Device features silicone plate with 13 mm convex radius; barium-impregnated for radiopacity (CT, MRI, plain film). Includes silicone tube with elbow attachment for posterior chamber insertion; flange with fixation holes for scleral attachment. Used by ophthalmic surgeons in surgical setting to manage intraocular pressure in refractory glaucoma patients; provides alternative drainage pathway to reduce pressure; prevents vision loss. ## Clinical Evidence No clinical data provided; substantial equivalence based on design comparison and surgical performance similarity to predicate. ## Technological Characteristics Medical grade silicone construction; barium-impregnated for radiopacity; 13 mm convex radius plate; non-valved drainage mechanism; includes silicone tube with elbow connector. ## Regulatory Identification An aqueous shunt is an implantable device intended to reduce intraocular pressure in the anterior chamber of the eye in patients with neovascular glaucoma or with glaucoma when medical and conventional surgical treatments have failed. ## Special Controls *Classification.* Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Devices—Part I: Evaluation and Testing,’ ” (2) “510(k) Sterility Review Guidance of 2/12/90 (K90-1),” and (3) “Aqueous Shunts—510(k) Submissions.” ## Predicate Devices - Baerveldt Glaucoma Implant ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

It is constructed entirely of medical grade silicone with an episcleral plate. The implant is molded to conform to the curvature of the glove with a 13 mm convex radius. The silicone plate is barium impregnated to increase ultrasound resolution and identification with CT scan, MRI, and plain skull films. A silicone tube connected to an "elbow" for insertion into the posterior chamber is attached to the anterior surface of the plate. The proximal portion of the plate has a flange with two large fixation holes for scleral attachment. {1} K955455 ## Device Comparison The Baerveldt Pars Plana Glaucoma Implant is substantially equivalent to the Baerveldt Glaucoma Implant. Both share identical plates (BG 102-350 and BG 101-350, respectively) and differ only in that the pars plana device has a silicone "elbow" to facilitate placement of the tube in the posterior chamber. ## Comparison Data Surgical performance of the both devices indicate that both perform comparably. 0000086 --- **Source:** [https://fda.innolitics.com/submissions/OP/subpart-d%E2%80%94prosthetic-devices/KYF/K955455](https://fda.innolitics.com/submissions/OP/subpart-d%E2%80%94prosthetic-devices/KYF/K955455) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
