Claim:
A method of anchoring a device in a body lumen or cavity, comprising: inserting a device into a body lumen or cavity, the device comprising: a sheath having at least one sidewall opening and a longitudinal axis; a rotatable element disposed within the sheath and rotatable about the longitudinal axis; and at least one projection extending radially from the rotatable element, the at least one projection having an upper surface disposed and movable within a plane transverse to the longitudinal axis; rotating the rotatable element with respect to the sheath to move a distal end of the at least one projection outwardly within the plane, through the at least one sidewall opening, and into the body lumen or cavity; wherein moving the rotatable element relative to the sheath comprises rotating the sheath and rotatable element in the same direction at different speeds; and capturing an end of a suture disposed in a suture-carrying feature on the at least one projection by advancing a needle through the body tissue and into the suture-carrying feature within the body lumen.
