1. An implantable tissue repair device comprising;
a body comprising a biocompatible hydrogel; and
a plurality of tissue anchoring elements projecting from the body;
wherein the anchoring elements are integrally formed with the body and comprise the same biocompatible hydrogel as the body, and wherein the anchoring elements, in use, are arranged to enter apertures in a tissue and anchor the device to the tissue;
wherein the body of the device comprises at least one discrete layer of fibres on top of the anchoring elements and each anchoring element comprises at least one separate discrete layer of fibres located towards a free distal end thereof,
wherein said at least one separate discrete layer of fibres of the anchoring elements comprises a single layer of longitudinal and lateral fibres extending across the full cross-sectional area of the anchoring elements and the hydrogel of the anchoring elements infiltrates spaces between the fibres of the at least one layer of fibres of the anchoring elements, and
wherein the anchoring elements include at least one thread, stitched through the layer of fibres of the anchoring elements and which extends from the layer of fibres of the anchoring elements substantially parallel with a longitudinal axis of the anchoring elements and is stitched to at least one fibre layer of the body.
