1. A method of ligating a fluid carrying structure, the method comprising the steps of:
- inserting into a patient a surgical ligation instrument having upper and lower clamping surfaces moveable relative to one another between an open position for receiving the fluid carrying structure and a closed position for compressing the fluid carrying structure therebetween, the upper and lower clamping surfaces being adapted to contact the fluid carrying structure;
positioning the fluid carrying structure between the clamping surfaces of the instrument;
moving a ligation clip over a portion of the clamping surfaces of the instrument overlying a portion of the fluid carrying structure while the clamping surfaces are in the open position, the ligation clip being resiliently biased to a closed position;
moving the upper and lower clamping surfaces to the closed position while the ligation clip is over the clamping surfaces; and
releasing the ligation clip to permit the ligation clip to move to the closed position of the ligation clip.

9. A surgical ligation apparatus for compressing a fluid carrying structure, comprising:
-
a proximal end, an opposite distal end for insertion first into a patient, and a mid-longitudinal axis passing through said proximal and distal ends, said distal end having no portion adapted to move away from the mid-longitudinal axis; and
a shaft having a passage adapted to receive at least one surgical ligation clip therein, the clip being biased to a closed position, said shaft having a guide surface adapted to move the clip to an open position. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A surgical ligation apparatus for compressing a fluid carrying structure, comprising:
-
a proximal end, an opposite distal end adapted to be inserted first into a patient, and a mid-longitudinal axis passing through said proximal and distal ends; and
a shaft having a passage adapted to receive at least one surgical ligation clip therein, the ligation clip having a length and being biased to a closed position, said shaft having a guide surface proximate said distal end adapted to move the ligation clip to an open position, said guide surface being adapted to retain the ligation clip in the open position while a majority of the length of the ligation clip is beyond said distal end of said apparatus. - View Dependent Claims (17, 18, 19, 20, 21, 22)
