Intended Use

The BOSS™ 8F Balloon Guide Catheter is indicated for use in facilitating the insertion and guidance of an intravascular catheter into a selected blood vessel in the peripheral and neurovascular systems. The balloon provides temporary vascular occlusion during these procedures. The balloon guide catheter is also indicated for use as a conduit for retrieval devices.

Device Description

The BOSS 8F Balloon Guide Catheter system is a sterile, single-use intravascular catheter. The BOSS 8F Balloon Guide Catheter is an 85 and 95 cm long, variable stiffness catheter utilizing a bifurcated dual port luer hub on the proximal end and a radiopaque marker band at the tip distal to the balloon. The catheter shaft has an annular inflation lumen and a coaxial central lumen with stainless steel coil and is braid reinforced. The hub central port leads to the central lumen to facilitate introduction of interventional devices through the central lumen. The inflation port is positioned at an angle to the central port, connecting to the annular inflation lumen, and is used to facilitate inflating and deflating the balloon with a syringe. The BOSS 8F Balloon Guide Catheter uses a distal hydrophilic coating to provide lubricity and reduce friction between the catheter shaft and the vessel wall. The BOSS 8F Balloon Guide Catheter is packaged with the 6F dilator to facilitate the option of direct access into the blood vessel without the use of an introducer sheath.

AI/ML Overview

This document describes the non-clinical performance testing for the BOSS 8F Balloon Guide Catheter, a medical device. There is no information regarding a study of an AI device. As such, I cannot provide details on factors like sample size, ground truth, expert qualifications, or comparative effectiveness studies related to AI.

However, I can provide the acceptance criteria and reported device performance based on the non-clinical bench testing for the BOSS 8F Balloon Guide Catheter.
