Graft and method of making

A method of manufacturing a flow dividing graft structure, comprising:

• providing a section of graft material;
• expanding, layering, and shrink fitting the graft material with additional graft material in a predetermined manner about a shape pattern to make one or more graft leg members seamlessly coupled with a main portion of the graft;
• and
• removing the form from the graft.

A flow dividing graft structure, comprising:

• a main graft section;
• and
• a branch graft section coupled with the main graft section at an angled divider section;
• wherein the angled divider section is seamless and is suitable for dividing flow through the flow dividing graft structure.

A flow dividing graft structure formed by providing a section of graft material, expanding, layering, and shrink fitting the graft material with additional graft material in a predetermined manner about a shape pattern to make one or more graft leg members seamlessly coupled with a main portion of the flow dividing graft structure, and removing the shape pattern from the flow dividing graft structure, the flow dividing graft structure comprising:

• a seamless monolithic structure having a main section;
• and
• at least one seamlessly coupled branch section extending from the main section;
• wherein the flow dividing graft structure includes a seamless flow divider junction between the main section and the at least one seamlessly coupled branch section.
