Endolumenal prosthesis

摘要

The present invention relates to an endolumenal prosthesis comprising a tubular body adapted to convert from a contracted condition to an expanded condition. The tubular body develops along a longitudinal axis and comprises: a plurality of coils and at least one bridge. The coils develop along a substantially circumferential direction and the bridge connects two coils. The coils are realized in a persistent material, while the bridge is realized in a bioabsorbable material.

1. An endolumenal prosthesis, comprising a tubular body adapted to convert from a contracted condition to an expanded condition, said tubular body being developed along a longitudinal axis, said tubular body comprising:
a plurality of coils made of a non-bioabsorbable material that develop in a substantially circumferential direction, and at least two bridges connecting two coils of the plurality of coils, the two coils being adjacent to each other along the longitudinal axis, said at least two bridges comprising: at least one bioabsorbable bridge connecting the two coils and made of a bioabsorbable material; and at least one non-bioabsorbable bridge connecting the two coils and made of the non-bioabsorbable material, wherein said at least one non-bioabsorbable bridge and said at least one bioabsorbable bridge are spaced apart from each other along said substantially circumferential direction between the two coils.
