Abstract
A remotely operable stent is disclosed which is radially expandable and contractable along the longitudinal length of the stent. Once the stent is positioned within a body lumen requiring radial support, an actuator and expansion/contraction element increase the radial dimension of the stent along the stent's longitudinal length to provide such support. The stent is remotely operable in vivo using a remote activation system such that the radial dimension of the stent can be changed without the need to re-enter the body lumen.
