Hierarchical microelectrodes create localized fields that boost reversible tissue adhesion while avoiding frictional or abrasive surface damage.

Localized microscale electric fields and Wenzel-Cassie interfaces enable strong reversible implant adhesion without tissue electroporation or abrasion.

Hierarchical microstructures and localized electric fields improve implant adhesion while avoiding electroporation, electrofusion, and frictional tissue damage.

A layered silk fibroin and hyaluronic acid hydrogel improves wound healing while controlling gel formation and local active-agent delivery.

A GelMA-ECM-collagen scaffold loaded with Gli1+ MSCs regenerates cranial sutures to prevent resynostosis and normalize intracranial pressure.

Flexible leaflets around the mesh opening let the esophagus dilate during peristalsis while resisting upward sliding to reduce hiatal hernia recurrence.

A magnetic distal locking liner replaces strap threading, making prosthetic donning easier while keeping attachment secure.

A switchable motor supply lets an orthotic actuator deliver high starting torque and higher speed with a smaller, lighter energy store.

A liquid anti-ingrowth coating cures partway through surgical mesh, blocking adhesion on one side while preserving tissue integration on the other.

Patient-specific body simulation predicts orthotic fit and load interactions before setup, helping reduce discomfort and harmful compensatory postures.

A threaded rod and adapter unit cut friction and manual effort when pressing larger bone cement volumes from a cartridge.

Hydrophilic PEG and PHEMA networks create stable sensor biosurfaces that improve biomolecule anchoring for sensitive analyte detection.

A deflection element lets the belt rest on a contact surface instead of threading through eyelets, enabling one-handed orthopaedic fastening.

Prestretched liner regions limit distal axial stretch to reduce pistoning and milking while preserving radial conformability and comfort.

A lattice elastomer liner moves air and moisture through apertures to reduce heat buildup, skin irritation, and fit instability.

Complementary serrations create a self-locking orthotic interface that transfers load to the forearm while staying modular and easy to release.

Disposable hydrogel compression with a piston, receptacle, and flask cuts sterilization time, contamination risk, and graft damage.

A nucleic acid and chitosan-derivative composition improves tissue repair stability and biocompatibility without toxic crosslinking agents.

Interconnected pores in a resorbable collagen scaffold improve tissue infiltration, support wound healing, and allow visual monitoring.

Flexible starlock leaflets let the esophagus dilate during peristalsis while resisting upward sliding that can trigger hiatal hernia recurrence.

Bioorthogonal Diels-Alder crosslinking builds an ECM-like hydrogel with tunable stiffness, controlled biodegradation, and low cytotoxicity.

A pre-molded parastomal mesh uses a raised center and bowel clearance channel to lower recurrence while avoiding obstruction.

A single anatomic mesh combines abdominal and groin coverage to reinforce large hernia defects without using multiple separate meshes.

Cost-effective MA-PMCA-PEG and GEL-MEA cross-linking forms stable biodegradable 3D hydrogel scaffolds with tunable mechanics and anti-viral properties.
