The multi-catheter infusion system includes a cannula and a plurality of catheters. The cannula includes a first end for connecting to a drug delivery system and a second end for connecting to the plurality of catheters. The plurality of catheters are in fluid communication with the cannula for delivering a drug to a target area of a patient. Each catheter includes a multi-orifice distal end. ## Claims ### Claim 1 A multi-catheter infusion system comprising: a cannula including a first end for connecting to a drug delivery system and a second end opposite the first end; and a plurality of catheters attached to the second end in fluid communication with the cannula for delivering a drug to a target area of a patient, wherein each catheter includes: a multi-orifice distal end, and a detachable hook shaped needle distal to the multi-orifice distal end. ### Claim 2 (depends on 1) The multi-catheter infusion system of claim 1, wherein the multi-orifice distal end includes a first orifice and a second orifice circumferentially spaced from the first orifice. ### Claim 3 (depends on 1) The multi-catheter infusion system of claim 1, wherein the multi-orifice distal end includes a plurality of orifices spirally arranged. ### Claim 4 (depends on 1) The multi-catheter infusion system of claim 1, wherein the multi-orifice distal end includes a first orifice and a second orifice that overlaps a circumferential span of the first orifice. ### Claim 5 (depends on 1) The multi-catheter infusion system of claim 1, wherein each catheter further includes a frangible connection connecting the detachable guide needle to a distal end of the catheter. ### Claim 6 (depends on 5) The multi-catheter infusion system of claim 5, wherein the frangible connection is composed of a plastic. ### Claim 7 (depends on 5) The multi-catheter infusion system of claim 5, wherein the frangible connection has a lower tensile strength or a scored section, or is a notch, a slit, or a perforation. ### Claim 8 (depends on 5) The multi-catheter infusion system of claim 5, wherein the frangible connection extends from a distally facing end of the catheter. ### Claim 9 (depends on 1) The multi-catheter infusion system of claim 1, wherein at least one of the plurality of catheters has a cross-sectional diameter sufficient to draw fluid from the cannula by capillary action. ### Claim 10 (depends on 1) The multi-catheter infusion system of claim 1, wherein each of the plurality of catheters are 28-15 gauge catheters. ### Claim 11 (depends on 1) The multi-catheter infusion system of claim 1, wherein each of the plurality of catheters has a diameter narrower than a diameter of the cannula. ### Claim 12 (depends on 1) The multi-catheter infusion system of claim 1, wherein the plurality of catheters collectively have an overall diameter that is less than an overall diameter of the cannula. ### Claim 13 (depends on 1) The multi-catheter infusion system of claim 1, wherein the second end of the cannula includes a regulator. ### Claim 14 (depends on 13) The multi-catheter infusion system of claim 13, wherein the regulator is a flow regulator including a valve for regulating fluid flow through the cannula. ### Claim 15 (depends on 13) The multi-catheter infusion system of claim 13, wherein the regulator is a pressure regulator including a globe valve for regulating fluid pressure through the cannula. ### Claim 16 (depends on 13) The multi-catheter infusion system of claim 13, wherein the regulator has an overall diameter the same as a diameter of the cannula. ### Claim 17 (depends on 13) The multi-catheter infusion system of claim 13, wherein the plurality of catheters are attached to the second end of the cannula downstream the regulator. ### Claim 18 A multi-catheter infusion system comprising: a cannula including a first end for connecting to a drug delivery system and a second end opposite the first end, wherein the second end includes a regulator having an overall diameter larger than a diameter of the cannula with a tapered portion to facilitate removal of the multi-catheter infusion system through a patient's skin; and a plurality of catheters attached to the second end in fluid communication with the cannula for delivering a drug to a target area of a patient, wherein each catheter includes: a multi-orifice distal end, and a detachable needle. ### Claim 19 A multi-catheter infusion system comprising: a cannula including a first end for connecting to a drug delivery system and a second end opposite the first end; and a plurality of catheters attached to the second end in fluid communication with the cannula for delivering a drug to a target area of a patient, wherein each catheter includes: a multi-orifice distal end, and a detachable needle having a frangible connection to the catheter.
