  • Polymer microneedles
    Patent number: 6924087
    Abstract: A method for producing microneedles. The method including disposing a first layer of a radiation sensitive polymer on to a working surface and selectively irradiating the first layer such that the first layer has at least one irradiated region and at least one non-irradiated region. The method also including developing the first layer so as to selectively remove one of the at least one irradiated region and the at least one non-irradiated region such that, at least part of at least one remaining region at least partially defines a form of at least part of a microneedle structure. A microneedle structure including a plurality of microneedles at least partially formed from a radiation sensitive polymer.
    Type: Grant

    Date of Patent: August 2, 2005
    Assignee: Nano Pass Technologies Ltd.
    Inventors: Yehoshua Yeshurun, Meir Hefetz, Erwin Berenschot, Meint de Boer, Dominique Maria Altpeter, Garrit Boom
