Abstract
In examples, a microcatheter includes an enhanced inner liner that has a low coefficient of friction and improved toughness, which facilitates delivery of expandable vascular reconstruction devices. The microcatheter may include a stretched polytetrafluoroethylene (PTFE) liner, which may be stretched longitudinally and not circumferentially or radially over at least a portion of a length of the microcatheter. The stretched PTFE inner liner may result in the reduction of a delivery friction and improved toughness and resistance to scraping.
