Abstract

Suturing elements for connecting a vascular prosthesis to a blood vessel include an internal, substantially annular body intended to be received in the blood vessel in addition to an external annular body intended to lie clampingly on an outer wall of the blood vessel at least practically at the location of the internal annular body. At least one of the two annular bodies is provided with suturing members which grip in the vessel wall so as to effect an adequate fixation of at least the internal annular body. The device for use with such suturing elements and a vascular prosthesis which is provided on at least one of its outer ends with at least a part of such suturing elements are disclosed. Different embodiments of such prostheses together form a modular vascular prosthesis system. A side vessel of a thus supported blood vessel can be preserved using branch elements.

Claims

1. Branch means for connecting a side vessel of a main blood vessel to a vascular prosthesis arranged in the main blood vessel, comprising a flange-shaped internal body intended to lie against an inner wall of the vascular prosthesis, which flange-shaped body carries on its side directed toward the vascular prosthesis a hollow stem open on both sides as well as at least one suturing member, both of which are able to penetrate through the wall of the vascular prosthesis, and comprising a flange-shaped external body intended to lie round the side vessel against an outer wall of the main blood vessel at the position of the internal body, which external body is provided with a bore for receiving the side vessel and the stem therein, wherein at least in mutually connected state the suturing member is received in the external flange-shaped body, thus forming a firm mutual connection, and the stem is received in the side vessel, thus forming an open connection between the main blood vessel and the side vessel.

2. Branch means as claimed in claim 1, characterized in that the stem tapers to a point at its free end.

3. Branch means as claimed in claim 1, characterized in that the external disc-like body comprises a channel which provides access to the bore from a peripheral edge.

4. Branch means as claimed in claim 1, characterized in that the internal body is manufactured from metal and the external body comprises a plastic.

5. Device for inserting and suturing a flexible tubular vascular prosthesis in the body, which prosthesis is provided on a free end with an annular body which lies against a wall thereof, comprising a flexible infeed line, which infeed line is provided on one end with a fixation member intended for receiving thereon the vascular prosthesis with the internal annular body, which fixation member is able when energized to exert a radially outward directed force on the annular element.

6. Device as claimed in claim 5, characterized in that the annular body comprises a metal ring with suturing members which can be pressed radially outward and that the fixation member is able to exert a radially outward directed force on at least the suturing members of the annular body.

7. Device as claimed in claim 6, characterized in that the suturing members comprise lips with sharp ends which are retracted and can be pressed radially outward and that the fixation member comprises a rotatable disc for receiving the annular body thereon, which disc is provided with recesses for receiving the lips of the annular body therein.

8. Device as claimed in claim 7, characterized in that the fixation member comprises two discs which are rotatable in opposing directions and are mutually adjacent and which together receive the annular body thereon, which discs are both provided with recesses for receiving therein lips of the annular body which are retracted in opposing directions and which can be pressed radially outward.

9. Device as claimed in claim 5, characterized in that the fixation member comprises an inflatable body which in a first at least partially evacuated state can be received in the prosthesis with the annular body and in a second filled state takes on a cylindrical shape coaxially with the prosthesis, an external diameter of which is at least practically equal to an internal diameter of the vascular prosthesis.

10. Device as claimed in claim 9, characterized in that in the second state the inflatable body is at least practically non-stretch and maintains an internal pressure in the order of magnitude of several tens of atmospheres.

11. Device as claimed in claim 5, characterized in that the device comprises a second fixation member intended for fixing a second annular body, which second annular body is intended for lying against an outer wall of a blood vessel and that monitoring means are provided for indicating the mutual position of both fixation members.

12. Vascular prosthesis comprising a flexible tubular body intended to be connected to a blood vessel with a first and a second end respectively at a first and a second location, characterized in that the tubular body comprises an opening in a wall thereof between the first and second end.

13. Vascular prosthesis as claimed in claim 12, characterized in that the tubular body comprises an externally directed collar around the opening.
