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.
Claims7
A peripheral catheter, comprising:
- a catheter body comprising an outer surface, a proximal end, a distal end, and an inner surface forming a lumen, wherein the distal end comprises a catheter tip opening, wherein the lumen extends between the proximal end and the catheter tip 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 plurality of holes positioned in the planar surface such that the planar surface surrounds each of the plurality of holes, wherein the plurality of holes are formed through the catheter body and in fluid communication with the lumen,
- an inner surface forming a hole of the plurality of holes, wherein
- the inner surface extends from the planar surface to the lumen, wherein a distal portion of the inner surface is disposed opposite a proximal portion of the inner surface, wherein the distal portion of the inner surface and the proximal portion of the inner surface are oriented at a same angle oblique to the inner surface of the catheter body, wherein the distal portion of the inner surface is parallel to the proximal portion of the inner surface and spaced apart from the proximal portion of the inner surface by the hole.
