Advanced surgical instrumentation needed for intra-abdominal application of the carbon dioxide laser in reproductive biology.

abstract：:Laser recanalization using metal capped fibers occurs by thermal vaporization of occluding plaque. However, little is known about the effects of blood and flow on the temperature of the laser probe or the arterial wall during lasing. To study this, probe and arterial wall temperatures were measured while a metal cappe...
