Project Overview

During diagnostic and therapeutic image-guided endovascular procedures, there is a requirement for multiple injections of contrast medium and continuous delivery of saline flush solution. Currently, contrast medium delivery requires manual connection of a syringe to the delivery catheter for each contrast injection. Care must be taken so that air bubbles or small thrombi are not inadvertently injected. Since, in a typical procedure, this sequence is often repeated over 50 times, this adds significant time to a procedure. Manual injection of contrast also limits the ability to reproduce bolus characteristics and requires that the operator remain near to the x-ray source during image acquisitions. We would like to develop a method and apparatus that would allow connection to a saline flush and contrast medium source at the start of a procedure with the ability to automatically inject pre-programmed contrast injections, maintain continuous flush delivery and retain access to the catheter lumen for device and guide wire manipulation and delivery. There is a requirement that this also allows free catheter manipulation and the ability to insure that air and thrombi are not present.
