THE SOUNDPASS SOLUTION

EchoVent

Intelligent access. Real-time clarity.

EchoVent is being engineered to acquire ultrasound signals from within the ventricular-access pathway and translate those signals into localization feedback.

CLINICAL CONTEXT

Why ventricular access needs better information.

The target can be small, the anatomy can shift, and the clinical moment may leave little room for delay.

Time-sensitive

Ventricular access may be required on a compressed timeline in acute neurologic emergencies, making a practical bedside workflow essential.

Landmark-guided

Conventional bedside placement relies primarily on external anatomical landmarks and does not provide continuous visualization from the advancing catheter tip.

Anatomy can change

Trauma, edema, and ventricular shift can make the target smaller or move it away from its expected location.

DESIGN OBJECTIVE

A new approach to ventricular access.

EchoVent brings a miniature ultrasound transducer into the access pathway. The platform is being developed to identify signal transitions associated with anatomical interfaces and translate them into localization feedback while retaining familiar access geometry.

The advancing transducer encounters the near and far ventricular interfaces.

Interface peaks provide a one-dimensional depth signature.

AI-assisted processing allows translation of the one-dimensional signal into a spatial heat map to guide EVD catheter placement in one attempt.

THE ECHOVENT PLATFORM

Three integrated technologies. One familiar workflow.

Each component is being developed as part of a single investigational system for intraprocedural ventricular localization.

Ultrasound-tipped stylet

A miniature A-mode ultrasound transducer designed to fit within current EVD catheter luminal diameters and acquire tissue-interface signals during advancement.

Echolucent EVD catheter

A catheter architecture under development to support acoustic transmission while preserving a familiar ventricular-access workflow.

Real-time guidance platform

Investigational signal-processing and display software paired with a highly mobile tower designed for positioning over patient beds and surgeon comfort during EVD placement.
