Abstract
An embolization system and methods for controlling solidification of embolic compositions comprising a first and a second embolic component that react with each other in vivo at a target site to form an embolic material, with the embolic components being dilutable in physiological fluids so that they do not form an embolic composition at a site that is not desired.
Claims22
An embolization system comprising:
- a catheter assembly comprising a first catheter and a distinct second catheter,
- a first liquid,
- a second liquid,
- an initiator,
- a co-initiator, with the initiator being disposed in one of the first liquid and the second liquid and the co-initiator being disposed in the other of the first liquid and the second liquid,
- a water soluble polymer disposed in at least one of the first liquid and the second liquid, the water soluble polymer comprising a plurality of functional groups,
- wherein the initiator and the co-initiator react to form a radical initiator upon mixing of the first and second liquids, and the radical initiator can initiate free radical polymerization of the functional groups to form a covalently crosslinked embolization material, and
- wherein the first catheter has an outer diameter ranging from 0.005 to 0.1 inches, the second catheter has an inner diameter ranging from 0.01 to 0.2 inches, and the first catheter is coaxially disposable inside the second catheter and slidably displaceable relative to the second catheter.
