摘要： A planar porous composite structure including a plurality of regular textile planar layers formed of continuous yarns. The layers are placed on top of each other to form a structure having two dimensions at right angles to each other and a third dimension perpendicular to them and defining a plane having a direction along the two dimensions. A plurality of openings extends through the layers. Each opening is defined by portions of the continuous yarns extending substantially in the direction of the plane and existing in the regular textile planar layers to make the planar layers regular in structure prior to placing them on top of each other. A plurality of passages extends entirely through the structure in a direction substantially perpendicular to the plane of the structure. The continuous yarns comprise both reinforcing fibers which form a reinforcing structure and a matrix material which forms a matrix which binds the layers together and also binds the portions of continuous yarns defining the openings together, thereby forming the passages and stiffening the structure.

摘要： Porous bioabsorbable, bioactive and load-bearing composite medical device structure includes a plurality of regular textile planar layers (1a, 1b . . . ) formed of continuous bioabsorbable polymer matrix and bioceramic fibers acting as reinforcements, both included in continuous fibrous elements (3) forming the textile layers. The layers are placed on top of each other to form a structure having two dimensions (x, y) at right angles to each other according to the two dimensions of the textile layer and a third dimension (z) perpendicular to them and resulting from the piling of the layers. A plurality of passages extend through the layers as a result of the openings (2) defined by portions of the continuous fibrous elements (3) extending substantially in the direction of the plane. The continuous fibrous elements (3) comprise both bioactive ceramic reinforcing fibers which form a reinforcing structure and a bioabsorbable polymer matrix material which forms a matrix which binds the layers together and also binds the portions of continuous fibers defining the openings together, thereby forming the passages and stiffening the structure. This bioactive and bioabsorbable composite structure is suitable to be used as a basic structure in medical devices, especially in osteochondral applications where the load-bearing properties of implant are required.
