Abstract:
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 in the sinus system cavity ( 21 ), and a one-way valve preventing flow in a 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.

Claim (Index 1):
A shunt device comprising\n a tubular inlet element ( 7 ) having an inlet end ( 9 ) with an inlet opening ( 11 ) for insertion in a cerebrospinal fluid (CSF) containing space ( 13 ), such as a subarachnoid space or a brain ventricle, a tubular outlet element ( 15 ) having an outlet end ( 17 ) with an outlet opening ( 19 ) adapted for insertion in a sinus system cavity ( 21 ), such as sinus transversus or vena jugularis, a distancer ( 35 ;  135 ;  235 ) provided at the outlet end ( 17 ) of the tubular outlet element ( 15 ) for avoiding contact between the shunt and surrounding tissue, and for maintaining the outlet end of the tubular outlet element at an essentially fixed distance from endothelium tissue surrounding said tubular outlet element, wherein said tubular elements ( 7 ,  15 ) comprise an inner lumen extending through each tubular element ( 7 ,  15 ), and wherein the inner lumen of the tubular inlet element ( 7 ) and the inner lumen of the tubular outlet element ( 15 ) are operably connected to allow CSF to flow through the shunt device in the direction from the inlet opening ( 7 ) to the outlet opening ( 19 ), a flow restricting part ( 31 ) positioned between the inlet opening ( 9 ) and the outlet opening ( 19 ), and a one-way valve ( 33 ) preventing CSF to flow in a direction from the outlet opening to the inlet opening.
