  • Patent number: 10278808
    Abstract: This document discusses, among other things, a system for translocating a multilayer patch. The system includes a support structure having a contact surface for bonding to the patch. The support structure has a shape configured to support the patch following separation of the patch from a surrounding tissue.
    Type: Grant
    Filed: September 29, 2014
    Date of Patent: May 7, 2019
    Assignees: Emory University, University of Minnesota

  • Patent number: 8083751
    Abstract: A remotely controllable system and method for positioning and operating a scleral depressor. A track is positioned to encircle at least a portion of the eye. One or more independent thrusters, or actuators, are radially positionable about the eye. An actuator is selectively deployable and selectively retractable by remote control. Thrusters may be mechanically operated and include pneumatic, hydraulic, electrical, chemical or other power supply forces. Remote control is provided by hand-operated controls, foot-operated switches or voice-operated control. A light source is positioned about at least a portion of the eye to provide transcleral illumination.

  • Patent number: 7988685
    Abstract: The invention provides hydrogel compositions, components, and hydrogel-actuated or mediated devices, and methods for the incorporation of hydrogel microscale components in microscale devices and systems. The methods and devices result in active microvalves that are useful in microfluidic applications, including analyte sensing, in process chemical and fermentation stream monitoring, and drug delivery. In particular, the devices are useful for controlled drug delivery either in response to a pre-determined stimulus or for pulsatile delivery.
