Abstract: The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

Abstract: This invention relates to an anti-tamper assembly for a circuit board comprising one or more electronic components, the assembly comprising: a container having side walls, a first, closed end and a second, opposing, open end, the container being configured to be mounted on said circuit board at said open end, over at least one of said electrical components, to form, in use, a sealed cavity around said at least one of said electrical components; a source of radioactive particles mounted within said container; an image sensor for capturing image frames within said sealed cavity, in use, wherein said image sensor comprises a detector region defining an array of pixels; and a processor for receiving said captured image frames, monitoring said image frames for changes in the statistical distribution of active pixels and, in the event that statistical distribution of active pixels indicates the presence of a feature in an image frame, generating a tamper alert.
