Claim:
1. A method of treating a thrombus, comprising: inserting a catheter having a proximal end and a distal end into a patient and advancing the distal end of the catheter to a treatment site; advancing a thrombus treatment device to the treatment site through a lumen of the catheter, the thrombus treatment device comprising: (a) a body frame portion, wherein the body frame portion defines one or more interstices, (b) a tether portion that includes one or more tethers, said one or more tethers extending from the body frame portion to a collar that is coupled to a support wire, and (c) a filter portion that extends from the body frame portion; positioning the thrombus treatment device within the lumen of the catheter at a position wherein the body frame portion is generally aligned with at least a portion of a thrombus at the treatment site, and proximally withdrawing the catheter; providing a distally directed force to the support wire to advance the collar to a location substantially within a region interior of the body frame portion or substantially within a region interior of the filter portion; and rotationally actuating the support wire, wherein the rotational actuation of the support wire causes a swiveling motion of the one or more tethers, the one or more tethers being adapted to macerate the thrombus.
