A medical device comprising a combination of one or more dynamic structural elements (12, 24, 32, 34, 42, 46, 60, 62) and one or more non-dynamic structural elements (11, 14, 26a, 26b, 31, 36, 66) and having a first structural form immediately after deployment in a body, the device adapted to change in vivo to a second structural form due to a change induced in the one or more dynamic structural elements without releasing debris greater than a predetermined size. An exemplary device may comprise at least one biodegradable element contained radially between a first confining member (18a, 43a) and a second confining member (18b, 43b). |
