Claim 23:
24. A method for endoluminal intervention at a target site in a patient's vasculature, the method comprising:
advancing a distal braided section of an outer catheter tube in an unexpanded state to the target site in the patient's vasculature, 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; and
pulling the inner push tube proximally to cause, via the spring element, the distal braided section to transition from the unexpanded state to a radially expanded state at the target site in the patient's vasculature.
