摘要：
A system for bypassing a vascular occlusion includes a catheter, and a puncturing mechanism within the catheter having a sleeve and a puncture wire positioned within the sleeve. The puncture wire is elastically deformable between an access configuration, and a deployed configuration. The puncture wire has a shape memory bias and is retracted within the sleeve and held by the sleeve in opposition to the bias in the access configuration.
