Device for the treatment of constricted vessels

摘要

This invention is directed to a system for implanting a device to open constrictions in corporal conduits, which comprises (a) an elongated tubular member (40) and (b) a spatial spiral (1) of elongate axial extension wound of thin wire and having attachment means at each end, said spiral being positioned on and concentric to said elongated tubular member, said spiral being in a constricted condition such that its lateral profile is smaller than it would be if said spiral were not constricted.
