A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Isolated double chambered right ventricle as a rare cause of sudden death in infancy

Egyptian Journal of Forensic Sciences, 2016
Isolated double-chambered right ventricle (DCRV) is a rare form of congenital heart disorder in which the right ventricle is divided into a high-pressure inlet portion and a low-pressure outlet portion by an anomalous muscle bundle. Rarely, autopsy cases

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

A Constraint‐Based Analytical Framework for Design‐Space Analysis and Material Screening of Tubular Multilayer Dielectric Elastomer Pumps for Extracorporeal Circulatory Applications

Advanced Materials Technologies, EarlyView.
A constraint‐based analytical framework maps the coupled effects of material properties, structural parameters, and operating conditions in tubular dielectric elastomer pumps for extracorporeal circulatory applications. The approach defines performance boundaries through mechanical, electrical, and hydraulic constraints and identifies feasible design ...

Removal of an inferior vena cava filter that had migrated to the right ventricle by off-pump ventriculotomy and direct-vision snare capture: a novel hybrid technique

Journal of International Medical Research, 2019
Inferior vena cava filter (IVCF) migration to the right ventricle is a life-threatening condition. Conventionally, on-pump ventriculotomy is required if the endovascular retrieval is compromised.
