ABSTRACT:
The present invention comprises an embolectomy catheter for the removal of an embolus within a vessel of a patient, including a catheter shaft having a distal end with a diametrically adjustable hinged compartment thereat. The catheter shaft has a proximal end with a handle attached thereon. A longitudinally displaceable cannula is connected to the distal end of the catheter shaft and to a slidable tab in the handle, to permit controlled adjustment of the diametric size of the hinged compartment arranged adjacent the distal end of the catheter when the slidable tab is moved relative to the handle, to allow a physician to open the compartment to any desired size relative to a patient's vessel. The compartment may then be pulled through the vessel via a pull on the handle, to collect any embolus therewithin.
