Embodiments of the present invention relate to mechanically-activated microcapsules (MAMCs) for controlled drug-delivery, wherein the MAMCs release one or more active ingredients in response to mechanical stimuli in a subject's body. The MAMCs provide a platform for stimulating biological regeneration, biological repair, modifying disease, and/or controlling disease in mechanically-loaded musculoskeletal tissues.

Mechano-sensitive microcapsules for drug delivery

A cartilage-like biomaterial is bioengineered by using a self-aggregating suspension cell culture with hydrostatic mechanical force without the use of a scaffold or foreign matrix for cell attachment during culture. The cells in suspension culture may be preconditioned prior to application of the hydrostatic mechanical force, such as hydrostatic pressure, for a period of time in the range of about 1 week to about 10 weeks. The cartilage-like biomaterial shares critical structural, phenotype, and functional characteristics with native, intact cartilage tissue.

Methods for the generation of cartilage-like material by mechanical loading

A method and device the may be employed for inhibiting bone growth, including inducing epiphysiodesis or hemiepiphysiodesis, by applying electrical current to a desired region. The device includes a power source and one or a series of electrodes for applying a current sufficient to reduce or stop the growth of a bone to selected regions of the bone. The method and device may be used to correct growth discrepancies in extremities such as the arms or legs, as well as correct the curvature of the spine in scoliosis patients.
