Abstract
A device for supporting the outlet end portion of an intravascular catheter within a blood vessel while a treating agent is delivered into the blood stream through an orifice at the tip. The device comprises a frame having a plurality of radially outwardly projecting frame elements in the form of elongated wire struts extending lengthwise of the catheter. Each wire strut has a generally V-shaped radially outwardly projecting mid-portion, with the apex of the V-shaped mid-portion adapted to rest on the wall of the blood vessel. The distal ends of the wire struts are affixed to the catheter. The proximal ends are longitudinally sidable in grooves in the catheter. The grooves are long enough to accommodate the wire struts when flattened somewhat to pass through narrower blood vessels or when flattened completely for storage in a tube shelter.
