Abstract: A method for calibrating and executing a rehabilitation exercise for a stroke-affected limb of a stroke patient is disclosed, the method comprising the steps of providing a haptic device for an able limb of the stroke patient to manipulate to perform a calibration action to result in a first position of the haptic device, and providing the haptic device for the stroke-affected limb to manipulate to perform the calibration action to result in a second position of the haptic device. The method further comprises the steps of moving the haptic device coupled with the stroke-affected limb from the second position towards the first position until a predetermined counterforce is detected, indicating an extreme position for the stroke-affected limb using the haptic device, and calibrating the haptic device with the extreme position such that during the rehabilitation exercise, the haptic device is prevented from moving beyond the extreme position.

Abstract: Vascular devices and methods for addressing pathologies in the hemiarch of the aorta are provided. The device includes a main body and a secondary body. The main body has ends that are designed to be connected to corresponding ends of the native blood vessel. The secondary body has a free end and a fixed end that is engaged with an inner surface of the main body. The vascular device is movable from a retracted configuration, in which the secondary body is at least partially contained within the main body and the free end is on a proximal side of the fixed end, to an extended configuration, in which the secondary body is extended distally from the main body and the free end is on a distal side of the fixed end to address defects in the aorta downstream of the hemiarch.

Abstract: An accommodating intraocular lens (IOL) device adapted for implantation in the lens capsule of a subject's eye. The IOL device includes an anterior refractive optical element and a membrane coupled to the refractive optical element. The anterior refractive optical element and the membrane define an enclosed cavity configured to contain a fluid.

The second elution rate is faster than the first elution rate. The hollow strut deforms from the first configuration to the second configuration upon application of an applied pressure above a predetermined threshold.
