Patent ID: 7763827

Claim:
A method of laser welding to form a weld seam along a junction between metal coated polymer members suitable for use as part of an implantable medical device, comprising: defining a single weld path along the junction between the metal coated polymer members; locating a plurality of initial welding locations spaced along the single weld path; delivering a first sequence of pulses of laser beam energy, each pulse in the first sequence of pulses being directed to each of the plurality of initial welding locations to form a first sequence of a plurality of weld points of the metal coated polymer members at the plurality of initial welding locations; and delivering successive sequences of pulses of laser beam energy, the pulses in each successive sequence of pulses each being directed to each of the plurality of weld points located along the single weld path an incremental distance from each of the existing weld points to form successive sequences of weld points of the metal coated polymer members, the sequences continuing until the weld points form a generally continuous weld seam of the metal coated polymer members along the single weld path.
