An inlet fluid pathway is coupled to the inlet port and extends at least partially through the tube. A plurality of outlet fluid pathways extend at least partially through the body and branch from the inlet fluid pathway. A plurality of outlet ports are disposed on the body and coupled to the plurality of outlet fluid pathways. A disclosed inserter device for an ocular implantation procedure includes a handle, a needle, and a plunger. The needle is disposed on a distal end of the handle and configured to hold an intraocular drainage device. The plunger is coupled to the needle and disposed in the handle.Type: GrantFiled: December 12, 2019Date of Patent: March 16, 2021Assignee: NEW WORLD MEDICAL, INC.Inventors: Malik Y.

Patent number: 10905861Abstract: Articulation devices, systems, methods for articulation, and methods for fabricating articulation structures make use of balloon arrays, with inflation of the balloons locally altering articulation. Inflation fluid may be directed toward the balloons from an inflation fluid source via a series of channels, the balloons and channels included in a helical multi-balloon assembly. The balloons may be supported by encasing the helical balloon assembly in a polymer matrix, such as by winding the balloon assembly onto a mandrel and dip-coating some or all of the assembly in an elastomer such as a silicone, a urethane, or the like. The balloons may be supported by one or more spring, with loops of the spring(s) optionally being inward of the balloons, outward of the balloons, or interspersed between the balloons, and/or a mesh tube, braid, or other compliant materials may be included.Type: GrantFiled: April 24, 2018Date of Patent: February 2, 2021Assignee: Project Moray, Inc.Inventors: Timothy H.
