Abstract:
1. An implant, comprising: a) a body; b) at least one recess formed in the body, the recess adapted to retain at least one active pharmaceutical substance; each of the at least one recesses having: an opening providing access to the at least one recess; and a deflectable element having an upper surface portion and a lower surface portion and disposed within the at least one recess such that the at least one pharmaceutical substance is in contact with either or both the upper and lower surfaces of the deflectable element when the level of pharmaceutical substance is at its maximum, the deflectable element being at least partially either ferromagnetic or permanently magnetic, the deflectable element being displaceable by vibration in response to an excitation signal from a resting first state which does not allow the at least one pharmaceutical substance to move from the at least one recess through the opening, to a vibrating second state, the vibrating second state causing agitation of the at least one active pharmaceutical substance from the at least one recess through the opening or movement of the at least one active pharmaceutical substance from the at least one recess through the opening, wherein in response to the removal of the excitation signal the deflectable element returns to the resting first state which can thereafter again be excited into the vibrating second state.
