Benefits of technology

The patent is about a filter that can be used to remove emboli from blood vessels. The filter has a basket that is positioned upstream from the anchor members, which prevents the filter from clogging the blood vessel. The size of the filter basket can be controlled by adjusting the length of the filter members. This design allows for a larger volume of emboli to be removed without blocking the blood vessel. Overall, the invention provides a filter that can effectively remove emboli from blood without causing complications.

Problems solved by technology

This result has disadvantages when a significant mass of emboli 5 are retained.

Abstract

A blood filter device for placement in a blood vessel including a plurality of anchor members disposed radially and extending angularly about a first hub. A filter basket is preferably positioned upstream from the anchor members. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The filter basket is made up of a number of filter members configured to retain blood clots within the basket without completely blocking blood flow or applying additional force to vessel walls. Portions of the filter members may project radially outward to position the basket near the vessel centerline, but the filter basket preferably does not include hooks or anchors for anchoring the filter basket to the blood vessel.
