Abstract
A stent for disposition in a body passageway or duct to maintain the duct walls apart, for example, to allow the flow of fluid therethrough, includes an elongate flexible support wire formed into an annular lattice having a central void, for disposition at a target location in the duct. Also included is an elongate flexible connecting wire joined at a distal end to the annular lattice and having a discontinuity for severing when supplied with a perturbation signal, a balloon catheter having an expandable section disposable in the void of the annular lattice so that when the expandable section is expanded, it forces the annular lattice radially outwardly to contact and hold apart the duct walls, and a fluid supply for supplying fluid to the expandable section of the balloon catheter to cause it to expand. A perturbation signal source is provided for supplying the perturbation signal to the discontinuity of the connecting wire to cause severance thereof.
