Methods and devices for fallopian tube diagnostics

A device for Fallopian tube diagnostics, comprising:

• a tube having a distal end and positionable relative to the Fallopian tube;
• and
• a balloon having a distal end and coupled to the distal end of the tube at a proximal end of the balloon, the balloon being movable between a first inverted position and a second everted position such that the balloon is extendable in the Fallopian tube in the second everted position;
• and
• a filament disposed at the distal end of the balloon, wherein the filament has a first configuration relative to the balloon in the first inverted position of the balloon, and a second configuration relative to the balloon in the second everted position of the balloon;
• wherein the filament is configured to curl, spread, fan, ball-up, or expand-out, or combinations thereof, in response to the balloon moving between the first inverted position and the second everted position;
• wherein the balloon is inelastic, such that in response to moving between the first inverted position and the second everted position, over-expansion of the Fallopian tube by the balloon is preventable.
