Definitions
- a distal shaft 42 includes an outer tube 46 and an orifice 48 through the outer wall of outer tube 46 and a lumen 47 within.
- a balloon 50 is disposed distally on distal shaft 42, having an envelope 52, a proximal waist 54, and a distal waist 56.
- An inner tube 58 is inserted into outer tube 46 and lumen 47 through orifice 48.
- Inner tube 58 serves as a distal guide wire tube in catheter 20. The relatively short length of inner tube 58 allows the single operator or rapid exchange of catheter 20 over a guide wire.
- inner tube 58 can lie atop outer tube 46 proximal of entry orifice 48.
- the entry of inner tube 58 into outer tube 46 preferably includes bonding or affixing of the tubes to secure inner tube 58 in place.
- This bonding preferably includes bonding in the region proximate orifice 48 and can include bonding both proximal and distal of orifice 48.
- inner tube wall 818 is formed of a lubricious material to provide a lubricious inside surface 822 offering less resistance when advancing the catheter over a guide wire.
- outer tube wall 831 is formed of the same or compatible lubricious material as inner tube 805. This allows bonding between inner and outer tubes as indicated, for example, at region 850. In some embodiments, bonding occurs distal of orifice 804 and near orifice 804. In other embodiments, the bonding occurs further distal of orifice 804. In other embodiments, bonding occurs proximal of orifice 804 as indicated, for example, by region 851. Any suitable location for bonding inner to outer tubes is within the scope of the invention. Referring now to Figure 3, a transverse cross section taken through 3-3 in
