Abstract:
1. A contraceptive system for occluding a reproductive body lumen to prevent the passage of reproductive cells therethrough, comprising: a) an occluding member, said occluding member being at least in part expandable within the reproductive body lumen from a first configuration to a second expanded configuration, wherein a surface of the occluding member is roughened, coated or seeded to spur ingrowth of tissue cells and secure a wall portion of the reproductive body lumen thereto when in the second expanded configuration; b) means to collapse the expanded part of the occluding member to a smaller transverse cross-sectional dimension so that the wall portion secured thereto collapses thereupon to occlude the reproductive body lumen sufficiently to prevent the passage of reproductive cells therethrough.
