Merit Medical Systems, Inc. announced the expansion of its Maestro Microcatheter product line to now include a new longer length for radial embolization procedures. The Maestro is part of a comprehensive offering of embolotherapy solutions, which includes Embosphere®? Microspheres, the most widely studied and clinically utilized round embolic on the market.

Embolization is a minimally invasive procedure that blocks one or more blood vessels or abnormal vascular channels to treat a number of clinical conditions. The new 165-cm Maestro length will be available in 2.1F, 2.4F, 2.8F, and 2.9Fcatheter diameters to support a broad range of embolization procedures. TheMaestro Microcatheter is compatible with coils up to 0.018" and embolic up to and including 900 um.

Three tip designs are available, including a swan neck designed to seat the catheter in the vessel, reducing the recovering effect of the microcatheter as embolic is delivered. A hydrophilic coating aids in smooth tracking through tortuous anatomy. Merit is a market leader in radial access with a portfolio that includes the recently launched PreludeSYNC EZ??

Radial Compression Device, PreludeSYNC Distal?? Radial Compression device, and Prelude IDeal?? Hydrophilic Sheath Introducer.

Radial artery access is a minimally invasive approach to diagnosing and treating a wide range of medical conditions. Through a small hole in the wrist, a catheter is inserted into the radial artery. Under imaging guidance, the catheter is then threaded through the body's network of blood vessels to the location needing treatment.

Compared to femoral access procedures, or those performed through the femoral artery in the groin, benefits of radial access include fewer bleeding complications, improved patient comfort, and decreased procedure costs.
