A mesh delivery system (2) for sacral colpopexy procedures is disclosed. The system (2) uses a mesh stabilizer (30), an endoscopic introducer (2) that carries the mesh stabilizer (30) into the abdomen, and a vaginal probe (10) (inserted through the vagina) with a head that interfaces with the mesh stabilizer (30) in lock-and-key fashion. The mesh stabilizer (30) delivers mesh straps for sacral colpopexy into the abdomen. After delivery, the stabilizer (30) interfaces with the probe (10) head and locks the mesh stabilizer (30) with mesh straps in place. The endoscopic introducer (20) can then be temporarily detached and removed to facilitate suturing of the mesh to the anterior and posterior vaginal walls. After permanent suturing, the introducer (20) can be reinserted and used to retrieve the mesh stabilizer (30) component.
