Abstract
The present disclosure provides catheters comprising polytetrafluoroethylene (PTFE) tubes with advantageous combinations of strength, flexibility, and size. Such tubes can exhibit features including an average wall thickness of 0.001″ or less, a tensile stress at break of greater than 5000 psi, and a storage modulus of less than 100,000 psi at 37° C. These tubes can be also be provided independently (i.e., not within a catheter) and can be employed in various applications.
