Hierarchical multiscale electrospun scaffold for the regeneration and/or replacement of the tendinous/ligamentous tissue and a method for its production

A multiscale hierarchical scaffold for replacing, repairing, regenerating, reconstructing or simulating a tissue, in particular the tendinous and/or ligamentous and/or muscular and/or nervous tissue comprising:

• (a) a plurality of clusters obtained by electrospinning each one consisting of nanofibers, wherein said plurality of clusters are arranged in order to form one single group;
• and
• (b) a porous sheath obtained by electrospinning consisting of nanofibers, wherein said sheath externally coats and compacts said plurality of clusters keeping them aligned with each other.
