Guide catheter occlusion balloon with active inflation

摘要

Various embodiments concern a guide catheter for delivery of an implantable lead within the coronary vein. Such a guide catheter can comprise a tubular body having a main lumen and at least one preformed bend. The tubular body can comprise a liner defining an inner surface, braiding circumferentially surrounding the liner, a jacket covering the braiding and defining an exterior surface of the tubular body, and a plurality of inflation tubes embedded within the jacket. The guide catheter can include a balloon mounted on the tubular body, each of the plurality of inflation tubes in communication with the balloon. The guide catheter can further include a hub providing access to the main lumen, the hub comprising a first port for introduction of contrast media into the main lumen and a second port in communication with the plurality of inflation tubes.
