Abstract
A thrombus engagement tool having a flexible shaft, a clot engagement tip, and a handle. The engagement tip may include one or more radially outwardly extending structures such as a helical thread. The helical thread can be advanced through a catheter to engage a clot. The handle may be configured to be rotated by hand. When the handle is rotated, the helical thread of the engagement tip can rotate in the same direction thereby allowing the helical threat to engage the clot. The helical thread can wrap around the flexible shaft at least about one, two, or four or more full revolutions, but in some cases no more than about ten or no more than about six revolutions.
