Abstract

The invention relates to a neovaginal prosthesis formed by an essentially cylindrical hollow main body comprising a closed upper end and an open lower end, and a securing plate intended to connect to the lower end of the main body.

Claims

1. Neovaginal prosthesis, designed to be temporarily inserted in a vaginal cavity with a determined luminar diameter, comprising a hollow main body which in turn comprises: a closed upper end of essentially rounded geometry, designed to be inserted inside the vaginal cavity, a first orifice defined in the upper end to allow the drainage of liquids and secretions towards the hollow inside of the main body, an upper intermediate cylindrical section located below the closed upper end, a lower intermediate section located below the upper intermediate cylindrical section that has a progressively decreasing diameter, an open lower end, located below the lower intermediate section designed to remain on the outside of the vaginal cavity, protruding slightly from the vaginal opening, a side notch defined in the proximity of the lower end the lower intermediate section to facilitate the coupling of the neovaginal prosthesis in the proximity of the urethra without pressing on it, a second orifice defined in the lower end designed to allow the drainage of liquids from the hollow interior of the main body towards the outside, a securing element designed to be connected to the lower end of the main body which is fitted with a securing plate provided with a plurality of through-openings designed to be traversed by additional securing means, and a hollow protuberance extending from the securing plate designed to be concentrically inserted inside the second orifice of the main body to evacuate liquids towards the outside.

2. (canceled)

3. (canceled)

4. The neovaginal prosthesis of claim 1, wherein it additionally comprises a mesh designed to cover the main body to facilitate the epithelialization of the cavity around it.

5. The neovaginal prosthesis of claim 1, wherein it additionally comprises a third orifice defined in the lower end designed to house an extraction thread to facilitate the extraction of the prosthesis.

PREFERRED EMBODIMENT OF THE INVENTION

[0018] A detailed explanation of the example of preferred embodiment of the object of the present invention is provided below, with the aid of the aforementioned figures.

[0019] The neovaginal prosthesis disclosed is formed by an essentially cylindrical hollow main body (1) which comprises a closed upper end (2) and an open lower end (3), and a securing plate (4) designed to be connected to the lower end (3) of the main body (1), as shown in FIG. 1.

[0020] The main body (1) is designed to be temporarily inserted in a space defined between the bladder and the rectum of a patient with vaginal agenesis by means of the McIndoe surgical technique, to create a vaginal cavity or neovagina with a suitable luminar diameter by means of dilatation. To do this, the upper end (2) has an essentially rounded geometry in the centre whereof a first orifice (5) is defined, to allow the drainage of liquids and secretions through the hollow interior of the main body (1).

[0021] The main body (1) additionally comprises a side notch (6) defined in the proximity of its lower end (3) to facilitate the coupling of the prosthesis in the proximity of the urethra without pressing on it. A second orifice (7) is defined in the centre of the lower end (3), shown in FIG. 3, firstly designed to allow the drainage of liquids from the hollow interior of the main body (1) and in second place to provide the connection of the securing plate (4) with said main body (1). It additionally anticipates the definition of a third orifice (8) designed to house an extraction thread (9) to facilitate the extraction of the prosthesis.

[0022] The securing plate (4), shown in FIG. 2, is designed to be perpendicularly connected to the lower end (3) of the main body (1) to allow its anatomical securing to the patient's body through tapes, not represented in the attached figures, designed to be knotted round the waist.

[0023] To do this, said securing plate (4) comprises a hollow protuberance (10) which is projected from its geometric centre, with a geometry and dimensions such that they facilitate its concentric insertion inside the second orifice (7) of the main body (1) in turn allowing the evacuation of liquids towards the outside. Additionally, a plurality of through-openings (11) defined in the securing plate (4) are designed to be traversed by the aforementioned securing tapes.

[0024] It additionally contemplates the incorporation of a mesh (12) designed to cover the main body (1) of the prosthesis as shown in FIG. 4 and replace in that way the skin graft that is normally performed in the aforementioned technique. To do this, said mesh (12) is made in a biocompatible and biodegradable material which acts as base for the biological generation of tissues, also known as epithelialization, around it and to avoid the adherence of the prosthesis to the surrounding tissues during its surgical insertion. In this case, the securing plate (4) has the additional function of maintaining in vertical position, as shown in FIG. 4, on a surgical table to proceed with its coating with a mesh (12) before its insertion.
