Abstract
A medical device for removing a thrombus from a blood vessel and a process thereof is presented. The device includes an outer sheath with a plurality of lumens. A wire guide inserted through one of the lumens is used to place the device proximate to a thrombus. A chemical lysing agent is used to at least partially lyse the thrombus. A wire basket extended through the first lumen proximate to the thrombus is translated back and forth to generate a force that may be transmitted to the partially lysed thrombus assisting in the formation of smaller fragments. A vacuum coupled to the distal end of the second lumen is used to remove the lysed thrombus fragments.
