  • Publication number: 20250259609
    Abstract: A woodwind adaptor for woodwind musical instruments that enables a reed instrument to sound like an end-blown flute instrument. The woodwind adaptor replaces the standard reed-housing mouthpiece of the reed instrument with a recorder-style adaptor having a tone hole, whereby the tonal qualities through the reed instrument are, in part, propagated by the player's urged air stream over the edge of the tonal hole.

  • Publication number: 20220047644
    Abstract: The present invention concerns methods and compositions for differentiating cells, including human fibroblasts, into chondrocyte-like cells via in vivo mechanical strain. In particular aspects, fibroblasts are delivered to a joint, such as an intervertebral disc, following which the fibroblasts differentiate into chondrocyte-like cells to treat dysfunction of cartilage therein, including to repair degenerated discs, for example. The fibroblasts that do not differentiate to chondrocytic cells because of the location of the cells, as in the fissures of annulus, or other biomechanical and biochemical micro-environment factors, may produce fibrous matrix molecule(s) in aiding tissue repair and regeneration in both nucleus pulposus and annulus fibrosus. In certain aspects, the fibroblasts prior to delivery to the individual are managed in the absence of growth factors, in vitro mechanical strain, and/or matrix molecules, for example.

  • Patent number: 7648529
    Abstract: A corpectomy device has an inner member telescopingly disposed in an outer member so that the inner member is movable in an axial direction. The inner and outer members are hollow, defining a chamber, and include apertures in communication with the chamber. A locking clip engages the inner and outer members to fix the position of the inner member with respect to the outer member. The longitudinal dimension of the device is adjustable by distracting the inner member so that the inner member extends from the outer member and moving the locking clip from an unlocked position to a locked position.

  • Patent number: 7132098
    Abstract: The invention relates to a method of treatment for a mammal in need of chemonucleolysis. The method comprising the administration of an effective proteoglycan cleaving amount of a proteoglycan-degrading enzyme and an effective amount of a growth factor effective in promoting the synthesis of a matrix component. The proteoglycan-degrading enzyme is preferably chondroitinase. The growth factor is preferably osteogenic protein. The proteoglycan-degrading enzyme and the growth factor are preferably administered simultaneously.

  • Publication number: 20060160214
    Abstract: Surgically implantable tissue engineered intervertebral disc tissues that effectively replicate the physicochemical properties of the corresponding in vivo tissues are provided. Methods for producing such tissues can involve culturing the intervertebral disc cells to produce cells surrounded by an extracellular matrix and culturing the cells and matrix on a semipermeable membrane to form a cohesive tissue.
