The present embodiments provide systems and methods for deploying at least one clip during a medical procedure. In one embodiment, the system comprises a clip having first and second arms. A locking pin is coupled to the clip and disposed for incremental movement relative to the clip. Further, a tether is coupled to the locking pin, wherein a first tether segment is secured to a distal region of the second arm, and a second tether segment is secured to a distal region of the first arm. In use, proximal retraction of the locking pin causes a proximal retraction of the first and second tether segments to move the clip between open and closed states. Incremental retraction of the locking pin incrementally advances the clip between the open and closed states.

1. A system for deploying at least one clip during a medical procedure, the system comprising: a clip having first and second arms, wherein distal regions of the first and second arms tend to be spaced apart from each other when the clip is in an open state, and wherein the distal regions of the first and second arms are adjacent to each other when the clip is in a closed state;a locking pin having a proximal end, a distal end, and a main body extending therebetween, wherein the locking pin is coupled to the clip and disposed for incremental movement relative to the clip; anda tether coupled to the locking pin, wherein a first tether segment is secured to the distal region of the second arm, and a second tether segment is secured to the distal region of the first arm, wherein the first and second tether segments cross over each other,wherein proximal retraction of the locking pin causes a proximal refraction of the first and second tether segments to move the clip between the open and closed states. 2. The system of claim 1 wherein the tether is coupled to the locking pin through a bore formed in the locking pin. 3. The system of claim 1 further comprising a retainer releasably coupled to the locking pin, wherein proximal retraction of the retainer causes proximal retraction of the locking pin. 4. The system of claim 3 wherein the retainer comprises a suture that is looped through a bore formed in the locking pin. 5. The system of claim 1 further comprising: a first securing member disposed on the distal region of the first arm for securing the second tether segment to the distal region of the first arm; anda second securing member disposed on the distal region of the second arm for securing the first tether segment to the distal region of the second arm. 6. The system of claim 5 wherein the first and second securing members comprise bores formed in the distal regions of the first and second arms, respectively. 7. The system of claim 1 wherein the clip further comprises a base region having a bore formed longitudinally therethrough, wherein at least a portion of the locking pin is disposed through the bore in the base region. 8. The system of claim 7 wherein the locking pin comprises at least one region having a first diameter, and further comprises at least one flared region having a second diameter, wherein the second diameter is greater than the first diameter, wherein the second diameter of the flared region is greater than a diameter of the bore of the base region such a sufficient retraction force must be imposed upon the locking pin to incrementally proximally retract the locking pin through the base region of the clip. 9. The system of claim 1 wherein the first tether segment is disposed around an external surface of the locking pin at a location proximal to attachment of the first tether segment to the distal region of the second arm. 10. The system of claim 1 wherein the first tether segment is guided through a bore formed in the first arm at a location proximal to attachment of the first tether segment to the distal region of the second arm, and the second tether segment is guided through a bore formed in the second arm at a location proximal to attachment of the second tether segment to the distal region of the first arm. 11. A system for deploying at least one clip during a medical procedure, the system comprising: a clip having first and second arms, wherein distal regions of the first and second arms tend to be spaced apart from each other when the clip is in an open state, and wherein the distal regions of the first and second arms are adjacent to each other when the clip is in a closed state;a locking pin having a proximal end, a distal end, and a main body extending therebetween, wherein the locking pin is coupled to the clip and disposed for incremental movement relative to the clip;a tether coupled to the locking pin, wherein a first tether segment is secured to the distal region of the second arm, and a second tether segment is secured to the distal region of the first arm,wherein proximal retraction of the locking pin causes a proximal refraction of the first and second tether segments to move the clip between the open and closed states; anda retainer releasably coupled to the locking pin, wherein proximal retraction of the retainer causes proximal retraction of the locking pin,wherein the retainer comprises a suture that is looped through a bore formed in the locking pin. 12. A system for deploying at least one clip during a medical procedure, the system comprising: a clip having first and second arms, wherein distal regions of the first and second arms tend to be spaced apart from each other when the clip is in an open state, and wherein the distal regions of the first and second arms are adjacent to each other when the clip is in a closed state;a locking pin having a proximal end, a distal end, and a main body extending therebetween, wherein the locking pin is coupled to the clip and disposed for incremental movement relative to the clip; anda tether coupled to the locking pin, wherein a first tether segment is secured to the distal region of the second arm, and a second tether segment is secured to the distal region of the first arm,wherein proximal retraction of the locking pin causes a proximal refraction of the first and second tether segments to move the clip between the open and closed states, andwherein the first tether segment is guided through a bore formed in the first arm at a location proximal to attachment of the first tether segment to the distal region of the second arm, and the second tether segment is guided through a bore formed in the second arm at a location proximal to attachment of the second tether segment to the distal region of the first arm.
