1. A delivery device for delivering an implant to an anatomical site in a body of a patient, the device comprising:
a handle having a first slot defined therein and a first raised stop extending from a floor of the first slot,
a shaft having a proximal end and a distal end, the distal end of the shaft having a curved section and the proximal end of the shaft being attached to the handle and having a substantially straight section,
a pusher tube slideably fitted over the shaft and extending from the handle distally along the substantially straight section of the proximal end of the shaft, and
a pushing mechanism having a first tongue that slideably interfits with the first slot of the handle, the pushing mechanism being configured to, as a result of proximally moving the handle with respect to the pushing mechanism, actuate the pusher tube distally along the substantially straight section of the proximal end of the shaft to push the implant into the anatomical site, the first raised stop being configured to contact a projection disposed on the first tongue to help limit proximal movement of the handle,
wherein the pusher tube is adapted to form an operative connection with the implant along the substantially straight section of the proximal end of the shaft.
2. The delivery device of claim 1 , wherein the pusher tube and the pushing mechanism are integrated into a single assembly.
3. The delivery device of claim 1 , wherein the handle includes the first raised stop at a distal end of the first slot and the first tongue includes the projection at a proximal end.
4. The delivery device of claim 1 , wherein the handle includes a second slot substantially parallel to the first slot, and the pushing mechanism includes a second tongue for slideably interfitting with the second slot.
5. The delivery device of claim 4 , wherein the handle includes a second raised stop located at a distal end of the second slot and the second tongue includes a projection located at a proximal end for engaging with the second raised stop to help limit axial motion in a distal direction of the second tongue relative to the handle.
6. The delivery device of claim 1 , wherein the pushing mechanism slideably interfits over the shaft and includes a pusher button for actuating the pushing mechanism.
7. The delivery device of claim 6 , wherein the pusher button includes a reduced diameter portion for accommodating a finger of a medical operator.
8. The delivery device of claim 1 , wherein the pusher tube remains proximal to the curved section.
9. The delivery device of claim 1 , wherein the pusher tube has a length and the substantially straight section of the proximal end of the shaft has a length, and the pusher tube length is less than the substantially straight section length.
10. The delivery device of claim 1 , wherein the pusher tube forms a non-overlapping connection interface with the implant.
11. A system for delivering an implant to an anatomical site in a body of a patient, the system comprising:
an implant for being delivered to an anatomical site in the body of a patient, and a delivery device including:
a handle having a first slot defined therein and a first raised stop extending from a floor of the first slot,
a shaft having a proximal end and a distal end, the distal end of the shaft having a curved section and the proximal end of the shaft having a substantially straight section,
a pusher tube slideably fitted over the shaft and extending from the handle distally along the substantially straight section of the proximal end of the shaft, and
a pushing mechanism having a first tongue that slideably interfits with the first slot of the handle, the pushing mechanism being configured to, as a result of relative movement of the handle away from the pushing mechanism, actuate the pusher tube along the substantially straight section of the proximal end of the shaft to push the implant into the anatomical site, the first raised stop being configured to contact a projection disposed on the first tongue to help limit movement of the handle with respect to the pushing mechanism,
wherein the pusher tube is adapted to form an operative connection with the implant along the substantially straight section of the proximal end of the shaft.
12. The system of claim 11 , wherein the pusher tube and the pushing mechanism are integrated into a single assembly.
13. The system of claim 11 , wherein the handle includes the first raised stop at a distal end of the first slot and the first tongue includes the projection at a proximal end.
14. The system of claim 11 , wherein the handle includes a second slot substantially parallel to the first slot, and the pushing mechanism includes a second tongue for slideably interfitting with the second slot.
15. The system of claim 14 , wherein the handle includes a second raised stop located at a distal end of the second slot and the second tongue includes a projection located at a proximal end for engaging with the second raised help limit axial motion in a distal direction of the second tongue relative to the handle.
16. The system of claim 11 , wherein the first tongue includes the projection located at a proximal end for engaging with a proximal end of the first slot to help limit axial motion in a proximal direction of the first tongue relative to the handle.
17. The system of claim 11 , wherein the pushing mechanism slideably interfits over the shaft and includes a pusher button for actuating the pushing mechanism.
18. The system of claim 11 , wherein the implant comprises a sling assembly having first and second ends.
19. The system of claim 18 , wherein the sling assembly includes a first guide tube attached to the first end and a second guide tube attached to the second end, and each of the first and second guide tubes are sized for slideably interfitting over a distal end of the shaft.
20. The system of claim 19 , wherein the first and second guide tubes are sized for interfitting, alternately, and one at a time, over the shaft and abutting a distal end of the pusher tube.
21. The system of claim 19 , wherein the first guide tube has proximal and distal ends and attaches at the proximal end to the first end of the sling assembly and slideably interfits over the shaft, proximal end first.
22. The system of claim 19 , wherein the first guide tube has proximal and distal ends, attaches at the proximal end to the first end of the sling assembly and slideably interfits over the shaft, distal end first.
23. The system of claim 11 , wherein the pusher tube remains proximal to the curved section.
24. The system of claim 11 , wherein the pusher tube has a length and the substantially straight section of the proximal end of the shaft has a length, and the pusher tube length is less than the substantially straight section length.
