Abstract
A device for occluding a cervix has an elongated conduit sized and shaped to extend from a proximal end outside the vagina to a distal end near the cervix. A loop sized to fit around an exocervix is provided at the distal end. The loop is sufficiently flexible to be tightened and loosened around the exocervix. The device has a rod inside the conduit. The rod has a distal end and a proximal end, and the loop is joined to the distal end of the rod. Moving the rod longitudinally relative to the conduit tightens or loosens the loop.
Claims19
A device for occluding a cervix of a human through a vagina, comprising:
- an elongated straight conduit sized and shaped to extend from a proximal end outside the vagina to a distal end near the cervix;
- a loop sized to fit around an exocervix, the loop being sufficiently flexible to be tightened and loosened around the exocervix, wherein a portion of the loop is disposed inside the conduit and a portion of the loop protrudes from the distal end of the conduit;
- a hysteroscope that passes through the loop before the loop is tightened around the exocervix;
- and
- an actuator for causing the loop to be tightened and loosened around the exocervix.
