  • Publication number: 20240374424
    Abstract: A shunt for treating glaucoma comprises a silicone rubber duct for diverting aqueous humor from a chamber of a patient's eye and a fixation body frictionally located on the duct in an arrangement permitting sliding displacement of the fixation body, for fixing and sealing the duct within scleral tissue surrounding the eye. The duct has a rigid proximal portion having a proximal end and a deformable distal portion locatable in the scleral channel and having a distal end. The distal portion is severable, allowing a surgeon to cut the distal portion to a desired length corresponding to the anatomical dimensions of the patient's eye and a required bleb position. The proximal portion has a capillary lumen having a diameter which is smaller than a diameter of a lumen of the distal portion, thereby reducing a flow rate of aqueous humor along the capillary lumen.

  • Publication number: 20230218440
    Abstract: A shunt 200 for treating glaucoma in a patient during and/or after vitreoretinal surgery involving the use of a tamponading agent comprising a gas or oil bubble 50. The shunt includes a tubular body 12 having a proximal end 14 which is implantable in the vitreous cavity C of a patient and a distal end which is implantable in the subarachnoid space of the patient. The tubular body defines a lumen 18 extending between the distal and proximal ends. The shunt includes an occlusion body 32 defining a number of micro-passages 34 inflow communication with the lumen 18. The micro-passages are configured in terms of their size and number to provide sufficient surface tension and viscosity resistance in order to prevent the tamponading agent from passing through the micro-passages into the lumen, yet allow sufficient aqueous fluid from the vitreous cavity to travel along the micro-passages into the lumen 18 in order to regulate intraocular pressure.
