Welding method using fiber laser for components of a medical device

A method of forming a medical device, comprising:

• preparing a joint region by introducing at least a portion of a second tubular member into a lumen of a first tubular member, wherein the first tubular member comprising a first polymer, wherein the second tubular member comprising a second polymer;
• positioning a compression sleeve over at least a portion of the first tubular member at the joint region;
• directing, by a fiber laser, an energy beam to the joint region to thermally weld the first tubular member to the second tubular member, wherein the energy beam comprises a wavelength of radiation transmittable through the compression sleeve and the first tubular member, and absorbable by the first tubular member and the second tubular member;
• and
• removing the compression sleeve from the joint region.

A method of forming a medical device, comprising:

• positioning at least a portion of a first member adjacent to at least a portion of a second member to define a joint region, wherein the first member comprising a first polymer, and wherein the second member comprising a second polymer;
• positioning a compression sleeve over at least a portion of the joint region;
• directing, by a fiber laser, an energy beam to the joint region to thermally weld the first member to the second member, wherein the energy beam comprises a wavelength of radiation, wherein the wavelength of radiation is transmittable through the compression sleeve and the first member, and wherein the wavelength of radiation is absorbable by the first member and the second member;
• and
• removing the compression sleeve from the joint region.
