Patent ID: 8828042

Claim:
A device for retrieving an intravascular blood filter that has a plurality of retractable legs extending from a body, the device comprising: a catch tube comprising a catch extending therefrom that is configured to interact with at least one leg of the blood filter; and a sheath that defines a lumen that is configured to receive the blood filter therein when the legs of the filter are in a retracted state, wherein the sheath and the catch tube are rotatable relative to one another and are longitudinally translatable relative to one another such that the device is configured to permit adjustment of a rotational orientation of the catch relative to an opening into the lumen of the sheath so as to assist in introducing the filter into the lumen of the sheath; and wherein the device is configured to transition between a closed orientation in which at least a portion of the catch tube is positioned within the sheath and an open orientation in which the catch tube is spaced from the sheath, and wherein at least a position of the sheath is non-concentric with the catch tube when the device is in the closed orientation.
