Abstract
An anastomosis device (11) for use in coupling two ends of tubular stumps (13). The device comprises two hollow tubular members (21), adapted to be placed over said tubular stumps. The hollow tubular members are further capable of radially expanding from a first inner diameter to a second, larger inner diameter. Each hollow tubular member, while having the first inner diameter, being further adapted to allow everting of the stump proximal end over the tubular member proximal end. The device further comprises an elastic sleeve (31), adapted to be put on said tubular member proximal ends with the everted ends of said stumps, the sleeve further being adaptable to maintain said everted ends in a predetermined distance.
Claims25
A device for anastomosis of a first and a second tubular stumps, each having a stump proximal end, and further having a shrunk outer diameter in its shrunk state and an expanded outer diameter in its expanded state, the device comprises:
- a first and a second hollow tubular members, adapted to be placed over said first and second stumps, respectively, each having a tubular member proximal end, a tubular member middle section, a first inner diameter, which is at least equal to said shrunk outer diameter, a second inner diameter, which is at least equal to said expanded outer diameter, and a length greater than said second inner diameter, the tubular members further being capable of radially expanding from said first inner diameter to said second inner diameter, each tubular member, while having the first inner diameter, being further adapted to allow everting of the stump proximal end over the tubular member proximal end;
- and
- an elastic sleeve having two sleeve ends, adapted to be put on said tubular member proximal ends with the everted ends of said stumps, the sleeve further being adaptable to maintain said everted ends in a predetermined distance.

A hollow tubular member adapted to be placed over a stump having a stump proximal end, a shrunk outer diameter in its shrunk state and an expanded outer diameter in its expanded state, the tubular member comprises a tubular member proximal end, a tubular member middle section, and having a first inner diameter, which is at least equal to said shrunk outer diameter, a second inner diameter, which is at least equal to said expanded outer diameter, and a length greater than said second inner diameter, the tubular members further being capable of radially expanding from said first inner diameter to said second inner diameter, each tubular member, while having the first inner diameter, being further adapted to allow everting of the stump proximal end over the tubular member proximal end.
A method of performing an anastomosis of a first and a second tubular stumps, each having a stump proximal end, and further having a shrunk outer diameter in its shrunk state and an expanded outer diameter in its expanded state, the method comprising:
- providing a device comprising a first and a second hollow tubular members, each having a tubular member proximal end, a tubular member middle section, a first inner diameter, which is at least equal to said shrunk outer diameter, a second inner diameter, which is at least equal to said expanded outer diameter, and a length greater than said second inner diameter, said tubular members further being capable of radially expanding from said first inner diameter to said second inner diameter;
- and an elastic sleeve having two sleeve ends;
- determining first inner diameter of the tubular members;
- placing the first tubular member over the first stump, while it is in its shrunk state;
- placing the second tubular member over the second stump, while it is in its shrunk state;
- everting the proximal ends of the first and second stumps over the proximal ends of the first and second tubular members, respectively;
- putting the sleeve ends on the corresponding proximal ends of the tubular members with the everted proximal ends of the stumps;
- and
- maintaining the everted proximal ends of the stumps in a predetermined distance from each other.
