摘要
A device and method for injecting liquid embolic agents utilizing a "plug and push" technique, The device/catheter has at least one side hole or an externally swellable region which creates a plug upstream of the distalmost portion of the catheter and thereby ameliorates the suboptimal outcomes associated with creating a plug upstream of a distal end hole via injecting embolic agents only at the distalmost portion of the catheter. The catheter can include a flow restricting structure to initially block flow of the liquid embolic agent out the distal end hole and direct flow of the liquid embolic agent through the one or more side holes.
