Abstract
A medicine delivery system () implantable into a human or animal body includes a medicine delivery unit () and a control unit (). A membrane () seals the delivery opening () of a medicine compartment () and is pre-stressed by an amount less than the predetermined elastic deformation and rupture point limits of the membrane (). A release element () associated with compartment () causes the membrane () to be stressed beyond the deformation and rupture point limits in response to a control signal (). Release element () ruptures the membrane () along a predetermined rupture pattern to permit a first membrane portion (), forming a hinged lid, to separate from a second membrane portion () along the predetermined rupture pattern while remaining attached to the second membrane portion at a hinge ().
