  • Patent number: 11020583
    Abstract: Connectors interfacing a mechanical circulatory system with a patient's natural vasculature are provided herein. Such connectors include aortic connectors that facilitate fluid coupling of an outflow graft tube from an implanted blood pump with a patient's aorta. Aortic connectors can include a substantially planar portion configured for sealed attachment with a wall of the aorta and a tubular connector portion extending from an inlet opening to an outlet opening. The substantially planar portion can include a flexible membrane for attachment to an outer surface of the aorta and/or a flange for engagement with an inner surface of the aorta. The tubular connector can extend from the substantially planar portion at a pre-determined angle and include one or more attachment features to facilitate rapid fluidly sealed attachment to the outflow graft tube.

  • Patent number: 11020579
    Abstract: A patient may be treated by implanting a combined arterial venous fistula graft implant in a limb of the patient. The combined implant includes a body with a vessel segment in contact with an artery and a first tubular segment for attachment to an end of a vein to form an arterial venous fistula, and a second tubular segment with an attached segment of artificial tubing for attachment to the vein at a second location to form an arterial venous graft. The arterial venous graft may be exclusively used to form hemodialysis for a period of time after the implanting step, while the arterial venous fistula matures.

  • Patent number: 10945883
    Abstract: Intraocular drainage devices, intraocular implantation procedures, and inserter devices for intraocular implantation procedures are disclosure. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. An inlet port is disposed on the distal end of the tube and configured to receive an influent fluid from an anterior chamber of an eye. 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.

  • Patent number: 10905861
    Abstract: 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.
