76. A method of treating a bodily lumen comprising:
releasing an acidic agent at or adjacent to a hydrolytically degradable polymer stent implanted within a bodily lumen, the acidic agent lowers the pH of bodily fluid at or adjacent to the stent, the lowered pH of the bodily fluid increases the degradation rate of the stent. - View Dependent Claims (77, 78, 79, 80, 81, 82)

83. A method of treating a bodily lumen comprising:
-
positioning a delivery device within a bodily lumen at or adjacent to a hydrolytically degradable polymer stent implanted within the bodily lumen; disposing an acidic agent into the delivery device; releasing the acidic agent from the delivery device into the bodily lumen, wherein the released acidic agent lowers the pH of the bodily fluid at or adjacent to the stent below physiological pH which increases the degradation rate of the stent. - View Dependent Claims (84, 85, 86, 87, 88, 89, 90, 91)
