Abstract

A urinary probe, shaped to fit into a cavity left after prostate surgery to provide haemostatic compression, consists of an inflatable balloon (2) designed to fit the whole of the cavity. The balloon has proximal and distal elements (1a,1b) and a body (3) between them in the shape of a spinning top. The balloon has a circular shoulder (4) lying orthogonally to its tubular proximal element (1a), after which it tapers and then forms two stepped tubes (6,8) of reducing diameters, connected to the distal tubular element (1b). In between the tubular sections, there are steps (7,9). The probe can be made in a glass mould from a biocompatible polymer material, preferably polyurethane.

Description

SONDE URINAIRE A BALLONNET HEMOSTATIQUE
La présente invention concerne une sonde urinaire vésicale destinée à éviter un des inconvénients post-opératoires principaux de la chirurgie de la prostate, qui est l'hémorragie postopératoire.HEMOSTATIC BALLOON URINARY PROBE
The present invention relates to a bladder urinary catheter intended to avoid one of the main postoperative disadvantages of prostate surgery, which is postoperative hemorrhage.

On connaît de nombreuses sondes urinaires à ballonnet et notamment la sonde urinaire à ballonnet hémostatique, faisant l'objet du brevet français nO 9111646 au nom du Demandeur, qui permet de juguler l'hémorragie de manière satisfaisante au niveau du fond de la loge prostatique, cette loge tres vascularisée ayant la forme d'un coquetier. Numerous balloon urinary catheters are known, and in particular the hemostatic balloon urinary catheter, which is the subject of French patent No. 9111646 in the name of the Applicant, which makes it possible to contain the hemorrhage satisfactorily at the bottom of the prostate gland, this very vascularized lodge having the shape of an egg cup.

Le demandeur a maintenant trouvé que l'on pouvait encore améliorer un tel type de sonde pour qu'elle ait un effet de compression hémostatique renforcée. The applicant has now found that such a type of probe could be further improved so that it has an enhanced hemostatic compression effect.

A cet effet, le ballonnet de la sonde urinaire à ballonnet hémostatique qui garde la forme d'une toupie presente une modification de forme dans sa partie inférieure. To this end, the balloon of the hemostatic balloon urinary catheter which keeps the shape of a top has a shape modification in its lower part.

La présente invention sera mieux comprise par la description qui va suivre d'un mode de réalisation, en référence au dessin annexé, donné à titre illustratif, dans lequel - la figure 1 représente la sonde à ballonnet de l'invention. The present invention will be better understood from the following description of an embodiment, with reference to the appended drawing, given by way of illustration, in which - FIG. 1 represents the balloon probe of the invention.

En référence au dessin, le ballonnet (2) gonflable de manière à épouser la totalité de la paroi de la loge prostatique évidée après opération, depuis le fond de celle-ci jusqu'à sa partie urétrale, comporte deux éléments tubulaires proximal (la) et distal (lb) de diamètre (d) légèrement superieur à celui de la sonde sur laquelle ils viendront se positionner et entre lesquels est située le corps du ballonnet (3). With reference to the drawing, the inflatable balloon (2) so as to conform to the entire wall of the prostatic cavity hollowed out after operation, from the bottom thereof to its urethral part, comprises two proximal tubular elements (la) and distal (lb) of diameter (d) slightly greater than that of the probe on which they will be positioned and between which is located the body of the balloon (3).

Le corps du ballonnet (3) présente presqu'orthogonalement par rapport à l'élément tubulaire proximal (la), un épaulement circulaire (4) d'un diamètre (D) réalisant un renflement (5) en forme de toupie destiné à venir comprimer le fond de la loge prostatique, s'amincissant ensuite progressivement selon une pente (p) suivant les parois de la loge prostatique jusqu'à une partie tubulaire (6) de diamètre (D1) inférieur à (D) et se prolongeant ensuite après un léger décrochement (7) par une partie tubulaire fusiforme (8) de diamètre (D2) inférieur à (D1) destinée à venir se positionner en compression sur la partie urétrale de la loge prostatique, le corps du ballonnet (3) débouchant, apres une nouvelle diminution progressive de diamèmètre (9), dans l'élément tubulaire distal (lb).  The body of the balloon (3) has almost orthogonally relative to the proximal tubular element (la), a circular shoulder (4) of a diameter (D) providing a bulge (5) in the form of a spinning top intended to compress the bottom of the prostate gland, then gradually tapering off at a slope (p) along the walls of the prostate gland to a tubular part (6) of diameter (D1) less than (D) and then extending after a slight detachment (7) by a fusiform tubular part (8) of diameter (D2) less than (D1) intended to be positioned in compression on the urethral part of the prostate gland, the body of the balloon (3) emerging, after a further progressive decrease in diameter (9) in the distal tubular element (lb).

Le ballonnet tel que décrit sera réalisé en matériaux biocompatible souple, notamment en polyuréthane, de préférence par moulage. The balloon as described will be made of flexible biocompatible materials, in particular polyurethane, preferably by molding.

Cette nouvelle conception de sonde à ballonnet, du fait de compression hémostatique renforcée obtenue sur toute la loge prostatique jusqu'à sa partie urétrale, présente de nombreux avantages, à savoir d'éviter l'hémorragie post-operatoire souvent importante, d'éviter par suite le recours à des transfusions sanguines, mais également d'éviter toute infection rétrograde en empêchant toute progression microbienne locale vers la loge prostatique et de là, vers la vessie. This new design of balloon catheter, due to the reinforced hemostatic compression obtained over the entire prostatic compartment to its urethral part, has many advantages, namely to avoid the often significant post-operative hemorrhage, to avoid by following the use of blood transfusions, but also to avoid any retrograde infection by preventing any local microbial progression to the prostate gland and from there to the bladder.

Pour la réalisation d'une telle sonde, il peut être envisagé un moule, de préférence en verre, à partir duquel le ballonnet (2) pourra être fabriqué par exemple par moulage par rotation en bain immergé, d'un polymère biocompatible, notamment d'un polyuréthane.  For the production of such a probe, it is possible to envisage a mold, preferably made of glass, from which the balloon (2) can be produced, for example by rotational molding in a submerged bath, of a biocompatible polymer, in particular d 'a polyurethane.
