Control of weft yarn or density improves biocompatibility of PET small diameter artificial blood vessels

“…Biomaterials used as implants are almost always accompanied with some liability. Examples of such problems include inflammation, thrombus, or tissue adhesion . Therefore, a substantial amount of effort has been directed at improving the biocompatibility of biomaterials.…”

“…Examples of such problems include inflammation, thrombus, or tissue adhesion. 1,2 Therefore, a substantial amount of effort has been directed at improving the biocompatibility of biomaterials. As all biomaterials approved by the FDA exhibit no cytotoxicity, some of the more likely sources of problems associated with biomaterials may involve their structural parameters as well as the chemical structure of the material.…”

Tribological properties study of lubricants for possible nanoclays reinforced biomedical applications

“…According to the study by Madl et al [9], there are certain toxicological concerns caused by orthopedic implants. Infers that good surgical implant procedure provides system stability leaving residues volumetric wear under wear composed of Cr nanoparticles (<100nm) with no content of Co. For implants with poor surgical implant position, distribution wear parti-cles are very large (> 1000 nm) and contains a higher con-centration of Co [8], which generate migration of wear debris which induce an inflammatory response, causing toxicity, osteolysis and subsequent loosening of the implant.…”

[9] Trying to provide a solution to the problem this study is focused on the prevalence of new systems of friction and wear in the ATR and new technologies applied to nano-technological processes. In a study by Alnaimat et al [10], polyvinyl alcohol (PVA) in different concentrations ex-posed to tribological tests with different combinations of CoCr, UHMWPE and PEEK generates COF reduction [9], but in a study by Kobayashia et al [11], using the PEG lubricant has high viscosity characteristics of high density; We can prolong the longevity of the ATR, wear processes, making the lubricant tribological tests to check its efficiency in material exposure Co-Cr [10].…”
