Dynamically curved access tool for complex arch anatomy and radial access

Abstract

The intravascular device includes an elongated outer catheter body having a catheter proximal end, a catheter distal end, and a catheter lumen extending between the catheter proximal end and the catheter distal end. The intravascular device further includes an elongated inner articulation member slidably disposed within the catheter lumen. The inner articulation member has a proximal member end and an articulatable distal member end. The intravascular device further includes a control assembly mechanically coupled to the catheter proximal end and the proximal member end. The control assembly is configured to translate the outer catheter body distally over the inner articulation member to articulate the distal member end.
