IMPLANTS AND METHOD FOR FORMING AN IMPLANT

WIPO Patent Application WO/2022/018124

A3

Embodiments herein relate to a three-dimensional implant for tissue reconstruction or tissue augmentation for insertion into a patient. The implant comprises a plurality of strands forming a three-dimensional structure, which comprises a plurality of hollow channels. Each hollow channel comprises a plurality of sidewalls. A sidewall comprises a plurality of strand segments and a plurality of gaps arranged altematingly so that a gap is formed between adjacent strand segments of the sidewall. The gap comprises a gap length (gl) and a resting gap height (gh). The plurality of gaps are reversibly expandable gaps. Adjacent strand segments comprise a deflection capability (δ) based on an object to be received by the reversibly expandable gap. A radius (R) of the plurality of strands and a gap lengths (gl) of a reversibly expandable gap is based on a yield strength (δyield), the elastic modulus (E) of the material and a deflection capability δ of the adjacent strand segments forming the reversibly expandable gap.
