  • Delivery device and method
    Patent number: 9549746
    Abstract: A microprotrusion array for use in transport of a material across a biological barrier, wherein said array comprises a plurality of microprotusions composed of a swellable polymer composition.
    Type: Grant
    Filed: September 29, 2008
    Date of Patent: January 24, 2017
    Assignee: THE QUEEN'S UNIVERSITY OF BELFAST

  • Apparatus for use in the prophylaxis or treatment of tissue
    Patent number: 8545497
    Abstract: Apparatus (20) for carrying out a prophylactic or treatment procedure on tissue comprises a device (21) having a chamber (22) and at least one active element such as an electrode (23) within the chamber (22). The chamber (22) has an opening (26) through which tissue is drawn into the chamber (22). Means for drawing the tissue into the chamber may comprise a vacuum lumen with vacuum orifices (25) in the chamber (22). Treatment such as electroporation may be applied to tissue in the chamber (22).
    Type: Grant

  • Wet etch processing
    Patent number: 7651946
    Abstract: A method of wet etching produces high-precision microneedle arrays for use in medical applications. The method achieves precise process control over microneedle fabrication, at single wafer or batch-level, using wet etching of silicon with potassium hydroxide (KOH) solution by accurately identifying the etch time endpoint. Hence, microneedles of an exactly required height, shape, sharpness and surface quality are achieved. The outcome is a reliable, reproducible, robust and relatively inexpensive microneedle fabrication process. Microneedles formed by KOH wet etching have extremely smooth surfaces and exhibit superior mechanical and structural robustness to their dry etched counterparts. These properties afford extra reliability to such silicon microneedles, making them ideal for medical applications. The needles can also be hollowed. Wet etched silicon microneedles can then be employed as masters to replicate the improved surface and structural properties in other materials (such as polymers) by moulding.
