1. A method for neurovascular endoluminal intervention to remove one or more clots in a patient's neurovasculature, the method comprising:
advancing a distal braided section of an outer catheter tube in an unexpanded state to one or more clots in the patient's neurovasculature, the outer catheter tube comprising a proximal section, wherein an inner push tube extends through the proximal section and the distal braided section during the advancing, the inner push tube coupled to the distal braided section to push and extend the distal braided section to stretch longitudinally and contract radially to the unexpanded state, wherein the inner push tube is coupled to the distal braided section via a spring element coupled to the distal braided section;
actuating the inner push tube to cause the distal braided section to transition from the unexpanded state to a radially expanded state; and
removing the one or more clots through the outer catheter tube while the distal braided section is in the radially expanded state.
