A tactical device holster system is described that is a complete carry and deployment solution allowing for split-second deployment of hand-held non-lethallethal deployable devices by tactical personnel. The apparatus is inserted at a catheter site and is then positioned through the lumen of the blood vessel to a remote anastomosis site. The first electrode including a nano-metal transparent conductive layer is disposed on a transparent substrate. The locking tongue is releasably retained in the retained position against biasing force of the biasing element. The non-linear pre-fusion electric field waveforms can change in a stepped way, in a continuous way, in a sigmoidal way, with step-wise increasing waveforms in adjacent steps, with step-wise increasing waveforms in non-adjacent steps, and in accordance with non-linear algorithms.
