OBJECTIVE: To determine any loss of function of a single-use bipolar vessel sealing device after repeated sterilization and use on canine carotid arteries.
STUDY DESIGN: Ex vivo; randomized block design (dog).
SAMPLE POPULATION: Carotid artery segments (n = 90) from 15 canine cadavers.
METHODS: Six 10-mm LigaSure Atlas 20 cm devices (Covidien Inc, Minneapolis, Minnesota) were used to seal canine carotid artery segments in one cadaver, then resterilized using ethylene oxide and reused in a second cadaver, and so on, for a total of 15 uses/15 cadavers per LigaSure. Sealing times and bursting pressures of each carotid artery segment after each use were recorded. Charring and sticking at each seal location was qualitatively assessed.
RESULTS: Mean (SD) sealing time for all segments was 5.3 (1.4) seconds, ranging from 2.7 to 9.5 seconds. There was no significant change in sealing time for successive uses (P = .117). The mean (SD) bursting pressure for all segments was 1041.3 (316.7) mm Hg, ranging from 355 to 1555 mm Hg. There was no change in bursting pressure across uses (P = .57). Moderate sticking and charring occurred at each time point but was not subjectively different throughout the study.
CONCLUSION: The LigaSure Atlas vessel sealing device can be used and resterilized with ethylene oxide up to 15 times with no change in sealing time or bursting pressure of the seal.
