The invention discloses a delivery device for use in surgery on an organ in a living body. The delivery device is characterized by a proximal and a distal end interconnected by a main longitudinal axis, the distal end comprising: (a) at least one anchoring device, comprising at least one tissue anchor; and (b) at least one pivoting support in communication with the anchoring device. The anchoring device can pivot freely around the pivoting support independent of the orientation of the pivoting support with respect to the organ, such that the anchoring device can be oriented substantially parallel to and conform to the surface of the organ with which the anchoring device comes into contact.
