Thrombectomy devices with control assemblies

A thrombectomy device comprising:

• a handle;
• a first tube coupled with the handle, the first tube including a proximal end portion and a distal end portion;
• a window positioned on a side wall of the first tube and in the distal end portion of the first tube;
• an extraction core tube extending within the first tube, the extraction core tube includes a proximal core portion and a distal core portion, the distal core portion is proximate to the distal end portion of the first tube;
• a rotatable extractor positioned about the extraction core tube, the rotatable extractor includes a distal extractor portion and a proximal extractor portion;
• wherein the distal extractor portion includes a first pitch and the proximal extractor portion includes a second pitch, the first pitch less than the second pitch;
• and
• wherein the window exposes at least a portion of the first pitch of the distal extractor;
• and
• a cage surrounding at least a portion of the distal end portion of the first tube.

A thrombectomy device, comprising;

• a handle;
• a control assembly housed within the handle, the control assembly including:
• a first arm extending from the handle;
• and
• a second arm extending within the first arm;
• a cage having a proximal cage portion coupled with the first arm and a distal cage portion coupled with the second arm;
• and
• a rotatable extractor extending within the first arm and positioned around the second arm, the extractor including a helical form positioned around the second arm, the helical form including a first pitch and a second pitch;
• wherein the second arm is rotatably stationary while the helical form is rotatable about the second arm;
• wherein the first pitch is narrower than the second pitch;
• and
• wherein at least one of the first pitch or the second pitch is positioned within the cage.
