Abstract
A multi-stage stent including a stent body and a bio-erodible material is provided. The stent body can be compressed in an initial state and the bio-erodible material can be coupled to the stent body in a configuration that holds the stent body in an expanded first state, following a first stage expansion from the initial state upon deployment of the stent body. Upon erosion of the bio-erodible material the stent body is released from the first state to expand further in a second stage expansion to a second state.
