Abstract
Abstract Contraceptive methods, systems, and devices generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. The contraceptive device may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues, by manipulating one or more actuators of a proximal handle with a single hand. This leaves the other hand free to manipulate a hysteroscope, minimizing the number of health care professional required to deploy the contraceptive device.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
160 words
A contraceptive delivery system comprising: a contraceptive device 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 contraceptive device; 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 an 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 contraceptive device and affixing the contraceptive device within the ostium of the fallopian tube.
Claim 2
Dependent Claim
160 words
A contraceptive delivery system comprising: a contraceptive device 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 contraceptive device; 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 an 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 contraceptive device and affixing the contraceptive device within the ostium of the fallopian tube.
Claim 3
Dependent Claim
13 words
The contraceptive delivery system of claim 1 , further comprising an anchoring structure.
Claim 4
Dependent Claim
29 words
The contraceptive delivery system of claim 1 , further comprising conductors extending along the sheath and along the first elongate body to provide resistive heating of the contraceptive device.
Claim 5
Dependent Claim
28 words
The contraceptive delivery system of claim 1 , further comprising a means for energizing the first elongate body with radiofrequency energy to provide a large return electrode path.
Claim 6
Dependent Claim
103 words
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; and detaching the contraceptive device from the elongate body within the ostium to inhibit conception.
Claim 7
Dependent Claim
103 words
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; and detaching the contraceptive device from the elongate body within the ostium to inhibit conception.
Claim 8
Dependent Claim
17 words
The contraceptive method of claim 5 , further comprising anchoring the expanded contraceptive device within the ostium.
Claim 9
Dependent Claim
24 words
The contraceptive method of claim 5 , further comprising providing heat to the contraceptive device before detaching the contraceptive device from the elongate body.
Claim 10
Dependent Claim
26 words
The contraceptive method of claim 5 , further comprising energizing the first elongate body with radiofrequency energy before detaching the contraceptive device from the elongate body.
Claim 11
Dependent Claim
116 words
A contraceptive delivery system comprising: a contraceptive device insertable into an ostium of a fallopian tube; a deployment shaft having a proximal end and a distal end releasably coupled to the contraceptive device; a proximal handle connected with the proximal end of the deployment shaft, the handle having a size and shape suitable for gripping with a single hand; an 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 releases the contraceptive device from the distal end of the deployment shaft; and conductors extending along the deployment shaft to provide energy to at least a portion of the fallopian tube.
Claim 12
Dependent Claim
116 words
A contraceptive delivery system comprising: a contraceptive device insertable into an ostium of a fallopian tube; a deployment shaft having a proximal end and a distal end releasably coupled to the contraceptive device; a proximal handle connected with the proximal end of the deployment shaft, the handle having a size and shape suitable for gripping with a single hand; an 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 releases the contraceptive device from the distal end of the deployment shaft; and conductors extending along the deployment shaft to provide energy to at least a portion of the fallopian tube.
Claim 13
Dependent Claim
17 words
The contraceptive delivery system of claim 9 , wherein the deployment shaft additionally comprises a core shaft.
Claim 14
Dependent Claim
16 words
The contraceptive delivery system of claim 9 , wherein the deployment shaft comprises a release catheter.
Claim 15
Dependent Claim
25 words
The contraceptive delivery system of claim 9 , wherein the distal end of the deployment shaft is releasably coupled to the contraceptive device by threads.
Claim 16
Dependent Claim
19 words
The contraceptive delivery system of claim 9 , wherein the conductors extending along the deployment shaft provide resistive heating.
Claim 17
Dependent Claim
14 words
The contraceptive delivery system of claim 9 , wherein the conductors provide radiofrequency energy.
