Patent number: 10729583Abstract: An implantable device for treatment of glaucoma of the eye. In one aspect, the device includes an elongate duct for diverting aqueous humor from the anterior chamber of the eye, the elongate duct having a central axis with a proximal end and distal end opposite one another. A least one element is spaced apart from the proximal end and the distal end of said elongate duct and extends radially outward beyond an outer surface of said elongate duct in at least two directions transverse to the central axis of said elongate duct, wherein the at least one element has a distal portion with a tapered profile facing the distal end of said elongate duct. The at least one element is configured to deform in a tissue passage leading into the anterior chamber of the eye as it is inserted into the tissue passage in response to forces applied by surrounding ocular tissue of the tissue passage. Other aspects are also described and claimed.Type: GrantFiled: July 30, 2018Date of Patent: August 4, 2020Assignee: InnFocus, Inc.Inventor: Leonard Pinchuk

Patent number: 10695218Abstract: A system for preparation of an implant and ab interno insertion of the implant into an eye including a handle having one or more actuators and an elongated shaft having an outer sheath and an elongate member positioned within a lumen of the tubular outer sheath. The system includes a recess sized for holding a patch of material fixed relative to the handle and a cutting member movable relative to the handle and to the recess. The cutting member cuts the patch of material into an implant as the cutting member moves towards a cutting configuration. The implant, once cut, is axially aligned with the lumen of the tubular outer sheath. The inner elongate member is movable relative to the tubular outer sheath to advance the implant into a deployment position in the lumen of the tubular outer sheath for delivery into the eye. Related devices and methods are provided.Type: GrantFiled: January 31, 2020Date of Patent: June 30, 2020Assignee: Iantrek, Inc.Inventor: Tsontcho Ianchulev

Patent number: 10632293Abstract: A delivery system for delivering an implant to a first space within a body of a patient including an elongate delivery member having a proximal portion, a distal portion, a lumen and a receiving area, the receiving area dimensioned for receipt of the implant. A deforming member is movable with respect to the delivery member from a first position to a second position to apply a force to the implant to deform the implant positioned in the receiving area of the delivery member.Type: GrantFiled: March 19, 2016Date of Patent: April 28, 2020Assignee: TVA MEDICAL, INC.Inventors: Michael Paris, Adam Dakin, Todd Polk, Mahesh Krishnamoorthy, Stephen Paris

Patent number: 10617421Abstract: The present invention relates to a connection stent and a method of manufacturing the stent. The connection stent includes: a body configured to form a plurality of cells through the intersection of wires, and provided in a hollow cylindrical shape; an upper head formed to extend from one end of the body to have a diameter larger than that of the body; and a lower head formed to extend from a remaining end of the body to have a diameter larger than that of the body. The upper head and the lower head are respectively placed to come into contact with insides of heterogeneous tissues. Accordingly, according to the present invention, there can be manufactured a stent which can connect heterogeneous tissues and form a bypass and which can provide sufficient expansion force and minimum axial force for the maintenance of the bypass formed as described above.Type: GrantFiled: May 24, 2018Date of Patent: April 14, 2020Assignee: M.I.
