摘要

A guiding catheter system employs an outer jacket with one or more inflation lumens provided along the length of the jacket. The lumens are in fluid communication with one or more fluted balloons mounted at a distal end of the outer jacket. A torquable stylet is movably disposed within an open lumen of the outer jacket. A guidewire is movably disposed in an open lumen of the torquable stylet. The outer jacket can be provided with break-away features allowing the jacket to be peeled off of a pacing lead.
