Abstract
A suturing apparatus configured to suture an opening extending through an outer wall of the heart, such as a transapical opening, can comprise an elongate body having a proximal end, a distal end, a tapered or rounded tip, one or more arms, and one or more needles. A handle at the proximal end of the elongate body can be configured to be manipulated from outside of the heart. The elongate body can have a substantially constant outer diameter between the handle and the distal end. The arms can hold portions of suture a distance away from the outer diameter of the elongate body. The arms can be extendable from said body from a retracted position to an extended position. The arms in the extended position can point distally and form an acute angle with a longitudinal axis of the elongate body. The plurality of needles can be movable to pass through heart tissue into engagement with the suture portions held by the arms and back through the heart tissue to draw the suture portions through the heart tissue.
