EMBOLIC PROTECTION DEVICE

摘要

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.

1. 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.
