Abstract
A catheterization system for forming dual sutureless anastomoses using two catheters connectable to one another. Once the fistula is healed, a dissolvable connection allows the catheters to separate one from the other and the separated pieces are extruded through normal bowel action. The two catheters may be connected in various ways. In one embodiment, a separate guide member may be used to pull a dissolvable suture through the first catheter. The suture is then attached to the second catheter and the suture may be used to pull the second catheter into contact with the first catheter so that the two catheters are closely connected by the suture. When the suture dissolves, the two catheters separate. In another embodiment, the first catheter has a section formed of a dissolvable mesh. The two catheters may be connected together by any of various types of connections. After a period of time, the mesh dissolves and allows the joined catheters to separate into two pieces.
