  • Publication number: 20220395397
    Abstract: An implantable ocular drain includes a body and a compliant portion. The body includes a first end configured to seat in an anterior chamber of an eye. The first end includes an inlet for ingress of aqueous humor into the implantable ocular drain. The body further includes a second end configured to seat in a tear film of the eye. The second end includes an outlet to release a flow of the aqueous humor into the tear film. The body further defines a tortuosity and a fluid conduit. The body includes a lumen having a lumen length and a lumen cross sectional area. The lumen length and the lumen cross sectional area and the tortuosity are configured to control an intraocular pressure (IOP) of the eye by controlling the flow of the aqueous humor through the lumen. The compliant portion is at the second end.

  • Patent number: 11369384
    Abstract: Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.

  • Patent number: 10460003
    Abstract: In a client-server system where a client system presents a browser for user interaction, a browser user interface includes functionality for handling dynamic interface elements received by the browser in connection with received pages, presented as part of the browser user interface and modified in response to selected user input without requiring further interaction with a server. In addition to, or in place of, dynamic interface elements such as slide sheets, the browser user interface might also include a rotation display area, tool displays that can overlay a page, opaquely or semi-transparently, menu structures, and an ability for the user to modify a page layout without requiring server interaction.

  • Publication number: 20180177505
    Abstract: A novel barbed suture comprises improved retaining strength or anchoring ability within the tissue in both directions of the suture. The barbed suture of the present invention comprises a plurality of barbs which are made of filaments. The ends of the filaments are attached to the main body of the suture thread to form barbs. The barbs are flexible and allow tissue ingrowth. As a result, the barbed suture is allowed to be readily deployed in the tissue with high retaining strength in both directions of the suture. The retaining strength enhances the barbed suture's ability to hold tissue together with improved wound closure or tissue approximation performance.
