There is provided a device for the delivery of surgical fasteners. The device improves the penetration of the fasteners and reduces the effort required for a surgeon to hold opposing pressure in order to deploy the fastener. The device comprises a lever in mechanical cooperation with a resilient element for storing energy; a drive mechanism which cooperates with at least one surgical fastener; and a release mechanism for rapidly releasing stored energy from the resilient element to the drive mechanism. In certain embodiments, at least partial depression of the lever stores energy in the resilient element while release of the lever from the at least partial depressed position does not release the stored energy from the resilient element. Additionally, the drive mechanism converts stored energy from the resilient element upon activation of the release mechanism to deliver the at least one surgical fastener.

1. A device for the delivery of surgical fasteners comprising: a lever arranged to pivot on a fulcrum, a first wheel, a second wheel, a one-way clutch mechanism, a resilient element, and a drive mechanism,wherein said lever is selectively mechanically coupled to said first wheel,wherein said first wheel is mechanically coupled to a resilient element configured to store energy, wherein said resilient element is also operatively coupled to said second wheel and configured to release said stored energy as rotation of said second wheel,wherein the rotation of said second wheel is transmitted via said drive mechanism, said drive mechanism configured to deliver at least one surgical fastener into a target site,wherein, the at least partial depression of said lever stores energy in said resilient element, and said one-way clutch mechanism prevents the release of the stored energy from the resilient element upon release of said lever from the at least partially depressed position. 2. The device of claim 1, wherein said drive mechanism is further configured to deliver the at least one surgical fastener into the target site by imparting of rotational and axial energy to the at least one fastener. 3. The device of claim 1, wherein one complete depression of said lever stores sufficient energy to deploy one surgical fastener into tissue. 4. The device of claim 1, further comprising a trigger for releasing the stored energy. 5. The device of claim 4, wherein one complete depression of the lever stores sufficient energy to deploy more than one surgical fastener. 6. The device of claim 1, wherein release of the stored energy is triggered upon complete depression of said lever. 7. The device of claim 1, wherein upon complete depression of the lever, the release mechanism is triggered before further energy is stored. 8. The device of claim 1, further comprising a handle having an elongate tubular member, for containing a plurality of surgical fasteners, extending distally from the handle. 9. The device of claim 8, wherein the surgical fasteners are iteratively deployable. 10. A method for applying surgical fasteners comprising: positioning a surgical mesh;positioning a surgical fastener delivery system comprising: a lever arranged to pivot on a fulcrum, a first wheel, a second wheel, a one-way clutch mechanism, a resilient element, a drive mechanism, and a handle having an elongate tubular member, wherein said lever is selectively mechanically coupled to said first wheel, wherein said first wheel is mechanically coupled to a resilient element configured to store energy, wherein said resilient element is also operatively coupled to said second wheel and configured to release said stored energy as rotation of said second wheel, wherein the rotation of said second wheel is transmitted via said drive mechanism, said drive mechanism configured to deliver at least one surgical fastener into a target site, wherein, the at least partial depression of said lever stores energy in said resilient element, and said one-way clutch mechanism prevents the release of the stored energy from the resilient element upon release of said lever from the at least partially depressed position; andan elongate tubular member, containing a plurality of surgical fasteners, extending distally from the handle, and having a distal tip;wherein the positioning step includes positioning a distal tip of the elongate tubular member against the surgical mesh; andapplying at least one fastener to secure the mesh to a tissue by:depressing said lever in relation to the handle;triggering instantaneous release of said stored energy;converting released energy into a rotational force to cause rotation of one of the plurality of surgical fasteners, whereby said one of the plurality of surgical fasteners penetrates and secures said mesh to a tissue. 11. The method of claim 10, wherein one complete depression of the lever stores sufficient energy to deploy one surgical fastener into said tissue. 12. The method of claim 10, wherein release of the stored energy is triggered upon complete depression of said lever. 13. The method of claim 10, wherein upon complete depression of the lever, the release mechanism is triggered before further energy is stored. 14. A kit comprising: a device for the delivery of surgical fasteners comprising: a lever arranged to pivot on a fulcrum, a first wheel, a second wheel, a one-way clutch mechanism, a resilient element, a drive mechanism,wherein said lever is selectively mechanically coupled to said first wheel,wherein said first wheel is mechanically coupled to a resilient element configured to store energy, wherein said resilient element is also operatively coupled to said second wheel and configured to release said stored energy as rotation of said second wheel,wherein the rotation of said second wheel is transmitted via said drive mechanism, said drive mechanism configured to deliver at least one surgical fastener into a target site,wherein, the at least partial depression of said lever stores energy in said resilient element, and said one-way clutch mechanism prevents the release of the stored energy from the resilient element upon release of said lever from the at least partially depressed position; andmultiple fastener cartridges. 15. The kit of claim 14, wherein the drive mechanism converts stored energy to rotational energy that drives said at least one surgical fastener into tissue. 16. The kit of claim 14, wherein the drive mechanism converts stored energy to rotational energy that drives said at least one surgical fastener into tissue.
