Schneider, 2544 E. 21st St., Brooklyn, N.Y. 11235 Filed Feb. 10, 1965, Ser. No. 431,634 Int. Cl. A61f /46 U.S. Cl. 128-130 5 Claims ABSTRACT OF THE DISCLOSURE A contraceptive appliance of four parts; an intrauterine plug, a seating tube, having at one end a flexible flange, for proper seating; a rod for pushing the plug through the tube; a removal device; all parts working through the aforementioned tube.

A contraceptive device that prevents conception by blocking and retarding the passage of male sperm from the vagina to the uterus. The device for doing this consists of four parts. An intrauterine plug, a one-piece device, having a shank with ends of two ball-like shapes, made of stainless steel or plastic. The plug is inserted into the cervix by the use of the seating tube and push rod. The seating tube is a hollow plastic tube with a flange that flares out at the bottom end of the tube in a semicompleted oval shape; this acts as a guidance device in seating of the plug by adjusting to the vaginal walls. When inserted, the uterine plug can remain for as long as a month. A removal device makes up the fourth part.

FIG. 1 is a perspective view, partly in section, showing the position of the device in the inserting mechanism;

FIGURE 2 is a perspective view of the extractor used for removing the intrauterine device.

FIGURE 3 is a diagrammatic view of the device in position in the uterus canal;

FIGURE 4 is a perspective view of the intrauterine plug; and

FIGURE 5 is a top end view of the embodiment shown in FIGURE 1.

The description of the drawings is as follows: FIGURE 1 consists of a hollow tube, that has a flared portion 3, at the bottom thereof on the drawings. The device of FIGURE 2 is the removal rod with four metal or plastic fingers molded into the rod. The springs 6, 7, 8, and 9 are bent out, then bent half-way down, then bent in, a like amount. FIGURE 3 shows the device seated in the vagina 12 with the intrauterine plug in place in the cervix and the uterus canal .11. This figure is also shown cut away at the bottom. FIGURE 4 is the intrauterine plug with ball-like ends 4 and shank 5, which fits the seating tube of FIGURE 1; and moved in the tube by seating rod 2. FIGURE 5 is a top end view of FIGURE 1; showing the circular, flared portion of the bottom 3; the inner circles are the tube 1, and the seating rod 2, respectively.

There are many contraceptive devices that are patented, each seeking a solution to the problem; but the fact that they have all but a few, not found acceptance and use, seems to indicate that they have inherent defects in their makeup, and an improved or better device seems to be indicated. The main problem is in the female devices; the acceptable one is a very short period device. Others are elaborate devices, causing discomfort, and the person using them prefer pregnancy to prevention. One device depends on body chemistry for removal, a chancey proposition. The solution seems to be in a device that is small, but effective; that after a short period of time in use, would by the person using it, forget that it was even there. A simple device for seating, another for removing United States Patent 0 3,441,018 Patented Apr. 29, 1969 "ice it, completes the picture. FIGURE 1 in the drawing is the seating tube of slippery, flexible plastic, with an even 'more flexible flange. The flange flexes and when being seated, will decrease and increase in size, fitting the walls of the vagina as it is put in, keeping the tube portion centered in the vagina, and so is easily guided into the proper position for seating. The intrauterine plug of FIGURE 4. The rod 2, shown in the tube of FIGURE 1, is the seating rod, and is used to move the intrauterine plug in the tube, and then at proper time, push it into the cervix and the canal, sealing it. The seating rod is molded of the same type plastic as the plastic tube currently found on the market. The tube and the rod are removed after the plug is in place. The tube, the flange, and the plug can be made in various sizes, since women are not all built alike. The bottom flange, shown in FIGURE 5, completely circumscribes the tube and an intrinsic part of the tube. The shape is an incomplete oval. There is a space between the tube and the end of the flange to allow for flexing, and said flange tapers toward its end.

The intrauterine plug as indicated in FIGURE 4, has a long round shank with ends forming two ball-like shapes. The reasoning that dictated this choice of shapes is this; when inserted into the uterus canal, the walls will surround it and act as an anchor to prevent it from being dislodged. The roundness and biologically compatibility of materials keep the tissue adhering to the intrauterine plug, making a tight seal fit. The nonirritating material will also discourage the body from dislodging the plug. The two ball-like shapes and the shank all aid in blocking, or greatly impeding the sperms progress and because of its short life span, never reaches its goal. Being small and compatible of shape, made of materials of plastics or stainless steel, of the types used in dentistry; injection molded, or precision cast. This device should be able to stay in, much like dentures, for periods as long as a month; when it can easily be removed by the device in FIGURE 2 for the menstrual cycle. The extractor of FIGURE 2 is a flexible, plastic rod-like device, the same as the rod marked 2, but the ends are different. The rod 2 has a concave end, which fits the top of the intrauterine plug. The rod in FIGURE 2 has ends of four steel or plastic springs, molded into the plastic, extending out, as shown in the drawing, making a square-shaped figure at their extremities. The springs are per permently bent out, then in and, as illustrated by 6 to 9 on the drawing. Number 8 is the front spring, 7 is the back spring. The extractor fits into the tube 1, and the springs contract until they reach the end, then they again open. In the open position, with a little force they surround the ball. The ball is then drawn partially into the tube. The whole device, the tube, extractor, and intrauterine plug are all removed from the vagina. FIGURE 3 shows the seating device in the vagina 12, the uterus is 10, and the uterus canal is 11. All of the devices described will have to be initially fitted, and the patient educated in its use by a doctor for maximum effectiveness and satisfaction.

This ends the description and the specification.
