Nanoshell assisted laser soldering of vascular tissue

Lasers in Surgery and Medicine, 2011
AbstractBackground and ObjectivesLaser tissue soldering (LTS) is a promising technique for tissue fusion but is limited by the lack of reproducibility particularly when the amount of indocyanine green (ICG) applied as energy absorber cannot be controlled during the soldering procedure. Nanotechnology enables the control over the quantitative binding of

Optimal laser condition for laser soldering in cream and ring solder

2013 3rd IEEE CPMT Symposium Japan, 2013
This study describes fundamental melting phenomena of ring and cream solder and an evaluation of heat loss in laser soldering. Laser soldering is attractive from the viewpoint of minimum thermal impact on surrounding devices. However, detecting an appropriate laser irradiation condition is difficult since the heat loss is affected by several factors ...
