Abstract:
1. An infusion catheter comprising: an elongate catheter body defining a longitudinal axis extending between a proximal body component and a distal body component, the proximal body component including a proximal body outer surface and a proximal body inner surface, and the distal body component including a distal body outer surface, a distal body inner surface, and a tapered distal tip; the proximal body inner surface defining a fluid supply lumen extending between a supply lumen inlet and a supply lumen outlet, and the distal body inner surface defining an infusion lumen connecting with the fluid supply lumen and extending between an infusion lumen inlet and a plurality of infusion lumen outlets formed in the distal body outer surface; the distal body component further having a skeleton, and a porous infusion control textile contacting the skeleton and including the plurality of infusion lumen outlets, the porous infusion control textile extending circumferentially about the longitudinal axis and defining a fluid emission profile of the infusion catheter; the porous infusion control textile further including a fiber network extending between a proximal textile end and a distal textile end, the fiber network including interlaced fibers and having a space filling configuration which is substantially circumferentially uniform and axially non-uniform; and the space filling configuration is of a higher density of the interlaced fibers in a pattern of interlacing at the proximal textile end, a lower density of the interlaced fibers in the same pattern of interlacing at the distal textile end, and a medium density of the interlaced fibers in the same pattern of interlacing between the proximal and distal textile ends, and the fiber network defines a pressure sensitive flow rate property and a pressure insensitive flow distribution property, of the fluid emission profile.
