Abstract: A detector detects thermal radiation being emitted from a fusion bond site while a laser beam impinges on and heats at least a portion of the bond site. The detector can provide an electrical signal to a signal processor for controllably adjusting the laser beam power. The electrical signal may be substantially correlated to the temperature of at least a region of the bond site. A workpiece support preferably positions a first and second polymeric body so that a fusion bond site is formed. The laser impinges on at least a portion of the fusion bond site such that it emits thermal radiation. The detector senses the thermal radiation and preferably provides a signal to the signal processor. In an aspect of the present invention, the signal processor controllably adjusts the power of the laser beam based on the signal provide by the detector.

Abstract: A detector (30) detects thermal radiation (28) being emitted from a fusion bond site (26) while a laser beam (14) impinges on and heats at least a portion of the bond site. The detector (30) can provide an electrical signal to a signal processor for controllably adjusting the laser beam power. The electrical signal may be substantially correlated to the temperature of at least a region of the bond site. A workpiece support preferably positions a first (20) and second (22) polymeric body so that a fusion bond site is formed. The laser impinges on at least a portion of the fusion bond site such that it emits thermal radiation. The detector (30) senses the thermal radiation and preferably provides a signal to the signal processor. In an aspect of the present invention, the signal processor controllably adjusts the power of the laser beam based on the signal provide by the detector.

Abstract: A process for laser joining a first metal, having a first reflectance curve as a function of wavelength, such as nitinol or stainless steel, and a second metal, having a second reflectance curve, such as gold. The process comprises placing the first and second metals in contact with one another then exposing at least one of the first metal and second metal to a laser beam having a wavelength selected from an optimal range of wavelengths over which the reflectance curves of the two metals essentially overlap. The first metal may comprise a first metal element having a sufficiently low heat sink capacity and a sufficiently lesser reflectance than the second metal at wavelengths outside the optimal range of wavelengths such that laser joining at such wavelengths exposes the first metal to a risk of excessive melting, vaporization, or cutting through the first metal element. The first metal element may be a stent adapted for endoluminal deployment, wherein the second metal is a radiopaque marker relative to the first metal. A stent produced by this process may comprise one or more first metal elements with a radiopaque marker metal attached to one or more portions of at least one element, the radiopaque marker comprising the second metal attached to the first metal by a weld, a clad layer of the second metal over the first metal, or an alloy layer of the two metals over the first metal.
