Benefits of technology
The patent describes a device that can be used to anchor to tissue. The device has multiple anchoring elements that form a cruciform shape on the back surface of the body. These elements can be arranged in different ways, such as a ring or fringe around the outer edge of the body. The device can be frozen to maintain its shape before being used to anchor to tissue. The technical effect is that the device can effectively anchor to tissue with the help of the anchoring elements.
Problems solved by technology
Osteoarthrosis is caused by the progressive damage and breakdown of articular cartilage most commonly in the hip and knee and is an important cause of pain and reduced mobility in young and old people alike.
Injury to the fibrocartilage of the meniscus is a common sports injury and is also seen as a result of road traffic accidents and other traumatic injuries.
No wholly satisfactory procedure exists for replacing damaged articular cartilage in osteoarthrosis and instead in the case of the two most frequently injured joints, the hip and knee, artificial prostheses are most commonly used to replace the entire joint.
While these increase mobility and reduce pain they suffer from progressive wear, mechanical failure, adverse tissue reactions and loosening at their interphase with the bone.
Whilst implantable cartilaginous tissue repair devices of the prior art are all useful in the repair, augmentation or replacement of damaged cartilage, many such devices suffer from a number of problems, such as: a) failure to anchor securely to existing bone or cartilage; b) failure to integrate with existing bone or cartilage; c) failure of the devices after implantation due to wrinkling, warping, shrinking, cracking or other structural deterioration or failure of the devices over time, or through loosening or complete seperation of the device from its anchor; and d) failure of the device to maintain its overall shape under load within or on the repaired tissue.

Description
TECHNICAL FIELD OF THE INVENTION[0001]This invention relates to implantable tissue repair devices and methods for manufacturing implantable tissue repair devices. In particular, but not exclusively the invention relates to implantable tissue repair devices with improved means to anchor or secure the devices to, or adjacent to, a tissue in need to repair, such as bone or cartilage.BACKGROUND TO THE INVENTION[0002]Cartilage in the adult mammalian body occurs in three principal forms: hyaline cartilage; white fibrocartilage; and yellow elastic cartilage. Hyaline cartilage is chiefly present as articular cartilage in the synovial diarthroidal joints e.g. the knee, hip and shoulder, and between long bones, where it forms the stiff and smooth articulating surfaces. White fibrocartilage is present in the menisci of the knee and temporomandibular joint of the jaw and in intervertebral discs. Yellow elastic cartilage gives support to the epiglottis, Eustachian tube and external ear.[0003]Thr...
