Abstract
A venous catheter having a catheter tip comprising recessed diffusion holes for increasing the snag-resistance of the venous catheter. The invention further provides systems and methods for providing axial ridges interposed between diffusion holes for increasing the rigidity of the vented catheter tip.
Claims20
A peripheral catheter, comprising:
- a catheter body comprising an outer surface, a proximal end, a distal end, and a lumen, wherein the distal end comprises a distal opening, wherein the lumen extends between the proximal end and the distal lumen opening;
- a recess formed in the outer surface of the catheter body, wherein the recess comprises two opposing sidewalls and a planar surface separating the two opposing sidewalls;
- and
- a hole positioned in the planar surface such that the planar surface surrounds the hole, wherein the hole is formed through a wall thickness of the catheter body and in fluid communication with the lumen.

A method for manufacturing a snag-resistant, vented peripheral catheter, the method comprising:
- providing a catheter body comprising an outer surface, a proximal end, a distal end, and a lumen, wherein the distal end comprises a distal opening, wherein the lumen extends between the proximal end and the distal lumen opening;
- providing a recess formed in the outer surface of the catheter body, wherein the recess comprises two opposing sidewalls and a planar surface separating the two opposing sidewalls;
- and
- providing a hole positioned in the planar surface such that the planar surface surrounds the hole, wherein the hole is formed through a wall thickness of the catheter body and in fluid communication with the lumen.

A peripheral catheter, comprising:
- a catheter body comprising an outer surface, a proximal end, a distal end, and a single lumen, wherein the distal end comprises a distal opening, wherein the single lumen extends between the proximal end and the distal lumen opening;
- a recess formed in the outer surface of the catheter body, wherein the recess comprises a first side wall, a second side wall, and a planar surface extending from the first side wall to the second sidewall;
- and
- a hole positioned in the planar surface such that the planar surface surrounds the hole, wherein the hole comprises a third sidewall, wherein the third sidewall comprises an outer edge, wherein the hole is formed through a wall thickness of the catheter body and in fluid communication with the lumen.
