Embodiment Construction

[0049] The anastomosis device comprises a first attachment unit 1 and a second attachment unit 2, wherein, figure 1 A first unit 1 is illustrated, figure 2 A second unit 2 is shown. The attachment unit is preferably made of titanium. The attachment unit may also be partially or completely made of resorbable material.

[0050] figure 1 Thus a perspective view of the first attachment unit 1 . This unit has a generally cylindrical body 101 . The body has a rear portion 102 and a front portion 103 , the outer diameter of the front portion 103 being slightly larger than the outer diameter of the rear portion 102 . In the example shown, the cells are cylindrical, but other cylindrical shapes, such as elliptical cylindrical shapes, are also possible.

[0051] The means for attaching the unit to the end of the catheter and the means for connecting the unit to a second unit extend substantially axially from the front edge of the front part 103 .

[0052] The means for attaching...

Abstract

The invention relates to an anastomosis device for anastomising two vessel parts together. First and second attachment units are included. They are connectable to each other and attachable to a respective vessel part. According to the invention each attachment unit has a vessel receiving surface (120) with an area (121) that has a roughness with a large number of small sharp projections arranged to partly penetrate the wall of the received vessel part without reaching through said wall. The invention also relates to a method for anastomosis and to a use of the invented anastomosis device.

Description

technical field [0001] The present invention relates in a first aspect to an anastomosis device for anastomosis of two catheter parts or other tubular organs, said device comprising a first attachment unit and a second attachment unit, said attachment unit being Attached to respective catheter portions and interconnectable, each attachment unit has a through bore defining a longitudinal axis of the attachment unit, and each attachment unit has a catheter receiving surface. [0002] The invention relates in a second aspect to a method for anastomosing two catheter parts together, attaching first and second attachment units to respective catheter parts and interconnecting the attachment units , each attachment unit has a through hole defining the longitudinal axis of the attachment unit. [0003] The invention relates in a third aspect to a use of the invented device. [0004] In this application, for example, the definitions of axial, radial, and tangential are relative to th...
