URETHRAL SLING IMPLANTATION USING NEEDLE SHEATHS

摘要

Instruments for implanting a urethral sling in female patients, and a better technique for implanting the sling, are disclosed. Porcine small intestine submucosa is processed into a sturdy yet assimilable sling for supporting a urethra of a female patient. The sling is implanted using ligature carriers and sheaths to minimize contact between the sling and the vaginal and abdominal tissues of the patient. The ligature carriers are implanted into the patient via a suprapubic or vaginal route (antegrade or retrograde). The sling is then attached to the ligature carriers and is drawn into the patient through the sheaths. Then sheaths are then removed and the sling is adjusted and trimmed.
