DEVICE AND METHOD FOR CONTROLLING INJECTION OF LIQUID EMBOLIC COMPOSITION
First Claim
1. A liquid embolic delivery system comprising:
- a catheter having a lumen for delivery of a liquid embolic composition to a cavity;
a containment member positioned at a distal end of the catheter, the containment member shaped to trap the liquid embolic composition delivered through the lumen of the catheter; and
a detachment mechanism for completely detaching the containment member from the catheter after solidification of the liquid embolic composition to allow separation of the catheter from a mass of solidified embolic composition.

Abstract
A liquid embolic delivery system is provided for trapping an injected liquid embolic composition to prevent the liquid embolic from solidifying or otherwise passing outside of an embolization area. The delivery system includes a catheter for delivery of a liquid embolic composition and a containment member positioned at a distal end of the catheter which is shaped to trap the liquid embolic composition delivered through the lumen of the catheter. The containment member is formed as a brush, nest, sponge, swab, flexible sack, or other shape into and around which the liquid embolic composition is injected. The liquid embolic composition is trapped or meshes with the containment member during solidification containing the liquid embolic and preventing the embolic composition from passing into the blood stream.
