biomer

07/01/1989 - "Retrieved grafts of Biomer and B-PEO-4K showed mural thrombi along the graft length, while thrombus formation on B-PEO-4K-HEP and H-S grafts was limited to the anastomotic sites. "
02/01/1988 - "The average surface area of the Biomer blood sacs covered with thrombus was 45 +/- 32 mm2. "
02/01/1988 - "Three of the four explanted Biomer blood sacs showed visible red thrombus, and all four showed small areas of white thrombus. "
07/01/1995 - "The results show that the heparin release from Biomer/poly(NiPAAm)-coated surfaces resulted in a significant reduction of thrombus formation on test surfaces in contact with venous blood as compared to control surfaces."
11/01/1988 - "In ex vivo A-A shunt experiments under low flow and low shear conditions, all heparinized surfaces exhibit significant prolongation of occlusion times compared to Biomer controls, indicating an ability of immobilized heparin to inhibit thrombosis in whole blood."

06/24/1985 - "Chronic arterial-thromboembolism was initiated by segments of polyurethane (Biomer) cannula introduced into chronic arteriovenous shunts. "
07/01/1979 - "A time-dependent phase of thrombus deposition followed by thromboembolism was observed on the PVC and Silastic shunt surfaces but not on the Biomer surface. "

07/01/1989 - "The effect of surface integrity on the performance properties of Biomer (Ethicon, Inc, Somerville, NJ) a segmented polyurethane used in many blood contacting devices, is being investigated using uniaxial tensile tests in air at room temperature, and biaxial fatigue tests in deionized water at body temperature. "
01/01/1985 - "On the other hand, Biomer did not show a decrease of fatigue strength after lipid absorption. "

02/01/1988 - "Use of a semiquantitative scale to assess renal infarction demonstrated that nine of 10 animals with a surface-modifying additive copolymer blend blood sac had infarction less severe than the mean infarct score of the animals with a Biomer sac. "

06/01/1996 - "Increased polyurethane mineralization was observed due to calciphylaxis with 60-day rat subdermal explants of Biomer, Mitrathane, and PEU-2000 (calcium levels, respectively, 4.13 +/- 0.56, 18.61 +/- 2.73, and 3.37 +/- 0.22 microgram/mg, mean +/- standard error) as compared to control explants (calcium levels, respectively, 1.22 +/- 0.1, 12.57 +/- 0.86, and 0.20 +/- 0.86 microgram/mg).
