(54) Title: SYRINGE FOR ADMINISTERING FOAM (57) : Syringes which are suitable for dispensing and injecting medical foams for scle- 37 rotherapy are described and claimed. The syringes of the invention comprise a syringe barrel having 36 _ 38 a nozzle and a bore to receive a syringe plunger; a syringe plunger defined by a front end and a rear 35 33 end connected by a tubular walls and having an internal hollow duct between the front end and the rear end, and through which foam can flow; and an injectate chamber formed by insertion of the front end of the plunger into the barrel. The syringes comprise a flow-disruptor arranged to modify 28 the flow of foam as it enters the injectate chamber. In certain embodiments the syringes comprise 31 waste chambers which capture and retain poor quality foam. The syringes are particularly useful for 29 dispensing foams made with little or no nitrogen content and are configured to reduce the risk of air contamination during dispensing the foam. Kits comprising the syringes together with a suitable .1L„ source of foam and methods of dispensing foam form further aspects of the invention. 2 30 FIG. 2 [Continued on next page] WO 2018/020367 Al MIDEDIM011111 11111111E101111010101111101100H11EM0IS Published: with international search report (Art. 21(3)) before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h))
