A dry powder inhaler having a housing, at least one single dose storage chamber able to contain a single unit dose, a discharge path adjacent the storage chamber, and a flexible and bendable seal plate closing the discharge path. When an air flow under pressure is applied to the top of the dose, the top seal is broken and the dose is driven against the seal plate which deflects away, allowing the powder of the dose to be driven into and along the discharge path. The air flow causes the seal plate (in the discharge path) to vibrate, which acts to break up the dose into particles of preferred size, as the dose is carried along with the air flow and delivered to a patient.

A method of making a barbed suture by varying the blade geometry and/or the movement of the blade when cutting a suture. The method can also be accomplished with a cutting device to create a plurality of barbs on the exterior of surgical suture. The barbs produced using the method with the cutting device can be the same or random configurations.

The invention is a solid state microanemometer and a method of making thereof. Specifically, the invention relates to a microanemometer including an electrically conductive resistor in the form of a semiconductor wafer doped with an impurity having an upper surface, a lower surface having a peripheral edge; a substrate bonded to the semiconductor wafer having an upper surface, a cavity having a peripheral edge and a peripheral margin defined on the upper surface and bounded by the peripheral edge of the cavity wherein the lower surface of the semiconductor wafer rests on and is supported by at least part of the peripheral edge of the cavity such that the semiconductor wafer is over the cavity; and a means for electrically connecting the resistor to a current source. The microanemometer also includes a plurality of metal conductors in contact with the resistor. The semiconductor wafer has sloped sidewalls and the metal conductors are placed on sloped sidewalls of the wafer to effectively increase available active area of the resistor.
