Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
107 words
A method for fallopian tube occlusion comprising the steps of: inserting into a fallopian tube a sheath containing a retention member having a plurality of struts in a reduced profile position; exposing the retention member from the sheath to enable the struts to expand to an expanded position to engage a wall of the fallopian tube; subsequently inserting mesh material within a space between the plurality of struts in the expanded position in situ; and withdrawing the sheath to leave the retention member in the fallopian tube so the mesh material fills the space within the struts to block passage of an egg through the fallopian tube.
