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 for positioning the hole forming element, and a retractor element. In addition, the applicator includes a sequencing means 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 keeps prevents damage to the internal surface of the organ during the formation of the hole.

1. An applicator for forming a hole in a wall of a hollow organ comprising: a hole forming element for forming a hole in the wall of the organ, the hole forming element having a cutting element on a distal end thereof;a positioning element coupled to the hole forming element for positioning the hole forming element;retractor element operatively coupled to the positioning element; anda sequencing element 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;wherein the retractor element comprises a retractor body movably disposed within the hole forming element and an expansion element disposed on a distal end of the retractor body, the expansion element being expandable;wherein the expansion element is expandable from an unexpanded state to fully expanded state and to a partially expanded state;wherein the sequencing element controls the expansion of the expansion element from the unexpanded state, to the fully expanded state, and to the partially expanded state in a sequential manner;wherein the sequencing element further comprises a safety latch element operatively coupled to the retracting element and the hole forming element; andwherein the sequencing element further comprises a sequencing bolt that extends through a cylinder cam slot formed in the retractor element, a pusher cam slot formed in a pusher element, and a safety latch cam slot formed in the safety latch element. 2. The applicator of claim 1, wherein the sequencing element comprises a mechanism for causing the elements to assume the following states in seriatim: a) a first state in which the sequencing bolt moves from a first position to a second position in each of the cylinder cam slot, the pusher cam slot, and the safety latch cam slot, thereby expanding the expansion element to a fully expanded state while retaining the retractor element in a fully extended position relative to the hole forming element;b) a second state in which the sequencing bolt moves from the second position to a third position in the cylinder cam slot, the pusher cam slot, and the safety latch cam slot, thereby retaining the expansion element in the fully expanded state and the retractor element in the fully extended position;c) a third state in which the sequencing bolt moves from the third position to a fourth position in the cylinder cam slot, the pusher cam slot, and the safety latch cam slot, thereby permitting the retractor element to move towards the hole forming element while retaining the expansion element in the fully expanded state;d) a fourth state in which the sequencing bolt is locked in a fourth position in the safety latch cam slot, the cylinder cam slot, and the pusher cam slot, thereby retaining the expansion element in the fully expanded state;e) a fifth state in which the safety latch element is moved relative to the retractor element such that the sequencing bolt is repositioned from the fourth position to a fifth position in the safety latch cam slot while remaining in the fourth position in the cylinder cam slot and the pusher cam slot, thereby releasing the expansion element from the fully expanded state; andf) a sixth state in which the sequencing bolt moves from the fifth position to a sixth position in the safety latch cam slot, and simultaneously, from the fourth position to a fifth position in the cylinder cam slot and the pusher cam slot, to allow the expansion element to assume the partially expanded state. 3. The applicator of claim 1, wherein the organ is a heart. 4. The applicator of claim 1, further comprising a connector conduit coupled to the hole forming element. 5. The applicator of claim 1, wherein the expansion element is a balloon. 6. The applicator of claim 1, wherein the expansion element is an expandable sponge. 7. The applicator of claim 1, wherein the expansion element is an umbrella mechanism. 8. The applicator of claim 1, wherein the sequencing element comprises a cam mechanism. 9. The applicator of claim 1, wherein the sequencing element comprises a gear mechanism. 10. The applicator of claim 1, wherein the sequencing element comprises at least one servo mechanism operatively coupled to the positioning element and a controller operatively coupled to the at least one servo mechanism. 11. The applicator of claim 10, further comprising a button operatively coupled to the sequencing element for activating the sequencing element upon depression of the button to thereby accomplish steps of a procedure for implanting the connector conduit within the organ wall.
