An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

A medical implant may include an expandable anchor member having a lumen extending through the expandable anchor member from an inflow end to an outflow end; a plurality of valve leaflets disposed within the lumen extending through the expandable anchor member; a seal member disposed adjacent an exterior of the expandable anchor member; and a porous material extending from the seal member to the plurality of valve leaflets.

An example system for designing a patient matched implant for an orthopedic joint repair surgical procedure includes a memory configured to store a model of a bone of a patient; and processing circuitry. The processing circuitry may be configured to: obtain the model of the bone of the patient; obtain a template model of an implant; determine a shape of a surface of the implant; determine a volume between the shape of the surface of the implant and a surface of the bone defined by the model of the bone; generate, based on the determined volume and the template model, a patient matched implant model; and output a file representing the patient matched implant model.

Various aspects of the present disclosure are directed toward an embolic filter system. The embolic filter system generally includes a filter and an elongated element. In some examples, the elongate element extends to a position distal to a proximal end of the filter and operates to protect against medical devices entangling with the filter. In some examples, the elongate element is soft and compliant and operates with a hemostatic seal to provide for a hemostatic seal within a lumen of the elongate element while maintaining the lumen as a working lumen through which medical devices can be passed.

A system comprising a biomimetic electrochemical eye (EC-EYE) and a computing device is provided. The EC-EYE comprises: an ionic liquid device; a nanowire (NW) device that comprises the plurality of NWs; and a connection device configured to provide a plurality of currents associated with the plurality of NWs to a computing device. The computing device comprises one or more processors and a display device. The one or more processors are configured to: receive the plurality of currents from the plurality of NWs via the connection device; determine a plurality of pixel characteristics associated with a plurality of pixels based on the plurality of currents from the plurality of NWs; generate an image comprising the plurality of pixels based on the plurality of pixel characteristics; and provide the image to a display device. The display device is configured to display the image.

Various embodiments disclosed relate to contact lens including nanopores. A contact lens can include a nanoporous film including nanopores that are on an inner surface of the contact lens, and a backing lens on the nanoporous film. Various embodiments further include a biomarker-sensing region of the nanoporous film, a drug storage and delivery region of the nanoporous film, or a combination thereof.

A system for treating aortic dissection including an aortic dissection implant comprising an expandable anchoring structure and an elongate tubular structure. The expandable anchoring structure can be configured to apply radial force to the sinuses of the aortic root and/or the sinotubular junction when expanded. The elongate tubular structure can comprise an expandable support frame and one or more layers. The expandable support frame can be configured to extend from the descending aorta to the ascending aorta and curve along with a curvature of the aortic arch when expanded within the aorta. The one or more layers can comprise a first porous layer comprising an atraumatic outer surface positioned over the expandable support frame and a second non-porous layer positioned over a portion of the first porous layer. The second non-porous layer may be configured to be positioned on opposite sides of the aortic dissection and to be inflatable via blood flow to seal against the dissection.

A method of producing a bioabsorbable membrane includes: forming a liquid membrane by spin-coating a coating liquid containing a first bioabsorbable polymer and a solvent; and forming a dense layer by causing a porous membrane containing a second bioabsorbable polymer to contact the liquid membrane.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for altering blood flow in a vessel of a patient. The apparatuses, systems, and methods may include one or more anchor portions; a flow restriction portion having a section of reduced diameter relative to the one or more anchor portions; and a membrane component coupled to at least a portion of the flow restriction portion.
