Sexual sterilization devices
First Claim
1. A sexual sterilization device comprising a first jaw, a second jaw hingedly connected to said first jaw at a pivot, a resiliently compressible lining on said first jaw, said first and second jaws being hingeable to a clamping position for clamping a genital duct therebetween to effect the occlusion of said genital duct, said lining being in compression when said jaws are in said clamping position, and a stub attached to said second jaw and extending a distance therefrom on the opposite side of said pivot from said second jaw, said stub being engageable with said lining to resiliently bias said first and second jaws apart.

Abstract
A sexual sterilization device has titanium jaws connected at a pivot and internally lined with resiliently compressible silicone rubber. This lining serves to ensure that the lumen of a Fallopian tube remains occluded even after devitalization of the tube tissue. A stub formed on one jaw beyond the pivot engages the lining of the other jaw so urging the two jaws apart. This enables the device to be held easily in an applicator and permits preparatory opening and closing movements of the jaws to be made so facilitating positioning of the device.

4. A sexual sterilization device comprising first and second jaws hingedly connected at a pivot and adapted to be clamped together about a genital duct to effect occlusion thereof;
- a lining of resiliently compressible material provided at least on the first jaw, the lining being in compression when the jaws are clamped together about said duct; and
stub means formed integrally with one jaw at the opposite side of the pivot from said one jaw for engaging part of said lining and imparting tensile strain thereto upon clamping movement of the jaws, tensile forces in said part thereby serving to urge said jaws apart.
- a lining of resiliently compressible material provided at least on the first jaw, the lining being in compression when the jaws are clamped together about said duct; and

5. A sexual sterilization device comprising:
-
a. a first jaw having a clamping portion and pivot means defining a pivot axis; b. a second jaw having a clamping portion and being hingedly connected to said first jaw at said pivot means, the jaws being adapted to be clamped together about a genital duct to effect occlusion therewith; c. A lining of resiliently compressible material provided on the clamping portion of at least the first jaw and being in compression when the jaws are clamped together about a duct, the said lining extending beyond the pivot axis on the fist jaw to define a resilient pad; d. a stub formed integrally with the second jaw at the opposite side of the pivot axis from the clamping portion, the stub being embedded in said resilient pad such that after an initial closing movement of the jaws, the resilience in said pad acting on the stub of the second jaw serves to return the jaws to a fully open position.
