- 20. The flexure guide of claim 17, wherein said elongate body is cannulated.
- 21. The flexure guide of claim 17, wherein said elongate body has a circular transverse cross section.
- 22. The flexure guide of claim 17, wherein said elongate body has a polygonal transverse cross section.
- 23. The flexure guide of claim 17, further comprising:
actuation means for actuating said guide shaft into a plurality of flexed positions.
- 24. The flexure guide of claim 17, wherein said elongate body includes a longitudinal bore substantially parallel to and spaced from said longitudinal axis, said flexure guide further comprising:
a cable positioned in said longitudinal bore of said elongate body, said cable having a cable distal end; and prevention means for preventing said cable distal end from being pulled in a distal to proximal direction through said longitudinal bore.
- 25. The flexure guide of claim 24, wherein said prevention means comprises a radial protrusion secured to said distal end of said cable.
- 26. A flexure guide, comprising:
an elongate body having a longitudinal axis, said elongate body having an incomplete cutout formed therein.
- 27. The flexure guide of claim 26, wherein each of said plurality of cutouts is substantially V-shaped.
- 28. The flexure guide of claim 26, wherein said elongate body is cannulated.
- 29. The flexure guide of claim 26, wherein said elongate body has a circular transverse cross section.
- 30. The flexure guide of claim 26, wherein said elongate body has a polygonal transverse cross section.
- 31. The flexure guide of claim 26, further comprising:
actuation means for actuating said guide shaft into a plurality of flexed positions.
- 32. The flexure guide of claim 26, wherein said elongate body includes a longitudinal bore substantially parallel to and spaced from said longitudinal axis, said flexure guide further comprising:
a cable positioned in said longitudinal bore of said elongate body, said cable having a cable distal end; and prevention means for preventing said cable distal end from being pulled in a distal to proximal direction through said longitudinal bore.
- 33. The flexure guide of claim 32, wherein said prevention means comprises a radial protrusion secured to said distal end of said cable.
- 34. A prosthetic implant, comprising:
a bag, said bag formed of a biocompatible material; a fill access providing access to an interior of said bag a tube, said bag secured to an exterior of said tube; and an extension connected to and extending from said tube, said extension including a frangible portion.
