Abstract: A cryopreserved cartilage product is disclosed. The cryopreserved cartilage product can include a partially digested cryopreserved natural cartilage collagen matrix isolated from a subject. The collagen matrix can include viable cells embedded within the collagen matrix that are native to the collagen matrix and that were embedded in the collagen matrix when the collagen matrix was isolated from the subject, at least 70% of the embedded cells native to the collagen matrix can be viable in the cryopreserved cartilage product, and the partially digested collagen matrix can retain interaction between the collagen matrix and the native cells.

Abstract: This invention provides disrupted cartilage products, methods of manufacturing disrupted cartilage products, and methods of treating a subject comprising administering a cartilage product. The cartilage products are manufactured by a method comprising disrupting a collagen matrix, e.g. to produce a flexible cartilage product. Optionally, the cartilage products comprise viable chondrocytes, bioactive factors such as chondrogenic factors, and a collagen type II matrix. Optionally, the cartilage products are non-immunogenic.

Abstract: Disclosed are osteochondral constructs that can be utilized to encourage both bone and articular cartilage tissue repair in synovial joints. Disclosed constructs are composites including a hydrogel portion for implant in a cartilage defect site and an adjacent portion for implant in a bone defect site. The portion to be implanted in a bone defect site can include a polymeric/ceramic composite material. Disclosed constructs also include a polymeric anchor that can secure the construct at the desired site. Disclosed constructs can also include capillary channeled fibers within the bone portion of the construct that can provide improved nutrient flow to and waste flow from cells growing and developing on and in the construct.

Abstract: An acceleration and scan expansion lens system for use in an electron discharge tube provides scan expanion in which the amount of scan expansion provided in the horizontal direction is independent of the amount of scan expansion provided in the vertical direction. In a preferred embodiment, the lens system (10) is employed in a cathode-ray tube (12) which has greater deflection sensitivity in the vertical direction than in the horizontal direction. The lens system includes a mesh electrode structure (62) that has a dome-shaped mesh element (66) which is supported by an electrically connected to a metallic cylindrical support element (70). The dome-shaped mesh element is formed to have a concave surface as viewed in the propagation direction (35) of the electron beam and is of rotationally symmetric shape. The lens system also includes an annular electrode element (64) that has an aperture of elliptical shape and is positioned adjacent the output end of the mesh electrode structure.
