Graft Device for Endogenous Tissue Restoration in Between Two Tubular Structures

Graft devices are provided addressing a long need for off-the-shelf small diameter replacement vessels to overcome the drawbacks of currently available alternatives. As they are available off-the-shelf, the graft devices do not require additional surgery to harvest it such as for a vein graft. A porous nature of the graft devices enables restoration process, which results in new natural and patient-own tissue, in contrast to currently existing vascular prosthesis that can never fully heal. A built-in graft support device over-comes the limited kink-resistance that is typical for these kinds of (electro-spun) porous devices. A zigzag pattern with alternating laminating and non-laminating areas enables the incorporation of the graft support device without the need for additional suturing or connecting the inner and outer layer for good lamination, while maintaining adequate kinkresistance.
