摘要:
Apparatus and methods are provided for making coated liners and/or tubular devices including such coated liners. A sleeve may be provided that includes an outer first surface and an inner second surface extending between first and second ends thereof, and a hydrophilic or other coating may be applied to the first. The coated sleeve may be cut between the first and second ends to create opposing edges extending between the first and second ends, and the cut sleeve may be reversed such that the coated first surface defines an inner surface and the opposing edges are disposed adjacent one another, thereby providing a coated liner. Optionally, a tubular structure, e.g., one or more reinforcing layers and/or or outer layers may be attached around the coated liner, thereby providing a tubular device including an inner surface with a desired coating.

Apparatus and methods are provided for delivering fluids into a patient's body that includes a tubular member including a proximal end, a distal end sized for introduction into a patient's body, and a fluid delivery lumen extending between the proximal and distal ends; and a flexible pad on the distal end including a tissue contacting surface, a passage communicating with the fluid delivery lumen, and plurality of capillary channels in the tissue contact surface communicating with the passage, the capillary channels configured to deliver fluid from the fluid delivery lumen and passage to tissue contacted by the tissue contact surface.

A hub is provided for a sheath, catheter, or other tubular device that includes a tubular body comprising a proximal end, a distal end, and a hub passage extending between the proximal end and the distal end; a valve mounted in the tubular body adjacent the proximal end comprising a proximal surface adjacent the proximal end and a distal surface adjacent an intermediate region of the hub passage; a side port comprising a first end coupled to an outer surface of the tubular body adjacent the intermediate region, a second outer end, and a port passage extending between the second end and the first end and communicating with the intermediate region of the hub passage; and a guide element in the side port adjacent the first end for directing fluid introduced into the second end through the port passage towards the distal surface of the valve.
