A surgical stapler having a hollow shaft 10 and a tube 92 slidable axially within the shaft between a forward position wherein one end 96 of the tube projects beyond a free end of the shaft to enter a puncture site in a blood vessel and a rearward position wherein the end of the locator tube is retr
A surgical stapler having a hollow shaft 10 and a tube 92 slidable axially within the shaft between a forward position wherein one end 96 of the tube projects beyond a free end of the shaft to enter a puncture site in a blood vessel and a rearward position wherein the end of the locator tube is retracted within the shaft. A surgical staple 40 straddles the tube 92 and is slidable thereon forwardly towards an anvil 24 against which the staple may be deformed to staple together the opposite edges of the puncture site. A cam mechanism drives the staple forwardly along the tube 92 into deforming engagement with the anvil and at the same time retracts the tube into the shaft in time to allow the legs of the staple to close onto the puncture site.

The surgical stapler of claim 1, wherein the trigger is coupled to a housing formed on a proximal end of the shaft. 4. A surgical instrument for closing a puncture in a liquid-carrying vessel, comprising: a shaft;a locator received within the shaft and having a lumen configured to receive a guidewire, the lumen including a fluid outlet port and a guidewire exit port and including a distal opening forming both a distal fluid inlet port and a distal guidewire entry port, the distal fluid inlet port and the distal guidewire entry port being substantially coterminous with a distal end of the locator, the fluid outlet port and guidewire exit port being in fluid communication with the lumen and longitudinally separated one from another and the fluid outlet port being distal the guidewire exit port, the locator being slidably movable with respect to the shaft between a forward position in which the locator projects beyond a free end of the shaft to enter a puncture site in a liquid-carrying vessel, and a rearward position in which the locator is retracted relative to the shaft; anda trigger configured to drive a closure device toward the puncture site and to substantially simultaneously retract the locator such that the locator is withdrawn from the closure device to allow the closure device to close the puncture. 5. The surgical instrument of claim 4, further comprising a housing, the shaft extending distally from the housing and the trigger being located on the housing, the lumen extending from a proximal end of the housing to a distal end of the locator. 6. The surgical instrument of claim 4, the closure device disposed around the locator and having at least two tissue-penetrating legs formed thereon. 7. The surgical instrument of claim 6, wherein the at least two tissue-penetrating legs of the closure device are movable between a first, pre-deployed position, wherein the legs are substantially parallel to one another, and a second, deployed position wherein the legs extend toward one another. 8. The surgical instrument of claim 6, wherein the closure device is a staple. 9. A surgical instrument for closing a puncture in a liquid-carrying vessel, comprising: a shaft having a locator slidably disposed therein, the locator having a lumen configured to receive a guidewire and being adapted to extend forward of the shaft to be positioned through a puncture in a liquid-carrying vessel, the lumen including a fluid outlet port and a guidewire exit port and including a distal opening forming both a distal fluid inlet port and a distal guidewire entry port, the distal fluid inlet port and the distal guidewire entry port being in fluid communication by an open neck portion disposed between the distal fluid inlet port and the distal guidewire entry port, the fluid outlet port and guidewire exit port being in fluid communication with the lumen, the shaft having a reduced-cross section region configured to allow the guidewire to exit the guidewire exit port and prevent passage of liquid through the guidewire exit port; anda trigger configured to simultaneously retract the locator from the puncture in the liquid-carrying vessel while effecting delivery of a closure device to close the puncture. 10. The surgical instrument of claim 9, wherein the trigger is located on a housing coupled to a proximal end of the shaft. 11. The surgical instrument of claim 9, the closure device disposed around the locator and having at least two tissue-penetrating legs formed thereon. 12. The surgical instrument of claim 11, wherein the at least two tissue-penetrating legs of the closure device are movable between a first, pre-deployed position, wherein the legs are substantially parallel to one another, and a second, deployed position wherein the legs extend toward one another. 13. The surgical instrument of claim 11, wherein the closure device is a staple. 14. A surgical instrument for closing a puncture wound, comprising: a housing having an elongate shaft extending distally therefrom;a member having a lumen configured to receive a guidewire, the lumen extending from a proximal end of the housing to a distal end of the member, the lumen including a fluid outlet port and a guidewire exit port and including a distal opening forming both a distal fluid inlet port and a distal guidewire entry port, the distal guidewire entry port of the opening having a diameter greater than a width of the distal fluid inlet port, the fluid outlet port and guidewire exit port being in fluid communication with the lumen, the member having a reduced-cross section region toward the guidewire exit port that is configured to allow the guidewire to exit the guidewire exit port and prevent passage of liquid through the guidewire exit port, the member extending from the housing and slidably movable with respect to the shaft between a forward position in which the member projects beyond a free end of the shaft to enter a puncture site in a liquid-carrying vessel and thereby locate the free end of the shaft at the puncture site, and a rearward position in which the member is retracted relative to the shaft; anda trigger located on the housing and effective to cause a closure device to advance through the elongate shaft and to cause the member to be substantially simultaneously retracted relative to the shaft such that the member is withdrawn from the closure device in time to allow the closure device to close the puncture site. 15.
