Abstract

Parabolic pessary characterized in that it is composed of a ring-shaped component (1) that is open in a lunette shape or closed in a ring shape, with a raised distal posterior part (4) of cube shape or flat shape, having the role of supporting the uterus and two lateral branches (5, 5) that are thinner than the distal part (4), and a proximal anterior part (6) that is positioned at the median part of the feminine urethra, this ring-shaped component (1) having an upper face (2) with a paraboloid shape that adapts to the pelvic paraboloid, and a posterior face (3) having the shape of a more-open paraboloid having, at its median part, a thicker part (8) allowing it to bear on the pelvic floor.

Claims

1. Parabolic pessary intended to be positioned in the vagina of a patient, to maintain the organs of the pelvic cavity, particularly the uterus and the vagina in position above the pelvic floor, and correct urinary incontinence from effort. characterized in that it is composed of a ring-shaped component that is open in a lunette eyeglasses shape or closed in a ring shape, made of a supple anallergic biocompatible material (1) with a raised distal posterior part (4) of cube shape (or flat shape), having the role of supporting the uterus and two lateral branches (5, 5) that are thinner than the distal part (4), and a proximal anterior part (6), with this ring-shaped or opened eyeglasses shape component (1) having an upper face (2) with a paraboloid shape that adapts to the pelvic paraboloid, and a posterior face (3) having the shape of a more-open paraboloid having, at its (median) posterior part, a thicker part (8) allowing it to bear on the pelvic floor.

Description

[0051] The characteristics of the parabolic pessary that is the subject of the invention will be described in greater detail, with reference to the appended non-limitative drawings, in which:

[0052] FIG. 1 is a top view of the upper face of the pessary; the dotted lines represent a configuration variant;

[0053] FIG. 2 is a profile cross-section of the pessary, according to axis II-II of FIG. 1;

[0054] FIG. 3 is a parasagital profile cross-section of the pessary illustrated in FIG. 1;

[0055] FIG. 4 is a diagram illustrating the parabolic pessary positioned in the pelvic cavity.

[0056] In the illustrations, the parabolic pessary is a ring-shaped component that is open or closed at the front, as a monoculmar eyeglasses having an upper face 2 and a posterior face 3.

[0057] According to FIG. 1, the ring-shaped component that is open or closed at the front, 1, has a raised distal posterior part, 4, of cube shape or flat, such as illustrated in FIG. 2, together with two lateral branches, 5, 5, that are thinner than the distal part, 4, and arepossiblyclosed by a proximal anterior part, 6.

[0058] It should be noted that the central aperture, 7, of the ring-shaped component, 1, can be closed by a membrane not having been illustrated, that has the role of forming an anti-conceptual barrier.

[0059] According to FIG. 4, the raised distal posterior part, 4, of cube shape, is positioned under the uterus, U, which it has the role of supporting.

[0060] According to FIGS. 2 and 4, the upper face, 2, of the ring-shaped component, 1, has a paraboloidal shape that adapts to the pelvic paraboloid defined by the sacrum, S, and the pelvic floor, PE, so as to extend it and direct the reflected abdominal pressure upwards and towards the front of the abdomen, namely the anterior abdominal wall and the osseous pubis.

[0061] According to FIG. 2, the posterior face, 3, of the ring-shaped component, 1, is of more-open paraboloid shape, and its median part has a greater thickness, 8, allowing it to bear on the pelvic floor, PE, such as illustrated in FIG. 4.

[0062] In a manner not illustrated in the Figures, a vibrating motor can be inserted into the pessary at this thicker part.

[0063] According to FIGS. 1 to 4, the upper face, 2, of the ring-shaped component, 1, hasat its proximal extremitya thicker part forming a button, 9, that has the function of bearing on either side of the urethra, UR.

[0064] According to the example of implementation illustrated in FIG. 1, this button has two parts, 9, 9, having the role of bearing either side of the urethra, to enable maintenance of this angle and the urethral zig-zag.

[0065] According to FIG. 2, the ring-shaped component, 1, hason averagea height (h) of approximately 20 to 40 mm and a width (1) of around 25 to 50 mm. In addition, the distal posterior part, 4, is raised in relation to the thicker part forming button, 9, by a height (h1) of approximately 20 to 30 mm.

[0066] It should be noted that the essential characteristics of the parabolic pessary addressed by the invention are in connection with the heightening in cube shape or flat shape of the distal posterior part, 4, with the paraboloidal shape of the upper face, 2, and the posterior face, 3, and the presence of the sub- or para-urethral thicker part forming a button, 9, 9, closed ring or open, eyeglasses like.

[0067] However, the proximal anterior part, 6, can be relatively narrow, such as illustrated by the solid lines in FIG. 1, or wider, such as illustrated by dotted lines in the said FIG. 1, without this falling outside the scope of the invention.
