Abstract: An accommodating intraocular lens comprises a first lens component, a second lens component, and an adhesive between portions of the two lens components. The cured adhesive bonds the lens components to form a fluid chamber. The lens components are bonded to one another along a seam which extends circumferentially along at least a portion of the lens components. The lens components may comprise the same polymer material. The cured adhesive also comprises the polymer or a prepolymer of the polymer to provide increased strength. The polymer is hydratable such that the lens components and the cured adhesive therebetween can swell together to inhibit stresses between the lens components and the cured adhesive.

Abstract: An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.

Abstract: Devices for moving blood within a patient, and methods of doing so. The devices can include a pump portion that includes an impeller and a housing around the impeller, as well as a fluid lumen. The impeller can be activated to cause rotation of the impeller and thereby move fluid within the fluid lumen.

Abstract: Multi-purpose electrodes for use during ablation are provided. The electrodes comprise a variable impedance region and a relatively constant impedance region. The relatively constant impedance region can be used for mapping, and both regions can be used for ablating. The mapping region can obtain low frequency electrophysiological signals during mapping, while both regions can conduct higher frequency ablation electrical signals to a patient during ablation.
