Abstract: Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

Abstract: The present invention comprises an implant for placing inside the eye such that the implant comes into contact with the interior tissue of the eye such that it conforms to the inner globe geometry of the eye. Implants of the present invention may also be used to alter the focal length of the eye thereby providing a treatment method for the correction of myopia and hyperopia. The device may consist of several possible configurations, an open mesh structure, a solid metal ring, a solid polymer shape, a mesh polymer shape or combination of these. The shape may be a curve, a sphere, a ring or a combination thereof that are specifically shaped to approximate a desired portion of the interior globe of the eye in order to treat myopia or hyperopia.

Abstract: Methods for the prevention, or delayed onset or progression of, bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis of a joint are disclosed. The methods involve treating the subchondral bone, while preserving, as much as possible, the joint's articular and cartilage surface. The methods could be performed before, during, or after an initial arthroscopic surgery to repair the joint. Associated devices and instruments for treatment of the subchondral bone are also disclosed.

The body includes multiple first portions that form the first end of the body and a part of the body between the ends. The first portions are separated lengthwise along a substantial portion of a total length of the body. The first portions are biased so that they maintain separation from one another without external interference but are configured to be pushed towards each other. The insert is configured to be placed between the first portions to maintain a separation of the first portions. The body and/or the insert could be formed using one or more magnetic materials.
