Abstract:
A plug for reversibly blocking a fallopian tube of a mammal comprising:an elongated support member dimensioned for lengthwise insertion into a mammalian fallopian tube; and a plurality of flexible finger protrusions affixed in spaced-apart relation along and attached at a first end to the support member, the protrusions each having a second end opposed to the first end, the second end free of attachment with the support member, a portion of the protrusion extending from the second end forming a blocking portion adapted for movability between a first position generally adjacent the support member dimensioned for insertion into the fallopian tube and a second position extending radially outward from the support member, the blocking portions in the second position positioned and adapted collectively to form a barrier sufficient to prevent a passage of an ovum or a spermatoazoon in an axial direction thereby.
