Strip lined catheters and methods for constructing and processing strip lined catheters

A method for making a catheter body sized for introduction into a patient's body, comprising:

• directing a strip of material substantially continuously from a reel to a guide to place the strip adjacent an elongate mandrel such that a length of the strip extends axially along the mandrel and a surface modification on a first surface of the strip is oriented towards the mandrel;
• substantially continuously rolling the strip at least partially around the mandrel such that the surface modification is disposed radially inwardly towards the mandrel;
• and
• substantially continuously wrapping one or more strip-constrainment members around the rolled strip to create one or more strip-mandrel-constrainment member subassemblies;
• and
• encasing the one or more strip-mandrel-constrainment member subassemblies in a jacket to create one or more tubular bodies,
• wherein side edges of the strip remain unattached to one another when the strip is rolled around the mandrel and the one or more strip-constrainment members are wrapped around the rolled strip.

A method for making a catheter body sized for introduction into a patient's body, comprising:

• directing a strip of material substantially continuously from a reel to a guide to place the strip adjacent an elongate mandrel such that a length of the strip extends axially along the mandrel and a coating on a first surface of the strip is oriented towards the mandrel;
• substantially continuously rolling the strip at least partially around the mandrel such that the coating is disposed radially inwardly towards the mandrel and side edges of the strip remain unattached to one another;
• and
• substantially continuously wrapping one or more strip-constrainment members around the rolled strip to create one or more strip-mandrel-constrainment member subassemblies;
