What can cause the catheter to dislodge or tear?
Catheters become dislodged primarily because of certain motions or sudden or repetitive movements, so exercise and other activities should be approached with caution. Excessive or repetitive bending, twisting, bouncing, or stretching can move or stretch the catheter – dislocating or even tearing it. You should know where your catheter is implanted and avoid movements which may stretch or strain either the catheter or the stitches holding your pump in place. A catheter can also tear because of a nick caused by the stitches during your surgery, or by rubbing on your bones. Although the catheter is made of flexible and durable materials, it is still subject to wear. Seemingly harmless movements can cause unseen damage over time. Any damage may require surgery to repair the catheter.
