Device Description

The MRXperion Injection System is a software-controlled, electromechanical medical device used for the administration of intravenous MR contrast media and saline into the human vascular system for diagnostic studies in magnetic resonance imaging (MRI) procedures. Commonly referred to as an automated injection system, it is designed to allow a user to fill disposable syringes and then to perform an injection with a user-programmed volume and flow rate.

The MRXperion Injection System is comprised of a Scan Room Unit (SRU), Control Room Unit (CRU) and Single Use, Disposable Syringe Kit.

The SRU is located within the scan room whereas the control room unit is not. The SRU, via a wired connection, interfaces with the control room unit. The CRU, also known as the workstation, includes a graphical user interface for the injector. The operator can use the touchscreen display to manage protocols and initiate and execute injections. However, the SRU can be used to also initiate and execute injections.

The fluids are delivered from a single use only, sterile disposable set that includes one 65 mL syringe for contrast media and one 115 mL syringe for saline.

The injection system is intended to be used in an MR suite. The MR suite may be located in a mobile medical imaging trailer. The injection system is intended to be operated by personnel with training and experience in MR procedures and use of MR injection systems. Operators will consist of radiological technologists trained in the use of the equipment. This system is intended for use with the general patient population, including adults and pediatrics.

The MRXperion Injection System subject to this submission includes modified hardware and software as compared to the most recent clearance (K182276). The submission also includes an additional connectivity accessory, Imaging System Interface (ISI2) Module. The design changes do not involve any changes to the MRXperion MR Injection System Syringe Kit.
