Abstract
Abstract An occluding member, for being lodged in an oviduct where it narrows, e.g. at the junction between the ampulla and the isthmus, includes a tapered base portion and a narrowed forward portion. A suture attached to the occluding member is passed through an opening in the wall of the oviduct and is wrapped about the oviduct to occlude its walls against the forward portion of the occluding member. For inserting the occluding member, a separable rod passes the member through the inlet of the oviduct until it is lodged. Over the forward portion of the occluding member is temporarily positioned a suture guide, which holds the suture forward of the occluding member forward portion during positioning the occluding member and forms the opening in the wall of the oviduct. After the suture is drawn out of the oviduct through the opening in its wall, the suture guide is removed through the same opening in the oviduct wall.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
100 words
A device for occluding an oviduct comprising, an occluding member having a base portion of a first width contoured to lodge in the oviduct and to be engaged by the walls thereof; a securing means attached to said occluding member for being secured to said oviduct and for holding said occluding member in position; a narrowed width forward portion narrower than said first width for extending into the oviduct; a forward end of said occluding member forward of said forward portion; said securing means being positioned and adapted to occlude the oviduct about said forward portion of said occluding member.
Claim 2
Independent Claim
100 words
A device for occluding an oviduct comprising, an occluding member having a base portion of a first width contoured to lodge in the oviduct and to be engaged by the walls thereof; a securing means attached to said occluding member for being secured to said oviduct and for holding said occluding member in position; a narrowed width forward portion narrower than said first width for extending into the oviduct; a forward end of said occluding member forward of said forward portion; said securing means being positioned and adapted to occlude the oviduct about said forward portion of said occluding member.
Claim 3
Dependent Claim
16 words
The occluding device of claim 1, wherein said occluding member is comprised of an inert material.
Claim 4
Dependent Claim
38 words
In combination, the occluding device of claim 1 and an insertion element for inserting said occluding member into the oviduct; said insertion element being removably secured to said occluding member and being separable therefrom upon completion of insertion.
Claim 5
Dependent Claim
36 words
The combination of claim 3, wherein said insertion element comprises an elongated rod of sufficient length to extend from the inlet of the oviduct to the location at which said occluding member is to be lodged.
Claim 6
Dependent Claim
40 words
The occluding device of claim 1, wheRein said occluding member base portion has a tapering neck leading into said occluding member forward portion, whereby said occluding member lodges in the oviduct at the junction between the ampulla and the isthmus.
Claim 7
Dependent Claim
18 words
The occluding device of claim 1, wherein said securing means comprises a suture secured to said occluding member.
Claim 8
Dependent Claim
62 words
In combination, the occluding device of claim 1, and a securing means guide device removably secured to said occluding member; said securing means being carried by said guide device into the oviduct so as to be positioned thereby for later securement of the securing means so as to enable said securing means to occlude the oviduct about said occluding member forward portion.
Claim 9
Dependent Claim
25 words
The combination of claim 7, wherein said guide device is structured and positioned to carry said securing means forward of said occluding member forward portion.
Claim 10
Dependent Claim
72 words
The combination of claim 8, wherein said guide device comprises a hollow tube which fits over said occluding member forward portion and includes a forward opening which is forward of said occluding member forward portion; said securing means comprising a suture secured to said occluding member; said suture being passed through said guide device tube, and extending out of said forward opening for being held forward of said occluding member forward portion.
Claim 11
Dependent Claim
31 words
The combination of claim 9, wherein said guide device forward opening is defined by a forward end, which is sufficiently rigid and sharp to punch through the wall of the oviduct.
Claim 12
Dependent Claim
34 words
The combination of claim 9 and an insertion element for inserting said occluding member into the oviduct; said insertion element being securable to said occluding member and being separable therefrom upon completion of insertion.
Claim 13
Independent Claim
49 words
A method of occluding an oviduct comprising the steps of: passing an occluding member into the oviduct through its entrance; and lodging the occluding member in the oviduct at the narrowing junction between the ampulla and the isthmus of the oviduct and blocking the oviduct with the occluding member.
Claim 14
Independent Claim
49 words
A method of occluding an oviduct comprising the steps of: passing an occluding member into the oviduct through its entrance; and lodging the occluding member in the oviduct at the narrowing junction between the ampulla and the isthmus of the oviduct and blocking the oviduct with the occluding member.
Claim 15
Dependent Claim
25 words
The method of occluding an oviduct of claim 12, comprising the further step of securing the occluding member in the oviduct where it has lodged.
Claim 16
Dependent Claim
60 words
The method of occluding an oviduct of claim 13, wherein before being passed into the oviduct, the occluding member is positioned on an insertion rod; the occluding member is passed into the oviduct by the rod being passed into the oviduct; the insertion rod is separated from the occluding member after the occluding member has been lodged in the oviduct.
Claim 17
Dependent Claim
48 words
The method of occluding an oviduct of claim 13, wherein before being passed into the oviduct, the occluding member is provided with a securing means; and after the occluding member is lodged in the oviduct, the securing means is secured to hold the occluding member in the oviduct.
Claim 18
Dependent Claim
72 words
The method of occluding an oviduct of claim 15, wherein the securing means is a suture; an opening is made in the wall of the oviduct forward of the location where the occluding member is to be lodged; after the occluding member is lodged in the oviduct, the suture is passed through the opening in the wall and is then wrapped about the oviduct to occlude the oviduct about the occluding member.
Claim 19
Dependent Claim
87 words
The method of occluding an oviduct of claim 16, wherein the suture is passed through a guide device which carries the free end of the suture forward of the occluding member as the occluding member is passed into the oviduct; after the occluding member has been lodged in the oviduct, both the guide device and the suture are drawn through the opening in the oviduct wall, the guide device is then removed from the suture, and the suture is then wrapped about the oviduct to occlude it.
Claim 20
Dependent Claim
47 words
The method of occluding an oviduct of claim 17, wherein after the occluding member has been lodged in the oviduct, the oviduct and guide device are manipulated with respect to each other to cause the guide device to form the opening in the wall of the oviduct.
Claim 21
Dependent Claim
53 words
In combination, the method of occluding an oviduct of claim 15 and a method of removal of the occluding member; the method of removal comprising the steps of releasing the securing means; and squeezing the walls of the oviduct against the occluding member to force the member to shift out of the oviduct.
