Abstract: A catheter used for treatment of complex vasculature, such as a bifurcated aneurysm, is provided with an inflatable balloon at a distal portion thereof. The shape, location and material of the inflatable balloon are selected such that when inflated, the balloon conforms to the shape of the complex vasculature, or at least a portion thereof, without appreciably deforming the vessel walls. In this manner, the balloon can be used to control flow in the vasculature, for example occluding a selected branch of the vasculature during introduction of material in order concentrate the material and minimize its disbursement by blood flow.

Abstract: This invention is directed to methods for treating aneurysms wherein the aneurysmal sac is filled with a non-particulate agent or plurality of such agents and/or with a fluid composition which solidifies in situ. Filling of the aneurysmal sac employs sufficient amount of the non-particulate agent or plurality of such agents and/or the fluid composition to inhibit blood flow into the aneurysm sac. In addition, the methods of this invention also provide for non-endogenous isolation of the parent artery proximal and distal to the aneurysmal sac from systemic blood flow of the treated mammal. The combination of these features provides for treatment of the aneurysmal sac while, at the same time, inhibiting aneurysm formation and/or regrowth in the diseased portions of the arterial wall proximal and distal to the treated aneurysm.

Abstract: Disclosed are novel techniques for embolizing blood vessels which are particularly suited for treating vascular lesions via catheter delivery of an embolic composition.

Abstract: Disclosed are novel methods for embolizing blood vessels comprising delivering, via a catheter, an embolic composition comprising a biocompatible polymer, a biocompatible water insoluble contrast agent, and a biocompatible solvent. In one embodiment, the method is conducted during a single surgical procedure whereby a flow-arresting device is positioned and activated at the vascular site to be embolized, the embolic composition is injected, and the flow-arresting device is deactivated. In another embodiment, the method is conducted during a single surgical procedure whereby two embolic compositions, situated adjacent to one another, are injected at the vascular site to be embolized.

Abstract: A catheter and system for delivering viscous fluid, under high pressures, into the vasculature of a patient includes a catheter body having a proximal end and a distal end, a reinforcing member surrounding at least a portion of the proximal end, and a compression fitting surrounding the reinforcing member for holding the proximal end of the catheter body. A strain relief element shrouds a portion of the proximal end to prevent kinking of the catheter body. Accordingly, the reinforcing member, the compression fitting and the strain relief element cooperate to hold the catheter body in a luer fitting and to prevent the proximal end of the catheter body from kinking under bending, and to prevent leakage or bursting under pressure.
