Abstract
A method of making a radially expandable fluid delivery device includes providing a tube of biocompatible fluoropolymer material with a predetermined porosity based on an extrusion and expansion forming process, applying a radial expansion force to the tube expanding the tube to a predetermined diameter dimension, and removing the radial expansion force. The tube is radially inelastic while sufficiently pliable to be collapsible and inflatable from a collapsed configuration to an expanded configuration upon introduction of an inflation force, such that the expanded configuration occurs upon inflation to the predetermined diameter dimension. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device.
