Abstract
A catheter assembly can include a cannula disposed at a distal portion of the catheter assembly. The cannula can have a collapsed configuration and an expanded configuration. The cannula can be arranged to permit the flow of blood therethrough when in the expanded configuration. The catheter assembly can comprise a tip member coupled with a distal portion of the cannula. A guide feature can be configured to receive a guidewire through a guide lumen formed through the guide feature. The catheter assembly can be configured such that, when the catheter assembly is inserted into a patient with the guidewire, the guidewire passes through the guide lumen and along at least a portion of an outer surface of the catheter assembly.
