Abstract
A catheter and method of making the same, including an elongated tube structure having a proximal end and at least one preset curved portion proximate a distal end. The preset curved portion includes a first material located generally along an outer surface of the preset curved portion and a second material located generally along an inside surface of the preset curved portion. The first material preferably has a greater stiffness than the second material, so that the catheter is capable of assuming a generally straight configuration without plastic deformation.
Claims18
A catheter comprising an elongated tube structure having a proximal end and at least one preset curved portion proximate to a distal end of the elongated tube structure, the elongated tube structure comprised of a first material and a second material, the first material located along the preset curved portion such that it extends proximally and distally along the preset curved portion, the second material located along the preset curved portion and extending both proximally and distally from the preset curved portion such that it extends beyond the first material both proximally and distally.
A catheter comprising an elongated tube structure having a proximal end and at least one preset curved portion proximate to a distal end of the elongated tube structure, the preset curved portion comprising:
- a first material having a first stiffness located along the preset curved portion such that it extends both proximally and distally along the preset curved portion;
- and
- a second material having a second stiffness less than the first stiffness located along the preset curved portion so that the catheter is capable of assuming a generally straight configuration without plastic deformation, the second material extending both proximally and distally from the preset curved portion such that it extends beyond the first material both proximally and distally.
A catheter comprising an elongated tube structure having a proximal end and at least one preset curved portion proximate to a distal end of the elongated tube structure, the elongated tube structure comprised of a first material, a second material, and a third material, the first material located generally along an outer radius of the preset curved portion, the second material located generally along an inner surface of the preset curved portion, and the third material interposed between the first and second materials.
