Magnetic Milli‐Spinner for Robotic Endovascular Surgery

Advanced Materials, EarlyView.
The magnetic milli‐spinner, with its unique structural design, achieves rapid and stable navigation through complex vasculature at speeds up to 23 cm·s−1. It further enables multifunctional treatment, including localized suction and shear for efficient clot removal, targeted drug delivery, and in situ embolization for aneurysm therapy, establishing it ...

An unusual approach for the treatment of oesophageal perforation: Laparoscopic-endoscopic cooperative surgery

Journal of Minimal Access Surgery, 2017
Boerhaave syndrome describes a transmural oesophageal rupture that develops following a spontaneous, sudden intraluminal pressure increase (i.e. vomiting, cough).

Ureteral stent technology: Drug-eluting stents and stent coatings

Asian Journal of Urology, 2015
Ureteral stents are commonly used following urological procedures to maintain ureteral patency. However, alongside the benefits of the device, indwelling stents frequently cause significant patient discomfort (pain, urgency, frequency) and can become encrusted and infected.

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Efficacy of LVIS vs. Enterprise Stent for Endovascular Treatment of Medium-Sized Intracranial Aneurysms: A Hemodynamic Comparison Study

Frontiers in Neurology, 2019
Background: We conducted a computational fluid dynamics (CFD) study and compared the treatment of medium-sized intracranial aneurysms with LVIS and Enterprise stent-assisted coil embolization (SACE) to determine the effects of hemodynamic changes caused ...

Low‐Strain Flexible Ink‐Based Sensors Enable Hyperelastic Inflation Perception Via Geometric Patterning for Balloon‐Type Robots

Advanced Robotics Research, EarlyView.
Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.

Removal of a partially covered stent by endoscopic substent dissection

Journal of Digestive Endoscopy, 2016
Herein we describe a new technical endoscopic removal of embedded partially covered esophageal stent that was inserted to treat a iatrogenic perforation of esophagus. Usually, partially covered stents can be removed by the stent-in-stent technique.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
