3 Claims. (Cl; 128-130) This invention relates to a pessary, more particularly of the type of uterine pessary used in the treatment of pathological conditions and anatomical fiexions of the cervical portion of the 5' uterus.

The principm object of the present inventionis to provide a self-retaining pessary which will prevent the entrance of foreign substances into the cavity of the uterus, and yet will not interfere with the flow of discharges from the uterus.

Another object of the invention is to so construct the pessary that when in place, its stem portion will be maintained out of contact with the walls of the cervical canal.

A further object is to provide a pessary for the correction of anatomical fiexions of the cervix uteri by means of which a firm yet gentle pressure may be applied to any desired points in the cervical canal.

Other objects and advantages reside in the detail construction of the invention, which is designed ,for simplicity, economy, and efliciency. These will become more apparent from the following description. 1

In the following detailed description of the invention reference is had to the accompanying drawing which forms apart hereof. Like numerals refer to like parts in all views of the drawing and throughout the description. I

In the drawing:

Fig. 1 is a perspective View of a preferred form of the complete pessary. In this view the invention' is illustrated approximately full size.

Fig. 2 is a magnified, longitudinal section through the pessary of Fig. 1.

Fig. 3 illustrates an alternate form of wire stiffener for the pessary.

Fig. 4 illustrates how the alternate form may be embedded in a rubber head instead of the 40 metal head originally illustrated.

The preferred form of the pessary comprises a relatively stiff wire stem 10 terminating at its outer extremity in a fixed bottom 11. At its innet extremity the stem is bifurcated to form two resilient retaining prongs 12, which in turn terminate in bulbous ends 13. As thus far described, the

pessary is similar to the usual stem pessary, ex-

is a series of flexible, hollow, cone-shaped valves or guards 15 along the stem thereof. These guards are preferably formed of very thin rubber, and may be secured on the stem in any desired manner. Any desired number of .the guards may be employed.

A preferred form of the construction is illustrated in the drawing, in whichthe entire stem and the prongs 12 are coated with a covering of .rubber 16. The guards 15 are then placed upon additional dippings or coatings, after which, the

rubber may be cured, preferably by-the air or gas curing processes. This forms the guards and the stem coating into an integral rubber unit;

The above is only suggested as one method of manufacture. The guards might be made and secured to the stem in other manners and the device could be rubber plated by any of the commercial processes.

In use the pessary is inserted into the cervix as is usual with stem pessaries. The insertion 185 may be done with any of the standard pessary introducers or may be accomplished by placing one-half of a soluble capsule over the prongs 12 so as to hold them together until the pessary is in place. The dissolving of the capsule will then allow the prongs to separate within the uterus so as to retain the pessary in place, The button 11 limits the amount of insertion of the pessary. When in place, the natural resiliency of the cones or guards 15 causes them to tend to expand outwardly against the walls of the cervical canal so as to exert a continuous gentle pressure to cor- -rect abnormal anatomical flexions. This pressure may be applied to any desired point orpoints along the cervex uteri by choosing a pessary with the proper number of guards positioned at the proper points along the stem.

It is desired to call attention to the fact that the ,guardspress outwardly withequal pressure .in

that when inplace the base'ofthe cones will toward cs externum, thereioredrainage from the 31':

body ofthe uterus or the cervical canal is not interrupted asit can readily flow past the edges of the flexible cones. However this arrangement 01 the cones causes them to act as guards or check valves to prevent the entrance of foreign substances from the vagina into the uterus. The outwardly flared position of the cones also causes them to have a tendency to constantly urge the pessary inwardly toward the uterus so as to increase the self -retaining qualities of the pessary and relieve the pressure usually exerted on the walls of the uterus by the prongs 12.

The pessary may be constructed as illustrated in Figs. 3 and 4 in which a spring wire, such as piano wire 1'7, is bent back upon itself and twisted as shown at 18. The bent back portion is flattened such as indicated at 19, to form a head, and the extremities are turned back upon themselves as shown at 20. The entire wire thus formed is encased in rubber as in the previous forms. The flattened head of the wire is completely encased in a soft rubber button 21. I

While specific materials andv forms of the improvement have been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:-

1. A pessary comprising: -a stem; a button formed on one extremity of said stem; a rubber casing surrounding said stem; and a series of hollow, flexible, cone-shaped members spaced along said stem with their apexes directed away from said button, said members being secured to said casing.

2. A pessary comprising: a stem; a button formed on one extremity of said stem; a rubber casing surrounding said stem; and a series of hollow, flexible, conehaped members spaced along said stem from said button, said members being formed integrally with said casing.

3. A pessary comprising: a stem; a button formed on one extremity of said stem; a rubber casing surrounding said stem; and a series of hollow, flexible, cone-shaped members spaced along said stem with their apexes directed away from said button, said members being formed integrally with said casing; and a bifurcated flared portion on the other extremity of said stem, said latter portion being enclosed by said casing.
