The Altis Single Incision Sling System is indicated for the treatment of female stress urinary incontinence (SUI) resulting from urethral hypermobility and/or intrinsic sphincter deficiency (ISD).
The Altis System is a single-incision mini-sling.. The sling material is manufactured using the commercialized Aris polypropylene mesh (K050148). Altis sling is made of a 0.08mm (nominal) diameter monofilament polypropylene mesh, knitted into a sling 1.1 cm wide by 7.75 cm long. One end of the sling assembly connects to a short length of USP size 1 monofilament polypropylene suture and to a polypropylene static (non-tensioning) anchor. The second side of the sling assembly terminates to a longer section of USP size 1 monofilament polypropylene suture. This suture is then positioned through the second anchor that is dynamic with an integrated tensioning system. The tensioning capability is accomplished by threading the suture through a polyurethane tensioning collar which is assembled onto the anchor. The anchor/suture assembly wraps around the anchor, resulting in a gap between the anchor and the collar providing constant pressure on the suture, preventing it from moving on its own, or during a pelvic stress event. Tensioning is achieved by pulling on the suture loop, thus applying increased tension of the sling to the urethra until desired support is achieved. The Altis anchors perform an acute mechaning the desired position and tension through the acute post-operative tissue healing and in-growth phase, The Altis sling assembly is packaged with two (2) helical type introducers (one right, one left) that are used to place the sub-urethral sling. The Altis introducers are designed with the appropriate curvature and length to reach the obturator foramen through a single vaginal incision. The tip of the needle is designed to fit into the anchors to facilitate placement into the obturator foramen during the surgical implant procedure. The sling assembly pouch and introducers are placed in a tray sealed with a Tyvek lid. The Altis system (implant plus introducers) is provided sterile (ethylene oxide) and is for single use only.

Identification. Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Examples of surgical mesh are metallic and polymeric mesh for hernia repair, and acetabular and cement restrictor mesh used during orthopedic surgery.(b)
