Patent ID: 8162963

Claim:
A device for use in making an angled anastomosis between first and second tubular fluid conduits in the body of a patient, said device comprising: a unitary structure having a main body disposed annularly about a longitudinal axis, having a proximal end portion with a proximal end, and a distal end portion with a distal end, and adapted for passing the first tubular conduit through an annulus defined by the main body; an exterior of said main body configured to be inserted through an opening in the second tubular conduit; at least one first member extending radially from said proximal end portion and, in an undeformed configuration, angled toward a proximal direction of said device, relative to said longitudinal axis, and at least one second member extending radially, in said undeformed configuration, from said proximal end portion and angled toward a distal direction of said device, relative to said longitudinal axis, said members extending from said proximal end portion configured to abut against an external wall of the second conduit upon angulation of said main body with respect to a wall of the second tubular conduit; locking members fixed to said distal end portion and slidably received by said proximal end portion, wherein, upon buckling of said distal end portion, free ends of said locking members slide to extend proximally of said proximal end portion; said distal end portion being configured to buckle in response to axial compression of said device, wherein said distal end portion plastically deforms and is incapable of passing through said opening after buckling and exerts a compressive force between the first conduit and the wall of the second conduit upon buckling, while maintaining the angled configuration of the main body with respect to the second conduit.
