Abstract
The present disclosure provides a catheter system including a plurality of fenestrations along the shaft of the catheter, wherein the fenestrations allow for continuous or intermittent infusion of antiseptics and/or antibiotics to avoid and treat bacterial colonization or infection of the subcutaneous tract and to minimize subcutaneous tunnel colonization and fibrin sheath in symptomatic or asymptomatic patients. The present catheter system can also include a removable abrasive component on the catheters tip to assist with mechanical debridement of subcutaneous tract and intravascular fibrin sheath.
