Advanced Functional Materials, EarlyView.A hybrid‐nested microneedle/cryogel scaffold (MQW‐CMg‐MOF) is designed for efficient biofilm removal and accelerated healing of diabetic wounds. The scaffold shows substantial biofilm removal in vitro and in a preclinical diabetic swine biofilm‐infected wound model compared to the control.

The Impact of a Nurse-Driven Foley Catheter Removal Protocol on Catheter Associated Urinary Tract Rates in Critical Care Areas [PDF]
, 2017 Background: Indwelling urinary catheters serve a purpose in critical care; however, they can also pose a risk for patients. With increased catheter use, there is an increased risk of developing a catheter associated urinary tract infection (CAUTI ...

Biofilm Control by Active Topography with Mucin Coating
Advanced Functional Materials, EarlyView.This study reports a new antifouling strategy based on a bioinspired design. Mucin coating enhances biofilm control by active topography with beating micron‐sized pillars. Besides the mechanical force of beating pillars, the antibiofilm activities also involve biological factors since mucin coating inhibits swarming motility and c‐di‐GMP synthesis in ...

In-Vitro MPI-Guided IVOCT Catheter Tracking in Real Time for Motion Artifact Compensation [PDF]
, 2019 Purpose: Using 4D magnetic particle imaging (MPI), intravascular optical coherence tomography (IVOCT) catheters are tracked in real time in order to compensate for image artifacts related to relative motion. Our approach demonstrates the feasibility for bimodal IVOCT and MPI in-vitro experiments. Material and Methods: During IVOCT imaging of a stenosis

Model-Based Pose Estimation of Steerable Catheters under Bi-Plane Image Feedback [PDF]
arXiv, 2023 Small catheters undergo significant torsional deflections during endovascular interventions. A key challenge in enabling robot control of these catheters is the estimation of their bending planes. This paper considers approaches for estimating these bending planes based on bi-plane image feedback.

Improving Catheter Segmentation & Localization in 3D Cardiac Ultrasound Using Direction-Fused FCN [PDF]
arXiv, 2019 Fast and accurate catheter detection in cardiac catheterization using harmless 3D ultrasound (US) can improve the efficiency and outcome of the intervention. However, the low image quality of US requires extra training for sonographers to localize the catheter.

Neural Network Reconstruction of the Left Atrium using Sparse Catheter Paths [PDF]
arXiv, 2023 Catheter based radiofrequency ablation for pulmonary vein isolation has become the first line of treatment for atrial fibrillation in recent years. This requires a rather accurate map of the left atrial sub-endocardial surface including the ostia of the pulmonary veins, which requires dense sampling of the surface and takes more than 10 minutes.
