Description

Closing device for a blood vessel or the like

The invention relates to a device for plugging a surgically applied or other unnatural opening in a wall of a fluid-containing organ, such as blood vessel, gallbladder and the like, in a living organism.

In surgery it often occurs that an opening has to be made surgically or through a puncture through the skin in a blood vessel or other organ in, for example, a human body, which must then be closed again. This is particularly problematic in blood vessels such as arteries, because manual pressure must be applied to the opening for a long time before sufficient closing tissue has been formed naturally by clotting the blood to close the hole. Since blood thinners are often used, this clotting process is poor and bruising occurs frequently. Sometimes surgery is also required. This leads to a long-term aftercare, which is not in proportion to the actual intervention, such as, for example, doping or the like.

It is known to close the blood vessel and the tissue above it by means of a plug of blood-curdling and swelling material. The problem that arises here is the precise placement of the plug relative to the wall of the liquid vessel. It is inadmissible in particular with blood vessels that plug material enters the blood vessel, which can lead to blockages. However, if the clot remains too far from the blood vessel wall after placement, blood loss will inevitably occur.

The object of the invention is to provide an auxiliary device with which the placement of the plug can be done accurately, so that the opening can be closed effectively.

The device according to the invention is distinguished by an elongated, hollow, flexible holder, at the free end of which a spreadable element is fixedly arranged, and an operating member communicating with the spreadable element for bringing the spreading position from a stretched position to a spread position. element and vice versa.

With the elongated container and the expandable element at the end thereof, it is possible, using the flexibility of the container, to insert the free end with the expandable element into the member through the opening. After spreading the element by means of the operating member, the holder can be retracted again, the spread element hooking behind the opening against the inner wall of the member, i.e. the blood vessel. Afterwards, the surgeon can place a plug of suitable material along the flexible holder and press it until it meets the spread element of the device. The spread element is then brought back into the stretched state and pulled out of the opening. The swellable plug expands and closes the opening in the wall of the blood vessel or organ since the side of the plug facing the organ is precisely positioned.

According to a first embodiment, the element in the form of an inflatable balloon is attached to the elongated hollow container, the operating member being a pump communicating with the balloon via the hollow container. In this embodiment, the spreading of the element is accomplished by inflating the balloon, so that the outside of the balloon comes to rest against the inner wall of the member after the container is withdrawn. After securing the plug, the pressure can be released from the balloon and the balloon can be relaxed so that it can be easily withdrawn from the organ along the plug. Optionally, a vacuum can be applied to the balloon to further facilitate retraction.

According to another embodiment of the invention, the element is designed as a number of strips lying in line with the elongated holder, one end of which is attached to the end of the holder and the other ends to a common coupling piece, which coupling piece is designed with a pulling member which is passed through the hollow container.

The strips have a certain flexibility and stiffness, so that in an unstressed position they will extend in line with the holder. In this state, the element strips and the holder can be passed through the wall of the member, after which a pulling force is exerted on the pulling member. This causes a curvature of the strips and, therefore, a spread thereof, so that the holder can be retracted again, the outer sides of the strips being placed against the inner wall of the member. Thus, the plug can be accurately positioned against the strips, that is, against the wall of the member.

By removing the pulling force on the pulling member, the strips will stretch again, after which the holder can be retracted with the element.

The above and other features of the device according to the invention will be explained in more detail below with reference to a figure description of two exemplary embodiments. In the drawing: Fig. 1 shows a longitudinal section of a blood vessel, prayer in surrounding tissue, in which blood vessel a sleeve is arranged for operative purpose, using a balloon device according to the invention, Fig. 2, 3, 4, 5 and 6 successive stages of the placement of the device according to the invention and the eventual closing of the opening, fig. 7 and 8 a cross-section of a blood vessel corresponding to fig. 1 and 2, wherein as device for closing the opening a strip-shaped container is used.

The device as shown in Figs. 1 to 6 consists of an elongated, flexible holder 1, at the free end of which a spreadable element in the form of a balloon 2 is attached. In the figures, only the end of the container is shown, assuming that the flexible container 1 extends further than shown and is sufficiently long to reach the organ in the living organism from the outside. The other end of the container is connected to a pressure pump 3, for example a manually operated pressure bladder, which communicates with the cavity in the container 1 and therefore with the inside of the balloon 2.

In Fig. 1, a so-called operative sleeve 4 is shown, which has been pre-inserted into the blood vessel V of the tissue W for, for example, introducing operative elements into the blood vessel, such as, for example, a dotter balloon. To this end, a guide wire 5 can already be passed through sleeve 4, which can also be used for inserting the container with balloon 2. This is not necessary and the wire 5 can also be removed beforehand. The introduction of the balloon 2 with the holder 1 through the sleeve 4 is preferred because of its easy introduction. If the container 1 with balloon 2 has been introduced, the balloon 2 can be inflated by means of the pump 3, as shown in fig. 2. It is noted that the balloon here substantially closes the passage of the blood vessel V, but by an appropriate size may also leave enough space for normal blood flow.

Subsequently, the sleeve 4 is retracted in the direction of the arrow P2 and after the retraction of the container 1 the balloon will also come to lie in the direction of the arrow P2 with the outer wall against the inner wall of the blood vessel V, see fig. 3 and 4. Subsequently, a plug P can be placed in the tissue W next to or around the holder 1, which plug is of suitable material, for instance swellable during moisture absorption and provided with blood-clotting agents.

The plug P is introduced into the tissue W until the bottom O thereof contacts the outside of the inflated balloon 2. This leads to an accurate position of the plug P relative to the wall part of the blood vessel V, so that no plug material P enters the blood vessel V.

By releasing the pressure from the balloon 2, the balloon will return to the stretched position as shown in Fig. 5 and the container with the balloon can be withdrawn from the blood vessel V in the direction of the arrow P2. Finally, the plug P will fill the opening caused by the container 1 and thus the blood vessel V is completely closed.

Thanks to this procedure it is now possible to effectively close the opening therein without much pressure on the blood vessel wall V. Blood loss is hereby prevented and any aftercare for bruising can be avoided.

Figures 7 and 8 show a second embodiment of the device according to the invention. The holder 1 is here provided with a number of strips 7, which is connected at the top end 8 to the end of the holder 1, and the bottom end 9 of which is coupled to a common coupling piece 10. The common coupling piece 10 is connected to a pulling element 11 , which is guided through the holder 1 and is coupled outside the holder 1 to a pulling means (not shown), for example eye.

By attracting the pulling element 11 in the direction of the arrow P3, the coupling piece 10 is moved towards the end 8, whereby the strips 7 will curve in a spherical shape and be spread apart. Due to a sufficient curvature along the dotted line 12, the outside of the strips 7 will come into contact with the inner wall of the blood vessel V, after which the plug material P can be applied against the strips 7. In the same manner as described above, the position P is thus accurately determined. and after releasing the pulling element 11, the holder 1 with the element strips 7, which have taken up the position according to Fig. 7, can be withdrawn from the member or tissue. The plug will then close the opening as a result of the holder 1 and assume the position in Fig. 6. The invention is not limited to the above-described embodiments.

It will be clear that with the device according to the invention no foreign material remains in the organ or blood vessel, so that no danger of blockage or damage will occur in the organ.
