Abstract
Abstract A contraceptive device for placement in a fallopian tube includes expanding distal and proximal anchor members and an expandable elongate member connecting the distal anchor member to the proximal anchor member. An expandable material is disposed on at least a portion of the contraceptive device, whereupon delivery of the contraceptive device, the expandable material expands to completely occlude the fallopian tube. The expandable material may contain a drug, therapeutic agent, or hormone which is released over time to occlude or otherwise prevent the passage of spermazoa through the fallopian tube, or prevent ovulation. The contraceptive device may be delivered non-operatively and provide complete sterilization within a period of days. The device and delivery method obviates the need for follow-up visits to confirm closure of the fallopian tubes.

Claim 11
Dependent Claim
122 words
10 . An apparatus for placement of a contraceptive device in a fallopian tube comprising: a delivery member having a lumen passing from a proximal end to a distal end; a contraceptive device adapted for disposal within the lumen of the delivery member, the contraceptive device comprising: an expanding distal anchor member; an expanding proximal anchor member; an expandable elongate member connecting the distal anchor member to the proximal anchor member; an expandable material disposed on at least a portion of the contraceptive device, whereupon delivery of the contraceptive device, the expandable material expands to completely occlude the fallopian tube; and a pusher member slidable within the lumen of the delivery member, the pusher member being located proximal of the contraceptive device.
Claim 12
Dependent Claim
122 words
10 . An apparatus for placement of a contraceptive device in a fallopian tube comprising: a delivery member having a lumen passing from a proximal end to a distal end; a contraceptive device adapted for disposal within the lumen of the delivery member, the contraceptive device comprising: an expanding distal anchor member; an expanding proximal anchor member; an expandable elongate member connecting the distal anchor member to the proximal anchor member; an expandable material disposed on at least a portion of the contraceptive device, whereupon delivery of the contraceptive device, the expandable material expands to completely occlude the fallopian tube; and a pusher member slidable within the lumen of the delivery member, the pusher member being located proximal of the contraceptive device.
