Shunt system, shunt and method for treating an ocular disorder

A shunt for treating an ocular disorder related to a disorder of intraocular or intracranial pressure by regulating intraocular pressure in an eye of a patient, the shunt comprising:

• a proximal shunt portion defining a proximal end which is implantable in an ocular anterior chamber of the patient and a distal shunt portion defining a distal end which is implantable in a subarachnoid space of the patient, the shunt defining a lumen extending longitudinally between the distal and proximal ends, the shunt having an enlarged distal stop formation near the distal end of the shunt, configured to be disposed in the subarachnoid space after implantation of a distal end region of the shunt in the subarachnoid space, for resisting withdrawal of the shunt after implantation in the subarachnoid space, and the shunt being flexible along a portion of a length of the shunt configured to conform to an outer anatomical curvature of an ocular globe, the proximal shunt portion including at least one outwardly-projecting ridge formation for resisting migration of the proximal shunt portion after implantation thereof in the ocular anterior chamber, the distal and proximal shunt portions being releasably connected at a connection point located along an outer surface of the ocular globe, with the lumen of the shunt extending continuously through the distal and proximal shunt portions, the proximal shunt portion having a rigid construction at the connection point which is configured to be along the outer surface of the ocular globe, wherein a portion of the proximal shunt portion is releasably received within the distal shunt portion.
