  • Patent number: 10987195
    Abstract: A medical device includes a first valve and a second valve. The first valve includes a manifold having a first opening, a second opening, and a third opening, and an element movable within the manifold and spring-biased to close the first opening. When biased to close the first opening, air flows from the second opening to the third opening. The second valve is configured to provide a flow of pressurized gas to the first valve to move the element to close the third opening. The first valve and the second valve are configured, upon moving the element to close the third opening, to interrupt the flow of air from the second opening to the third opening and to allow the flow of the pressurized gas to exit the second opening.

  • Patent number: 10952897
    Abstract: The present invention provides a method of relieving intraocular pressure by inserting a drainage device into the sclera near the trabecular meshwork from a remote location. The path of insertion is made from a corneal incision and avoids contact with the conjunctiva and tenons tissue. The drainage device comprises a tube like structure and may contain a barb at one end to secure the drainage device. A delivery device may be used to insert the drainage device. The delivery device may be inserted through a corneal incision and directed to the desired area for insertion in to the sclera. The delivery device may then be activated to shoot the drainage device into the sclera to promote increased drainage of aqueous humor and reduce the build up of intraocular pressure.

  • Patent number: 10492948
    Abstract: A method of treating glaucoma in an eye utilizing an implanted shunt having an elastomeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera of the eye with an outflow end of the elastomeric drainage tube open to an outer surface of the plate. An inflow end of the drainage tube tunnels through the sclera and cornea to the anterior chamber of the eye. The drainage tube collapses upon initial insertion within an incision in the sclera and cornea, or at a kink on the outside of the incision, but has sufficient resiliency to restore its patency over time. The effect is a flow restrictor that regulates outflow from the eye until a scar tissue bleb forms around the plate of the shunt. The plate desirably has a peripheral ridge and a large number of fenestrations, and a longer suturing tab extending from one side of the plate to enhance visibility and accessibility when suturing the shunt to the sclera.

  • Patent number: 10238535
    Abstract: Lacrimal implants and related methods providing secure, wedgable retention within a lacrimal punctum and associated canaliculus of an eye are disclosed. The lacrimal implants can comprise an implant body configured for at least partial insertion through the lacrimal punctum and into the canaliculus. The implant body can include first and second portions, and can extend from a proximal end of the first portion defining a longitudinal proximal axis to a distal end of the second portion defining a longitudinal distal axis. The implant body can be configured such that, when implanted using an integral dilator, an angled intersection exists between the proximal and distal axes. In this way, at least a portion of the implant body can be biased against at least a portion of the lacrimal canaliculus located at or more distal to a canalicular curvature, thereby retaining an implanted position of the lacrimal implant using anatomical structures.

    Abstract: A shunt device for directing fluid from a human head, and methods thereof are provided herein. The device can be mounted at a skull and include a first catheter that extends into a portion of the head such as a lateral ventricle. The first catheter can covey fluid through, and past a valve to a shunt body. The shunt body can include openings, allowing the fluid to reenter the head, for example at the subarachnoid space. The shunt body can also include other openings that can be associated with a second catheter. Fluid can thus also be conveyed out of the body or to a subgaleal pocket.

  • Patent number: 9949856
    Abstract: The present disclosure provides an inflatable weight control device that is implanted long-term with an endoscope in obese and bariatric human patients to promote early and prolonged satiety. The device includes a flexible, inflatable member coupled to a valve body assembly and an elongated durable module residing within the flexible member. The flexible member is selectively inflated to form two bulbs with a central passageway extending through the bulbs and the valve body assembly. Once the bulbs are inflated, the device is retained within the patient's pyloric valve to form a gastric outlet obstruction wherein chyme accumulates and then is directed through the central passageway to reach the patient's duodenum. Due to its unique configuration, the implanted device reduces gastric outflow which results in early and prolonged satiety when the patient consumes normal-sized meals or food portions, thereby reducing food consumption and increasing the patient's weight loss.
