摘要：
A method and apparatus is provided for forming a fusion bond between two materials such as two components of a catheter. The method begins by forming a bond site by positioning a portion of a first body with respect to a portion of a second body so that a fusion bond site is formed. A laser beam is generated that has an intensity profile across its width. The laser beam is directed onto at least a portion of the first and second bodies within the bond site so that a fusion zone having an increased temperature is formed. After the laser beam is generated, the intensity profile of the laser beam that is directed onto the bond site is controllably adjusted by an optical element such as a dynamically-adjustable beam shaping element.
摘要（中）：
提供了一种用于在诸如导管的两个部件的两种材料之间形成熔接的方法和装置。 该方法开始于通过将第一主体的一部分相对于第二主体的一部分定位，从而形成熔合点位置来形成粘合部位。 产生在其宽度上具有强度分布的激光束。 激光束被引导到粘结位置内的第一和第二体的至少一部分上，从而形成具有升高的温度的熔融区。 在产生激光束之后，通过光学元件（例如动态可调整的光束整形元件）可控地调节被引导到粘结部位上的激光束的强度分布。
