A method of forming a parison for forming a balloon for a balloon catheter, comprising:
- forming a tube as the parison by coextruding a radiopaque-enhanced material and a non-radiopaque-enhanced material in an intermittent fashion.
A method of forming a parison for forming a balloon for a balloon catheter, comprising:
- forming a tube as the parison by coextruding a radiopaque-enhanced material and a non-radiopaque-enhanced material together at different time intervals.
A method of forming a parison for forming a balloon for a balloon catheter, comprising:
- forming a tube as the parison by coextruding a first material having a radiopacifier with a second material;
- and
- adjusting an amount of radiopacity provided by the first material during the coextruding, wherein the adjusting step is performed by controlling an amount of radiopacifier in the first material.
