Fiber-enhancer

• Known by 22nd century (ENT Novel: Kobayashi Maru)

• 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)

Perscan

• See perscan

Synthetic skin

• Aerosolized organic compound in use by mid-23rd century (DIS Novel: Desperate Hours)
