摘要:
A method of manufacturing microneedles is provided, the method includes (i) depositing a substance onto a first surface and (ii) forming a solid needle-like shape from the substance. The substance may be deposited in non-solid form and subsequently solidified. A method provides an array of such microneedles.
摘要:
A needleless device (10) for delivery of an agent through a biological barrier, the device comprising a microimplant (12) retaining layer (13) holding at least one microimplant for delivery through the biological barrier, a microimplant driving layer including means (21) for providing a motive force to the or each microimplant, and a guide layer having at least one guide channel associated with a microimplant through which the motive force is applied to the or each microimplant, wherein, in use, activation of the microimplant driving layer causes the or each microimplant to be driven away from the retaining layer through the biological barrier.
摘要:
A device (10) provides for transport of material across or into a biological barrier (2), the device includes a puncturing projection (11c) associated with a first portion of a substrate (1), the first portion of the substrate being movable between a first substrate position in which, in use, the puncturing projection is in puncturing contact with the biological barrier so as to form a flow path for said material across or into said biological barrier and a second substrate position in which, in use, the puncturing projection is at least partially retracted from the first position, wherein the substrate is resiliently deformable or displaceable from the first to the second substrate position by a biasing device associated with the substrate.
