Enabling MRI guided vascular interventions

EmeryGlide

We enable interventions at optimal visibility and gold standard flow without radiation risk.

Nano4Imaging is developing a suite of MRI compatible devices and markers that support common and complicated interventional vascular procedures. Cardiac MRI, Interventional Radiology and Radiotherapy are clinical area´s to benefit from this unique technology that can be employed in any conventional MRI suite*

*Technology has been tested safe up to 3Tesla according to applicable ASTM and ISO standards for heating, torque, and visibility (artefacts)

Clinical perspective

The societal burden of CVD remains high and despite state of the art cathab procedures, MRI based interventional cardiology is expected to bring strong patient and staff benefits. Our vision is to overcome current challenges by our medical devices, marking technology and software solutions to assist guidance.

MR based interventional cardiology

  • Radiation free alternative

  • Higher image resolution

  • Improved target visibility

Challenges

  • MR compatible quidewires limited

  • Inaccurate tracking softwares

  • Lack of enough clinical evidence and high costs

Opportunities

  • Strong clinical push

  • Innovative catheter and guidewire designs

  • Al powered tracking

Guide wires dedicated for MRI

The  EmeryGlide (TM) guidewire is an MRI conditional guide wire which is safe to use in 1.5 and 3.0 Tesla for real-time interventions according to ASTM F2182, F2052, F2053 and F2213 standards. The wire has discrete MRI markers and the entire  wire is radiopaque (ASTM F640-79). In addition its construction with a double internal winding and the entire body and tip are packed into one sleeve to prevent detachment of tip and breaking of the internal  core. The MRWire has CE 0344, FDA 510 K approval and is registered by Health Canada.

Applicable product standard:
sterile, single-use intravascular introducers, dilators and guidewires (ISO/DIS 11070:2013).

MR image (1.5 tesla, GRE) showing discrete markers in the tip and distal from the tip create MRI image artefacts tested by ASTM F2119. The image above shows the artifacts evenly distributed over a guide wire inserted in the right renal artery, followed by balloon dilatation, pull-back of catheter and stenting (large artefact).
