Recent Data Show Positive Outcomes of Penumbra’s BENCHMARK™ BMX®81 System for Radial Access during Neurovascular Interventions

Recent data support the use of Penumbra’s BENCHMARK BMX81 Access System for radial access in neurovascular interventions, including expanding snuffbox access for carotid artery stenting to a wider patient population and successful navigation to target locations. The data were presented during the Society of NeuroInterventional Surgery (SNIS) Annual Meeting.

• Expanding radial access to more patients with reduced rates of radial artery occlusion: Researchers from John Muir Health and East Bay Brain and Spine looked at cervical carotid stenting via transradial access. The abstract, Snuffbox access for carotid artery stenting using the BMX-81 guide catheter: technical and anatomic considerations¹, reported that the “…7 French BMX-81 guide catheter provides a balance between flexibility and rigidity that has advanced the ease and capability of radial access procedures best appreciated with carotid stenting.” The paper concluded that the BMX81 catheter can provide snuffbox access to a wider population and reduce rates of radial artery occlusion. Also, it noted that BMX81 helped overcome technical challenges, such as acute carotid origin angles and lower carotid bifurcations with shorter common carotid artery lengths, associated with carotid stenting.
• Offering ease of use and versatility for wide variety of procedures: Data presented by researchers from Vancouver General Hospital and Dalhousie University suggest that BMX81 is safer with improved maneuverability and support for a wide range of procedures. The abstract, Practical uses of the BENCHMARK BMX81 in the road less travelled: radial access for neurovascular intervention², highlighted early multicenter institutional experience with the guiding catheter. The paper reported that the BMX®81 was successful in the navigation of the anatomy to the target location in 95% of cases in the series and no radial access or BMX®81 related complications were identified. Additionally, the authors commented in the accompanying manuscript³ that “… the one-piece design of the BMX®81 laser-cut stainless steel hypotube offers an advantage over traditional guide catheters by providing superior column strength and support. Distally, the design provides a construct with kink resistance, deliverability, and support.”

BMX81 is designed for a variety of procedures, including the most complex neurovascular interventions. The recent data continues to show that the advanced stainless steel hypotube technology of BMX81 provides distal deliverability and proximal stability for most complex therapies.
