Publication number: 20050143713Abstract: Microneedle arrays, methods of manufacturing microneedles and methods of using microneedle arrays. The microneedles in the microneedle arrays may be in the form of tapered structures that include at least one channel formed in the outside surface of each microneedle. The microneedles may have bases that are elongated in one direction. The channels in microneedles with elongated bases may extend from one of the ends of the elongated bases towards the tips of the microneedles. The channels formed along the sides of the microneedles may optionally be terminated short of the tips of the microneedles. The microneedle arrays may also include conduit structures formed on the surface of the substrate on which the microneedle array is located. The channels in the microneedles may be in fluid communication with the conduit structures. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue.Type: ApplicationFiled: March 3, 2005Publication date: June 30, 2005Inventors: Michael Delmore, Patrick Fleming, Douglas Huntley, Jamieson Keister, Cristina Thomas, Richard Ferber

Patent number: 6746567Abstract: A film or tape has one of its major surfaces defined by microstructured features including a plurality of channels defined by spaced apart protrusions. The microstructured film is able to acquire liquids and to control the directional transport of such liquids for subsequent removal therefrom. The transport can be passive or active (i.e., caused or enhanced by an applied potential). The inventive microstructured films and tapes have applications in laminate floor assemblies (for spill removal) and industrial articles such as computer keyboards and other devices and assemblies that benefit from fluid removal. The invention also has application in evaporative and condensation applications. In one embodiment, at least one cross-channel is formed on the microstructured surface to join adjacent channels for liquid flow therebetween.Type: GrantFiled: December 20, 2002Date of Patent: June 8, 2004Assignee: 3M Innovative Properties CompanyInventors: Raymond P. Johnston, Sara B. Mortenson, Douglas A. Huntley, Stephanie B. Castiglione

Patent number: 6649249Abstract: A receptor medium with a sheet having a random microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, electrically, thermally, or magnetically modifiable materials, and combinations thereof. The random microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire' effects. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire' effects. Methods of making and using the inkjet receptor medium are also disclosed.Type: GrantFiled: May 31, 2000Date of Patent: November 18, 2003Assignee: 3M Innovative Properties CompanyInventors: Lori P. Engle, Robert T. Fehr, Patrick R. Fleming, Paul D. Graham, Douglas A. Huntley, Verna J. LeMire, Jeffrey L. Solomon, Todd R. Williams, Caroline M. Ylitalo
