Patent number: 10646703Abstract: This invention relates to a device that uses microneedles to create pores in the skin of a subject and delivers the drug transdermally by inserting it into the pore as a solid or semi-solid mass alongside each needle. The device is sufficiently flexible to allow relative movement of the needle and the drug mass apart from one another. Preferably a chamber holding the drug mass comprises a relatively rigid wall to ensure that the drug remains aligned close to the needle, while an adjacent chamber holding the needle comprises a relatively flexible wall to allow lateral movement of the needle as the drug is inserted alongside it.Type: GrantFiled: April 23, 2014Date of Patent: May 12, 2020Assignee: NDM Technologies LimitedInventor: Dewan Fazlul Hoque Chowdhury

Patent number: 10576040Abstract: Irregular, angular particles are produced by a manufacturing method that comprises forming a film on a substrate and then stretching the substrate along one or more axes to fracture the film into particle structures. The substrate may be moved continuously along a production line as the film is formed and may be stretched by accelerating that movement. The substrate may comprise a surface with elevated patterns to control the fracturing of the film. The particles are particularly suitable for the transdermal delivery of a biologically active substance into the body of a patient.Type: GrantFiled: January 12, 2018Date of Patent: March 3, 2020Assignee: NDM Technologies LimitedInventor: Dewan Fazlul Hoque Chowdhury

Patent number: 10239236Abstract: Microneedle devices have projections that are generally sharp and elongated and designed to disrupt the upper layer of the skin, cause micro-indentations, or pierce the skin. High density arrays are produced using micro-fabrication or micro-molding techniques. The assembly of individual needles does not lend itself to the production of high density arrays. A method of forming microneedle arrays is disclosed which comprises attaching a plurality of microneedles to a substrate, and building up a 2-dimensional microneedle array by wrapping layers of the substrate around a core or folding the layers repeatedly back upon themselves. The arrays are capable of needle densities with a pitch within the range of needle radius plus several micrometers to millimeters.Type: GrantFiled: August 18, 2014Date of Patent: March 26, 2019Assignee: NDM Technologies LimitedInventor: Dewan Fazlul Hoque Chowdhury
