Abstract: The present invention relates to a tip for use with delivery devices, particularly for use in implanting retinal implants into the retinal space of an eye. The tip includes a flexible envelope and an internal sliding member. Further, the invention relates to an inserter attachment and a delivery device including said tip.

Abstract: A thermal compensation system is provided for a liquid-filled inflexible chamber of a device. The chamber has at least one exposed, at least partially transparent surface allowing an outside observer to observe at least one liquid and comprises a mechanism accommodating thermal expansion and/or contraction of the liquids. The mechanism is disposed so as to be substantially invisible to the observer.

Abstract: An indication device is provided. The indication device includes an elongated fluid chamber containing at least one electrically conductive liquid driven by a pump for conductive liquids and an immiscible, relatively non-conductive fluid. At least one segment of at least one fluid is used as an indicator. This segment is driven by the pump along adjacent indices of an indicator visible to an observer using a meniscus location sensor and a feedback controller so as to e.g indicate a quantity to the observer.

Abstract: An indication device is provided which has an electrically conductive fluid driven by an MHD pump. The fluid has an indicator surface driven adjacent indices of an indicator so as to indicate a quantity. A position of the indicator surface is sensed and controlled to ensure accurate indication of the quantity. Optionally, the quantity indicated is time.

Abstract: A drive system for energizing a device that includes a bellows actuated drive. The bellows actuated drive provides linear forward and backward movement by fluid expansion and contraction of a fluid within a reservoir according to a temperature differential while the reservoir is in fluid contact with the bellows. In one variant, two bellows are configured in a V shaped conformation. Various devices are driven using the drive system of the current invention and include a timepiece, a medical device, an implantable medical device, a cardiac rhythm management device, a hearing aid, a medical micro-injector, a sensor, and a biometric transmitter.
