Patent ID: 8585858

Claim:
A method of manufacturing a medical catheter having an intermediate zone, a bump tubing transition zone, and a distal zone, the method comprising the steps of: fitting a distal liner tube to a mandrel; swaging a plurality of radiopaque markers over the distal liner tube in the distal zone; fitting a distal cover tube over the distal liner tube and radiopaque markers in the distal zone; placing a shrink tubing segment over the distal cover tube; heating the shrink tubing segment to compress the distal cover tube onto the distal liner tube; removing the shrink tubing segment fitting a bump tubing onto the mandrel to abut both the distal liner tube and the distal cover tube; and further comprising the step of bonding the bump tubing to the distal liner tube and the distal cover tube at an abutment; placing a second shrink tubing segment over the abutment of the bump tubing with the distal liner tube and the distal cover tube; heating the second shrink tubing segment during the bonding of the bump tubing with the distal cover tube and the distal liner tube; and removing the second shrink tubing segment.
