Helical mesh endoprosthesis and methods of use

摘要: A stent comprising a helical mesh coil is provided having substantially rectangular cross section and band width equal at least as great minimum contracted delivery diameter of the stent. The has multiplicity openings forming lattice that preferably provides about 60 % open space or more. Alternative embodiments include free ends preferentially overlap neighboring turns coil, integrally formed barbs enhance resistance to localized compressive forces. Methods deploying also provided.
