A Study Evaluate Aqueduct's Smart External Drain
A Study to Evaluate the Performance and Safety of Aqueduct's Smart External Device (SED) Compared to Standard EVD Drains

To evaluate the performance characteristics of the Smart External Drain (SED) compared with standard EVD drains in the hospital setting, specifically:

  • Number, type and duration of staff interactions.
  • Regulating and controlling ICP and CSF drainage.
  • Maintaining system control with patient movement.
In this two day clinical trial, subjects will be observed on Day 1 of study during their routine treatment and using their already existing EVD. On Day 2 of study; subjects will be switched to the Smart External Drain for monitoring and management of ICP and CSF
Not Applicable
Intervention Model: Single Group Assignment
Intervention Model Description:
In this study the subject will act as their own control and will be treated on day one with the standard of care EVD and then on Day 2 treated with the SED.
Masking: None (Open Label)
Primary Purpose: Treatment
  • Hydrocephalus
  • Hydrocephalus in Children
  • Tumor, Brain
Device: Smart External Drain - SED
Subject will be treated on Day 2 with the SED. ICP and CSF volumes will be recorded at prespecified intervals while subject is stationary and while subject is engaged in protocol-driven directed movements.
Single Arm study
Single Arm study In this study, the subject will act as their own control. On Day 1 of the two day study, the subject will be observed while treated on their standard EVD. On Day 2, the subject will be treated with the Smart External Drain (SED).
Intervention: Device: Smart External Drain - SED
