A hollow, long, tubular electrical conductor with a sharply-pointed distal end intended for percutaneous introduction within soft tissue to deliver short electrical pulses, in a monopolar configuration, to produce irreversible cell membrane electroporation ...
A hollow, long, tubular electrical conductor with a sharply-pointed distal end intended for endoscopic introduction to deliver short electrical pulses, in a monopolar configuration, to produce irreversible cell membrane electroporation for ablation of soft ...
An individual hollow-bore cylinder made of a dense material, e.g., lead (Pb), tungsten (W) or titanium (Ti), used to ensure that only gamma ray activity directly in front of the collimator channel reaches the scintillation crystal of the imaging or detector...
