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 ...

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.

A novel small-caliber bacterial cellulose vascular prosthesis: production, characterization, and preliminary in vivo testing [PDF]

, 2016
Vascular grafts are used to bypass damaged or diseased blood vessels. Bacterial cellulose (BC) has been studied for use as an off-the-shelf graft. Herein, we present a novel, cost-effective, method for the production of small caliber BC grafts with ...

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 ...

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.

Stenting or balloon angioplasty of stenosed autologous saphenous vein grafts in pigs [PDF]

, 1994
In a model of early and aggressive vein graft stenosis in pigs, an intervention was performed with a single stent (n = 12 grafts), multiple stents (n = 6), or balloon angioplasty (n = 6), while grafts with mild stenoses were left untreated (n = 8).

Early Outcomes After Total Arch Replacement With Frozen Elephant Trunk in Elderly Patients With Acute Type A Aortic Dissection

AGING MEDICINE, EarlyView.
Across seven centers (2015–2023), we studied 1634 ATAAD patients undergoing TAR+FET and, after propensity matching (n = 699), compared elderly (≥ 60) versus non‐elderly (< 60) outcomes. Elderly patients had higher 30‐day mortality and complications (log‐rank p = 0.002), supporting individualized hybrid strategies, organ‐protective perioperative care ...
