Methods and apparatus for implanting a stimulation lead in a patient's sacrum to deliver neurostimulation therapy that can reduce patient surgical complications, reduce patient recovery time, and reduce healthcare costs. A surgical instrumentation kit for minimally invasive implantation of a sacral stimulation lead through a foramen of the sacrum in a patient to electrically stimulate a sacral nerve comprises a needle and a dilator and optionally includes a guide wire. The needle is adapted to be inserted posterior to the sacrum through an entry point and guided into a foramen along an insertion path to a desired location. In one variation, a guide wire is inserted through a needle lumen, and the needle is withdrawn. The insertion path is dilated with a dilator inserted over the needle or over the guide wire to a diameter sufficient for inserting a stimulation lead, and the needle or guide wire is removed from the insertion path. The dilator optionally includes a dilator body and a dilator sheath fitted over the dilator body. The stimulation lead is inserted to the desired location through the dilator body lumen or the dilator sheath lumen after removal of the dilator body, and the dilator sheath or body is removed from the insertion path. If the clinician desires to separately anchor the stimulation lead, an incision is created through the entry point from an epidermis to a fascia layer, and the stimulation lead is anchored to the fascia layer. The stimulation lead can be connected to the neurostimulator to delivery therapies to treat pelvic floor disorders such as urinary control disorders, fecal control disorders, sexual dysfunction, and pelvic pain.

An implantable article and method are disclosed for treating pelvic floor disorders such as vaginal vault prolase. A surgical kit useful for performing a surgical procedure such as a sacral colpopexy is also described.

A modular implant system and method for dynamic stabilization of a spine segment that can be implanted in a minimally invasive posterior approach. In one embodiment, the implant device has an inferior body portion configured for fixation in a sacrum or ilium and a superior body portion configured for engaging one or more spinous processes to limit extension and optionally flexion while off-loading a spine segment. The implant system can be configured to stabilize a spine segment, re-distribute loads with the spine segment and still allow spine lateral bending and torsion. Besides being far less invasive than other procedures, the system and method is reversible and adjustable post-implant.

Spinal implants for fusing and/or stabilizing spinal vertebrae and methods and apparatus for implanting one or more of such spinal implants axially within one or more axial bore within vertebral bodies in alignment with a visualized, trans-sacral axial instrumentation/fusion (TASIF) line in a minimally invasive, low trauma, manner are disclosed. Attachment mechanisms are provided that attach or affix or force the preformed spinal implants or rods to or against the vertebral bone along the full length of a TASIF axial bore or bores or pilot holes or at the cephalad end and/or caudal end of the TASIF axial bore or bores or pilot holes. The engagement of the vertebral body is either an active engagement upon implantation of the spinal implant into the TASIF axial bore or a passive engagement of the external surface configuration with the vertebral bone caused by bone growth about the external surface configuration. A plurality of such spinal implants can be inserted axially in the same TASIF axial bore or pilot hole or separately in a plurality of TASIF axial bores or pilot holes that extend axially and in a side-by-side relation through the vertebrae and discs, if present, between the vertebrae. Discectomies and/or vertebroblasty can be performed through the TASIF axial bore or bores or pilot holes prior to insertion of the spinal implants. Vertebroblasty is a procedure for augmentation of collapsed vertebral bodies by pumped-in materials, e.g., bone cement or bone growth materials. Materials or devices can also be delivered into the disc space to separate the adjoining vertebrae and/or into damaged vertebral bodies or to strengthen them.
