Abstract: A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

Abstract: An accommodative hydraulic intraocular lens system (AHIOL) has a cylindrical actuator contained within which is a hydraulic lens assembly. The hydraulic lens assembly has a transparent elastically reconfigurable membrane coupled to a fixed focus lens by a bellows and a refractive hydraulic fluid contained in the space defined by the membrane, the bellows and the lens, and is maintained at the upper range of its diopter power by the elastic properties of the bellows, springs, or both.

The stent (112) includes an inflow end (120) and an outflow end (122), and surrounds and supports the heart valve (116). The sealing member (114) is connected to the inflow end (120) of the stent (112) and extends around a periphery of the stent (112). The sealing member (114) is connected to the inflow end (120) of the stent (112), overlaps a portion of the heart valve (116), and extends around an outer periphery of the stent (112).

Abstract: A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent extending between a proximal end and a distal end, the stent including an annulus section adjacent the proximal end and an aortic section adjacent the distal end. The annulus section has cells arranged in at least one annulus row, each annulus row having a same first number of cells, the first number defining a first cell density. The aortic section has cells arranged in at least one aortic row, each aortic row having a same second number of cells, the second number defining a second cell density, the first cell density and the second cell density being different. A valve assembly is disposed within the stent.

Abstract: A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.

Abstract: A prosthetic heart valve having an inflow end, an outflow end and a longitudinal axis extending from the inflow end to the outflow end includes a collapsible and expandable stent including a plurality of cells arranged in at least one row extending around a circumference of the stent. The stent further includes at least one engaging arm joined to one of the cells adjacent the outflow end and having a free end extending toward the inflow end, the engaging arm being movable between a loaded condition in which the engaging arm is oriented substantially parallel with the longitudinal axis of the stent, a partially-released condition in which the engaging arm forms a first angle with the longitudinal axis of the stent, and a fully-released condition in which the engaging arm forms a second angle with the longitudinal axis of the stent, the first angle being larger than the second angle.

Abstract: A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.
Abstract: A multifocal eye lenses including an optical part, which has a first optical side and an opposite second optical side viewed in the direction of a main optical axis (A) of the eye lens, and which has a plurality of annular optical zones that at least partly encircle the main optical axis (A) and are formed on at least one side, and zones each have at least one main sub-zone.
Abstract: A device and method for forming an adaptive optic in the capsule of a human eye is disclosed, comprising a capsular interface enclosing an optically acceptable medium. The device establishes a physiologic range of optical power in response to a range of ciliary contractile states. The preferred bi-phasic medium of the device is comprised of a solid three dimensional polymeric network suspended in a liquid aqueous phase and bonded to a capsular interface. The polymeric network provides shape to the capsular interface, optical power, and a physiologic response to the suspensory ligament. The three dimensional network of the bi-phasic medium mimics the stacked fiber configuration and elasticity of a natural lens. An alternative embodiment utilizing a single phase medium is also disclosed with associated structural features provided in the capsular interface.

Abstract: Provided herein are methods for treating an individual having (suffering from) an acute myocardial infarction and drug eluting stents useful for treating such individuals. These methods include treating an individual by introducing, such as by surgically inserting, at a site of an acute coronary artery occlusion upstream of the site of acute myocardial infarction, a drug eluting stent (DES) that is capable of eluting from 25 pg to 950 pg of IGF-1 directly into the coronary circulation. The treatment is specifically directed to stimulation of repair or survival of damaged cardiac muscle or left ventricular remodeling.

Abstract: A method of positioning an accommodating intraocular lens assembly in an eye can include implanting an accommodating intraocular lens assembly having a positive power lens in the eye. The accommodating intraocular lens assembly can also include a plurality of stanchions extending between base ends and distal ends. The base ends can be disposed in spaced relation to one another about a first arcuate periphery positioned in a ciliary sulcus of the eye. The distal ends can be disposed about a second arcuate periphery extending in a second plane positioned forward and outside of a capsular bag of the eye. The positive-power lens can be connected with the plurality of distal ends whereby a center of the positive power lens is moved along the central optic axis in response to contraction of the first arcuate periphery by contraction of the ciliary sulcus.
