Containers and methods for delivering vaso-occluding filaments and particles
First Claim
1. A kit for holding vaso-occluding particles comprising:
- a) a plurality of hydratable vaso-occluding particles; and
b) a container holding the hydratable vaso-occluding particles, said container having an ingress port adapted for fluid connection with a fluid source and an egress port adapted for fluid connection to a hub of a delivery catheter.

Abstract
This is directed to containers and methods for holding and delivering vaso-occluding materials such as hydrogel particles and filaments. The vaso-occlusive materials may be held in the container in a hydrated or unhydrated state. The container includes a fluid ingress port and a fluid egress port that are respectively fluidly connectable with a fluid source and a delivery catheter. The container further includes at least one chamber or passageway extending therebetween. The passageway may be straight, curved, spiral, helical, narrow or otherwise shaped. The chamber may also have sections of varying cross section such as a ramped section. The shapes of the passageways of the container help organize ejection of the vaso-occluding materials minimizing contamination and clumping. Methods for holding and introducing the materials are also provided.
