A surgical stapler comprises 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 r
A surgical stapler comprises 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.

1. A tissue closure system, comprising: a plastically deformable tissue closure device comprising: a plurality of legs connected to a base portion, said base portion having a generally U-shaped portion adapted to be supported by a portion of a delivery apparatus, said plurality of legs defining a plane, said U-shaped portion extending from said plurality of legs transverse to said plane, with a single U-shaped portion disposed between adjacent legs of said plurality of legs and having a first portion extending inwardly towards a centerline axis and a second portion extending outwardly from the centerline axis, said U-shaped portion biased toward a U-shape with an open end in a pre-deployed and a deployed state;each said leg being connected to said U-shaped portion, each said leg having a tapered tissue piercing portion on the distal end thereof and having a generally uniform cross-section, transverse to a longitudinal axis of the leg, extending from said base portion toward said tapered tissue piercing portion; anda first member slidable through at least a portion of said tissue closure device in said pre-deployed state, said tissue closure device straddling said first member with a distal end of said first member extending distally from said tissue closure device. 2. The tissue closure system of claim 1, said U-shaped portion connected to each said leg at each upper portion of said U-shape. 3. The tissue closure system of claim 2, wherein said tissue closure device is arranged to translate a force thereon to each said leg. 4. The tissue closure system of claim 3, wherein the force deforms at least a part of said base portion, said base portion being arranged to translate the force thereon to each said leg to move each said leg toward said centerline axis. 5. The tissue closure system of claim 2, wherein said U-shape forms a slot configured to be supported by an elongate member. 6. The tissue closure system of claim 1, wherein said legs, said U-shaped portion and said base portion are formed in a unitary fashion. 7. The tissue closure system of claim 1, wherein said legs, said U-shaped portion and said base portion are symmetrically located about said centerline axis. 8. The tissue closure system of claim 1, wherein said legs, said U-shaped portion and said base portion are formed of a deformable material. 9. A process for closing a wound, comprising: inserting a distal end of a delivery apparatus into tissue surrounding the wound to approach the wound site, the delivery apparatus including a plastically deformable tissue closure device on the distal end of the delivery apparatus, the tissue closure device including a plurality of legs connected to a base portion, the base portion having a generally U-shaped portion adapted to be supported by a portion of the delivery apparatus, the pair of legs defining a plane, said U-shaped portion extending from the plurality of legs transverse to the plane, with a single U-shaped portion disposed between adjacent legs of said plurality of legs and having a first portion extending inwardly towards a centerline axis and a second portion extending outwardly from the centerline axis, each of the legs having a tapered tissue-piercing portion on the distal end thereof and having a generally uniform cross-section, transverse to a longitudinal axis of the leg, extending from the base portion toward the tapered tissue piercing portion, the delivery apparatus including a first member slidable through at least a portion of said tissue closure device, said tissue closure device straddling said first member with a distal end of said first member extending distally from said tissue closure device, said U-shaped portion biased toward a U-shape with an open end in a pre-deployed and a deployed state; anddeforming a portion of the closure device about the wound to pull a portion of the tissue surrounding the wound together. 10. A medical stapling device comprising: a plastically deformable tissue closure device comprising: a body having a longitudinal opening, the opening having a longitudinal axis that extends transverse to an axis of the longitudinal opening passing through a base of the body forming the opening; andat least two opposed longitudinally extending tines spaced about said longitudinal axis, each tine in contact with said body and having a distal end extending distally of the body;the tissue closure device having a closed configuration wherein at least the distal ends of the longitudinally extending tines are disposed adjacent to or contacting each other and wherein the opening is open at the base of the body, and a pre-deployed configuration prior to deformation toward the closed configuration wherein at least the distal ends of the longitudinally extending tines are separated from each other and extend inwardly towards said axis of the body and wherein the opening is open at the base of the body; andwherein the tissue closure device is transformable via deformation of the body at a body deformation portion, the body deformation portion being separate from the opening; anda first member slidable through at least a portion of said tissue closure device, said tissue closure device straddling said first member with a distal end of said first member extending distally from said tissue closure device. 11. The medical stapling device of claim 10, wherein the two or more longitudinally extending tines are transversely opposed to each other. 12. The medical stapling device of claim 10, wherein the two or more longitudinally extending tines are radially opposed to each other. 13. The medical stapling device of claim 10, wherein the longitudinally extending tines are biased by the body. 14. The medical stapling device of claim 10, wherein each of the longitudinally extending tines comprises at least one tissue-engaging prong. 15. The medical stapling device of claim 14, wherein the at least one tissue-engaging prong is capable of at least partially piercing tissue adjacent the wound. 16. The medical stapling device of claim 15, wherein each of the longitudinally extending tines are identical in size and shape and are disposed opposite each other such that the tissue engaging prongs are in at least a mutually adjacent mating relationship when the staple is in the closed configuration. 17. The medical stapling device of claim 10, wherein each of the longitudinally extending tines are mirrored about a plane through the longitudinal opening. 18. A method for closing a wound comprising: positioning a plastically deformable tissue closure device in a pre-deployed configuration in close proximity to the wound, the tissue closure device having a body and an opening having a longitudinal axis that extends transverse to an axis of the longitudinal opening passing through a base of the body forming the opening such that a first member is slidable through at least a portion of the opening of the tissue closure device, the tissue closure device straddling the first member with a distal end of the first member extending distally from the tissue closure device, the body being in contact with at least two longitudinally extending tines, each of the at least two longitudinally extending tines extending inwardly towards the longitudinal axis of the body and the opening being open at the base of the body in the pre-deployed configuration prior to deformation toward a closed configuration, the opening being open at the base of the body in the closed configuration;engaging tissue surrounding the wound with the longitudinally extending tines; andmoving the tines between the pre-deployed and the closed configuration to close the wound. 19. The method of claim 18, wherein moving the longitudinally extending tines between the pre-deployed and the closed configuration to close the wound further comprises deforming the tissue closure device.
