As may be implemented with various aspects of the present disclosure, a mesh structure is coupled to inner and outer frames that operate with struts to apply pressure to the mesh. Such an approach may involve sealing the mesh around an opening, such as around one or more artery openings along an interior wall of vascular tissue (e.g., in an aortic arch). Accordingly, blood flow can be filtered in a manner that is useful for capturing particulates such as those resulting from surgical operations. In various implementations, the mesh, struts and frames are deployed using a catheter and shaft coupled to the frames. Such an approach can be implemented to apply a spring force from the shaft and through the frames for sealing the mesh.

Catheter-based apparatuses and methods

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.
