摘要： Ophthalmic devices having elastic electrodes are disclosed herein. An example ophthalmic device may be an intraocular lens that includes a support structure, two optical windows, two immiscible fluids, and an elastic electrode. The support structure may have an inner surface defining an aperture with first and second optical windows disposed on opposite sides of the support structure and spanning the aperture. The two immiscible liquids may be disposed in a cavity formed by the aperture and the first and second optical windows, and the elastic electrode may be disposed on the inner surface. The elastic electrode may be formed from an elastic metal alloy having a minimum yield strain of 0.25%.

摘要： Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve can include an annular frame having an inflow end, an outflow end and a central longitudinal axis extending from the inflow end to the outflow end. The valve can include a support layer, where a first portion of the support layer extends circumferentially around the central longitudinal axis along an outer surface of the frame and a second portion of the support layer extends circumferentially around the central longitudinal axis axially beyond the inflow end of the frame. The valve can further include a valvular structure, where at least a portion of the valvular structure is connected to the second portion of the support layer and is unsupported by the frame.

摘要： A leaflet support device can be configured to improve the competence of a native heart valve. In some examples, the leaflet support device can include a frame and a support leaflet coupled to the frame. The support leaflet can include a support leaflet free edge configured to move correspondingly with a leaflet of the native heart valve to an open position and move correspondingly with the leaflet of the native heart valve to a closed position.

摘要： A surgical prosthetic heart valve has a supporting structure and a plurality of leaflets, the supporting structure generally having an annular shape with a blood flow channel defined in the annular shape and having opposite inflow and outflow sides along an axial direction of the annular shape, the plurality of leaflets connected to the supporting structure to control the blood flow channel to open or close. The supporting structure includes a first annular band and a second annular band, both of which are provided with deformable sections spaced from each other in the circumferential direction for allowing diameter expansion of the respective annular bands. The surgical heart valve achieves the diameter expansion of the annular bands through the deformable sections, thereby addressing the problem of postoperative variation in a valve-in-valve operations.

摘要： Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a first balloon carried on its distal end, and a second balloon that includes a distal section overlying at least a portion of the first balloon and a proximal section. The catheter distal end is introduced into the main vessel and positioned through the ostium and stent into the branch until the first balloon is disposed within the stent. The first balloon is expanded to anchor the stent, and the second balloon is expanded to flare the first end of the stent. Optionally, the first balloon is expanded further, e.g., to expand the stent within the branch body lumen and/or dilate the lesion.

摘要： A prosthesis includes a tubular graft, a prosthetic valve component, an inflow stent, an outflow stent, and a plurality of body stents disposed between the inflow and outflow stents. Each stent is a sinusoidal patterned radially-expandable ring having a first set of crowns and a second set of crowns, with the first set of crowns disposed closer to an inflow end of the tubular graft than the second set of crowns. The prosthesis is configured to be resistant to backfolding and/or buckling during deployment thereof.

摘要： An implantable prosthetic device can include a hybrid frame movable between a radially compressed configuration and a radially expanded configuration. The hybrid frame can include a mechanically-expandable first sub-frame comprising a plurality of struts pivotably coupled to one another, and a plastically deformable second sub-frame coupled to the first sub-frame. When the hybrid frame is in the expanded configuration, the second sub-frame can be configured to resist radial compression of the frame.
