ABSTRACT:
A weak, positive electric charge is induced at the distal or discharge end of an infusion catheter to inhibit tissue ingrowth relative to the discharge opening. The charge may be induced by connecting an electrode carried at the distal end to a suitable source of electric potential. Alternatively, a positively charged member or coating may be provided at the distal end of the catheter.
