disconnecting the needle from the second end of the composite band; and
extracting the two parts of the sheath, thus releasing the supporting strip below the urethra.

disconnecting the needle from the composite band; and
extracting the two parts of the sheath, thus releasing the supporting strip below the urethra.
-
-
29. Method for placement or implementation of a surgical assembly according to claim 8, comprising:
-
inserting the needle downward, on a first side of the patient, through the abdominal wall of the patient, bypassing the bladder of the patient and emerging through the vagina of the patient, thus engaging the composite band in the bodily path thus created when the connecting means is outside the vagina;
cutting one side of said composite band to create two parts, one part remaining inside said path and the other part outside the vagina;
inserting the needle connected to the other part of the composite band downward from the second side of the abdominal wall, bypassing the bladder and emerging through the vagina, thus engaging said other part of the composite band in the bodily path so created;
cutting the emerging portion of said other part of the composite band;
pulling on the two parts of the sheath, thus stripping the two parts of the composite band and putting said flexible piece in place;
applying subpubic traction to the two parts of the composite band in order to bring the flexible piece to a suburethral position; and
withdrawing the two parts of the sheath to release the supporting strip.
-
-
30. Method for placement or implementation of a surgical assembly according to claim 14, comprising:
-
a) inserting the needle through the abdominal wall of the patient from a subpubic incision until it emerges from the vagina of the patient;
b) connecting the distal end of the needle emerging from the vagina to said tubular portion of one of the two ends of the composite band;
c) retracting the needle so as to engage the composite band through the bodily path that the needle has created until the composite band emerges at a subpubic level;
d) repeating steps a)-c) on the other side of the pelvis of the patient; and
e) withdrawing the two sheath parts thus putting the strip in place.
-
-
31. Method for placement or implementation of a surgical assembly according to claim 17, comprising:
-
a) inserting said curved, sharp part through the bodily tissues through the foramen of the pelvis until the curved, sharp part emerges from the vagina of the patient, said flexible inner portion being in the advanced position, b) retracting said flexible inner portion;
c) engaging the tubular portion of one end of the composite band with the harpoon-shaped distal end of said rigid outer portion;
d) withdrawing said curved, sharp part in order to engage the composite band through the bodily path created by the curved, sharp part;
e) repeating steps a)-d) on the other side of the pelvis;
f) withdrawing the two sheath parts; and
