Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
In an entirely intra-vaginal device aid in controlling incontinence in females, the improvement of said device comprising a central portion of an arcuate cupped configuration and shaped to be retained, within the vagina of a user, in an upwardly convex orientation, a rearward portion extending rearwardly from said central portion to engage the posterior vaginal wall, a forward portion extending upwardly from said central portion to engage the anterior vaginal wall adjacent the bladder neck and to lift the bladder portion located adjacent thereto, a bladder neck cradle which is a depression provided at the top of said forward portion positioned to cradle the bladder neck, and wherein said device is formed of resiliently deformable material so as to flex into engagement with the posterior and anterior vaginal wall to retain the device in its upwardly convex position with the forward portion lifting the bladder and cradling the bladder neck.
Claim 2
Dependent Claim
150 words
In an entirely intra-vaginal device aid in controlling incontinence in females, the improvement of said device comprising a central portion of an arcuate cupped configuration and shaped to be retained, within the vagina of a user, in an upwardly convex orientation, a rearward portion extending rearwardly from said central portion to engage the posterior vaginal wall, a forward portion extending upwardly from said central portion to engage the anterior vaginal wall adjacent the bladder neck and to lift the bladder portion located adjacent thereto, a bladder neck cradle which is a depression provided at the top of said forward portion positioned to cradle the bladder neck, and wherein said device is formed of resiliently deformable material so as to flex into engagement with the posterior and anterior vaginal wall to retain the device in its upwardly convex position with the forward portion lifting the bladder and cradling the bladder neck.
Claim 3
Dependent Claim
32 words
The device claim 1 wherein said rear portion is a pair of rearwardly extending projections, and said forward portion is a pair of upwardly extending projections, between which said cradle is located.
Claim 4
Dependent Claim
23 words
The device of claim 2 wherein said central portion has an aperture to provide for the discharge of menstrual blood and vaginal secretions.
Claim 5
Dependent Claim
14 words
The device of claim 3 wherein said device is integrally moulded from elastomeric material.
Claim 6
Dependent Claim
64 words
In an entirely intravaginal urinary incontinence device, the improvement comprising a resilient annular body defining an annulus, the annular body having integrally formed on respective portions thereof two projections that project, at least in part, correspondingly transversely to the annulus of the annular body, the projections defining therebetween a cradle for engaging the anterior vaginal wall and lifting the bladder adjacent the bladder neck.
Claim 7
Dependent Claim
64 words
In an entirely intravaginal urinary incontinence device, the improvement comprising a resilient annular body defining an annulus, the annular body having integrally formed on respective portions thereof two projections that project, at least in part, correspondingly transversely to the annulus of the annular body, the projections defining therebetween a cradle for engaging the anterior vaginal wall and lifting the bladder adjacent the bladder neck.
Claim 8
Dependent Claim
10 words
The device of claim 5 wherein the annulus is planar.
Claim 9
Dependent Claim
19 words
The device of claim 5 wherein the two projections extend exteriorly beyond the exterior periphery of the annular body.
Claim 10
Dependent Claim

The device of claim 5 wherein the two projections extend exteriorly beyond the exterior periphery of the annular body.
Claim 11
Dependent Claim
146 words
In an entirely intra-vaginal device to aid in controlling incontinence in females, the improvement of the device, comprising: a resilient central member having aperture means comprising an aperture through the central member for allowing the discharge of menstrual blood and vaginal secretions through the central member when the central member is in a vagina, the central member being upwardly convex on one side and of cupped configuration on an opposite side at least when the central member is in the vagina; and forward-portion cradle means comprising two, spaced, upward projections from the one side of the central member at one, forward end thereof that form therebetween a cradle depression for engaging one side of an anterior wall of the vagina when the central member is in the vagina and lifting a bladder on an opposite side of the anterior wall adjacent a neck of the bladder.
Claim 12
Dependent Claim
146 words
