CATHETER GUIDEWIRE APPARATUS WITH LOCATION SPECIFIC FLEXIBILITY

摘要

A catheter/guidewire for threading into a vasculature passageway includes an elongate body dimensioned for threading into the passageway, where the body has one or more sections intermediate the proximal end and distal end, further to be more flexible than other intermediate sections so that the more flexible sections coincide with curves in the passageway when the elongate body is threaded into the passageway.
