A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

Advanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

3D‐Printed Titanium Implants with Bioactive Peptide‐Polysaccharide Scaffolds for Personalized Bone Reconstruction

Advanced Healthcare Materials, EarlyView.
Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout

Study of a Novel Bi‐Layered Thermoplastic Polyurethane Patch for Congenital Diaphragmatic Hernia

Advanced Materials Interfaces, EarlyView.
Large congenital diaphragmatic hernia remains a challenge due to the poor compatibility of current prostheses. To tackle this problem, a bilayer thermoplastic polyurethane patch with tunable mechanical properties is engineered, whose fibrous side supports rapid fibroblast and myoblast colonization, while the smooth film limits adhesions.
