Patent ID: 8057496

Claim:
A medical device to partially lyse and remove a thrombus from a blood vessel, the device comprising: a tubular outer sheath having a first lumen and a second lumen with each lumen having a distal portion extending to a distal end and a proximal portion extending from the distal portion to a proximal end; a wire guide placed into the proximal end of the first lumen for delivery to a patient through the proximal end of the first lumen, an injector mechanism causing a lysing agent to flow through the second lumen; and a wire basket slidably received within the first lumen to replace the wire guide, the wire basket having a proximal end and a distal tip and comprising a plurality of wires, the plurality of wires extending helically from the proximal end to the distal tip; a vacuum applied through the second lumen to remove the at least partially lysed thrombus; the device being operable in two modes including a first delivery mode and a second mixing mode; wherein the wire basket is sized and extended proximate to the thrombus in said delivery mode; wherein the wire basket is caused to engage the thrombus to transmit force thereto in the furtherance of at least partially lysing and removing the thrombus in said mixing mode; wherein the wire basket is coupled to a control member that may be used by an operator to manipulate the wire basket; wherein the wire basket is collapsible and fits within the first lumen.
