Abstract

Rotational intravascular ultrasound (IVUS) catheters comprise of an ultrasound transducer, rotated by a flexible driveshaft, and contained within a saline-filled catheter/sheath. Before using the device, the sheath must be filled with saline, which serves as a biocompatible lubricant for rotation of the flexible driveshaft within the sheath as well as conducting ultrasound. When filling the sheath with saline, it is important to expunge any air bubbles from within the sheath, since these bubbles can block the ultrasound waves if they collect in the vicinity of the transducer, thus introducing artifacts in IVUS images.
