Robotic Assisted Ultrasound‐Guided Endovascular Stent Implantation in a Vascular Model

Abstract

BackgroundEndovascular procedures are the preferred method for treating peripheral arterial disease. However, limited imaging options during these procedures, such as X‐rays and contrast media, expose patients and healthcare professionals to potentially harmful radiation. This study introduces a robotic ultrasound system (RUSS) for navigating endovascular procedures in order to reduce radiation and provide additional information.MethodsThe RUSS comprises a seven‐degree‐of‐freedom robotic arm that navigates an ultrasound transducer across a specific region of interest. The system is controlled by a self‐programed software designed to navigate the robotic arm in a methodical and reproducible manner using a foot switch.ResultsAn endovascular surgeon investigated the guidance and visibility of various guidewires and successfully implanted three stents in a vascular leg phantom using the RUSS without further radiation exposure.ConclusionsThe innovative set‐up has several potential applications, including radiation‐free endovascular procedures as well as health screening and diagnostic support in vascular medicine.
