Publication number: 20230142433Abstract: A glaucoma shunt for draining a fluid from an eye to a tissue surrounding the eye, the glaucoma shunt being implantable within tissue of the eye, the glaucoma shunt includes a shunt body that is formed from a microporous material that is arranged so as to form a reservoir within the shunt body; and a conduit in fluid communication with the reservoir, the conduit being insertable into the eye such that the fluid at a distal end of the conduit is allowed to flow through the conduit and accumulate within the reservoir, wherein the microporous material transitions from a hydrophobic state to a hydrophilic state as the fluid that is accumulated in the reservoir diffuses to the tissue surrounding the eye through the microporous material so as to provide a variable flow resistance as the microporous material transitions from the hydrophobic state to the hydrophilic state.Type: ApplicationFiled: November 3, 2022Publication date: May 11, 2023Inventors: Jeffrey C.

Publication number: 20230054622Abstract: Glaucoma treatment systems are disclosed. In various example, the glaucoma treatment systems include a body and a fluid conduit configured to facilitate an evacuation of fluid, such as aqueous humor, from a fluid-filled body cavity, such as an anterior chamber of an eye. In some examples, the fluid conduit is soft and compliant, and the glaucoma treatment system includes one or more stiffening members coupled with the fluid conduit to temporarily stiffen the fluid conduit and help aid in the delivery of the glaucoma treatment device. In some examples, the stiffening members are removable from the fluid conduit after the glaucoma treatment system has been implanted.Type: ApplicationFiled: November 3, 2022Publication date: February 23, 2023Inventors: Peter J.

Publication number: 20220378611Abstract: An implantable delivery device for dispensing a medicament that includes a first microporous material that is bonded to a second microporous material. The first microporous material has a first microporous layer including a plurality of pores sized to permit tissue ingrowth and a second microporous layer including a plurality of pores sized to permit tissue ingrowth. The second microporous material has a third microporous layer including a plurality of pores sized to resist tissue ingrowth and a fourth microporous layer including a plurality of pores sized to permit tissue ingrowth. The second microporous layer is bonded to the third microporous layer to thereby form a reservoir for receiving the medicament. The first and second microporous materials are configured to meter a rate at which the medicament is dispensed from the reservoir when the delivery device is implanted.Type: ApplicationFiled: May 26, 2022Publication date: December 1, 2022Inventors: Jérôme S. Conia, Peter J. Roeber, Jeffrey C. Towler
