The implant delivery system comprises a handle body, handle insert, and a needle. The handle insert extends through the handle body and includes a proximal end configured to engage with the handle body and a distal end configured to engage the needle. The handle insert is rotatable between a first position in which the needle may be inserted or removed and a second position in which the needle is locked in place. ## Claims ### Claim 1 An implant delivery system for delivering a urethral sling implant to a surgical target site within a patient's pelvis during a retropubic midurethral sling procedure, comprising: a handle body comprising a proximal end, a distal end, a bulbous proximal portion including a proximal recess formed at the proximal end, an elongated distal portion extending distally from the bulbous proximal portion along a longitudinal axis and having a distal aperture at the distal end, and an axial lumen extending through the handle body along the longitudinal axis between the proximal recess and the distal aperture, the longitudinal axis defining a longitudinal direction; a handle insert having a proximal knob portion and an elongated extension extending distally from the proximal knob portion, the elongated extension having a distal end including a needle coupling element, the handle insert configured to reversibly couple with the handle body such that the elongated extension is received within the axial lumen and the proximal knob portion is received within the proximal recess; and a surgical needle having a proximal coupling element configured to removably couple with the handle insert, an implant coupling element configured to engage a surgical implant for delivery to a surgical target site, an elongated curvilinear shaft extending distally from the proximal coupling element, and a shaped distal tip configured to penetrate patient anatomy; wherein the elongated curvilinear shaft is curved in the longitudinal direction, and the elongated curvilinear shaft includes an arcuate surface extending along at least a portion of the curvilinear shaft, the arcuate surface having an arc component oriented in the longitudinal direction and a flat component oriented in a direction transverse to the longitudinal direction, and wherein the arcuate surface is dimensioned to contact a pubic symphysis during the retropubic midurethral sling procedure to provide at least one of tactile confirmation of needle orientation, visual confirmation of needle orientation, and improved needle tracking during an advancement of the needle into the patient along the pubic symphysis. ### Claim 2 (depends on 1) The implant delivery system of claim 1, wherein the distal aperture comprises a tapered needle interface. ### Claim 3 (depends on 1) The implant delivery system of claim 1, wherein the elongated curvilinear shaft of the surgical needle has a concave side and a convex side. ### Claim 4 (depends on 3) The implant delivery system of claim 3, wherein the arcuate surface is positioned on the concave side. ### Claim 5 (depends on 4) The implant delivery system of claim 4, wherein the elongated curvilinear shaft has a second arcuate surface on the convex side. ### Claim 6 (depends on 1) The implant delivery system of claim 1, wherein the handle insert is configured to be coupled with the handle body in a first rotational orientation that enables coupling of the proximal coupling element of the surgical needle with the needle coupling element of the handle insert through the distal aperture of the handle body, and thereafter rotated to a second rotational orientation wherein the surgical needle is securely coupled with the handle insert and the handle insert is securely coupled with the handle body. ### Claim 7 (depends on 6) The implant delivery system of claim 6, wherein the handle insert is non-threadedly rotated within the handle body. ### Claim 8 (depends on 6) The implant delivery system of claim 6, wherein the handle insert is rotated 90° in a clockwise direction to transition from the first rotational orientation to the second rotational orientation. ### Claim 9 (depends on 6) The implant delivery system of claim 6, wherein the handle insert is configured to produce at least one of audible and tactile feedback upon completing a transition from the first rotational orientation to the second rotational orientation. ### Claim 10 (depends on 9) The implant delivery system of claim 9, wherein the handle insert includes at least one deflectable member configured to forcibly deflect into a retention recess formed within the proximal recess upon completing a transition from the first rotational orientation to the second rotational orientation. ### Claim 11 (depends on 1) The implant delivery system of claim 1, further comprising a protective sheath covering a substantial portion of the elongated curvilinear shaft of the surgical needle, the surgical needle further comprising an unsheathed distal portion positioned between a distal end of the protective sheath and the shaped distal tip. ### Claim 12 (depends on 11) The implant delivery system of claim 11, wherein the unsheathed portion comprises a visual depth indicator. ### Claim 13 (depends on 12) The implant delivery system of claim 12, wherein the unsheathed portion has a length dimension within a range of 15 mm to 50 mm. ### Claim 14 (depends on 11) The implant delivery system of claim 11, wherein the sheath has a color that provides contrast with patient anatomy under cytoscopy. ### Claim 15 (depends on 14) The implant delivery system of claim 14, wherein the sheath is black. ### Claim 16 (depends on 11) The implant delivery system of claim 11, wherein the sheath is a non-removable overwrap applied to the needle. ### Claim 17 An implant delivery system for delivering a urethral sling implant to a surgical target site within a patient's pelvis during a retropubic midurethral sling procedure, comprising: a handle member having an elongated shaft including a coupling element configured to removably couple with a surgical needle, and a longitudinal axis extending through the elongated shaft, the longitudinal axis defining a longitudinal direction; a surgical needle having a proximal coupling element configured to removably couple with the handle member, an implant coupling element configured to engage a surgical implant for delivery to a surgical target site, an elongated curvilinear shaft extending distally from the proximal coupling element, and a shaped distal tip configured to penetrate patient anatomy; wherein the elongated curvilinear shaft of the surgical needle is curved in the longitudinal direction, and the elongated curvilinear shaft includes an arcuate surface extending along at least a portion of the curvilinear shaft, the arcuate surface having an arc component oriented in the longitudinal direction and a flat component oriented in a direction transverse to the longitudinal direction, and wherein the arcuate surface is dimensioned to contact a pubic symphysis during the retropubic midurethral sling procedure to provide at least one of tactile confirmation of needle orientation, visual confirmation of needle orientation, and improved needle tracking during an advancement of the needle into the patient along the pubic symphysis. ### Claim 18 (depends on 17) The implant delivery system of claim 17, wherein the elongated curvilinear shaft of the surgical needle has a concave side and a convex side. ### Claim 19 (depends on 18) The implant delivery system of claim 18, wherein the arcuate surface is positioned on the concave side.
