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.

A prosthesis for addressing pelvic organ prolapse in females comprises a frame comprising first and second segments or halves fabricated from a shape memory material that together support a thin, flexible sheet in a stretched condition when the frame is unconstrained. 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. By providing a two-piece segmented frame, removal of the frame structure post implantation of the prosthesis is facilitated.

A method of repairing a pelvic floor disorder and a system for carrying out the method are provided. The method is effected by positioning an imaging device in an abdominal, rectal, perianal or vaginal cavity, advancing a surgical instrument through a vaginal wall under guidance of the imaging device to thereby reach a target tissue and using the surgical instrument to attach the tissue repair device to the target tissue.

The invention discloses a grid-shaped bracket composite membrane of a pelvic floor repairing belt. The grid-shaped bracket composite membrane of the pelvic floor repairing belt consists of a membrane absorbed by a human body, and a grid-shaped bracket which is not absorbed by the human body. A substrate membrane consists of degradable natural or composite materials which can be absorbed and metabolized by the human body, and a transplant can be almost absorbed and metabolized after a surgery to reduce permanent transplants in the human body to the maximum degree and lower rejection reaction risks. If the transplant is completely absorbed, diseases always recur after the surgery, and therefore, a grid bracket which can not be absorbed is designed in the transplant. On one hand, the grid bracket is used as a template of the transplant, and on the other hand, tissues around the grid bracket react to cover the bracket to form scar compound which takes autologous scars as a fixed dissection structure after the plant substrate membrane is absorbed and metabolized. If necessary, a marker line through which x ray can not penetrate is added into the transplant for knowing the position of the transplant in the pelvic floor after the surgery, and the marker line can be used for conveniently positioning, observing and carrying out follow-up visit on the composite membrane structure after the surgery. According to the structure, a current technical problem of the transplant for a pelvic organ prolapses surgery of middle and old aged women can be favorably solved.
