Document Type and Number:
WIPO Patent Application WO/2022/074427
Kind Code:
A1
Abstract:
An implantable and biodegradable polymeric matrix (10) with reduced foreign body response for the regeneration and/or reconstruction and/or creation of soft and connective tissue and/or organs has: a density equal to or lower than 40 kg/m 3; a plurality of local thicknesses of a solid component (12), with an arithmetic mean equal to or lower than 95 μm, an average size of pores/void spaces (11) equal to or lower than 15,000 μm; a surface roughness R a of the solid component (12) with an arithmetic mean equal to or lower than 3 μm; a contact angle θ of the solid component (12) lower than 110°, preferably in the range 10° to 90° and more preferably in the range 30° to 60°.
