Abstract
A temporary expandable tissue support device includes a plurality of helical filaments superimposed on top of one another to form a tubular body. A first end of the tubular body is coupled to an inner shaft, and a second end of the tubular body is coupled to an outer shaft slidably disposed over the inner shaft. Actuation of the inner and outer shafts in a first direction compresses the plurality of filaments thereby radially expanding the tubular body into an expanded configuration adapted to engage and support tissue at a treatment site without obstructing a fluid from flowing past the tubular body. Actuation of the shafts in a second direction opposite the first direction tensions the plurality of filaments thereby radially collapsing the tubular body into a collapsed configuration that is adapted to be delivered to or removed from the treatment site.
