Abstract

This disclosure relates to a vascular connector device which has features that permit the connector device to close a vascular duct and to subsequently permit the vascular duct to be re-opened, if desired. The vascular connector of this disclosure features a tubular shaped vascular connector having a guillotine type plunger arrangement or assembly which can be actuated for first closing and then re-opening the vascular duct, if desired. Also disclosed are two separate clamp mechanisms in the form of special tongs with one used for initially actuating the guillotine type plunger arrangement to close off the vascular duct and the other clamp mechanism is used for achieving opening of the vascular duct by moving the guillotine type plunger arrangement into another position which causes the vascular duct to re-open by means of the restoration of an open conduit through the vascular duct because of the alignment of both previously separated portions of the vascular duct with an aperture in the guillotine type plunger mechanism.

Claims

1. A method for effecting vascular duct closures comprising the steps of:

closing a vascular connector around a portion of a vascular duct, and actuating a guillotine type plunger assembly within the vascular connector to both cut off a portion of the portion of a vascular duct and block off and hold connected the severed ends of the vascular duct portion, wherein said guillotine type plunger assembly comprising a piston type member having an extension member connected to one end of said piston type member, said piston type member having an opening extending therethrough in the same direction as said channel means, a hollow fibrous member located in said opening, and a hollow short tubular portion.

2. A method for effecting vascular duct closure and subsequent re-opening of said vascular duct comprising the steps of:

closing a vascular connector around a portion of a vascular duct;

actuating a guillotine type plunger assembly to one position within said vascular connector to both cut off a portion of said portion of a vascular duct and block off the severed ends of said vascular duct portion; and

subsequently actuating said guillotine type plunger assembly to another position within said vascular connector to re-open the previously severed and blocked off ends of said vascular duct portion.

3. A method in accordance with claim 2 wherein said guillotine type plunger assembly comprising a piston type member having an extension member connected to one end of said piston type member, said piston type member having an opening extending therethrough in the same direction as said channel means, a hollow fibrous member located in said opening, and a hollow short tubular portion.

4. A method in accordance with claim 3 wherein said extension member blocking said vascular duct in said one position of said guillotine type plunger assembly.

5. A method in accordance with claim 4 wherein said opening in said piston type member communicating with said previously severed ends of said vascular duct portion in said another position of said guillotine type plunger assembly.

6. A vascular connector for effecting vascular duct closure and permitting vascular re-opening comprising, in combination, an upper portion and a lower portion, channel means located in at least one of said upper and lower portions for holding a portion of a vascular duct, and guillotine type assembly means movably mounted across said channel means for both removing a portion of said portion of the vascular duct and blocking off said channel means in one position thereof and for unblocking said channel means in another position thereof, wherein said guillotine type assembly means comprising a piston type member having an extension member connected to one end of said piston type member, said piston type member having an opening extending therethrough in the same direction as said channel means, a hollow fibrous member located in said opening, and a hollow short tubular portion.

7. A vascular connector in accordance with claim 6, including fastening means for connecting the non-pivoting ends of said upper and lower portions, said fastening means comprising a male connector portion connected to one of said upper and lower portions and a female connector portion connected to the other of said upper and lower portions, including prong means located in said channel means for gripping and holding said portion of said vascular duct.

8. A vascular connector in accordance with claim 6 wherein said piston type member and said extension member being located in one of said upper and lower portions, said hollow short tubular portion being located in the other of said upper and lower portions.

9. A vascular connector in accordance with claim 8 wherein said hollow short tubular portion having cutting means located at one end thereof adjacent said extension member for cooperation with said extension member in cutting off a portion of said portion of a vascular duct.

11. A vascular connector in accordance with claim 8 wherein said hollow short tubular portion having an outer diameter being substantially equal to the outer diameter of said piston type member.

12. A vascular connector in accordance with claim 11 wherein said cutting means being circular, said hollow short tubular portion having cutting means located at one end thereof adjacent said extension member for cooperation with said extension member in cutting off a portion of said portion of a vascular duct, the outer diameter of said extension member being greater than the diameter of said cutting means.

10. A vascular connector for effecting vascular duct closure and permitting vascular re-opening comprising, in combination, an upper portion and a lower portion, channel means located in at least one of said upper and lower portions for holding a portion of a vascular duct, and guillotine type assembly means movably mounted across said channel means for both removing a portion of said portion of the vascular duct and blocking off said channel means in one position thereof and for unblocking said channel means in another position thereof, including an opening extending transversely across and through both said upper portion and said lower portion, said guillotine type assembly means movably mounted within said opening, wherein said guillotine type assembly means comprising a piston type member having an extension member connected to one end of said piston type member, said piston type member having an opening extending therethrough in the same direction as said channel means, a hollow fibrous member located in said opening, and a hollow short tubular portion, including fastening means for connecting the non-pivoting ends of said upper and lower portions, said fastening means comprising a male connector portion connected to one of said upper and lower portions and a female connector portion connected to the other of said upper and lower portions, and including prong means located in said channel means for gripping and holding said portion of said vascular duct.
