Production and characterisation of bioresorbable polymers and polymer-glass composites for application in cardiac stents
Bioresorbable polymeric cardiac stents are a promising technology for treating cardiovascular diseases, but current poly-L-lactide (PLLA) stents have been limited by poor mechanical properties and slow degradation. Materials with increased strength and stiffness are needed, to reduce the required …

Bioresorbable Electrospun Tissue Scaffolds of Poly(ethylene glycol-b-lactide) Copolymers for Bone Tissue Engineering
Poly(α-hydroxy esters) are a class of biocompatible resorbable polyesters including poly(lactic acid) (PLA) and poly(glycolic acid) (PGA) that are FDA-approved for clinical use. Preliminary tissue culture studies have demonstrated that these poly(α-hydroxy esters) support bone tissue development …

REGENERATION OF ELECTROSPUN BIORESORBABLE VASCULAR GRAFTS: A PHENOMENON ASSOCIATED WITH VASCULAR GRAFT PROPERTIES AND MACROPHAGE PHENOTYPES (M1/M2)
<p>Macrophages (MФ) and mast cells are important cell types in the context of tissue remodeling and regeneration. Mast cells participate in the early stages of wound healing and modulate the acute inflammatory responses to biomaterials. Mast cells can secrete a myriad of different cytokines by the …

A combined experimental and computational framework to optimise processing and design of poly(L-lactic acid) bioresorbable stents
… can trigger undesirable immunological responses. Bioresorbable polymer stents offer an attractive solution, providing a temporary scaffold that resorbs once the artery heals. However, polymeric stents are mechanically inferior to their metallic counterparts, requiring thicker struts to provide …

The formulation of a bioresponsive ceramic bone replacement
… These problems have led to the development of bioresorbable bone replacement materials. Bioresorbable biomaterials are expected to degrade at a rate which is proportional to the rate of formation of new bone tissue. In the majority of cases, however, resorption is driven by simple dissolution …
