Abstract
A method of making a catheter, 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.
Claims15
A method of manufacturing a catheter, the method comprising:
- forming an elongated tube structure comprising a proximal end, a distal end and at least one preset curved portion located between the proximal end and the distal end, the elongated tube structure comprising a first material and a second material, wherein the method further comprises:
- locating the first material along the preset curved portion, wherein the first material extends proximally and distally along the preset curved portion;
- and
- locating the second material along the preset curved portion, wherein the second material extends proximally and distally along the preset curved portion, and further wherein the second material extends beyond the first material both proximally and distally.
A method of manufacturing a catheter, the method comprising:
- forming an elongated tube structure comprising a proximal end, a distal end and at least one preset curved portion located between the proximal end and the distal end, the elongated tube structure comprising a first material having a first stiffness and a second material having a second stiffness less than the first stiffness, wherein the method further comprises:
- locating the first material along the preset curved portion such that it extends both proximally and distally along the preset curved portion;
- and
- locating the second material 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 method of manufacturing a catheter, the method comprising:
- forming an elongated tube structure comprising a proximal end, a distal end and at least one preset curved portion located between the proximal end and the distal end, the elongated tube structure comprising a first material, a second material, and a third material, wherein the method further comprises:
- locating the first material along the preset curved portion, wherein the first material extends proximally and distally along the preset curved portion;
- locating the second material along the preset curved portion, wherein the second material extends proximally and distally along the preset curved portion, and further wherein the second material extends beyond the first material both proximally and distally;
- and
- locating the third material between the first material and the second material.
