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 ...

Surgical repair of an aortoesophageal fistula after salvage thoracic endovascular aortic repair: a case report

Journal of Medical Case Reports
Background An aortoesophageal fistula can prove to be fatal. Salvage thoracic endovascular aortic repair as a bridging therapy and radical surgery with thoracotomy should be considered while treating aortoesophageal fistula without spontaneous closure ...

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 ...

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 ...

Force‐Electric Nanotentacles of Tantalum Implant Accelerate Cellular Energy Metabolism/Crosstalk for Immunomodulation‐Vascularized Bone Integration

Advanced Science, EarlyView.
A biomimetic force‐electric nanotentacle‐enabled tantalum (Ta) implant with surface‐nanostructured LiTaO3 (n‐LiTaO3) was first developed via laser nanofabrication combined with Li+‐induced in situ reaction, enabling the transduction of ultrasound into bioelectrical cues.

Passive Aortic Counterpulsation to Reduce Pressure Pulse During Aortic Prosthesis Insertion and Reduce Endoleaks Formation: A Preliminary In Silico Investigation

Sci
Over 10% of patients undergoing aortic endograft implantation experience endoleaks within a few years. In the case of type 1a endoleaks, a crack forms between the aorta and the prosthesis collar, allowing blood to pass.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Advanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Retinal vessel segmentation using the 2-D Gabor wavelet and supervised classification [PDF]

, 2006
—We present a method for automated segmentation of the vasculature in retinal images. The method produces segmentations by classifying each image pixel as vessel or nonvessel, based on the pixel’s feature vector. Feature vectors are composed of the pixel’
