Claim:
1. A method for treating a peripheral arterial disease occlusion in a vasculature below a femoral artery, comprising: gaining access to said vasculature at a first access site below a popliteal artery; pushing a wireguide through said first access site and upstream through said vasculature, said wireguide comprising a circumferential groove adjacent a larger distal end portion; gaining access to a femoral artery at a second access site; pushing a catheter through said second access site and downstream through said femoral artery, said catheter comprising a flared distal end and an elastic catch within an opening defined by said flared distal end; positioning said catheter within said femoral artery or said vasculature such that said flared distal end fills a majority of a diameter thereof at a location upstream from said occlusion in said vasculature; pushing said wireguide upstream through said occlusion; pushing said distal end portion of said wireguide through said opening and said catch of said catheter until said groove of said wireguide receives said catch of said catheter; pulling said catheter upstream through said femoral artery, said catheter thereby pulling said wireguide upstream through said femoral artery with said catheter; pulling said catheter completely out from said second access site, said wireguide thereby being pulled through said second access site while remaining positioned through said occlusion.
