space and fusion goals. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. INVAMED lists intraoperative neuromonitoring among the tools in its neuro, spine, and cranial portfolio. Whether a patient is a candidate for disc decompression is determined by the treating 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. INVAMED's SpineNav MIS Pedicle Screw System is positioned for pedicle-screw fixation, including minimally invasive placement, within the spinal line.
