Abstract

An intra-vaginal device to aid in controlling urinary incontinence, said device including a body with a forward portion to engage the anterior vaginal wall adjacent the bladder neck, which forward portion is expandable to close the bladder neck.

Claims

1. An entirely intra-vaginal device, comprising two opposed limbs interconnected by a flexible base portion so as to be of an upwardly convex generally "U-shaped" configuration, one of the limbs being adapted to lie adjacent the anterior vaginal wall and including a cradle-like structure to lift the bladder base and bladder neck, lying behind the vaginal wall, without closing the urethra, the other limb being adapted to lie adjacent the posterior vaginal wall, and the base portion having an aperture which, in use, is adjacent the cervix of the uterus.

2. The device of claim 1 wherein the device is formed of a resilient material.

3. The device of claim 1 wherein said cradle-like structure is formed by two protrusions extending from the free end of the limb which lies adjacent the anterior vaginal wall.

4. The device of claim 3 wherein the protrusions have a depression therebetween.

5. The device of claim 4 wherein the base portion biases the limbs outwardly to aid in retaining the device within the vagina.

6. The device of claim 1 wherein the limb to lie adjacent the posterior vaginal wall has two legs at its free end, with the legs being curved and splayed so that in use the legs fit over the perineal body for supporting the device in the vagina.

7. The device of claim 1 wherein the limb which engages the anterior vaginal wall is provided with an expandable member to at least partly close the bladder neck.

8. An entirely intra-vaginal device, comprising:

a first limb for being supported only on an interior surface portion of a posterior vaginal wall;

a second limb;

a flexible base portion connecting the first and second limbs to form the limbs and base portion into a generally U-shaped configuration, the base portion having an aperture positioned for being adjacent a cervix of a uterus when the first limb is supported on the interior surface portion of the posterior vaginal wall; and

a cradle-like structure on the second limb for engaging an interior surface portion of an anterior vaginal wall when the first limb is supported on the interior surface portion of the posterior vaginal wall and supporting a base and neck of a bladder located at an exterior surface portion of the anterior vaginal wall opposite the interior surface portion of the anterior vaginal wall without closing a urethra connected to the bladder.

9. An entirely intra-vaginal device having an anterior portion to engage the anterior vaginal wall and a posterior portion to engage the posterior vaginal wall, said device being of a generally arcuate configuration so as to be upwardly convex and being formed of a resilient material so that in use it may be resiliently deformed and therefore bias the anterior and posterior portions into contact with the vaginal wall to retain the device in position within the vagina, and wherein said anterior portion has a cradle which in use lifts the bladder and bladder neck, without closing the urethra, lying behind the anterior vaginal wall.

10. The device of claim 9 having a central body portion extending between the anterior and posterior portions, which central body portion has an aperture to be positioned adjacent the cervix.

11. The device of claim 9 wherein said cradle is provided by a pair of transversely spaced projections between which there is defined a depression through which, in use, the bladder neck passes to the cradle by the projections.

12. The device of claim 11 wherein said posterior portion has a pair of rearwardly projecting legs which in use fit over the perineal body for supporting the device in the vagina.
