"PESSARY' i George A.. Clark, llwmndl,llielxrf.,V Application May-s, 1945senal Ne. er-,issie` (o1. raaf-131) Y l 5- Claims.

The present invention relates to pessaries and' has for an object to provide a flexible device suchthat it conforms readily to theA contour of the canal' and cavity of a user upon insertion, fthev4 parts of which are housed in rubberwhereby no metallic portions can come in contact `with theflesh.

Another object of the invention is to provide.l

A still further object is, to provide an improved" structure with respect to my prior Letters Patent of the United States, numbered 1,896,071,1issued" Februaryf'l, 1933, for Pessaries.

Other and further objects and advantages of the invention will be understoodfrom the follow-1 ing detailed description thereof, reference being had to the accompanyingl drawing, in which:`

Figure 1 is a side'view of the new device applied in a position of' use to a uterus, the latter-being being represented by dottedA lines.

Figure 2- is a longitudinal sectional Viewy of theI pessary shown in Figure 1.

Figure 3 is a top plan view thereof. Figure 4 is a longitudinal section expander employed.

Figure 5 is a transverse section of7 the covermember of the invention. It is well known that the neck of the uterus is of' a canal made up of both circular and longitudinal' fibresof muscle and does not-bend. The body is more fiaccid and will flex and bend inY all directions. It is also well yknown that the huma-n uterus isv often of abnormalshape and size ,andV that the canal, in the middle of the neck of' the uterus;

is larger than the outer or cervical portion and? the inner, where the neck-V joins the bodyI off the organ, and that there is a comparatively sharp bend in the uterus which causes trouble in thepractice of gynecology and obstetrics and-"the`r present invention aims` to provide a pessary; theparts of which are so constructed that it is pliable enough to, follow theA cavity of the organ without causing pressure and` resultant symptoms of cramps, bleeding and nervousness.

thereby snugly conforms to the'adjacent tissues and the member I6 holds thatl portion, selected,

movement of the member I6'toward. the mouth .3

of the uterus, in order to prevent a movement in a reverse direction, the following outlined procedure is practiced:

That end of the shank with respect to the wings I2 and I 3 is cut off toprovidethe end 33 of the shank I0 of adequate, proportiona1 length and so that a' portion of a link of the chainl 2| projectsoutwardly of said end 33. The next adjacent link is then severed and discarded. Y l

lThe said projecting portion of, the said end link is then hooked tothe connector 23 and the opening of the latter is'closed to lock the head I I to 'the shank IIJ, whereby ,the wall 2,5 of the well 24 extends an appreciable distance beyond the end 33 -of the shank I II fonpre'venting contact of metal with tissue, as shown in Figure 1, and the head and shank are', in operative eiect, the

same as if made initially'integral or joined,'while at the same time, fitting; adjusting and main# taining the whole' devicetofsuit the requirements of an individual user," as prescribed and processed by the" physician, for therapeutical purposes. 1

' It will be seen'that the-construction is such that since the opening ITIf-of-the-member II6 is larger in diameter than'the shank Ill that the flexible shank, adj'acent'fits end 33;"is permitted to move from side to during use. I A l 1 As thus described, it'will'also be 'seen that when the new device is applied'to pathological 'conditions, including congestion and'mal-positi'ons 'of the uterus, the new device tends'to return vit to its normal state of health, also promoting later conception insterile females' and that, during use, the new'device stimulates' the nerves and muscles` massaging the endometrium without applying pressure to anyL'olf-'the parts of the uterus 'side of the" opening I 'I freely during all conditions of use.=
