Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants

Advanced Science, EarlyView.
The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

Advanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Endovascular Salvage After False Lumen Misdeployment of Thoracic Endovascular Aortic Repair or the Frozen Elephant Trunk in Aortic Dissection: A Case Report of Two Patients

Vascular Specialist International
Thoracic endovascular aortic repair (TEVAR) and the frozen elephant trunk (FET) are well-established treatment options for aortic dissection (AD). Inadvertent misdeployment of a TEVAR stent graft or FET into the false lumen (FL) can lead to serious ...
