摘要：
An expander for widening and holding apart an opening of a tissue. The expander may include a body configured to deform from a compacted state into a pre-determined shape in an expanded state in response to a pre-determined physiological condition the body is exposed to. The body with the pre-determined shape in the expanded state may be configured to hold apart the opening of the tissue.
