  • Patent number: 10780200
    Abstract: An apparatus (10) for controlling flow of fluid from a wound site of a patient may include a chamber (28) connectable to a wound site and a reservoir (16). The chamber (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The chamber (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the chamber (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the chamber (28) from the second state to the first state.

  • Patent number: 10758412
    Abstract: The invention relates to a stainless steel device for permanent insertion into the sclerocorneal limbus, with different drainage and anchorage systems, enabling the aqueous humour to discharge through one or more virtual spaces from the anterior chamber to an intrascleral space in cases of simple glaucoma or to the equatorial episclera in cases of complex glaucoma, such as neovascular glaucoma. The space is virtual, not real, as in the case of the tubular device. It enables the aqueous humour to discharge slowly and continuously, minimizing the possibility of the chamber being flat or of germs penetrating through the device. Furthermore, the anchorage system is less aggressive, thus reducing the possibility of bleeding.

  • Patent number: 10729583
    Abstract: 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.

  • Patent number: 10695218
    Abstract: 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.

  • Patent number: 10617421
    Abstract: 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.
