Another aspect of this application is to provide a removal system that delivers dissolving material, agitates, aspirates, and confirms the patency of the bodily lumen following the removal of the occlusive material if so desired by the patient for the return to fertility.

Described are methods for reversible occlusion of a body lumen by way of degradation as a result of exposure to one or more stimuli such as light. The methods include administering one or more substance(s) into a body lumen of a subject and forming a stimuli-responsive polymer mass in the body lumen from the one or more substance(s). The mass is sufficient to occlude the body lumen in a manner that prevents transport of at least one material through the body lumen and is susceptible to on-command reversal in the body lumen upon exposure to one or more stimuli. The methods include administering one or more stimuli to a polymer mass in a body lumen for a time and intensity to cause the reverse the polymer mass. The methods are particular useful for applications in which it is desirable to temporarily occlude a body lumen, such as male and female contraception.
