Pushability. Trackability. Flexibility.

During embolization procedures, having a reliable microcatheter will enhance the efficiency of the procedure and provide the outcomes you expect for small vessel embolization.

Hydrophilic Coating Distal

Increases trackability through tortuous anatomy.

Merit Maestro Hydrophilic Coating
Merit Maestro Nylon Ribbon Braiding

Nylon Ribbon Braiding

Proprietary nylon braiding provides excellent pushability, trackability and kink recovery when crossing small tortuous vessels.

Flexible Distal Region

Designed for atraumatic vessel entry

Merit Maestro Swan Neck Design

Swan Neck Design

Once the Swan Neck catheter tip is in position in the vessel, the secondary curve helps seat the catheter in the vessel reducing the recoiling effect of the embolic agent as it is introduced.
