Multilumen catheters and method of manufacturing
First Claim
Patent Images
1. A method of making a multilumen catheter assembly, comprising:
- providing a plurality of tubes, each tube having a first end, a second end, at least one lumen extending longitudinally through at least a portion of each tube, an inner surface and an outer surface;
selectively heating by contact a first portion of a first tube, wherein the heating consists of heating a first inner surface of the first portion; and
contacting the selectively heated portion of the inner surface of the first tube with at least a second portion of a second tube, the second portion consisting of a second inner surface, to form a multilumen catheter shaft that is joined together along at least a portion of the length of the catheter shaft.
