Abstract

See full text

A catheter can have a textured outer body surface with protrusions and/or indentations that can reduce friction between the outer body surface and vascular anatomy or an inner lumen of another catheter in contact with the outer body surface. The catheter can include protrusions and/or indentations on an inner lumen surface that can reduce friction between the inner lumen surface and an outer body surface of another catheter within the example catheter. The protrusions can be filled with a lubricant or vasodilating drug, and the protrusions can be configured to break to release the fluid in response to forces on the protrusion during navigation through vascular anatomy and/or an inner lumen of another catheter. The catheter can include a metallic tubular reinforcing layer with openings through which the protrusions and/or indentations extend and/or protrusions and/or indentations shaped into the reinforcing layer.
