Autosuture
The autosuture was a medical tool, descended from the 20th century suture, that was used as early as the 22nd century. By the late 24th century, this technology was laser-based. () 

The function of the autosuture was to seal closed and promote the healing of wounds from surgery or deep trauma by stimulating the patient's own anabolism. It was used in situations where the dermal regenerator was inadequate.

Doctor Phlox used an autosuture during his operation on Porthos in 2152. It was used to secure the placement of the pituitary gland he transplanted from a Calrissian chameleon. () Shortly thereafter, he traded his autosuture, among other things, for deuterium. ()

Dr. Beverly Crusher used an autosuture to treat Captain Jean-Luc Picard after he was stabbed in the  by Jono. ()

Dr. Julian Bashir used an autosuture to repair an injury to Martok's shoulder, sustained during a training exercise with Worf. While the repair was general, had the wound been three centimeters to the right, Martok's brachial artery would have been severed, causing much greater damage than an autosuture could repair. ()
