AI Technical Summary

Technical Problem

Existing cerebrospinal fluid (CSF) catheter equipment is easily blocked due to contact with surrounding tissues, resulting in CSF discharge obstruction, and the equipment has a short life and needs to be replaced frequently.

Method used

A CSF catheter device with a distancer is designed that ensures that the outlet end of the catheter is always at a distance from the inner membrane, avoiding contact, thereby reducing the risk of closure and maintaining the catheter in an optimal position through an expandable distancer.

Benefits of technology

It effectively extends the service life of the catheter, reduces the risk of closure, ensures the normal discharge of CSF, and reduces the replacement frequency.

Abstract

To provide a shunt device and method for shunting cerebrospinal fluid.SOLUTION: A shunt device for shunting cerebrospinal fluid (CSF) from a CSF containing space to a sinus system cavity (21) comprises a tubular inlet element, a flow restricting part, and a tubular outlet element having an outlet end (17) with an outlet opening (19) for insertion into the sinus system cavity (21), and one-way valve preventing a flow in the direction from the outlet opening to the inlet opening. The shunt device further comprises a distancer (35), said distancer being provided at the outlet end (17) of the tubular outlet element.SELECTED DRAWING: Figure 4
