Abstract
A site marker is provided that includes a generally hollow body defining a cavity. At least one marker element is captured within the cavity but is able to move within the cavity. The capturing prevents migration of the marker within a body. The site marker is formed into a predeployment configuration whereby the site marker is compressed into a predetermined size and shape to as to be readily positionable within a deployment device. The site marker expands from the predeployment position to a post deployment configuration upon insertion into the body.
