Langmuir: Natural Tissue Microenvironmental Conditions Modulate Adhesive Material Performance

Nuria Oliva, Sagi Shitreet, Eytan Abraham, Butch Stanley, Elazer R. Edelman, and Natalie Artzi. Natural Tissue Microenvironmental Conditions Modulate Adhesive Material Performance. Summary: We designed and optimized tissue-responsive adhesive materials by matching material and tissue properties. A two-component material based on dextran aldehyde and dendrimer amine provides a cohesive gel through aldehyde–amine cross-linking and an adhesive […]

Journal of Controlled Release: Enhanced Drug Delivery Capabilities from Stents Coated with Absorbable Polymer and Crystalline Drug

Carlyle WC, McClain JB, Tzafriri AR, Bailey L, Zani BG, Markham PM, Stanley JR, Edelman ER. Enhanced Drug Delivery Capabilities from Stents Coated with Absorbable Polymer and Crystalline Drug. Summary: Current drug eluting stent (DES) technology is not optimized with regard to the pharmacokinetics of drug delivery. A novel, absorbable-coating sirolimus-eluting stent (AC-SES) was evaluated for […]

Journal of Controlled Release: Stent elution rate determines drug deposition and receptor-mediated effects

Tzafriri AR, Groothuis A, Price GS, Edelman ER. Stent elution rate determines drug deposition and receptor-mediated effects. Summary: Drug eluting stent designs abound and yet the dependence of efficacy on drug dose and elution duration remains unclear. We examined these issues within a mathematical framework of arterial drug distribution and receptor binding following stent elution. […]
