Medical technology
Delta wave inducer
- Sleep aid used to directly produce a state of sleep in a patient in order to aid healing via stimulating the production of delta waves in the brain (DS9: "The Passenger", "Invasive Procedures"; DS9 Novel: Mission Gamma: Cathedral)
- Mistakenly referred to as an alpha wave inducer in "The Passenger", but alpha waves are associated with wakefulness
Exoscalpel
- High-precision version of a laser scalpel for more precise surgeries (TNG: "Ethics"; VOY: "Message in a Bottle"; DS9 Novel: Mission Gamma: Cathedral)
Fiber-enhancer
- Known by 22nd century (ENT Novel: Kobayashi Maru)
- Presumably used to improve nerve conductivity or functionality (ENT Novel: Kobayashi Maru)
Laser scalpel
- Standard laser-based low-precision medical cutting tool (TNG: "The Host"; DS9: "Invasive Procedures", "The Alternate"; VOY: "Dark Frontier", "Imperfection"; TNG Novel: Vendetta)
- Exoscalpel used instead for high precision tools
Microscalpel
- Known by 22nd century (ENT Novel: Kobayashi Maru)
- Presumably hand-wielded cutting implement used for microsurgery (ENT Novel: Kobayashi Maru)
