A dissector/retractor device (10) comprising a balloon (12) having a deflated state, and an inflated state, is described for performing minimally invasive surgical procedures by creating a tunnel alongside a target tissue in the body. The balloon (12) in its inflated state forms an open space (16) extending transversely through the balloon (12). The balloon (12) is carried by an insertion assembly (14). The balloon (12) may be an elongate torus shape with an elongate open area in its interior. The insertion assembly includes a blunt dissection device, and a handle (22). In use, the dissector/retractor is inserted through a small incision, and bluntly tunneled (10) through body tissue to a desired location. The balloon (12) is inflated to create a space in the body tissue, and may also dissect tissue as necessary away from the tissue to be treated. The balloon (12) is left in place inflated to retract the space. Another incision may be made to provide more direct access to the target tissue than the original incision. The target tissue may then be diagnosed and/or treated through the direct access incision, through the overlying tissue, through the open space (16) in the balloon (12).

L'invention concerne un dissecteur/écarteur (10) pourvu d'un ballonnet (12) pouvant se trouver à l'état dégonflé ou à l'état gonflé, qui permet d'effectuer des interventions chirurgicales peu invasives en créant un tunnel à l'intérieur d'un tissu cible de l'organisme. A l'état gonflé, le ballonnet (12) forme un espace ouvert dirigé transversalement. Il est porté par un ensemble d'insertion (14). Il peut avoir une forme torique allongée avec, à l'intérieur, une surface ouverte allongée. L'ensemble d'insertion comprend un dispositif de dissection mousse et une poignée (22). En utilisation, on introduit le dissecteur/écarteur à travers une petite incision et on le pousse de façon à former un tunnel mousse à l'intérieur du tissu jusqu'à l'emplacement désiré. On gonfle le ballonnet (12) afin de former un espace à l'intérieur dudit tissu et de disséquer ce dernier de façon à l'écarter autant que nécessaire du tissu à traiter. On le laisse en place gonflé de façon à maintenir ouvert ledit espace. On peut pratiquer une autre incision pour créer un accès au tissu cible plus direct que la première incision. On peut alors poser un diagnostic concernant le tissu et/ou traiter celui-ci à travers l'incision d'accès direct, le tissu sus-jacent et l'espace ouvert à l'intérieur du ballonnet (12).
