  • Patent number: 7324851
    Abstract: A neurological control system for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a ?nervous system component.? The neurological control system generates neural modulation signals delivered to a nervous system component through one or more neuromodulators, comprising intracranial (IC) stimulating electrodes and other actuators, in accordance with treatment parameters. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors, each configured to sense a particular characteristic indicative of a neurological or psychiatric condition.

  • Patent number: 7314485
    Abstract: A mitral valve annulus reshaping device includes at least a portion that is formed of a biocompatible shape memory alloy SMA having a characteristic temperature, Af, that is preferably below body temperature. The device is constrained in an unstable martensite (UM) state while being introduced through a catheter that passes through the venous system and into the coronary sinus of the heart. The reshaping device is deployed adjacent to the mitral valve annulus of the heart as it is forced from the catheter. When released from the constraint of the catheter, the SMA of the device at least partially converts from the UM state to an austenitic state and attempts to change to a programmed shape that exerts a force on the adjacent tissue and modifies the shape of the annulus. The strain of the SMA can be varied when the device is within the coronary sinus.

  • Patent number: 7303526
    Abstract: A method and a device for improving cardiac function are provided. The device is packaged in a collapsed state in an end of a catheter. Portions of a frame construction of the device spring outwardly when the catheter is withdrawn from the device. Anchoring formations on the frame construction secure the frame construction to a myocardium of the heart. A membrane secured to the frame construction then forms a division between volumes of an endocardial cavity of the heart on opposing sides of the membrane.

  • Patent number: 7278739
    Abstract: An lens for correcting human vision, for example an IOL, contact lens or corneal inlay or onlay, that carries and interior phase or layer comprising a pattern of individual transparent adaptive displacement structures. In one embodiment, the displacement structures are actuated by a shape memory polymer (SMP) material or other polymer that is adjustable in shape in response to applied energy. The SMP can be designed to be selectively adjustable in volumetric dimension, modulus of elasticity and/or permeability. The adaptive optic means of the invention can be used to create highly localized surface corrections in the lens to correct higher order aberrations—which types of surfaces cannot be fabricated into and IOL and then implanted. The system of displacement structures also can provide spherical corrections in the lens.

  • Patent number: 7270676
    Abstract: An assembly and method for effecting the condition of a mitral valve annulus of a heart includes a guide wire configured to be fed into the coronary sinus of the heart, and a mitral valve annulus therapy device configured to be slidingly received on the guide wire and advanced into the coronary sinus of the heart on the guide wire. A guide tube may further be employed for guiding the device into the coronary sinus. An introducer which may be employed for pushing the device into or pulling device out of the heart has a mechanism for releasably locking to the device. This enables substitution of the device if needed. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed.

  • Patent number: 7264351
    Abstract: An lens for correcting human vision, for example an IOL, contact lens or corneal inlay or onlay, that carries and interior phase or layer comprising a pattern of individual transparent adaptive displacement structures. In the exemplary embodiments, the displacement structures are actuated by shape change polymer that adjusts a shape or other parameter in response to applied energy that in turn displaces a fluid media within the lens that actuates a flexible lens surface. The adaptive optic means of the invention can be used to create highly localized surface corrections in the lens to correct higher order aberrations-which types of surfaces cannot be fabricated into and IOL and then implanted. The system of displacement structures also can provide spherical corrections in the lens.

  • Patent number: 7261737
    Abstract: An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes a lens piston that alters the shape of a lens element of the lens to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. Forces applied to the haptic portion are concentrated by the lens piston to provide a greater dynamic range, and may be further augmented by the use of haptic pistons disposed in the haptic portion of the lens.

  • Patent number: 7247168
    Abstract: An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. Displacement of fluid to the actuator may either increase or reduce the degree of deflection imposed on the lens element by the actuator.

  • Patent number: 7198595
    Abstract: Cardiac apparatus and methods of using such cardiac apparatus are described. In one embodiment, a cardiac apparatus includes a covering that is configured to at least partially encircle a heart with a first portion of the covering adjacent to a second portion of the covering. The cardiac apparatus also includes an electroactive polymer actuator. A first end of the electroactive polymer actuator is coupled to the first portion of the covering, and a second end of the electroactive polymer actuator is coupled to the second portion of the covering. The second end of the electroactive polymer actuator is oriented such that, upon actuation of the electroactive polymer actuator, the second end of the electroactive polymer actuator extends away from the first end of the electroactive polymer actuator to move the second portion of the covering towards the first portion of the covering.
