Clinical Investigation of Clinical Safety and Performance of the SP-GRIPFLOW, Selective Cerebral Perfusion Catheter When Used for Cerebral Perfusion During Aortic Arch Repair

Fuji Systems Corporation149 enrolled

Overview

The purpose of this study is to determine if the SP-GRIPFLOW catheter (the catheter designed by Fuji Systems) is safe and how well it functions. The information from this research will be used to help decide if the device should be approved for sale in the European Union. The SP-GRIPFLOW catheter may not yet be used by investigators outside of the study. Through the study, FUJI will prove that the target flow as measured by the flow through the catheter(s)(cumulative flow for multiple catheters) was confirmed in 95% of cases.

The SP-GRIPFLOW catheter is a catheter that is used to transport blood from the aortic arch to your brain during surgery on the aorta. The procedure in which the catheter is used does not differ from the procedure as performed with current catheters. Furthermore, the SP-GRIPFLOW catheter is used in a similar manner as other catheters that are currently on the market. Contrary to available catheters, the SP-GRIPFLOW has a ribbed surface on the balloon end of the device, which aims to improve the grip of the balloon in order to reduce chances of dislocation from the target artery. Clinical trials are needed to obtain or expand knowledge about the safety, suitability and effi-cacy of medical devices. This is why the legislative authority has specified in the law on medi-cal devices that new medical devices must be clinically tested. The clinical trial that we present to you here was - as required by law - granted a favourable opinion by an ethics committee and approved by the competent authority. This clinical trial will be conducted at up to 5 sites in the European Union; a total of approximately 149 persons will participate in it. The study is being initiated, organised, and financed by Fuji Systems Corporation, the sponsor of this study.

Outcomes

Primary Outcomes

"Successful perfusion" defined by flow rate through the catheter (mL/kg/min)

The primary endpoint is defined by blood flow through the SPGRIPFLOW and perfusion of the brain during open surgical repair of the distal aortic arch. Blood flow (and perfusion) is assessed by the flow rate through the cannula(s) compared to the target flow rate. Successful perfusion is defined when the flow rate through the catheter(s) equals the target flow rate (mL/kg/min). The perfusion flow rate will be monitored throughout the procedure. The target flow rate will be preoperatively defined by the investigator

Time frame: The enrolment period is expected to take approximately 15 months. The duration of the subject's participation is circa 1 month. The total expected duration of the clinical investigation is, therefore, approximately 16 months.

Secondary Outcomes

"Adequate flow rate" assessed by a clinically relevant through the catheter(mean and maximum flow rate「mL/kg/min」). endpoints

The secondary endpoint of this study will focus on assessment of adequate flow rate through the SP-GRIPFLOW. Whether the SPGRIPFLOW allows for an adequate flow rate will be assessed by a clinically relevant flow through the catheter(s) (mean and maximum flow rate). A clinically relevant perfusion flow rate of 10-15 mL/min/kg was defined from scientific literature.
