Abstract
A thrombus removal device includes a shaft with a distal end and a proximal end, a sheath with a distal end and a proximal end, and a helical coil attached at a proximal end to the distal end of the shaft and is disposed within the lumen of the sheath in a closed configuration. The helical coil includes a plurality of body portions with turns spaced apart longitudinally and laterally to facilitate screwing the helical coil into a thrombus and also providing an open area into which the thrombus can be captured. A distal tip of the helical coil is provided with a loop, an angle of which is about the same as the angle of at least one body portion. The helical coil assumes an open configuration when the sheath is retracted proximally from the distal tip.
