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). The tube (11) further includes a polymeric bonding layer (18) positioned over and contacting at least the coil (14). The polymeric layer (18) is preferably heat-shrinkable shrinkable tubing made of one or more of nylon or polyurethane. The tube (11) optionally includes an inner liner (20) beneath and in contact with at least part of the coil (14), the liner (20) preferably being composed of PTFE. The polymeric layer (18) maintains the coil (14) in its stressed, radially expanded condition, for example, by adhesion to the coil (14) (such as by thermal bonding to it).
