A pelvic organ prolapse treatment device includes an implantable support sized to support and treat a prolapsed organ of a patient, a suture, a knot separate from the suture, and a dilator. The implantable support includes an arm having a first portion connected to a body of the implantable support and an end portion extending away from the body of the implantable support. The end portion of the arm is folded to include a first fold and a second fold that combine to reduce a lateral dimension of a portion of the end portion of the arm. The suture extends away from the end portion of the arm. The knot is provided separately from the suture and is secured around the first fold and the second fold to capture both the end portion of the arm and the suture. The dilator is disposed over and connected to the knot.
