The material properties of arterial prostheses change following ingrowth of tissues in vivo. A porous silicone rubber arterial prosthesis was implanted in dogs, and it was found that half of the pores became filled with tissue after 3 months of implantation. The prosthesis has a 6-mm inside diameter, a wall thickness of 1 mm, length of 10 cm, and a porosity of 30%. The solid silicone from which the prosthesis is derived has a Young's modulus and tensile strength of 10 MPa. a. What is the most important factor in the success of the artificial vascular graft? b. The silicone rubber graft leaked blood. What would you do to prevent the leakage of blood when implanted? c. Determine the wall tension assuming a (high) blood pressure of 200 mm Hg immediately after implantation: T = P q r; 133.3 Pa = 1 mm Hg. d. Calculate the maximum force (N) on the arterial wall developed by the blood pressure (200 mm Hg). e. Would the silicone rubber be adequate for the artificial artery if a safety factor of 10 is required for it? f. What is the name of the anticoagulant used to prevent clotting of the prosthesis?
