BIDIRECTIONAL CEREBRAL SPINAL FLUID INFUSION CATHETER WITH COOLING MECHANISM AND METHOD OF USE
First Claim
1. A device for delivering a treatment solution, the device comprising:
- a bi-directional catheter comprising a first lumen and a second lumen,wherein the first lumen comprises a proximal end having an inflow portal and a distal end having an outflow portal, andthe second lumen comprises a side wall having at least one inflow portal allowing for fluid communication from outside the side wall to inside the side wall and the second lumen further comprising a proximal end having an outflow portal; and
a pump comprising an input channel, a reservoir for receiving and containing the treatment solution, a cooling apparatus for cooling the treatment solution, and an output channel;
wherein the outflow portal of the second lumen of the bi-directional catheter is in fluid communication with the input channel of the pump and the output channel of the pump is in fluid communication with the inflow portal of the first lumen.

Abstract
A device and method for delivering a treatment solution includes a bi-directional catheter comprising at least a first lumen and a second lumen, wherein the first lumen comprises a proximal end having an inflow portal and a distal end having an outflow portal, and the second lumen comprises a side wall having at least one inflow portal allowing for fluid communication from an outer surface of the side wall to an inner surface of the side wall and the second lumen further comprises a proximal end having an outflow portal. The device and method further include a pump having an input channel, a reservoir for receiving and containing the treatment solution, a cooling apparatus for cooling the treatment solution, and an output channel. The outflow portal of the second lumen of the catheter is in fluid communication with the input channel of the pump and the output channel of the pump is in fluid communication with the inflow portal of the first lumen.

7. A method of treating or preventing damage to a patient'"'"'s central nervous system, comprising:
-
providing a catheter comprising a first lumen and a second lumen, wherein the first lumen comprises a proximal end having an inflow portal and a distal end having an outflow portal, and the second lumen comprises a sidewall having at least one inflow portal providing fluid communication from outside the side wall to inside the side wall and the second lumen further comprises a proximal end having an outflow portal; providing a pump comprising an input channel, a reservoir for receiving and containing the treatment solution, a cooling apparatus for producing a cooled treatment solution, and an output channel; wherein the outflow portal of the second lumen of the catheter is in fluid communication with the input channel of the pump and the output channel of the pump is in fluid communication with the inflow portal of the first lumen; inserting the catheter into the patient'"'"'s intrathecal space; withdrawing a portion of the patient'"'"'s cerebrospinal fluid through the second lumen catheter by use of the pump; delivering the patient'"'"'s cerebrospinal fluid to the reservoir of the pump and cooling the patient'"'"'s cerebrospinal fluid with the cooling apparatus to produce a cooled treatment fluid; introducing the cooled treatment fluid to the patient'"'"'s intrathecal space through the first lumen of the catheter. - View Dependent Claims (8, 9, 10, 11, 12)
