Infusion Catheter And Method

摘要

An infusion catheter includes an elongate catheter body having a proximal body component and a distal body component. The distal body component includes a distal body outer surface and a distal body inner surface defining an infusion lumen. The distal body component further includes a skeleton, and a porous infusion control textile contacting the skeleton and extending circumferentially about a longitudinal axis of the catheter and defining a fluid emission profile thereof. The porous infusion control textile further includes a fiber network having a higher density space filling configuration at a proximal textile end and a lower density space filling configuration at a distal textile end, and defining a pressure sensitive flow rate property and a pressure insensitive flow distribution property of the fluid emission profile.
