Claim 0:
1. A reperfusion device for an occluded vessel, the device comprising:
a framework of struts connected by a collar to a shaft having a distal step feature, the struts forming a porous body and a porous inner body flow channel internal to the porous body, the porous inner body flow channel connected to the shaft by a partial collar, the porous body comprising a collapsed delivery configuration stored in a microcatheter and an expanded deployed configuration when delivered to an occlusion and distal of the microcatheter wherein the partial collar is positioned on the shaft proximal to the step feature and within the collar to form a mechanical lock under tension; and
one or more indicator bands disposed on the shaft and configured to indicate when a distal end of the shaft is approaching the distal end of the microcatheter, wherein the one or more indicator bands are recessed below a surface of the shaft to provide a tactile feedback;
the framework of struts being constructed from a material visible under fluoroscopy and recovering its shape in the expanded deployed configuration automatically once released from the collapsed delivery configuration.
