Development of bioabsorbable braided vascular scaffolds for the intracranial circulation
… which can cause other health problems. Bioabsorbable stents have been postulated as a way to overcome the long-term disadvantages of metal stents. Commercial bioabsorbable stents have been developed for coronary artery diseases, although the design of coronary stents is different than …

The development of bioabsorbable hydrogels on the basis of polyester grafted poly(vinyl alcohol)
The present work describes the synthesis and characterization of amorphous and covalently crosslinked polymer systems based on poly(vinyl alcohol) and polyesters. The hydrogels prepared are biocompatible and hydrolytically degradable. The macroscopic properties, primarily the degradation rate, mass …

Mechanical properties of bio-absorbable materials
Bioabsorbable orthopedic fixation devices are conceptually more attractive than metallic devices in repairing damaged tissues or in fastening implants. Our study focuses on investigating bioabsorbable composites for potential use as materials for orthopedic appliances. The study focuses on …

Self-Assembling Peptide Nanofibers RADA16 and IEIK13 for Rapid Hemostasis
… thermal stability, cost effective, and bioabsorbable. Self-assembling peptide nanofibers RADA16 and IEIK13 provide a unique possibility to create a hemostat that meets all of these criteria. These short peptides self-assemble into nanofibers that entangle and gel in solution. Through the …

Biodegradable stents made of pure Mg and AZ91 alloy through SPS sintering
… proposed as biomaterials for the production of bioabsorbable stents and for other medical devices due to its harmless effect to human body when compared with other structural materials. In this work, the possibility to produce biodegradable stents made of magnesium starting from the powder is …

Use Of synthetic solid scaffolds to mechanically support a chondrocyte-seeded peptide hydrogel for articular cartilage repair
… using a synthetic solid scaffold, made of bioabsorbable polyglycolic acid:trimethylene carbonate (PGA:TMC) or expanded polytetrafluoroethylene (ePTFE), loaded with a chondrocyte-seeded self-assembling peptide hydrogel, [KLDL]₃. We hypothesized that these composite scaffolds would benefit …

Surface modification of traditional and bioresorbable metallic implant materials for improved biocompatibility
… surfaces of noble metal coatings, silicon, and bioabsorbable materials through ion beam irradiation in order to improve endothelialzation and bone cell adhesion. Gold, palladium, silicon, and iron manganese surfaces were patterned through ion beam irradiation using argon ions. The surface …
