The invention is a medical implantable device which is coated by the method according to the invention. The surface of the substrate used for the implantable device, in the raw condition, following a cleaning regime and physiochemical pretreatments, is coated using a biomimetic process in a supersaturated calcium phosphate solution (SCPS) to obtain the desired coating coverage and morphology maintaining a ratio of calcium to phosphorus pH, as well as solution temperature plays a major role in yielding precipitation of the proper phase of CaP so that composition, morphologies, crystal structures, and solubility characteristics are optimal for the deposition process. The biomimetic coating adds the attribute of osteoconductivity to the implant device. To maximize bone growth, the implant must also induce bone growth, or possess the attribute of osteoinductivity. This attribute is acquired by the use of therapeutic agents, i.e. bone morphogenic proteins (BMP), growth factors, stem cells, etc. The preparation of the SCPS solution is slightly altered so that during the immersion of the implant in the SCPS, the therapeutic agents are co-precipitated and bonded with the CaP directly on the underlying surface of the implant device. A final dipping process into a BMP solution provides an initial burst of cellular activity. For delivering stem and / or progenitor cell, after drying the dipped solution of BMP, the cells are cultured on the surface of the implant.

A broad class of photosensitive compounds having enhanced in vivo target tissue selectivity and versatility in photodynamic therapy. Many furocoumarin compounds, such as psoralens, exhibit cytostatic activity when photoactivated but exhibit little in vivo specificity for selectively accumulating in any particular target tissue such as atheromatous plaques. Reactive Oxygen Producing Photosensitizers ("ROPPs") are photoactivatable compounds having an affinity for hyperproliferating cells (such as atheromatous plaque cells), which when photoactivated, produce cytotoxic reaction products. The photoactivity of a ROPP, such as a porphyrin, may be reduced by metalating the porphyrin while the selective affinity of the metalized ROPP for hyperproliferating tissue remains substantially unchanged. By linking a furocoumarin compound to a ROPP to form a F-ROPP, the cytostatic properties of the furocoumarin portion of the F-ROPP can be exploited while the selective affinity of the ROPP portion of the compound for hyperproliferating cells such as atheromatous plaque provides enhanced tissue selectivity without cytotoxicity. In vivo, certain F-ROPPs may be forced to selectively accumulate in a target tissue by illuminating only the target tissue with light having a wavelength operable for photoactivating the F portion of the F-ROPP thereby causing the F-ROPP to either form a monoadduct with or crosslink the cellular DNA in the target tissue. Light of a second wavelength can then be delivered to the target tissue to photoactivate the ROPP portion causing further interference with cellular activity.
