A parthenogenetic implant was a medical device which was placed within a patient's body.
In 2365, Captain Jean-Luc Picard received a second replacement artificial heart, a parthenogenetic implant, at Starbase 515 in order to replace the original faulty implant. The cardiac replacement procedure had a very low mortality rate; Van Doren had reduced it to 2.4%.
Some of the risks associated with the procedure included heterocyclic declination and failure of the metabilation occlusions. (TNG: "Samaritan Snare")
