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:
Closed pouch comprising a wall defining an enclosed space containing carbon dioxide, and a pair of syringes contained within the enclosed space. The syringes are connected together by a syringe connector, and of the syringes contains a gas or gas mixture other than air, while the other contains a foamable liquid. Breakage of the syringe, connector and pumping of the syringes produces a foam useful in the treatment of varicose veins.

摘要:
The present invention provides a surgical clamp comprising a temperature sensitive shape memory material, the clamp capable of taking up a first form in which the clamp (6) is shaped to at least partially encircle a tubular structure (14); a second form shaped to substantially completely encircle the tubular structure (14) and constrict it, the clamp changing from the first form to the second form above the transition temperature of the shape memory material; and a third form derived from the first form by resilient deformation of the clamp in its first form. The present invention also provides applicators for delivering the clamps and kits comprising the clamps.
摘要:
Improved therapeutic sclerosing microfoams and methods and devices for making them are provided that have advantage in producing a consistent profile injectable foam with minimal input by the physician yet using high volume percentages of blood dispersible gases, thus avoiding use of potentially hazardous amounts of nitrogen.

摘要:
Apparatus, e.g. a syringe, for dispensing foam includes means for ensuring that only foam of adequate quality is dispensed. In use, the syringe may be filled from a pressurised canister which generates foam e.g. for therapeutic use in treating varicose veins. An initial quantity of foam dispensed from the canister may be of inadequate quality in which case it should not be used: the syringe includes means to ensure that this initial quantity of foam is diverted to a waste port or to an internal waste chamber e.g. located in the syringe plunger. Foam dispensed after the initial quantity of poor quality foam is stored in the main barrel of the syringe ready for administration to a patient in need of treatment.
