Obstruction: status <strong>and</strong> needs<br />
• Proximal catheter obstruction (60%)<br />
• Coat<strong>in</strong>gs: no proven solutions yet, but promis<strong>in</strong>g<br />
• Active methods: <strong>in</strong>trigu<strong>in</strong>g but research stage<br />
• Better CSF control may reduce failure (OSV)<br />
• Valve obstruction (<strong>30</strong>%)<br />
• Possible issues with ih valve designs: complex flow<br />
path, small gaps, CSF contacts <strong>in</strong>tricate parts<br />
• Little‐to‐no activity to reduce valve obstruction<br />
• Need <strong>in</strong> vitro biological models to evaluate<br />
