Catheter systems provide blood flow paths past a stenotic region of a blood vessel receiving treatment to restore acceptable blood flow. A catheter includes distal and proximal side orifices into a main lumen to provide a blood flow path through the catheter across the stenosis. A segmented or lobed balloon forms blood flow passages between the catheter and blood vessel wall to provide blood flow past the stenosis while the balloon is inflated. Superselective catheter systems provide means for inserting a catheter into coronary arteries remote from the aorta.
A method of administering an angioplasty treatment to a patient to produce acceptable blood flow in a stenotic region of a coronary artery having restricted blood flow, comprising: inserting a tube having an outer surface enclosing a main lumen terminating in a main axial orifice into said coronary
A method of administering an angioplasty treatment to a patient to produce acceptable blood flow in a stenotic region of a coronary artery having restricted blood flow, comprising: inserting a tube having an outer surface enclosing a main lumen terminating in a main axial orifice into said coronary artery, said tube having a proximal portion and a distal portion; inflating a balloon attached to the outer surface of said tube between said proximal portion and said distal portion to compress said stenotic region; channeling blood flow through the wall of said proximal portion of said main lumen immediately adjacent said balloon to fluidly connect locations within said coronary artery surrounding said proximal and distal portions of said tube while said balloon is inflated within said coronary artery to conduct blood downstream from the portion of said coronary artery occluded by the inflated balloon.
