A material that can be applied as implants designed to artificially replace or augment the cornea, such as an artificial cornea, corneal onlay, or corneal inlay (intrastromal lens) is provided. The artificial corneal implant has a double network hydrogel with a first network interpenetrated with a second network. The first network and the second network are based on biocompatible polymers. At least one of the network polymers is based on a hydrophilic polymer. The artificial cornea or implant has epithelialization promoting biomolecules that are covalently linked to the surface of the double network hydrogel using an azide-active-ester chemical linker. Corneal epithelial cells or cornea-derived cells are adhered to the biomolecules. The double network has a physiologic diffusion coefficient to allow passage of nutrients to the adhered cells.

An implant designed e.g. as a replacement for an articulating surface of a human or animal joint is secured to the bone tissue with the aid of a plurality of fasteners (3). The implant (2) comprises a bone side to be brought into contact with the bone tissue, which bone side is equipped with a plurality of fastening structures restricted to this bone side. The fasteners (3) comprise a distal and a proximal side, wherein the distal side is equipped for being anchored in bone tissue and the proximal side is equipped for being connected with one of the fastening structures of the implant (2). The distal sides of the fasteners (3) are anchored in the bone tissue of the appropriately prepared bone and the implant (2) is then attached to the anchored fasteners (3) by connecting the fastening structures with the proximal sides of the fasteners (3), wherein the implant (2) is pressed against the proximal sides of the anchored fasteners (3).

The disclosure relates to devices and methods for implantation of an orthopedic device between skeletal segments using limited surgical dissection. The implanted devices are used to adjust and maintain the spatial relationship(s) of adjacent bones. Depending on the implant design, the motion between the skeletal segments may be increased, limited, modified, or completely immobilized.

An implant, and a method of designing the implant, takes into account heterogeneous bone properties. The method may be directed to designing a fixation feature of the implant using a virtual bone model. Bone property information derived from image data may be mapped to the virtual bone. A virtual model of the implant may be created, including a virtual fixation feature characterized by an input parameter. One or more simulations may be performed, the simulations being of an implantation of the virtual implant on the virtual bone. Values for at least one input parameter may be used for each simulation, each simulation resulting in a value for an output parameter. The input and output values may be analyzed to derive a relationship between the values, the relationship being used to design the fixation feature of the implant.

The invention herein generally refers to an in situ cartilage repair implant. The implant promotes cartilage repair by providing a sealed barrier that prevents the flow of synovial fluid and inflammatory cytokines into a surgically prepared hole that accommodates the implant. Optionally, additives are associated with the implant to promote cartilage repair.

A bone alignment implant includes a first bone fastener with a first bone engager that is adapted for fixation into the metaphyseal bone and a second bone fastener with a second bone engager that is adapted for fixation into the diaphyseal bone. A link connecting the two fasteners spans across the physis. Alternatively, the bone alignment implant is adapted for fixation into the diaphyseal sections of two adjoining vertebral bodies. These implants act as a flexible tethers between the metaphyseal and the diaphyseal sections of bone during bone growth. These implants are designed to adjust and deform during the bone realignment process. When placed on the convex side of the deformity, the implant allows the bone on the concave side of the deformity to grow. During the growth process the bone is then realigned. A similar procedure is used to correct torsional deformities.

Described is a new bone healing method and class of bone fixation implants that change shape once implanted so as to minimize non-healing and speed the bone healing process. The bone fixation method involves shape changing implants that continuously hold the bones in apposition so that a gap does not form. Gaps in time allow non-bony tissue to infiltrate and stop healing. Furthermore, the implants actively compress bone to increase bone mass and strength. Bone cell pressure due to compression and electrical current flow due to bone deformation act to stimulate healing. The new implant designs also provide a scaffolding to conduct bone through the implant and across the healing bone interface. The methods and designs are applicable to but not limited to use for bone screws, plates, staples, rods, cylinders and external fixation devices.
