Abstract: A catheter extraction tool has a head that can be placed in position to significantly surround a diameter of a catheter. The head is shaped to have a low enough profile above the catheter to allow the head to be slid down the catheter and into a subdermal region in which the catheter is subdermal with respect to a patient. The head of the catheter extraction tool is expanded sufficiently to slide the head over a catheter cuff located in the subdermal region. After the head of the catheter extraction tool slides over the catheter cuff, the head is contracted to engage the catheter so that a user can pull the catheter out of the patient using the catheter extraction tool.
