A sling delivery system comprising: a sling assembly, having first and second sling assembly ends (100a, 100b), including an implantable sling, sized and shaped for providing a urethral platform, and first and second guide tubes (106, 108) attached to the sling assembly and having inner and outer ends (106b, 108b; 106d, 108a), wherein the outer end of each of the first and second guide tubes are located at the first and second sling assembly ends, respectively; and a first delivery device including a handle having proximal and distal ends, and a shaft (302, 400, 700) attached at the distal end of the handle and having a length that extends distally from the distal end of the handle inclusive of a conical tip; wherein the shaft includes a first substantially straight section(302a, 400a, 700a) extending along a first axis from the distal end of the handle, a first curved section (302b, 400b, 700b) that curves away from the first axis and a second curved section (302d, 400c, 700d) that curves back toward the first axis, the shaft also including a distal portion that extends between about 1 cm and about 5 cm back across the first axis, wherein the first substantially straight portion, the first curved portion, the second curved portion and the distal portion lie substantially in a single plane; wherein the shaft is shaped for delivering the sling via a trans-vaginal, prepubic approach, the inner end of the first guide tube is sized and shaped for slidably interfitting over the distal end of the shaft, and the first guide tube has an outer end that is tapered; and a pusher assembly slidably fitted over the shaft and extending along a portion of a length of the shaft, the inner end of the first guide tube abuts a distal end of the pusher assembly, such that when the pusher assembly is in a first position the conical tip of the first delivery device is exposed, and when the pusher assembly is in an advanced position, the outer end of the first guide tube moves distally past the conical tip of the first delivery device. a sling assembly, having first and second sling assembly ends (100a, 100b), including an implantable sling, sized and shaped for providing a urethral platform, and first and second guide tubes (106, 108) attached to the sling assembly and having inner and outer ends (106b, 108b; 106d, 108a), wherein the outer end of each of the first and second guide tubes are located at the first and second sling assembly ends, respectively; and a first delivery device including a handle having proximal and distal ends, and a shaft (302, 400, 700) attached at the distal end of the handle and having a length that extends distally from the distal end of the handle inclusive of a conical tip; wherein the shaft includes a first substantially straight section(302a, 400a, 700a) extending along a first axis from the distal end of the handle, a first curved section (302b, 400b, 700b) that curves away from the first axis and a second curved section (302d, 400c, 700d) that curves back toward the first axis, the shaft also including a distal portion that extends between about 1 cm and about 5 cm back across the first axis, wherein the first substantially straight portion, the first curved portion, the second curved portion and the distal portion lie substantially in a single plane; wherein the shaft is shaped for delivering the sling via a trans-vaginal, prepubic approach, the inner end of the first guide tube is sized and shaped for slidably interfitting over the distal end of the shaft, and the first guide tube has an outer end that is tapered; and a pusher assembly slidably fitted over the shaft and extending along a portion of a length of the shaft, the inner end of the first guide tube abuts a distal end of the pusher assembly, such that when the pusher assembly is in a first position the conical tip of the first delivery device is exposed, and when the pusher assembly is in an advanced position, the outer end of the first guide tube moves distally past the conical tip of the first delivery device.
