Among the many challenges of delivering stents is ensuring that the catheter remains flexible enough to navigate various vessel structures without kinking or breaking. State-of-the-art stent delivery systems are designed with exceptional kink resistance, enabling them to conform to different anatomical curvatures without compromising structural integrity. This feature empowers medical professionals to perform accurate interventions, even in complex regions, with enhanced confidence and control.
Hydrophilic Coating for Optimized Passability
The outer layer of modern stent delivery systems often features a patented hydrophilic coating, significantly enhancing the catheter’s ability to move through the body by reducing friction between the catheter and bodily tissues. This coating not only improves device maneuverability but also minimizes tissue damage, thus making procedures safer for patients. By reducing resistance and boosting passability, the hydrophilic coating represents a considerable advancement in the field of catheter design and functionality.
Radiopaque Markers: Precision in Positioning
Precision is paramount in medical procedures, especially when positioning a stent in a blood vessel or other delicate area. Today’s stent delivery systems incorporate radiopaque markers at the catheter tip, which allow real-time visualization of the device via imaging techniques like fluoroscopy.
