A system for anchoring a device in a body lumen or cavity, comprising: a sheath having at least one side opening; a rotatable element disposed within the sheath; and at least one projection extending radially from the rotatable element, wherein rotation of the rotatable element with respect to the sheath pushes a distal end of the projection radially outwardly through the opening and into the body lumen or cavity, the distal end of one of the at least one projection having a suture carrying feature, and wherein the at least one projection is formed from a shape memory material, and wherein the at least one projection springs radially outwardly as it passes outwardly through the side opening as the rotatable element is rotated with respect to the sheath when the at least one projection is exposed to a temperature change.
