The midline catheter includes a shaft defining a lumen, the shaft having a distal end and a proximal end. The distal end includes two or more opposing notches thereon, each of the notches having an open notch distal end and an opposing notch proximal end formed as an arch. The catheter may also include written indicia thereon to indicate that it is a midline catheter and/or is power injectable or non-power-injectable. ## Claims ### Claim 1 A midline catheter comprising: a shaft defining a lumen, said shaft having a distal end and a proximal end wherein said distal end includes two or more opposing notches thereon, each of said notches having an open notch distal end and an opposing notch proximal end formed as an arch; wherein an interior of the shaft is undivided between the proximal end of the shaft and the proximal end of each of the two or more opposing notches; wherein said distal end includes a radiused edge circumferentially disposed thereon; wherein said catheter further includes a luer and a hub coupled to the proximal end and wherein an indicia is printed on the luer, the hub, the shaft, or combinations of the foregoing. ### Claim 2 (depends on 1) The midline catheter of claim 1 wherein each of said arches are formed in the shaft of the midline catheter. ### Claim 3 (depends on 1) The midline catheter of claim 1 wherein the radiused edge is configured to reduce mechanical irritation during an insertion and a dwell period. ### Claim 4 (depends on 1) The midline catheter of claim 1 wherein said catheter is sized as 3F single, 4F single, or 4F double. ### Claim 5 (depends on 1) The midline catheter of claim 1 wherein said printed indicia indicates that the catheter is power-injectable. ### Claim 6 (depends on 1) The midline catheter of claim 1 wherein said printed indicia indicates that the catheter is not power-injectable. ### Claim 7 (depends on 1) The midline catheter of claim 1 wherein said printed indicia indicates that the catheter is a mid-line catheter. ### Claim 8 (depends on 1) The midline catheter of claim 1 wherein a length of the catheter is 10 cm. ### Claim 9 (depends on 1) The midline catheter of claim 1 wherein a dimension of each of said notches is from 0.020 inches to 0.025 inches wide and 0.038 inches by 0.042 inches in length. ### Claim 10 (depends on 9) The midline catheter of claim 9 wherein the dimension of each of said notches is 0.022 inches wide and 0.040 inches in length. ### Claim 11 (depends on 1) The midline catheter of claim 1 wherein a dimension of the radius of the radiused edge is from 0.007 inches to 0.010 inches. ### Claim 12 (depends on 11) The midline catheter of claim 11 wherein the dimension of the radius is 0.008 inches. ### Claim 13 (depends on 1) The midline catheter of claim 1 wherein the interior of the shaft between the proximal end of each of said notches is substantially circular. ### Claim 14 A midline catheter comprising: a shaft defining a lumen, said shaft having a distal end and a proximal end wherein said distal end includes two or more opposing notches thereon, each of said notches having an open notch distal end and an opposing notch proximal end formed as an arch; wherein an interior of the shaft is undivided between the proximal end of the shaft and the proximal end of each of the two or more opposing notches; wherein said distal end includes a radiused edge circumferentially disposed thereon; wherein said catheter further includes a luer and a hub and wherein at least one of the luer, the hub, or the shaft is color coded to indicate that the catheter is power-injectable or non-power-injectable. ### Claim 15 A midline catheter comprising: a shaft defining a lumen, the shaft having a distal end and a proximal end; the distal end includes at least two opposing notches, with each notch of the at least two opposing notches having an open notch distal end and an opposing notch proximal end formed as an arch; wherein an interior of the shaft between the proximal end of each of the at least two opposing notches is substantially circular; wherein the distal end includes a radiused edge circumferentially disposed thereon; wherein said catheter further includes a luer and a hub coupled to the proximal end and wherein an indicia is printed on the luer, the hub, the shaft, or combinations of the foregoing. ### Claim 16 (depends on 15) The midline catheter of claim 15 wherein each of the arches are formed in the shaft of the midline catheter. ### Claim 17 (depends on 15) The midline catheter of claim 15 wherein the radiused edge is configured to reduce mechanical irritation during an insertion and a dwell period. ### Claim 18 (depends on 15) The midline catheter of claim 15 wherein the catheter is sized as 3F single, 4F single, or 4F double. ### Claim 19 (depends on 15) The midline catheter of claim 15 wherein the interior of the shaft is undivided between the proximal end and the proximal end of each of said notches.
