Systems and methods for assembling a plurality of tissue grafts are provided. A method includes applying a magnetic coating over a surface of a donor site and harvesting the plurality of micro tissue grafts from the donor site, so that an upper surface of each of the plurality of micro tissue grafts contains the coating. The method also includes arranging a magnet over the magnetic coating to induce the plurality of micro tissue grafts to organize in a desired orientation, forming a tissue construct containing the plurality of micro tissue grafts arranged in the desired orientation, and applying the tissue construct to a recipient site.

Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm, using a mechanical apparatus, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes formed can be well-tolerated by the skin, and can exhibit shorter healing times and less swelling than conventional resurfacing procedures. The apparatus includes one or more needles adapted to remove a small portion of tissue when inserted into and withdrawn from the skin. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The exemplary method and apparatus can produce cosmetic effects such as increases in collagen content, epidermal thickness, and dermal/epidermal junction undulations in the skin.

A needling device may be used for needling of a subject's skin, and a drug applicator device may be used for applying a drug to a subject's skin. For example, a needling device may be applied to a subject's skin for hair growth applications, or may be used for wrinkle, scar, or tattoo removal. A drug applicator device may be used for multiple drug application purposes such as applying a hair growth compound to the skin of a subject.

The present invention discloses an advance in enhanced stability, enhanced solubility, and enhanced uniqueness towards a micro needling stamper device by proposing an improved process by presenting a technique where skin care products are delivered by way of a needling device is presented. The device has a suction that operates in the casing of the needles. When the stamping of the microneedles occurs, this suction feature lift the skin from it's a regular lying surface. The suction feature promotes blood circulation which will promote cell repair and aide in regeneration. This vacuum like suction separates different layers of tissues, thus microtrauma from the needles is more confined to the layer desired; the epidermis. This also triggers an inflammatory response flooding the area with white blood cells, platelets, and other healing aids for the re-generation process.

The present invention relates to a microneedle system (MNS) for intradermally delivering solutions or formulations. The invention relates to a microneedle system, comprising a cover element (1), an active substance container (2), a frame (3), a microneedle array (MNA) (4) and a base plate (5), wherein the microneedle array (MNA) (4) is connected to the frame (3), and the base plate (5) has an opening for receiving the microneedle array (4), the cover element (1) and the base plate (5) are movably connected to one another, the base plate (5) is joined to a surgical tape (6), and the frame (3) and the base plate (5) can be linearly displaced with respect to one another. The MNS according to the invention is suitable for intradermally administering medicinal drugs, active substances, pharmaceutical or cosmetic compositions or other substances to an individual, and preferably to a patient, over an extended period.

Exemplary embodiments of method and apparatus are provided for damaging and/or removing portions of subcutaneous fatty tissue while leaving the overlying dermal layer of the skin substantially undamaged. One or more hollow needles can be provided that include an arrangement within the lumen configured to retain or damage portions of fatty tissue that enter the lumen. Properties of the needle can be selected such that the needle can be inserted into skin and pass through the dermal layer, allowing fatty tissue to enter the distal portion of the lumen as it is advanced further, and then leaving the dermis undamaged when withdrawn. Such exemplary apparatus can include a plurality of such needles, a reciprocating arrangement to mechanically advance and withdraw the one or more needles, and/or a vibrating arrangement.

A device and method for treating disease involves inserting a scope into a patient's body, the scope having a light source, a camera and a cartridge connected thereto. The cartridge has two chambers separated by membrane, a first one of the chambers containing a virus, and a second one of the chambers being connected to a plurality of microneedles configured for extending into the patient's tissue upon insertion of the scope. Cells from the patient are removed via suction from the microneedles and are deposited in the second chambers. The membrane is then broken to mix the virus with the cells to infect the cells, and the infected cells are then transported back into the patient to treat the disease.

A recombinant coronavirus vaccine is provided. Methods of making and delivering the coronavirus vaccine also are provided. A microneedle array is provided, along with methods of making and using the microneedle array.

A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

The present invention relates to microprojection arrays for the delivery of vaccines, in particular the use of polymer high density microprojection arrays for the delivery of vaccines to patients in which the dose of the vaccine delivered may be less than the dose of vaccine delivered by intramuscular injection while providing equal or superior immunogenicity.
