A tissue closure device includes a main body, a sheath, and a biasing member. The main body has a plurality of resilient arms that each extend from a proximal end to a distal tip. The resilient arms are movable between an open configuration in which the distal tips are radially spaced apart from the longitudinal axis of the main body and from each other and a closed configuration in which the distal tips abut one another at or near the longitudinal axis. The sheath is longitudinally slideable on the main body to move the arms between the open and closed configurations. The biasing member causes the sheath to bias the arms toward the closed configuration.
