MicroVention Enters Transradial Access Therapy; Receives FDA Clearance of SOFIA™ EX 5F 115cm Intracranial Support Catheter

Aliso Viejo, California, September 21,2023 – MicroVention, Inc., a global neurovascular company and wholly owned subsidiary of Terumo Corporation, today announced that the SOFIA™ EX 5F 115 cm Intracranial Support Catheter (Soft TOrqueable catheter For Intracranial Access) has received FDA 510(k) clearance on September 15, 2023, for transradial access in addition to transfemoral access. The unique design of the SOFIA™ EX 5F Catheter allows for great trackability and a large inside lumen provides a fast and effective way for tracking to intracranial locations in patients. Reinforced with a nitinol coil and stainless-steel braid, SOFIA™ EX offers support and kink resistance. The catheter has an inner PTFE liner throughout the entire length with 12 transition zones optimized for pushability.

Transradial access utilizes the radial artery in the wrist as opposed to the femoral artery in the groin in transfemoral access. The SOFIA™ EX 5F radial access clearance proudly marks MicroVention’s first radial access product and signifies our commitment to innovation. MicroVention believes providers should have the ability to feel confident in our SOFIA™ EX 5F in either the transradial or transfemoral access approach.

“We are pleased to receive FDA clearance for MicroVention’s SOFIA™ EX 5F Intracranial Support Catheter for transradial access,” said Carsten Schroeder, CEO, MicroVention. “This achievement signifies our commitment to radial neurointervention and represents our unwavering commitment to improving healthcare and helping to save patient lives, while striving to be at the forefront of innovation.”
