Current vascular access solutions all share the same limitation: they rely on a permanently open connection between an artery and a vein. While this high-flow connection is essential during dialysis, it remains active 24 hours a day, creating the conditions that drive many of the complications experienced by dialysis patients.<\/span><\/p>\n The XSGuard\u2122 Dynamic AVF takes a fundamentally different approach.<\/span><\/p>\n Instead of accepting continuous high blood flow as unavoidable, XSGuard actively controls blood flow by opening the artery-vein connection only when dialysis is required and closing it between treatments. This restores normal circulation during daily life while maintaining the high blood flow needed for efficient dialysis.<\/span><\/p>\n By addressing the root cause of vascular access complications\u2014continuous high and turbulent blood flow\u2014XSGuard has the potential to significantly improve patient outcomes and quality of life.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.22.1″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_row _builder_version=”4.22.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.22.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_video src=”https:\/\/www.xs-innovations.com\/wp-content\/uploads\/2025\/05\/28112023DAFV_invertedarm_final.mp4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_video][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.27.4″ _module_preset=”default” min_height=”181.8px” global_colors_info=”{}”][et_pb_row _builder_version=”4.22.1″ _module_preset=”default” min_height=”149.8px” custom_margin=”-40px|auto||auto||” custom_padding=”0px||6px|||” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.22.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font=”–et_global_body_font||||||||” text_text_color=”gcid-body-color” text_font_size=”16px” text_line_height=”1.1em” hover_enabled=”0″ inline_fonts=”Gravita HUM Regular” global_colors_info=”{%22gcid-body-color%22:%91%22text_text_color%22%93}” sticky_enabled=”0″]<\/p>\n The XSGuard\u2122 is a fully implantable vascular access device that is implanted using familiar vascular surgical techniques.<\/span><\/p>\n The device is implanted between the artery and vein using a short graft segment of less than one centimeter.
