Abstract

Connector and methods for attachment to hollow anatomical structures. The connector consists of an annular rigid body and multiple holding members affixed along its opening. The opening and the inner surface and of the annular body correspond respectively to the opening and the external surface of a hollow anatomical structure. The holding members are deformed by an applied force in a manner that the deformed holding members protrude into the opening of the hollow structure and press it towards the annular rigid body, thus attaching the connector to the hollow anatomical structure. Various embodiments of connectors and methods are provided for attaching the connectors to hollow anatomical structures with different external surfaces.

Claims

1. A method for attaching a connector, comprising an annular rigid body and multiple holding members affixed to said annular body along its opening, to a hollow anatomical structure having an opening, said method comprising the steps of:

(a) selecting a connector with an opening of said annular body that corresponds to said opening of said anatomical structure;

(b) adjoining said connector to said anatomical structure in a manner that said opening of said annular body is aligned with said opening of said anatomical structure; and

(c) deforming said holding members of said connector in a manner that the deformed holding members protrude into said opening of said anatomical structure and press said anatomical structure towards said annular body of said connector.

2. The method for attaching a connector of claim 1, wherein said connector comprises an inner surface of said annular body that conforms to an external surface surrounding said opening of said anatomical structure and said step of adjoining includes aligning said inner surface of said annular body with said external surface of said anatomical structure without deforming said anatomical structure.

3. The method for attaching a connector of claim 2, wherein said connector comprises means for coupling the attached connector to another connector of another hollow conduit system.

4. The method for attaching a connector of claim 3, wherein said inner surface of said annular body comprises microporous structure and said method for attaching includes the step of adhering of said anatomical structure to said connector by a natural growth of connective body tissue of said external surface of said anatomical structure into said microporous structure of said inner surface of said annular body of said connector.

5. A method of attaching a rigid connector to a hollow anatomical structure for the purpose of joining two hollow structures without deforming them by a pair of coupling connectors attached to them, said method comprising the steps of:

(a) providing a rigid connector comprising an annular body with an inner surface conforming to an external surface surrounding an opening of a hollow anatomical structure and multiple holding members affixed to said inner surface of said annular body;

(b) positioning said connector over said hollow anatomical structure so said annular body is aligned with said opening of said anatomical structure and said inner surface of said annular body is adjoined to said external surface of said anatomical structure without deforming said anatomical structure; and

(c) affixing said connector to said anatomical structure by deforming said holding members so the deformed holding members press said hollow anatomical structure towards said annular body.

6. The method of attaching a connector of claim 5, wherein said connector comprises means for coupling the attached connector to another connector of another hollow structure.

7. The method of attaching a connector of claim 6, wherein said inner surface of said annular body further comprises microporous structure and said step of affixing includes adhering of said anatomical structure to said connector by a natural growth of a connective body tissue of said external surface of said anatomical structure into said microporous structure of said inner surface of said annular body of said connector.

8. A method of joining two hollow anatomical structures without deforming them by a pair of connectors attached to them, said method comprising the steps of:

(a) providing a pair of first and second connectors equipped with means for coupling, said first connector comprising an annular body with an inner surface conforming to an external surface surrounding an opening of a first hollow anatomical structure, and multiple holding members affixed to said inner surface of said annular body of said first connector, said second connector comprising an annular body with an inner surface conforming to an external surface surrounding an opening of a second anatomical structure, and multiple holding members affixed to said inner surface of said annular body of said second connector;

(a) attaching said first connector to said first anatomical structure by adjoining said first connector to said first anatomical structure and by deforming said holding members of said first connector so the deformed holding members press said first anatomical structure towards said annular body of said first connector;

(b) attaching said second connector to said second anatomical structure by adjoining said second connector to said second anatomical structure and by deforming said holding members of said second connector so the deformed holding members press said second anatomical structure towards said annular body of said second connector; and

(c) joining the two anatomical structures by coupling the two connectors attached to them.

9. The method of joining two hollow anatomical structures of claim 8, wherein the inner surfaces of the annular bodies of the two connectors comprise microporous structures and said attaching steps include adhering of the connectors to the anatomical structures by growth of connective tissues of the external surfaces of the anatomical structures into the microporous structures of the inner surfaces of the connectors.

10. The method of joining two hollow anatomical structures of claim 9, wherein said step of joining includes exact approximation of a cut edge of said opening of said first anatomical structure with a cut edge of said opening of said second anatomical structure.

11. The method of joining two hollow anatomical structures of claim 10, wherein said method further includes the step of natural healing of the approximated cut edges of the two anatomical structures in a layer specific manner.

12. A pair of two rigid connectors for joining two hollow anatomical structures without deforming them, each connector of said pair comprising:

(a) an annular body forming an opening that corresponds to an opening of a hollow anatomical structure, said annular body with a microporous inner surface conforming to an external surface surrounding said opening of said hollow anatomical structure so said inner surface can be adjoined to said external surface without deforming said anatomical structure;

(b) a plurality of holding members affixed to said inner surface along said opening of said annular body, said holding members capable of being deformed in a manner that the deformed holding members press said hollow anatomical structure towards said annular body; and

(c) means for coupling with the other connector of said pair.

13. The pair of connectors according to claim 12, wherein said holding members are made of thin metal wires.

14. The pair of connectors according to claim 13, wherein said microporous inner surface comprises a layer of fabric.

15. A pair of two rigid connectors for joining two hollow anatomical structures without deforming them, each connector of said pair comprising:

(a) an annular rigid body with an inner surface conforming to an external surface surrounding an opening of a hollow anatomical structure so said inner surface can be adjoined to said external surface without deforming said anatomical structure;

(b) a plurality of holding members affixed to said inner surface of said annular body, said holding members capable of being deformed in a manner that the deformed holding members press said hollow anatomical structure towards said annular body, and

(c) means for coupling with the other connector of said pair.

16. The pair of two connectors according to claim 15, wherein said holding members are made of thin metal wires.

17. The pair of two connectors according to claim 16, wherein said inner surface of said annular body has a microporous structure.

18. The pair of two connectors according to claim 17, wherein said microporous structure comprises a layer of fabric.

19. An anastomosing device for joining two hollow anatomical structures without deforming them, said anastomosing device comprising:
