Abstract:
1. A device, comprising: a central tube defining a central axis; a tube chamber attached to an exterior surface of the central tube, the tube chamber defining an axis of rotation away from the central axis and defining a proximal end and a distal end configured for insertion into tissue; and a rod element disposed within the tube chamber and configured to rotate about the axis of rotation, comprising a curved and unattached free end portion that is biased against an internal surface within the device to assume a first radius of curvature; wherein the rod element is configured for deployment from the distal end of the tube chamber while rotating, the curved and unattached free end portion of the rod element being configured to assume a second radius of curvature when deployed outside of the distal end of the tube chamber, the second radius of curvature being smaller than the first radius of curvature; and wherein the curved and unattached end portion of the deployed rod element is configured to delimit a volume and/or to capture a portion of tissue within the volume.
