摘要： A method of forming a tubular body for a catheter, sheath or lead comprises extruding a polymer core having an integrally formed core wall, first lumen, and second lumen, placing a first layer over an outer circumferential surface of the extruded polymer core, and bonding the first layer to the circumferential surface of the extruded polymer cover via a reflow process. The first and second lumens are mandrel free during the reflow process, and a temperature of the reflow process is below a softening point of the polymer core to maintain a collapse free first and second lumen.

摘要翻译： 形成用于导管，护套或导线的管状体的方法包括挤出具有整体形成的芯壁，第一内腔和第二腔的聚合物芯，将第一层放置在挤出的聚合物芯的外周表面上，以及键合 通过回流工艺将挤出的聚合物覆盖层的圆周表面的第一层。 第一和第二流明在回流过程中是无心的，并且回流过程的温度低于聚合物芯的软化点，以保持无崩溃的第一和第二内腔。
