3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

In silico assessment of histotripsy-induced changes in catheter-directed thrombolytic delivery

Frontiers in Physiology, 2023
Introduction: For venous thrombosis patients, catheter-directed thrombolytic therapy is the standard-of-care to recanalize the occluded vessel. Limitations with thrombolytic drugs make the development of adjuvant treatments an active area of research ...

Intravital Multimodal Imaging of Human Cortical Organoid Transplantation in a Mouse Model of Chronic Stroke

Advanced Science, EarlyView.
A multimodal intravital imaging platform enables longitudinal tracking of human cortical organoids transplanted into chronic stroke lesions. By combining surgical microscopy, MRI, bioluminescence imaging, and two‐photon fluorescence microscopy, the platform captures graft placement, viability dynamics, and cellular‐scale morphology in vivo, offering a ...

Recurrent high-risk pulmonary thromboembolism treated with repeated thrombolytic therapy could be helpful for certain patients: a case report and review of the literature

European Journal of Case Reports in Internal Medicine, 2023
Acute pulmonary thromboembolism (PTE) is considered the third most frequent acute cardiovascular syndrome behind myocardial infarction and stroke, with annual incidence rates ranging from 39 to 115 per 100,000 people and ranking high among the causes of ...

Thrombolytic therapy in review

The Journal of Emergency Medicine, 1993
The use of thrombolytic agents for both coronary and noncoronary indications is a rapidly progressing field. There has been substantial debate over which disease processes ultimately benefit from the use of thrombolytic agents. In addition, many recent studies have focused on comparing different thrombolytic agents and dosing regimens in an attempt to ...

Thermochemical Micro‐Explosion for Prompt Thrombolysis via Proximal Injection of Liquid Alkali Metal

Advanced Science, EarlyView.
We report a micro‐explosive thermochemical thrombolysis (METCT) therapy via injectable liquid alkali metal encapsulated in dimethyl silicone (LAM@oil). METCT enables prompt and safe vascular recanalization within 90 s. Critically, the LAM@oil system demonstrates significantly higher thrombolytic efficacy compared to clinically available thrombolytic ...

Hyperacute Interleukin‐1β Production and Neutrophil Extracellular Trap Formation in the Cerebral Circulation of Stroke Patients with Large Vessel Occlusion

Annals of Neurology, EarlyView.
Acute ischemic stroke due to large vessel occlusion is associated with rapid intravascular immune activation. Analysis of arterial blood sampled distal to the thrombus during mechanical thrombectomy revealed increased extracellular adenosine triphosphate (ATP) and interleukin‐1β (IL‐1β) levels, evidence of inflammasome priming in monocytes, and ...
