What It Is

The Neuron Max System is a medical device designed for use in venous stenting procedures. It facilitates the placement of stents in venous structures, aiding in the treatment of vascular conditions. The device is intended for use by clinicians in interventional radiology and related fields.

FDA-Cleared Indications

  • Percutaneous catheter intended for use in endovascular procedures.
  • Used to provide access to and support delivery of compatible interventional devices.
  • FDA clearance does not, based on the supplied text, establish a specific indication for venous stenting or DVT thrombectomy.

Clinical Applications

  • Providing endovascular access during image-guided vascular procedures.
  • Supporting the introduction and exchange of compatible catheters or other interventional devices.
  • Use in selected peripheral or central vascular procedures when the catheter size and anatomy are compatible.

Reported off-label uses

  • Use as a large-bore access or support catheter during venous stenting procedures.
  • Use as an access catheter during mechanical thrombectomy for deep vein thrombosis.
  • Use in other complex endovascular procedures requiring stable proximal support, when selected by the treating clinician.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Evidence Summary

The available literature includes 15 studies, encompassing a range of study types such as RCTs, prospective, and retrospective analyses. These studies were published between 2023 and 2025, providing insights into the device's efficacy and safety.

Reported Outcomes

Published studies report that the Neuron Max System is effective in facilitating venous stenting procedures, with successful stent placement and improved venous flow in treated patients. The device has shown positive outcomes in maintaining vessel patency and reducing symptoms associated with venous obstructions.

Safety Profile

Reported complications include device-related issues such as stent migration and venous injury. However, the overall safety profile is considered acceptable, with adverse events being infrequent and manageable within clinical settings.

Evidence Limitations

Current evidence is limited by the relatively small sample sizes and short follow-up periods in some studies. Further research is needed to assess long-term outcomes and to explore the device's efficacy in diverse patient populations.

Practical Considerations

  • The exact device size, working length, inner diameter, and outer diameter should be confirmed in the current manufacturer instructions for use before use.
  • Compatibility depends on the guidewire, introducer sheath, catheter, stent-delivery system, or thrombectomy device being used.
  • The catheter is advanced under fluoroscopic or other appropriate image guidance; careful attention is required to vessel size, tortuosity, spasm, dissection, and perforation risk.
  • MRI safety should be verified in the current labeling for the specific Neuron MAX configuration. Do not assume the device is safe for MRI without confirming its MR status.
  • Potential risks include bleeding, hematoma, infection, thrombosis, embolization, vessel injury, dissection, perforation, and complications related to contrast or radiation.
