Description

VALVE FOR ARTIFICIAL BLOOD VESSEL

The present invention relates to artificial valves for blood vessels, that is to say the devices to compensate for the absence or malfunction congenital or acquired natural valves of the vascular system, finding a particularly advantageous application in the veins but also in special cases, in the arteries for example at the output of the heart.

Valves for deficient blood vessels have to date made the object of repair or surgical transplants and structure of the proposed artificial prostheses only allows implantation of these prostheses outside the vessels.

The invention thus aims to achieve an artificial valve that can be implanted directly into the blood vessels without causing problems paπiculiers operators, which is a simple structure and a very low cost.

More specifically, the present invention relates to an artificial valve for vessel through which a blood flow in a preferred direction given, characterized in that it comprises: - an elongate body having a cross section adapted to be growing between its two ends , said elongate body being located in said vessel,

- first means for securing a point of said elongate body with a first point of the inner wall of said vessel so that the end of smaller cross-section of said elongate body is located upstream, in the preferred direction of circulation of said blood flow, by relative to the other end adapted to be larger in section, and

- means for increasing, when the blood flow tends to flow back into said vessel, the value of the projection, substantially along the longitudinal axis of said vessel, of the end section of said elongate body adapted to be the greatest , on a plane substantially perpendicular to said longitudinal axis, until the projection is substantially equal to the cross section of said vessel.

Other features and advantages of the present invention appear from the following description given in the appended drawings of illustration, but not limitation, in which:

Figures 1 and 2 show two views broken away and partly in perspective of a first embodiment of an artificial valve for blood vessel according to the invention respectively in two possible states depending on the direction of blood flow in the vessel, and / PC17FR95 19159/01669

Figures 3 and 4 show two views broken away and partially in perspective a second embodiment of an artificial valve for blood vessel according to the invention respectively in two possible states depending on the direction of blood flow in the vessel. II-is first noted that, although Figures 1 to 4 show two embodiments of an artificial valve for blood vessel according to the invention, to simplify the following description and to facilitate understanding , the same references designate, in these figures, the same means or elements, regardless of the form in which such means or elements have been shown.

In general, the artificial valve according to Figures 1 to 4 for blood vessel through which blood flow in a given preferential direction comprises an oblong body 2 located in the blood vessel 100 and having a cross section adapted to be growing between its two ends 3 and 4. the artificial valve further comprises first means 5 for securing a point 34 of the elongate body 2 with a point 106 of the inner wall 101 of the vessel so that the end 3 of the elongate body 2, from smaller cross section, is located upstream 102 in the preferred direction of flow 103 of the blood flow 104, with respect to the other end 4 which can be of larger section, and means for increasing, when the blood flow 104 tends to flow back, figures 2 and 4, into the vessel 100, the value of the projection, substantially along the longitudinal axis 105 of the vessel, of the section of the end 4 of the elongated body adapted to be most large on a plane 6 substantially perpendicular to the longitudinal axis 105, until the projection is substantially equal to the cross section of said vessel.

With particular reference to Figures 1 and 2, these figures show two views broken away and partly in perspective of a first embodiment of an artificial valve 1 for blood vessel 100 adapted to be traversed by a flow of blood in 104 a preferred direction given 103.

According to this first embodiment, the elongated body 2 having a cross section adapted to be growing between its two ends comprises a casing 21 whose general shape is that of a substantially conical cornet or similar to that shape. As for the means to grow, when the blood flow tends to flow back into the vessel, the value of the projection, substantially along the longitudinal axis 105 of the vessel, of the section of the end 4 of the elongated body adapted to be greater, on a plane substantially perpendicular to this longitudinal axis 6, until the projection is substantially equal to the cross section of the vessel, they are essentially constituted by the fact that the casing 21 is made of a relatively flexible material such as plastics or the like material such as PTFE, polyurethane, etc.

In an advantageous embodiment, it is possible that the artificial valve 1 according to the embodiment illustrated in Figures 1 and 2 further comprises means for maintaining a distance at least two points of the inner wall of the casing 21 so that the opening 22 of the horn, which is the end 4 adapted to have the larger cross-section, always partially open, as shown in Figure 1. These means which have not been specifically illustrated may for example be constituted by resilient means such as leaf springs "V" or the like disposed inside the horn. As for the means 5 for fixing the elongate body 2 in the blood vessel 100 at a point 106 of the inner wall 101 of the vessel so that the end 3 of smaller cross section is located upstream 102 in the preferred direction of movement 103 blood flow 104, with respect to the other end 4 which can be of larger cross section, which may for example be constituted by a seam made with son or similar biocompatible and non-absorbable, e.g. son PTFE connecting the flexible wall of the cone with the wall of the blood vessel.

In this first embodiment according to Figures 1 and 2, the artificial valve 1 may advantageously further comprise second means 7 for securing the elongated body 2 at least a second point 108 of the inner wall 101 of blood vessel, unconfounded with the first point 106 and so that the second point 108 is located on a substantially parallel to the longitudinal axis 105 of the right blood vessel 100 and passing through the first point 106. the implantation of an artificial valve 1 as that illustrated figures 1 and 2 is not difficult for an operator and, when implanted as shown in these two figures, it works as follows:

When blood flow 104 flows in the normal direction 103, the envelope 21 is flattened as shown in Figure 1. The cross section of the elongated body 2 is very low along the body and does not obstruct the flow blood flow. By cons, if, for reasons that are known to those skilled in the art, the flow direction of the blood flow 104 tends to be reversed as shown in Figure 2, it rushes into the envelope by the opening 22 in the end 4 of the elongated body 2, and inflates, this swelling is substantially due to the pressure difference which then exists between the upstream and downstream defined under normal blood flow .

