摘要:
An aspiration catheter can be used to capture and retrieve vascular debris from blood vessels. The aspiration catheter can include a distal segment having ports positioned along its longitudinal length and about its circumference. The distal segment can capture thrombus at least partially on an exterior of the distal segment when aspiration is applied through the ports, and retrieve the thrombus when the elongate member is retracted proximally. The distal segment can be modified from a non-collapsed configuration to a collapsed configuration when aspiration is applied through the ports. The distal segment can have projections arranged along and around its circumference. The projections can be configured to slide distally through a thrombus within a blood vessel and to pull the thrombus when the elongate member is retracted proximally.
