摘要： An interface needle (12) is used for connecting a syringe (14) to a catheter (10) to create a blunt interface between two or more liquids being delivered through the catheter (10). The interface needle (12) is particularly useful for creating a blunt interface between a bio-compatible solvent and a liquid embolic composition which is delivered to the body for treatment of various conditions including aneurysms. A system for liquid delivery with a blunt liquid interface includes a catheter (10) or other cannula, an interface needle (12), and a syringe (14). The interface needle (12) includes a tube (36) extending from a distal end which delivers liquid to a lumen of the catheter (10) bypassing a reservoir (36) in the catheter hub (28) to create the blunt liquid interface. One embodiment of the interface needle (12) controls an injection pressure of high viscosity liquids.

摘要： A threaded syringe (10) provides a mechanism by which a clinician can deliver a viscous fluid through a relatively small lumen and can obtain tactile or audible feedback of delivery. The threaded syringe (10) allows for delivery of more viscous fluids with less forces and/or allows for more controlled delivery. The syringe includes a syringe barrel (12) and a sliding member (14) positioned on the proximal end of the syringe barrel (12). The sliding member (14) has a first threaded hole (28) and a second hole (30). The sliding member (14) is sliding on the syringe barrel (12) between a first position at which the first threaded hole (28) is aligned with the syringe barrel (12) for precise delivery of a material from the syringe and a second position at which the second hole (30) is aligned with the syringe barrel (12) for filling of the syringe or to stop bleed out.
