Catheter, fluid conveying method, and percutaneous procedure |
摘要 |
A catheter includes an elongate catheter body having an outer surface with a non-uniform contour and including a plurality of maximum surface elevation points and a plurality of minimum surface elevation points defining a non-uniform elevation profile relative to a longitudinal axis of the catheter body. The outer surface further includes a fluid transfer interface which includes the plurality of minimum surface elevation points and a plurality of porous surface areas, and a tissue contact interface which includes the plurality of maximum surface elevation points and a plurality of nonporous surface areas. The tissue contact interface inhibits external occlusion of the fluid transfer interface during transferring fluid between a fluid lumen defined by the elongate catheter body, and an intraluminal space such as an intravascular space within a patient.
