Abstract
An embolic protection device may include an inflatable embolic balloon with one or more embolic capture elements located at or around its outer surface. The balloon may be inflatable so as to move the one or more embolic capture elements near or against the wall of a vessel. Emboli, and particularly emboli that are relatively more diffuse, softer, more friable, contain more inflammatory cells, and/or may lack fibrous caps, are captured or stopped by the one or more embolic capture elements as blood passes through the one or more embolic capture elements.
Claims22
An embolic protection device, comprising:
- an elongated catheter body;
- an embolic balloon located at a distal portion of the elongated catheter body;
- and,
- one or more embolic capture elements that are each positioned around the embolic balloon;
- wherein the one or more embolic capture elements extend outward from the embolic balloon when the embolic balloon is at an inflated configuration;
- and,
- wherein the one or more embolic capture elements each comprise one or more wires coiled at least once around an outside of the embolic balloon.
An embolic protection device, comprising:
- an elongated catheter body;
- an embolic balloon located at a distal portion of the elongated catheter body;
- the embolic balloon having an inflated state and a deflated state;
- and,
- one or more embolic capture elements that are each positioned around the embolic balloon;
- wherein the one or more embolic capture elements extend radially away from the embolic balloon when the embolic balloon is in the inflated state;
- and,
- wherein the one or more embolic capture elements each comprise one or more wires coiled at least once around an outside of the embolic balloon.
An embolic protection device, comprising:
- an elongated catheter body;
- an embolic balloon located at a distal portion of the elongated catheter body;
- and,
- one or more embolic capture means for capturing embolic material;
- wherein each are each positioned around the embolic balloon and comprise one or more wires coiled at least once around an outside of the embolic balloon.
A method of using an embolic protection device, comprising:
- advancing a distal portion of an elongated catheter body near a treatment location;
- inflating an embolic balloon located at a distal portion of the elongated catheter body such that one or more embolic capture elements extend radially from the embolic balloon;
- wherein the one or more embolic capture elements each comprise one or more wires coiled at least once around an outside of the embolic balloon;
- and,
- performing a treatment at the treatment location such that embolic material is captured by the one or more embolic capture elements.
