“…This contrasts with work described by other researchers, who have designed systems that appear to nicely provide liver retraction, but utilize a much larger external magnet [17,18], which may prove cumbersome. Indeed, the agility of our system has allowed us to perform a wide array of complex surgical tasks using magnetic instruments, including dissection, cauterization, optics delivery, as well as retraction [2][3][4][5][6][7][8][9][10][11].…”

“…This system includes deployable instruments (camera, light source, grasper, retractor, and cautery dissector) that are inserted into the abdominal cavity through a single access point (laparoscopically, NOTES or LESS) [2][3][4][5][6][7][8][9][10][11]. The internal components contain magnets and are manipulated by using an external magnet, which is held on the surface of the abdominal wall.…”

“…This platform was originally conceived for laparoscopic applications with the purpose of minimizing the number of incisions required and enhancing range of motion [2,4,5,7]. Additionally, the possibility of remote instrument insertion makes the MAGS platform quite attractive for NOTES applications [3,6,8,10,11].…”

“…We previously reported successful NOTES transvaginal cholecystectomy and nephrectomy and LESS nephrectomy using MAGS instruments in both acute and survival porcine models [3,4,6,10]. However, maximum abdominal wall thickness in these procedures measured 2.5 cm; it is likely that thicker abdominal walls may be encountered in adult human patients.…”

“…Subsequent work has furthered research using the MAGS tool-suite for general surgical and NOTES applications. 22,25,26 Several generations of MAGS cameras, tissue retractors, and cauterizer instruments have been successfully deployed via transabdominal and NOTES (transgastric, transcolonic, and transvaginal) approaches for use in a porcine cholecystectomy model. In all cases, the gallbladder has been successfully dissected free from the liver attachments using only the MAGS cauterizer.…”

Evolution of minimally invasive techniques has generated an impetus in the surgical community to reduce the invasiveness of laparoscopic surgery. To achieve this goal, surgeons are either limiting the number of transabdominal trocars using laparoendoscopic single site surgery (LESS) or eliminating them completely using natural orifice translumenal endoscopic surgery (NOTES). The principle challenge with LESS or NOTES procedures is loss of triangulation, reduction in instrument working envelopes, and collision of conventional laparoscopic instrumentation. To overcome these limitations, surgical innovations, such as the use of deployable intracorporeal instrumentations, are necessary. Magnetic anchoring and guidance system (MAGS) technology is one approach for deployable instrumentation whereby intra-abdominal instruments can be maneuvered by the use of an external handheld magnet. Such a strategy would permit a single access port (either transabdominal or via a natural orifice) to serve as an entry point for multiple instruments. MAGS technology has thus far developed to incorporate instruments such as retractors, an intra-abdominal camera, and cautery dissectors. Continuous instrument development and rapid prototyping have created more robust MAGS platforms while potentially obviating the need for laparoscopic assistance. Animal work to date is promising with successful completion of a single-port nephrectomy as well as a NOTES transvaginal cholecystectomy in both nonsurvival and survival porcine models. As with all new technology, there will be an associated learning curve for these MAGS techniques that will necessitate more thorough elucidation before widespread use. The development of magnetically controlled and anchored intracorporeal surgical instruments, retractors, and cameras may advance surgical practice and improve patient care while meeting or exceeding the benefits of current-day fixed-trocar laparoscopy.
