Deployment actuation system for intrafallopian contraception

A contraceptive method comprising:

• inserting a contraceptive device transcervically into an ostium of a fallopian tube by gripping a handle with a hand and moving the hand, the handle coupled to the contraceptive device by an elongate body;
• withdrawing a sheath surrounding the elongate body and at least a portion of the contraceptive device by moving the sheath proximally relative to the elongate body to expose the contraceptive device, such movement effected by moving an actuator on the handle with the hand while the hand grips the handle;
• expanding the contraceptive device by moving the actuator with the hand;
• and
• detaching the expanded contraceptive device from the elongate body so that the contraceptive device remains within the ostium to inhibit conception.

A contraceptive delivery system comprising:

• a contraceptive device having at least a portion which is expandable from a first profile to a second profile, wherein the second profile is larger that the first profile and wherein the at least a portion is insertable into an ostium of a fallopian tube;
• a sheath having a proximal end, a distal end and a lumen therethrough, the lumen forming a receptacle at the distal end, the receptacle configured to releasably receive the at least a portion;
• a first elongate body having a proximal end and a distal end releasably attachable to the contraceptive device, the distal end disposed within the lumen of the sheath and adjacent to the receptacle;
• a proximal handle connected with the proximal end of the sheath, the handle having a size and shape suitable for gripping with a single hand;
• and
• at least one actuator mounted on the handle, wherein movement of the at least one actuator by the hand while the hand grips the handle moves the proximal end of the sheath proximally relative to the handle exposing the at least a portion to allow expansion to the second profile and affixation of the contraceptive device within the ostium of the fallopian tube.

A contraceptive delivery system comprising:

• a contraceptive device having at least a portion which is expandable from a small profile configuration to a large profile configuration, wherein the at least a portion is insertable into an ostium of a fallopian tube when in the small profile configuration;
• a first elongate body having a proximal end and a distal end releasably attachable to the contraceptive device, the distal end disposed adjacent to a receptacle for releasably receiving the contraceptive device;
• a proximal handle connected with the proximal end of the first elongate body, the handle having a size and shape suitable for gripping with a single hand;
• at least one actuator mounted on the handle, the actuator movable by the hand while the hand grips the handle so as to expand the contraceptive device to the large profile configuration and affix the contraceptive device within the ostium of the fallopian tube;
• a sheath having a proximal end, a distal end and a lumen therethrough, the lumen at the distal end slidably receiving the receptacle so that movement of the at least one actuator moves the sheath relative to the handle withdrawing the sheath proximally from the contraceptive device;
• and
• means for expanding the uncovered contraceptive device, the expansion means coupled to the contraceptive device and operable by the at least one actuator after the sheath is withdrawn proximally of the contraceptive device so that expansion of the contraceptive device does not impede proximal movement of the sheath.

A contraceptive delivery system comprising:

• a contraceptive device having at a least a portion which is pre-formed and resiliently expandable from a small profile configuration to a large profile configuration, wherein the at least a portion is configured for insertion into an ostium of a fallopian tube when in the small profile configuration;
• a sheath having a proximal end, a distal end and a lumen therethrough, the lumen forming a receptacle at the distal end, the receptacle configured to releasably receive the at least a portion;
• a first elongate body having a proximal end and a distal end releasably attached to the contraceptive device;
• a proximal handle connected with the proximal end of the first elongate body, the handle having a size and shape suitable for gripping with a single hand;
• and
• at least one actuator mounted on the handle, wherein movement of the at least one actuator by the hand while the hand grips the handle moves the proximal end of the sheath proximally relative to the handle exposing at least a portion of the contraceptive device to allow resilient expansion to the large profile configuration and affixation of the contraceptive device within the ostium of the fallopian tube.