As in the case of the blood reflux, the opening 22 of the horn has a projection, substantially along the longitudinal axis 105 of the vessel, on a plane 6 substantially perpendicular to the longitudinal axis 105, substantially equal to the cross section of the vessel blood, it marries almost completely the inner wall of the vessel and inflated casing thus prevents blood flow in the opposite direction to the normal direction 103.

In the example illustrated Figure 2, the position of the opening 22 when the envelope is inflated by a blood reflux is defined so as to be substantially perpendicular to the axis 105 of the vessel. In this case, the value of its projection as defined above is substantially equal to its effective area.

For the artificial valve allows to obtain the desired result, it is necessary that the blood reflux rushes into the envelope 21 as described above. This requires that, for safety, the opening 22 of this envelope is never completely closed. The spring means defined above allows the opening to be always partially open and fully open, or deployed, under the pressure difference between the upstream and downstream defined above, when the flow blood tends to flow in the opposite direction of the preferred direction.

The second means 7 for securing the elongated body 2 at least a second point 108 of the inner wall 101 of blood vessel avoid that the bag turns, that is to say its end 3, normally upstream in the correct direction of blood flow, passes downstream of its end 4 and prevents the normal blood circulation.

Figures 3 and 4 show two views broken away and partly in perspective of a second embodiment of the artificial valve 1 for blood vessel 100 suitable for being traversed by a blood flow 104 in a preferred direction given 103. In this mode of embodiment, the elongated body 2 having a section adapted to be growing between its two ends 3 and 4 is constituted by an envelope whose general shape is that of a solid horn 3 1

Figure imgf000006_0001
ant / PC17FR95 19159/01669

substantially the shape of an oblique cone, the base 32 is a section such that when the blood flow tends to flow back into the vessel, the value of its projection, substantially along the longitudinal axis 105 of the vessel on a map 6 substantially perpendicular to this longitudinal axis, is substantially equal to the cross section of the vessel. The elongate body 2 is fixed to the inner wall 101 of blood vessel 106 at a point of this wall, substantially at its point 34 belonging to the base 32 and the generator 33 of the solid horn 31 which has the smallest length.

In addition, to obtain the results described below, the generator 33 of the solid horn 31 which has the smallest length is preferably greater than the diameter of the blood vessel.

In this second embodiment of the artificial valve according to Figures 3 and 4, the means 5 for securing the elongate body in the \ blood aisseau 100 to point 106 of the inner wall 101 of the vessel are rotating fastening means. These means may, also, be formed by stitching the binding point 34 of the base 32 of the oblique cone with the point G 1 of the inner wall of the blood vessel by means of a wire biocompatible but non-resorbable, for example with a PTFE wire.

The implantation of an artificial valve such as that illustrated in Figures 3 and 4 present, as above, no difficulties for the operator.

When implanted as shown in Figures 3 and 4, it functions as follows:

When blood flow 104 flows in the preferred direction 103, the solid horn shaped oblique cone assumes a natural position in which it provides to blood flow 104 a lowest pressure drop. This position can be exemplified by that shown in Figure 3.

If the blood flow 104 tends to flow in the direction opposite to the normal direction 103, the pressure difference that exists in this case between the upstream and downstream as defined above for the normal flow, makes pivoting the solid cone around the point 106 and makes it take a position such as that illustrated in Figure 4. as in the case of such flow, the value of the projection of the base 32, substantially along the axis longitudinal 105 of the vessel on a map 6 substantially perpendicular to this longitudinal axis, is substantially equal to the cross section of the vessel, the base 32 of the casing conforms to the interior vessel wall. The envelope then closes almost completely the blood vessel and prevents reflux. In an advantageous embodiment, at least one point of the elongated body 2, for example the attachment point 34 defined above, is further attached by a link 36, for example of PTFE, a 35 point outside the blood vessel and belonging a resistive element. This embodiment has the advantage, if the attachment points would yield, maintain the oblong body in the blood vessel in a particular place and prevent it being driven by the blood flow.

In the first embodiment described above, the means that prevent the envelope to turn, that is to say that prevented its 3'-end, usually upstream in the sense of proper blood flow, to pass in downstream of its end 4, consisted in that the oblong body was attached to the inner wall of the blood vessel in at least two points 106, 108 located on the same generatrix of the vessel. In this second embodiment, these means are simply constituted by the fact that the length of the generatrix 33 of the oblique cone is greater than the diameter of the vessel. In this way, if, under the action of the blood flow in the normal direction 103, the solid cone tends to rotate around the point 106 of a too large amplitude, the 3'-end of the cone abuts against the wall interior 101 of the vessel, preventing the cone from turning, that is to say its end 3 to end up downstream of its end 4 with respect to the normal flow of blood flow 103 104.

It should be noted that, unlike the heart valves, it is not necessary that such artificial blood vessel valve works by providing a perfect seal in the direction to prevent blood reflux. Simply relative sealing eliminating the majority of reflux.

Preferably, in the case where the elongated body 2 is hollow, it even advantageous that the end 3 of smaller cross-section has a small orifice 40 to maintain, inside the elongated body 2 a slight circulation and avoid blood stasis which can cause caillotage or thrombosis.

In the above description, it appears that the artificial valve for blood vessel according to the invention is very advantageous, mainly by its simple structure, reliable operation and ease of implantation inside of a blood vessel by a distance introducer with a catheter.
