Abstract
A drug eluting catheter includes an active agent, such as a drug or chemical substance, which is integrated with the catheter and allows variable dosing of the agent for elution to the patient's body. The catheter includes a dosing region and graduated markings or is associated with a measurement device that includes graduated markings that correspond to a range of dose of the active agent associated with the catheter. By removing or masking an undesired dosing region prior to administration, a user may vary the dosage to suit a patient's needs.
