摘要

Device (10) configured to treat a defect biological tunnel septa tissue, comprising: a frame (12) flat, resiliently flexible, having a first longitudinal longitudinal end, a second longitudinal end and a shaft (25) extending between said ends; a first anchor (26, 24), a second anchor (26, 24) and a third anchor (24,26), wherein the first anchor and the second anchor are positioned toward the first longitudinal end of the frame, and in the the third anchor is positioned toward the second longitudinal end of the frame, and wherein the first anchor is located opposite the second anchor, and wherein the first anchor, the second anchor and the third anchor are configured to attach to the tissue; a scaffold (14) coupled to the frame D, wherein the compressibility and elasticity of the scaffold enable the scaffold substantially fills the tunnel defect; and wherein the scaffold is configured to promote tissue growth on the scaffolding.
