A medical filter intended for placement inside a tubular body passage of a patient has a generally longitudinally extending central spine with a retrieval element at one end; and a plurality of filter sections attached to and spaced along the spine, each of the filter sections having a plurality of radial arms attached to the spine and extending radially outwardly with parallel end segments extending axially generally parallel to the longitudinal axis, each of the end segments ending in a tip which extends radially inwardly. Each filter section may also have a graft band attached to the parallel end segments of the radial arms. |
