Disclosed herein are systems and methods for performing total hip arthroplasty with patient-specific guides Pre-operative images of a pelvic region of a patient are taken in order to predefine the structure of the guides and corresponding implants. From the obtained image data an insertional vector for implanting an acetabular implant or component into an acetabulum of the patient is determined, wherein the insertional vector is coaxial with a polar axis of the acetabular component. Also from the obtained image data, a superior surface of the guides and implants can be shaped to match the acetabulum of the patient. A nub portion extending outwardly from the superior surface of the guides and implants is shaped to substantially match the shape of a fovea of the acetabulum. A guide portion of the guides forming a slot has a longitudinal axis coaxial with the determined insertional vector of a corresponding acetabular component.

Systems and methods treat urologic dysfunctions by implanting a lead and electrode in a tissue region affecting urologic function, and coupling the lead to an external pulse generator.

A spring-loaded, self-retaining, clamp like alignment device used to guide the placement of the acetabular component during total hip arthroplasty is disclosed. The device comprises two longitudinal elements: the first longitudinal element has a proximal end with a handle, a groove within and a spring loaded into the groove.

A prosthesis for addressing pelvic organ prolapse in females comprises a frame fabricated from a shape memory material that supports a thin, flexible mesh sheet in a stretched condition when the frame is unconstrained. The mesh sheet is formed with two finger receiving pockets proximate its posterior periphery to be used by the surgeon in steering the prosthesis to a desired disposition within the pelvic basin. The frame is shaped so as to conform to and be supported by bone structures and muscle tissue in the pelvic basin while providing needed support to pelvic organs to maintain them in a proper position. The use of a shape memory material allows the prosthesis to be rolled or folded into a reduced size for ease of placement through a small incision in the wall of the vagina, but that springs back to its memorized shape following deployment from a delivery sheath.
