An injectable PEG/polyester thermogel with strong X-ray opacity was designed and synthesized through the conjugation of 2,3,5-triiodobenzoic acid to the hydrophobic end of the mPEG-PLA diblock copolymer for the first time.

Injectable nanoscale hydroxyapatite (nHA) systems are highly promising biomaterials to address clinical needs in bone tissue regeneration, due their excellent biocompatibility, bioinspired nature, and ability be delivered a minimally invasive manner. Bulk strontium-substituted (SrHA) is reported encourage growth by stimulating deposition reducing resorption, but there no detailed reports descri...

Nitinol (Nickel-Titanium) alloys exhibit a combination of properties which make these alloys particularly suited for self-expanding stents. Some of these properties cannot be found in engineering materials used for stents today. The paper describes the fundamental mechanism of shape memory and superelasticity. Material properties and device characteristics like elastic deployment, thermal deplo...

Bioresorbable stents (BRS) potential in treating coronary heart disease is still to be further developed. Current trends include research with new polymeric materials, the need for thinner struts combined appropriate mechanical properties, radiopacity and optimized local drug delivery. This work presents a novel solvent-cast direct-write (SC-DW) printing system manufacture BRS onto rotating cyl...
