摘要： Disclosed are accommodating intraocular lenses for implantation in an eye having an optical axis. In certain embodiments, an intraocular lens includes an anterior optic, a posterior optic, and a support structure configured to move the optics relative to each other along an optical axis between an accommodated state and an unaccommodated state. In certain embodiments, at least a portion of the support structure can be modified in situ to alter reaction forces between the support structure and at least one structure of the eye. In certain embodiments, a refractive property of one of the anterior or posterior optics can be modified in situ while leaving the refractive properties of the remaining one of the anterior or posterior optics substantially unaffected. Additional embodiments and methods are also disclosed.

摘要： A device to provide body fluid flow control in the form of a valve to be located within a duct or passageway. The device is controlled through pressure above a preselected threshold. Bulk resilience about a passageway in a valve body provides the mechanism for controlled flow. One-way valve operation may be provided through a flap or through a pressure differential on the valve body depending upon the direction of flow. A frame structure positioned within a resilient seal includes longitudinally elongated elements which may be of spring material, malleable material or heat recoverable material so as to accomplish an initial insertion state and an expanded anchoring state. A valve support transitions between the resilient seal portion and the valve body to insure that the states do not change the threshold opening pressure. Insertion devices may be employed to position and actuate a change of state of the frame in the body duct or passageway.

摘要： An accommodating intraocular lens comprises first and second viewing elements interconnected by a biasing member such that the viewing elements are relatively movable in response to the ciliary muscle of the eye. The viewing elements are positioned further apart when in the accommodated position than when in the unaccommodated position. The viewing elements are biased toward the accommodated position. The biasing member relatively moves the viewing elements along an optical axis of the intraocular lens. The biasing member has a standard bias force characteristic of between about 50 mg and about 750 mg.

摘要： The present invention provides a method for exchanging catheters while containing emboli within a blood vessel such as a saphenous vein graft, coronary artery, carotid artery, or other similar vessels. A guidewire is inserted through the vasculature of a patient until it reaches a desired treatment site. A therapy catheter is then inserted over the guidewire until the distal end of the therapy catheter reaches the treatment site. The guidewire has a distally mounted balloon which is inflated to occlude the blood vessel. Then, the therapy catheter provides means for treating the vessel at the treatment site. After treatment, the therapy catheter is removed from the guidewire and exchanged with an aspiration catheter which rides over the guidewire until the distal end of the aspiration catheter reaches the treatment site. The aspiration catheter applies negative pressure to remove any emboli formed by the treatment procedure.

摘要： A method for delivering a drug to the site of an intravascular occlusion. A guidewire having a balloon at one end is advanced across the occlusion using a guide catheter, and the balloon is inflated distal to the occlusion to occlude the blood vessel. An aspiration catheter is then inserted into the vessel with its tip less than about 5 mm from the surface of the balloon, and a drug is delivered which flows distal to proximal to treat the occlusion.
