    摘要： A therapeutic foam for the treatment of, inter alia, varicose veins comprises a sclerosing solution foamed with a physiological gas such as carbon dioxide, oxygen or a mixture thereof. The foam has a nitrogen content of less than 0.8%. It may be generated using a pressurised canister system incorporating a fine mesh of micron dimensions through which the gas and sclerosing liquid are passed to make the foam. Alternatively, the foam may be generated by passing gas and solution between two syringes through a fine mesh. Techniques are described for minimising the amount of nitrogen in a canister or syringe based product. A technique for generating and delivering foam simultaneously using a syringe based device is also disclosed.

    摘要： A medical device having a housing (2) with a bore (3) and a lancet (1) slidably fitting in the bore. The lancet operates as a positive displacement piston. In a retracted position, in which the lancet is rearwardly displaced along the bore to define a fluid-containing space in the bore forwardly on the lancet tip, the fluid-containing space has a cross-section dimension to allow fluid to be retained therein by surface tension. The device has a seal (6) operable substantially to prevent flow of fluid from the fluid-containing space past the seal means on movement of the lancet. Displacement of the lancet between the puncture and retracted positions provides suction for drawing fluid into and along the fluid-containing space from the forward end of the bore, and/or pressure for expelling fluid from the fluid-containing space via the forward end of the bore. Also disclosed are methods for operating the device.
