Abstract The small diameter artificial blood vessel is synthesized with a diameter less than or equal to 6 millimetres. This technique has been used in coronary artery bypass grafting to treat coronary artery disease. Currently, the problem of coronary artery disease is still common, in addition to aortic aneurysm caused by the incompatibility of mechanical properties between the artificial blood vessel and the local blood vessel in the patient’s body. This research aims to solve the aforementioned problems using electrospinning and 3D printing technologies, as many types of materials are supported, all parameters are easy to change, and the cost is low. In this report, we describe a design for a small diameter polylactic acid (PLA) vascular graft fabricated by electrospinning with solutions of PLA in AC/DMF (1:1) 10, 12 and 15% w/v at 4 mm. The electrospun PLA nanofibers are tested for their morphology, contact angle, and seam strength. As the results, the fibres are still no same direction alignment due to insufficient rotation speed. The filament holding force is in the range of 1.90-2.71 N and the contact angles are greater than 90° because the samples are not wettable and have hydrophobic property. Further on, we will investigate other required properties, such as cell culture and other mechanical properties. Furthermore, we will compare the results with 3D printed artificial blood vessels with small diameter.

This paper designs a type of small artificial blood vessel in a composite structure, which the nano cellulose coating is attached to the tube blank. The properties of this type of artificial blood vessel - radical and axial tensile property, area of aperture gaps - are observed by an electron microscopy and analyzed to prepare for the further experiments.

Morphology And Mechanical Properties

In this paper, we prepared a scaffold composed of a polyurethane (PU) fibrous outside-layer and a gelatin-heparin fibrous inner-layer with mimicking morphology and mechanical properties of a native blood vessel by sequential bilayering electrospinning technology on a rotating mandrel-type collector. The scaffolds achieved the appropriate breaking strength (3.7 ± 0.13 MPa) and elongation at break (110 ± 8%). When the scaffolds were immersed in water for 1 h, the breaking strength decreased slightly to 2.2 ± 0.3 MPa, but the elongation at break increased up to 145 ± 21%. Heparin was released from the scaffolds at substantially uniform rate until the 9th day. The scaffolds were expected to mimic the complex matrix structure of native arteries, and had good hemocompatibility as an artificial blood vessel owing to the heparin release.
