Abstract
The invention concerns a device for connection between previously intubed ends of a corporeal duct (12) and a substantially tubular prosthesis (10) characterized in that it consists of a sleeve (16) with meshed structure or the like deformable by means of a balloon catheter and capable of radial expansion between a stable configuration of minimum diameter and a final configuration after expansion likewise stable, said sleeve (16) comprising, at each end, a series of teeth (22) for transfixing overlapping parts of the sleeve, uniformly aligned in a ring formation and radially oriented, said teeth (22) having a hemostatic profile including a base part (32) with circular cross-section extended by a trihedral terminal portion (34).

1-9. (canceled)
A device for connecting previously intubed ends of a body duct and a prosthesis having an essentially tubular shape, the device comprising:
- a mesh sleeve deformable by use of a balloon catheter and capable of radial expansion between a stable minimal-diameter configuration and a final after-expansion configuration that is also stable, the sleeve comprising a series of fixation barbs on each end adapted to engage a portion of the prosthesis, a portion of the body duct, or a combination thereof surrounding the sleeve, the fixation barbs aligned at regular intervals and radially encircling the sleeve,
- wherein the fixation barbs have a hemostatic profile comprising a circular base section extending to a trihedral-shaped end portion.
A connecting device adapted for end-to-end anastomosis of at least two body ducts through an intermediary prosthesis having extremities intubed in end portions of the ducts, the device comprising:
- a sleeve fitted at each end of the prosthesis of the intubed portions of the ducts, the sleeve comprising:
- a mesh cylinder capable of radial expansion between a stable minimal-diameter configuration and a final after-expansion configuration that is also stable, and
- a series of fixation barbs on each end of the cylinder and adapted to engage a portion of the prosthesis, a portion of the body duct, or a combination thereof surrounding the sleeve, the fixation barbs aligned at regular intervals and radially encircling the cylinder, wherein the fixation barbs have a hemostatic profile comprising a circular base section extending to a trihedral-shaped end portion.
A method for setting in place connecting devices adapted for end-to-end anastomosis of at least two body ducts through an intermediary prosthesis having extremities intubed in end portions of the ducts, comprising the steps of:
- intubing a first end of the prosthesis in an extremity of a first body duct;
- setting in place a first connecting device by introducing an inflatable balloon catheter into the prosthesis through an end of the prosthesis, the first connecting device comprising:
- a mesh sleeve capable of radial expansion between a stable minimal-diameter configuration and a final after-expansion configuration that is also stable, and
- a series of fixation barbs on each end of the sleeve and adapted to engage a portion of the prosthesis, a portion of the body duct, or a combination thereof surrounding the sleeve, the fixation barbs aligned at regular intervals and radially encircling the sleeve, wherein the fixation barbs have a hemostatic profile comprising a circular base section extending to a trihedral-shaped end portion;
- intubing a second end of the prosthesis in a second body duct;
- and
- setting in place a second connecting device by the catheter introduced into the prosthesis through an orifice in the prosthesis that is subsequently re-closed, the second connecting device similar in composition to the first connecting device.
The device according to claim 2, wherein the barbs are attached to the cylinder by soldering.
The device according to claim 2, wherein the barbs are attached to the cylinder by gluing.
The device according to claim 6, wherein the end portion of the intermediate barbs is inclined at an angle of about 5 degrees.
