Abstract

A medical device (10) including a tube (11) having a highly uniform and repeatable inner and outer diameter, the tube (11) possessing good trackability, pushability and torquability, and the tube (11) being highly resistant to collapse, necking or kinking during use. The tube (11) first includes a metal coil (14) in a stressed, radially expanded condition, the metal coil (14) preferably being formed as a flat wire. The tube (11) also includes a metal braid (16) extending over at least part of the coil (14) and further includes a polymeric bonding layer (18) positioned over and contacting at least the coil (14). The tube (11) optionally includes an inner liner (20) beneath and in contact with at least part of the coil (14). The polymeric layer (18) maintains the coil (14) in its stressed, radially expanded condition.
