Implantable devices for musculoskeletal repair and regeneration

Abstract

This application describes an implantable device for tissue repair comprising at least two fabrics with interconnecting spacer elements transversing, connecting, and separating the fabrics, forming the device. Some embodiments have fixation points which can be an extension of at least one of the fabrics. The implantable device allows modification of the two fabrics having varying constructions, chemistries, and physical properties. The spacer elements create a space between the two fabrics, which can be used for the loading of biological materials (peptides, proteins, cells, tissues), offer compression resistance (i.e. stiffness), and compression recovery (i.e., return to original dimensions) following deformation and removal of deforming load. The inclusive fixation points of the fabrics are designed to allow for fine adjustment of the sizing and tension of the device to promote integration with the surrounding tissues as well as maximize the compressive resistance. The fixation points can include either the first fabric, the second fabric, or the combination of both fabrics. This device is suitable for soft and hard tissue regeneration or replacement with a preference for musculoskeletal tissues including but not limited to cartilage (including hyaline (referred to as articular; e.g. cartilage on the ends of long bones), fibrous (e.g. meniscus or intervertebral discs), elastic (e.g. ear, epiglottis)), bone, muscle, tendon, ligament, and fat.
