  • Patent number: 10532201
    Abstract: A drug administration device includes a substrate having a first surface, a projection extending from the first surface, and a solid drug. One direction that intersects with the first surface is a first direction, and one direction that extends along the first surface is a second direction. A groove serving as a receiving section is formed in the projection. The groove defines a cavity recessed in the first direction toward the substrate and extends in the second direction to open to a section of the peripheral surface of the projection. The drug is received in the groove.

  • Patent number: 10517759
    Abstract: The invention relates generally to medical devices and methods for reducing the intraocular pressure in an animal eye and, more particularly, to stent type devices for permitting aqueous outflow from the eye's anterior chamber and associated methods thereof for the treatment of glaucoma. Some aspects provide a self-trephining glaucoma stent and methods thereof which advantageously allow for a “one-step” procedure in which the incision and placement of the stent are accomplished by a single device and operation. This desirably allows for a faster, safer, and less expensive surgical procedure.

  • Patent number: 10441747
    Abstract: Methods and kits for delivering pharmaceutical agents to an adventitia and other regions outside an external elastic lamina (EEL) surrounding a blood vessel utilize a catheter having a needle. The needle is positioned in up to 5 mm beyond the EEL and delivers an amount of a pharmaceutical agent sufficient to circumferentially permeate around the blood vessel and, in many cases, extend longitudinally and radially along the blood vessel. Confirmation that a delivery aperture of the needle lies beyond the EEL may be required before delivering the pharmaceutical agent. In one example, catheters are used to deliver dexamethasone and other anti-inflammatory agents to a peripheral vasculature and other vasculature to treat peripheral vascular disease and other conditions.

  • Patent number: 10406028
    Abstract: A surgical tool for inserting a spile or plug into the punctal opening of a meatus such as a lacrimo-nasal canaliculus comprises an oblong, hollowed member shaped and dimensioned to be conveniently manipulated with one hand and having at one end a punctal opening and meatus-dilating shaft and, at the opposite end, a plug inserter. The dilating shaft has a cross-diameter substantially equal to the cross-diameter of the plug and is terminated by a conical spike. The inserter comprises a tip extending axially from the member and having, at its distal end, a cup whose internal geometry is commensurate with a cap at the proximal end of the plug. A penetration-resisting bearing surface is provided by the cup rim. A notch through the cup wall improves visualization of the plug during insertion. A steel wire running through the inserter has its distal end inserted into the cap of the plug.
