Patent number: 7763203Abstract: A method for manufacturing microneedle structures is disclosed using soft lithography and photolithography, in which micromold structures made of a photoresist material or PDMS are created. The micromold manufacturing occurs quite quickly, using inexpensive materials and processes. Once the molds are available, using moldable materials such as polymers, microneedle arrays can be molded or embossed in relatively fast procedures. In some cases a sacrificial layer is provided between the forming micromold and its substrate layer, for ease of separation. The microneedles themselves can be solid projections, hollow “microtubes,” or shallow “microcups.” Electrodes can be formed on the microneedle arrays, including individual electrodes per hollow microtube.Type: GrantFiled: December 3, 2003Date of Patent: July 27, 2010Assignee: Corium International, Inc.Inventors: Francisco Arias, Faiz Feisal Sherman, Grover David Owens

Patent number: 7578954Abstract: A method is provided for manufacturing microstructures of the type which contain a substrate and an array of protruding microelements with through-holes, which are used in penetrating layers of skin. The microelements are embossed or pressed into an initial substrate structure, which in some embodiments is formed from extruded polymeric material, and in some cases from two layers of polymer that are co-extruded. The through-holes are formed from filled through-cylinders of a second material that is removed after the embossing or pressing step; in other instances, the through-holes are left hollow during the embossing or pressing step.Type: GrantFiled: February 24, 2003Date of Patent: August 25, 2009Assignee: Corium International, Inc.Inventors: Vladimir Gartstein, Faiz Feisal Sherman

Patent number: 7572405Abstract: A method is provided for constructing microstructures that can penetrate skin layers, in which the microelements are formed during a molding process while fluidic jets produce openings in the microelements. The structures used in the molding process are formed by tooling that creates the shapes of the microelements in a material deposition step, and also creates the sizes and shapes of the openings that will be formed by the fluidic jets.Type: GrantFiled: May 25, 2004Date of Patent: August 11, 2009Assignee: Corium International Inc.Inventors: Faiz Feisal Sherman, Vladimir Gartstein

Patent number: 7416541Abstract: Improved microneedle arrays are provided having a sufficiently large separation distance between each of the individual microneedles to ensure penetration of the skin while having a sufficiently small separation distance to provide high transdermal transport rates. A very useful range of separation distances between microneedles is in the range of 100-300 microns, and more preferably in the range of 100-200 microns. The outer diameter and microneedle length is also very important, and in combination with the separation distance will be crucial as to whether or not the microneedles will actually penetrate the stratum corneum of skin. For circular microneedles, a useful outer diameter range is from 20-100 microns, and more preferably in the range of 20-50 microns.Type: GrantFiled: May 3, 2005Date of Patent: August 26, 2008Assignee: Corium International, Inc.Inventors: Vadim Vladimirovich Yuzhakov, Faiz Feisal Sherman, Grover David Owens, Vladimir Gartstein

Patent number: 7131987Abstract: An improved method is provided to enhance skin appearance and health, in which skin is cleaned (or exfoliated) and conditioned by use of microelements affixed to a base element or hand-held patch. For the microstructure used in the improved method, the dimensions of the microelements are controlled so as to remove a certain number of layers of skin cells and to accumulate and retain those skin cells, along with other foreign substances, into areas between the microelements. In another embodiment of the improved method, a conditioning compound or therapeutic active can be applied to the exfoliated skin to enhance the skin. Moreover, the amount of skin cells accumulated using the improved method represents a self-limiting maximum quantity that cannot be substantially exceeded regardless of the number of attempts by a user to re-use the microstructure apparatus associated with the improved method.Type: GrantFiled: May 24, 2002Date of Patent: November 7, 2006Assignee: Corium International, Inc.Inventors: Faiz Feisal Sherman, Vladimir Gartstein

Patent number: 7108681Abstract: An improved method and apparatus is provided as a system to deliver a composition, preferably a medical or pharmaceutical composition or active, through the stratum corneum of skin, without introducing bleeding or damage to tissue, and absent pain or other trauma. The dimensions and shapes of the microelements are controlled so as to control the penetration depth into the skin. The microelements can be “hollow” such that passageways are created therethrough to allow the composition to flow from a chamber, through the microelements, and into the skin. Alternatively, the microelements can be “solid,” and the composition is applied directly to the skin just before or just after the microelements are applied to the skin surface to create the openings in the stratum corneum.Type: GrantFiled: September 14, 2001Date of Patent: September 19, 2006Assignee: Corium International, Inc.Inventors: Vladimir Gartstein, Faiz Feisal Sherman
