An actuator for an interventional surgical procedure is described. The actuator may include an actuator body having a distal end and a proximal end. A central expandable section is located between the distal end and the proximal end. The expandable section is operable between an unactuated condition in which the expandable section is in a furled state and an actuated condition in which the expandable section is in an unfurled state. A needle is located at the expandable section. The needle is moveable in an approximately perpendicular direction relative to a central longitudinal axis of the actuator body from a position within the actuator body to a position outside of the actuator body.
