Abstract
Blood flow into vascular tissue is filtered in a manner that can also be useful for trapping particulates while allowing the flow of blood. Consistent with one or more embodiments, a filter apparatus includes a filter, an outer delivery sheath such as a catheter, and one or more shafts that are operable to manipulate the shape of the filter for positioning within vascular tissue. The filter conforms to various types of vascular tissue, and filters blood flow passing through openings in the vascular tissue. In some implementations, the filter is used to trap particulates that have been collected on the filter, and collapses to trap and draw the particulates into the outer delivery sheath.
