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.
Claims22
A catheter for treating a symptomatic or asymptomatic patient with a deliverable medicant, comprising:
- a shaft formed by an outer wall and a spaced inner wall, wherein the inner wall defines an interior lumen that extends to a distal end of the shaft that is configured to be positionable within a vein lumen of the patient, the interior lumen being in fluid communication with a first port and a second port, wherein the shaft further defines a blind ended outer lumen in fluid communication with a third port that is in fluid communication with the deliverable medicant, and wherein the interior lumen and the blind ended outer lumen are configured to prevent fluid communication therebetween, and
- a plurality of fenestrations defined in an outer wall surface of the outer wall of a proximal portion of the shaft, wherein the plurality of fenestrations is in fluid communication with the blind ended outer lumen and the deliverable medicant, wherein the plurality of fenestrations is in communication with a subcutaneous tract of tissue surrounding the proximal portion of the shaft to maintain a portion of the outer catheter surface and the subcutaneous tract proximate the proximal portion shaft of the catheter bacteria free.
A catheter system to treat a symptomatic or asymptomatic patient, comprising:
- a deliverable medicant;
- a shaft formed by an outer wall and a spaced inner wall, wherein the inner wall defines an interior lumen that extends to a distal end of the shaft that is configured to be positionable within a vein lumen of the patient, the interior lumen being in fluid communication with at least one port, wherein the shaft further defines a blind ended outer lumen in fluid communication with a medicant port that is in fluid communication with the deliverable medicant, and wherein the interior lumen and the blind ended outer lumen are configured to prevent fluid communication therebetween, and
- a plurality of fenestrations defined in an outer wall surface of the outer wall of a proximal portion of the shaft, wherein the plurality of fenestrations is in fluid communication with the blind ended outer lumen and the deliverable medicant, wherein the plurality of fenestrations is in communication with a subcutaneous tract of tissue surrounding the proximal portion of the shaft to maintain at least a portion of the outer catheter surface and the subcutaneous tract proximate the proximal portion shaft of the catheter bacteria free.
