Method and apparatus for treating pelvic organ prolapse
View Patent ↗An apparatus for treating pelvic organ prolapse in a patent is provided. The apparatus includes a support portion having first and second ends. A first elongated end portion is connected to the first end of the support portion. The first elongated end portion includes a first dilator configured to attach securely with a tip of a needle. A second elongated end portion is connected to the second end of the support portion. The second elongated end portion includes a second dilator configured to attach securely with a tip of a needle. The first and second needles include a straight portion, a tip, a first radius, and a second radius distinct from the first radius. The first radius and the second radius are disposed between the straight portion and the tip. A method and kit for the treatment is further provided.

3. The apparatus of claim 2 , wherein the straight section of the first needle is between about 5 inches and about 7 inches.
4. The apparatus of claim 3 , wherein the straight section of the first needle is between about 5.5 inches and about 6.5 inches.
5. The apparatus of claim 3 , wherein the straight section of the first needle is between about 4.5 inches and about 5.5 inches.
6. The apparatus of claim 2 , further comprising a tool for connecting the tip of the first needle to the dilator of the first elongated portion.
7. The apparatus of claim 2 , further comprising:
a first transition zone disposed between the first elongated end portion and the first dilator; and,
a second transition zone disposed between the second elongated portion and the second dilator,
wherein the first transition zone and the second transition zone are each comprised of a riveted synthetic cape which provides a tapered transition from respective end portion to dilator.
8. The apparatus of claim 1 , further comprising a repositioning means to effect tightening or loosening said apparatus without adversely affecting the therapeutic efficacy of said apparatus.
9. The apparatus in claim 8 , wherein said repositioning means comprises at least one filament threaded along at least one end portion.
10. The apparatus of claim 1 , wherein the diameter of said first needle is between about 0.100 inches and about 0.150 inches.
11. The apparatus of claim 1 , wherein the straight section of the first needle is between about 3 inches and about 7 inches.
12. A kit for repairing pelvic organ prolapse in a patient utilizing a posterior perirectal tissue pathway comprising:
a support member comprising a support portion and two end portions, wherein at least one of said end portions further comprises a removable plastic sheath;
a first needle comprising a first handle, a first tip, a straight portion, and a curved portion between the straight portion and the tip, the curved portion having a first radius of curvature, and a second radius of curvature different from the first radius of curvature, wherein the first radius of curvature of the first needle is between the tip of the first needle and the second radius of curvature of the first needle, and the first radius of curvature of the first needle is between about 2 inches and about 4 inches and the second radius of curvature of the first needle is between about 4 inches and about 6 inches, and the first needle is configured to form a first pathway through tissue adjacent to said prolapsed organ, said pathway extending between an external perirectal region and a region of an ischial spine of the patient.
13. The kit of claim 12 , further comprising:
a second needle comprising a second handle, a second tip, a straight portion, and a curved portion between the straight portion and the tip, the curved portion having a first radius of curvature, and a second radius of curvature different from the first radius of curvature, wherein the first radius of curvature of the second needle is between the tip of the second needle and the second radius of curvature of the second needle, and the first radius of curvature of the second needle is between about 2 inches and about 4 inches and the second radius of curvature of the second needle is between about 4 inches and about 6 inches, and the second needle is configured to form a second pathway through tissue adjacent to said prolapsed organ, said pathway extending between an external perirectal region and a region of an ischial spine of the patient.
14. The kit of claim 13 , wherein the first radius of curvature of the first needle is located on the same side of the first needle as the second radius of curvature.
15. The kit of claim 14 , wherein the first radius of curvature of the second needle is located on the same side of the second needle as the second radius of curvature.
16. The kit of claim 13 , wherein the first radius of curvature of the first needle is located on the opposite side of the first needle from the second radius of curvature.
17. The kit of claim 16 , wherein the first radius of curvature of the second needle is located on the opposite side of the second needle from the second radius of curvature.
