A Single‐Component Adhesive Sponge Based on Blood‐Triggered and Autopenetrative Adhesion for Robust Vascular Closure

open access: yesAdvanced Science, EarlyView.
This study presents MonoSeal, a single‐component adhesive sponge powered by the novel Autopenetrative Adhesion (APA) mechanism. Unlike traditional adhesives, which require external stimuli, APA enables strong tissue adhesion under dynamic, high‐pressure bleeding conditions. MonoSeal's ability to autonomously seal large‐size arterial defects underscores

Recovery from repeated sudden hearing loss in a patient with Takayasu’s arteritis treated with hyperbaric oxygen therapy: the first report in the literature [PDF]

open access: yes, 2017
Hearing loss has been rarely reported in Takayasu's arteritis, presents as sudden sensorineural hearing loss and usually responds well to corticosteroid therapy.

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

open access: yesAdvanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Enhanced Embolic Signal Analysis through Ensemble Deep Learning Techniques Utilizing Transfer Learning and Layer Freezing Strategies

open access: yesAdvanced Intelligent Systems, EarlyView.
A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Monitoring of the central blood pressure waveform via a conformal ultrasonic device. [PDF]

open access: yes, 2018
Continuous monitoring of the central-blood-pressure waveform from deeply embedded vessels, such as the carotid artery and jugular vein, has clinical value for the prediction of all-cause cardiovascular mortality. However, existing non-invasive approaches,

Fibulin-4 is essential for maintaining arterial wall integrity in conduit but not muscular arteries [PDF]

open access: yes, 2017
Homozygous or compound heterozygous mutations in fibulin-4 (FBLN4) lead to autosomal recessive cutis laxa type 1B (ARCL1B), a multisystem disorder characterized by significant cardiovascular abnormalities, including abnormal elastin assembly, arterial ...

Collaborative Multirobot Navigation‐Assisted Magnetic Catheter Guidance and Shape Perception with Vascular Ultrasound and Electromagnetic Tracking

open access: yesAdvanced Intelligent Systems, EarlyView.
The article develops a collaborative multirobot navigation system‐assisted magnetic catheter guidance and shape perception method using the information fusion of robotic vascular ultrasound imaging and electromagnetic tracking to reconstruct the 3D catheter's shape and vasculature. Results verify the effectiveness of the system and the potential of the

Use of Nuclear Magnetic Resonance Imaging Angiography to Follow-Up Arterial Remodeling in an Animal Model [PDF]

open access: yes, 1998
Appropriately sized arteries in small animals may be possible models for studying the remodeling process as occurs after arterial balloon injury in humans. Magnetic resonance imaging (MRI) is able to noninvasively image tissue in vivo.
