Abstract

A mesh delivery system for sacral colpopexy procedures is disclosed. The system uses a mesh stabilizer (30) that is introduced in a compressed configuration through a surgical port into the abdomen, and a vaginal probe (10) (inserted through the vagina) with a magnetic or non-magnetic head that engages with the mesh stabilizer (30), anchoring it in position. The mesh stabilizer (30) employs a pseudoelastic shape memory alloy, and folds compact to deliver multiple mesh straps or a single Y-shaped surgical mesh in a streamlined configuration into the abdomen for facilitating the sacral colpopexy procedure. After delivery, the stabilizer (30) expands to a functional configuration where it interfaces with the probe (10) head and stabilizes and adjustably feeds the mesh strap(s) for suturing while maintaining stabilization of the mesh on the vaginal apex and while keeping excess mesh from obscuring the surgeons view. After suturing, the stabilizer can be removed back through the surgical port.
