Abstract
The technical disclosure relates to catheters useful for engaging a vessel from within a lumen defined by the vessel. A catheter includes an elongate shaft, an inflatable balloon disposed on the distal end of the elongate shaft, a guide disposed on the external surface of the balloon, and an engaging member having a distal end releasably secured by the guide such that the guide maintains the engaging member distal end adjacent the outer surface of the balloon when the balloon is in an uninflated configuration but releases the engaging member distal end as the balloon moves from an uninflated configuration to an inflated configuration. The technical disclosure also relates to methods of using a catheter.
