Abstract
A method for sterilizing a female or male patient is provided. The method comprises introducing into a reproductive duct of the patient a composition comprising a nucleophilic component, such as a thiol, and a component containing a conjugated unsaturated bond, such as an acrylate. The composition crosslinks within the reproductive duct. Within a female patient, the composition is introduced into one or both uterine tubes. The composition gels in the uterine tubes, thereby blocking the uterine tubes and preventing conception.
Claims25
A method for sterilizing a patient comprising introducing into a reproductive duct of the patient a composition comprising a nucleophilic component and a component containing a conjugated unsaturated bond, whereby the composition undergoes crosslinking within the reproductive duct.
A method for sterilizing a female patient comprising introducing into at least one uterine tube of the patient a composition comprising a nucleophilic component and a component containing a conjugated unsaturated bond, whereby the composition crosslinks within the at least one uterine tube.
A method for sterilizing a male patient comprising introducing into at least one ejaculatory duct and/or the vas deferens of the patient a composition comprising a nucleophilic component and a component containing a conjugated unsaturated bond, whereby the composition cross-links within the at least one ejaculatory duct and/or the vas deferens.
