Abstract
A device for fastening tissue includes (a) a shaft extending longitudinally from a distal end insertable into a body to a proximal end attached to a controller which remains outside of the body, the shaft including a lumen extending therethrough and an opening extending through a wall of a distal portion thereof to open the lumen to an exterior of the shaft; (b) a first roller housed within the lumen adjacent to a first longitudinal edge of the opening such that a rotation of the first roller grasps and draws tissue from the body into the lumen in combination; and (c) a fastening element housed within the lumen adjacent to the opening and movable from a tissue receiving configuration to a tissue gripping configuration.
