A literature review on pharmacologic therapy for abdominal aortic aneurysms

Angiologia e Cirurgia Vascular, 2023
Aortic aneurysms affect 3.3% of adults and there is a growing burden of small aneurysms detected, which may grow to need surgical repair. Still, we rely only on surgical therapy for this disease, left to monitor patients until they are candidates ...

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.
