First Claim
Patent Images
1. An anti-extravasation system comprising:
- a catheter having a length and outer diameter suitable for extending from a peripheral vein insertion point on a patient to a treatment site, said catheter characterized by an elongated venous section located distal to an interstitial section and comprising;
an inflow lumen;
at least one drainage lumen;
a dissolvable plug disposed within the at least one drainage lumen; and
a plurality of apertures disposed only in the interstitial section of the catheter, said plurality of apertures in fluid communication with the at least one drainage lumen and adapted to drain fluid from tissue surrounding the insertion point when the catheter is operably disposed within the patient;
wherein the venous section of the catheter comprises a uniform outer surface and is structured to prevent fluid communication between the outer surface of the venous section and the at least one drainage lumen; and
a hub proximal to the interstitial section and placed in fluid communication with the inflow lumen and the at least one drainage lumen.

Abstract
The disclosed devices and methods provide for the minimization of fluid extravasation during use of infusion catheters such as peripherally inserted central catheters and central venous catheters. The anti-extravasation catheter allows a surgeon to drain fluids from soft tissue surrounding an infusion site while also providing fluid inflow to a patient.

12. A method for performing chemotherapy comprising:
-
providing a chemotherapy therapeutic fluid source; providing an anti-extravasation catheter, said catheter having a length and outer diameter suitable for extending from a peripheral vein insertion point on a patient to a treatment site, said catheter characterized by an elongated venous section located distal to an interstitial section and comprising; an inflow lumen; at least one drainage lumen; and a plurality of apertures disposed only in the interstitial section of the catheter, said plurality of apertures in fluid communication with the at least one drainage lumen and adapted to drain fluid from tissue surrounding the insertion point when the catheter is operably disposed within the patient; a dissolvable plug disposed within the at least one drainage lumen and in fluid communication with the plurality of apertures; wherein the venous section of the catheter comprises a uniform outer surface and is structured to prevent fluid communication between the outer surface of the venous section and the at least one drainage lumen; disposing the anti-extravasation catheter inside a patient; placing the plurality of apertures in fluid communication with tissue surrounding the insertion point; infusing the chemotherapy therapeutic fluid into the patient through the catheter; and draining interstitial fluid from tissue surrounding the catheter insertion point during a chemotherapeutic session through the plurality of apertures. - View Dependent Claims (13, 14, 15, 16, 17)
