Described herein is a method comprising molding a first component from a first feedstock comprising a first material powder and a first binder, molding a second component from a second feedstock comprising a second material powder and a second binder, placing the first component and the second component in physical communication with each other in order to form an assembled component, removing the first binder and the second binder from the assembled component and performing a sintering operation on the assembled component so as to bond the first component and the second component together.

An car cleaner is provided that includes an clongated handle, a spoon, and a disc intermediate the spoon and the disc.

A transcatheter prosthesis with radially compressed and expanded configurations. An elongate member encircling at least a portion of the prosthesis, and configured to provide a seal between the prosthesis and a native anatomy when the prosthesis is deployed in the radially expanded configuration. The elongate member may be a resilient elongate member having a radially contracted state, when in tension, to hold at least the portion of the prosthesis in the radially compressed configuration, and having a radially expanded state, when relaxed, to provide the seal between at least the portion of the prosthesis and a native anatomy when the prosthesis is deployed. A system for delivering the transcatheter prosthesis may include a delivery catheter having an elongate cinching member encircling at least a second portion of the prosthesis, wherein the elongate cinching member is configured to hold the second portion of the prosthesis in the radially compressed configuration.

Disclosed herein are implantable dual-valve devices having first and second valve structures, a connector coupled to the structures, and first and second sealing members coupled on each side of the device, along with related methods of deploying such devices.

An intraocular lens system may include a base that may include an annular body, an opening extending through the annular body in an axial direction of the annular body, and a recess extending circumferentially about the opening. The system also may include a lens that may be insertable into and removable from the recess. The lens may include a central optic, a first tab protruding radially away from the central optic, and a second tab protruding radially away from the central optic. The second tab may be more resistant to compression in a radial direction than the first tab. The first tab may include a first arm protruding radially away from the central optic, a second arm protruding radially away from the central optic and extending away from the first arm, and a third arm extending from the first arm to the second arm. Movement of one or more of the first, second, and third arms may result in deformation of the first tab.

Provided is a covered endovascular stent-graft comprising a first membrana tectoria for modeling a vascular shape and a stent-graft skeleton fitted to the outside of the first membrana tectoria, at least part of the outer surface of the stent-graft skeleton being covered with a second membrana tectoria; the first membrana tectoria and the second membrana tectoria are combined so that at least part of the stent-graft skeleton is covered between the first membrana tectoria and the second membrana tectoria, wherein the first membrana tectoria and/or the second membrana tectoria is/are a polyvinylidene fluoride resin membrana tectoria. The polyvinylidene fluoride resin membrana tectoria of the covered endovascular stent-graft makes the cost reduced and has good mechanical properties and biological properties.

The present technology is generally directed to adjustable shunting systems for draining fluid from a first body region to a second body region. The adjustable shunting systems include an actuation assembly for controlling the flow of fluid through the system. For example, the actuation assembly can include one or more fluid inlets in fluid communication with an environment external to the system. The actuation assembly can further include one or more actuators configured to move a corresponding control element to control the flow of fluid through the fluid inlets. The actuator can also have a first actuation element and a second actuation element configured to move the control element between a first position in which the control element substantially prevents fluid flow through the corresponding inlet and a second position in which the control element does not substantially prevent fluid flow through the fluid inlets.

Prosthetic valves having a frame and at least one leaflet. The leaflet comprises means for allowing fluid that is behind the leaflet to pass through to the front of the leaflet when the leaflet is not in the closed position. The prosthetic valve includes a leaflet moveable between an open position that permits antegrade flow through the prosthetic valve and a closed position that prevents regurgitant flow through the prosthetic valve, the leaflet having an aperture or gap, or a separation of portions of the leaflet to allow a flow or exchange of fluid between a front and back of the leaflet, when the leaflet is not in the closed position.

Described embodiments are directed toward prosthetic valves having a support structure and at least one leaflets. The leaflet comprises means for allowing fluid that is behind the leaflet to pass through to the front of the leaflet when the leaflet is not in the closed position. The prosthetic valve includes a leaflet moveable between an open position that permits antegrade flow through the prosthetic valve and a closed position that prevents regurgitant flow through the prosthetic valve, the leaflet having an aperture or gap, or a separation of portions of the leaflet to allow a flow or exchange of fluid between a front and back of the leaflet, when the leaflet is not in the closed position.
