Abstract
The embolic protection device (10) has an expandable tubular structure supporting a filter mesh material (12). The embolic protection device is compressed to a small diameter for insertion into a patient's aorta, then expanded within the aorta with the filter mesh material positioned to allow blood to enter sidebranch vessels connected to the aorta and to prevent embolic material from entering the sidebranch vessels. The filter mesh material may be configured with waves or undulations (26) for increased surface area and/or with two layers of mesh material to provide additional protection against embolization and to prevent inadvertent occlusion of the sidebranch vessels.
Claims27
An embolic protection device for deployment within a patient's aorta comprising:
- a tubular mesh structure configured to be compressed to a small diameter in a delivery tube for insertion into the patient's aorta and to expand to a larger size when released from the delivery tube within the patient's aorta such that one side of tubular mesh structure covers ostia of sidebranch vessels connected to the patient's aorta and allow blood to enter the sidebranch vessels and prevents embolic material from entering the sidebranch vessels, wherein the tubular mesh structure is configured to conform to the walls of the aorta and ostia of the sidebranch vessels so that the tubular mesh structure will not interfere with performing cardiac surgery or catheter-based interventional cardiology or electrophysiology procedures, wherein said tubular mesh structure has a length sufficient to cover all ostia of sidebranch vessels connected to the patient's aorta in the area of the aortic arch.
An embolic protection device for deployment within a patient's aorta comprising:
- a tubular mesh structure configured to be compressed to a small diameter in a delivery tube for insertion into the patient's aorta and to expand to a larger size when released from the delivery tube within the patient's aorta such that one side of tubular mesh structure covers and conforms to the ostia of sidebranch vessels connected to the patient's aorta with an open upstream end and an open downstream end to allow passage of a catheter therethrough and allow blood to enter the sidebranch vessels and prevents embolic material from entering the sidebranch vessels;
- and
- a handle or cannula attached to the tubular mesh structure for insertion through peripheral vasculature or an aortotomy.
