Medical device for deployment within an eye for management of intraocular fluids

Abstract

The disclosure relates to ophthalmic implants, specifically a flexible, self-expanding spacer device deployable in subconjunctival, sub-Tenon's, or suprachoroidal spaces to manage intraocular fluids. The device addresses limitations of fixed-resistance drainage and fibrosis-related failure in glaucoma surgery by maintaining a controlled three-dimensional reservoir (bleb space) for aqueous humor outflow while minimizing tissue trauma. In one aspect, a shape-memory body transitions from a compressed, delivery-compatible state to an expanded configuration defining a convex internal volume, optionally with collapse-resistant reinforcements and tissue-engaging elements for atraumatic stabilization. Preferred embodiments include anterior relief geometry to avoid corneal contact and posterior flow-directing features to promote posterior bleb formation and uniform pressure control. A delivery member with a reduced-profile, tapered piercing tip and optional bent shaft enables minimally invasive ab externo implantation and controlled, coaxial deployment. Advantages include streamlined single-step delivery, stable long-term bleb architecture, reduced hypotony and fibrotic encapsulation, and compatibility with trabeculectomy and shunt-based outflow.
