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.
Claims35
An embolic protection device for deployment within a patient's aorta comprising:
- an expandable structure comprising a filter mesh material, the structure having a compressed configuration wherein the structure is compressed to a small width for insertion into the patient's aorta and an expanded configuration, wherein the filter mesh expands to conform to or be held over the aortic vessels of the patient's aorta, wherein the filter mesh material is configured with an inner layer of filter mesh and an outer layer of filter mesh.
A method of providing embolic protection for sidebranch vessels connected to a patient's aorta comprising:
- introducing an embolic protection device into the patient's aorta, the embolic protection device comprising an expandable structure supporting a filter mesh material, the structure having a compressed configuration wherein the structure is compressed to a small width for insertion into the patient's aorta and an expanded configuration, wherein the filter mesh expands to conform to or be held over the aortic vessels of the patient's aorta such that the filter mesh material allows blood to enter the aortic vessels connected to the patient's aorta but prevents embolic material from entering the aortic vessels, wherein the filter mesh material is configured with an inner layer of filter mesh and an outer layer of filter mesh.
The method of claim 95, wherein introducing comprises releasing the compressed embolic protection device from a delivery tube which holds the embolic protection device in its compressed position.
