The invention relates to an apparatus and method for forming a hole in a wall of a hollow organ. The applicator includes a hole forming element for forming a hole in the wall of the organ, a positioning means (300) for positioning the hole forming element, and a retractor element (500). In addition, the applicator includes a sequencing means (600) for coordinating the relative movement of the retractor element and the hole forming element in a sequential manner to thereby carry out a procedure for forming a hole in the wall of the hollow organ. The sequencing means may further include a safety latch element operatively coupled to the retracting means and the hole forming element. The safety latch of the invention prevents damage to the internal surface of the organ during the formation of the hole.
