A SHUNT SYSTEM, SHUNT AND METHOD FOR TREATING AN OCULAR DISORDER

摘要

A shunt 10 for implantation in the human body for treating ocular disorders related to disorders of intraocular or intracranial pressure by providing for flow of aqueous fluid in the anterior chamber A of the eye and cerebrospinal fluid in the subarachnoid space B surrounding the optic nerve C. The shunt has a proximal end 12 which is implanted in the ocular anterior chamber and a distal end 14 which is implanted in the subarachnoid space. The shunt has a two-part construction, including a flexible distal tube 18 and a rigid proximal tube 20. The distal tube has a distal stop formation 26 near the distal end 14 which is located in the subarachnoid space upon implantation of the distal end, resisting withdrawal of the shunt. The proximal tube has a curved portion which conforms to the anatomical curvature of the ocular globe.
