Laparoscopic apparatus and method for insertion into a space or potential space in a body comprising an introducer device having a tubular member with a bore extending therethrough. A tunneling shaft assembly is provided and is slidably mounted in the bore of the introducer device. The tunneling shaft assembly includes a tunneling shaft having proximal and distal extremities. A tunneling member is mounted on the distal extremity of the tunneling shaft. A balloon assembly is provided which is removably secured to the tunneling shaft. The balloon assembly includes a balloon wrapped about said tunneling shaft. A sheath is provided which encloses the balloon on the tunneling shaft. The sheath has a slit extending longitudinally thereof permitting the sheath to be removed whereby the balloon can be released and inflated. A tubular member is provided which has a balloon inflation lumen thereon and is coupled to the balloon for inflating said balloon.

A method for creating an anatomic operating space in tissue by dissection of the tissue along a natural plane of separation by use of a rigid member having a distal extremity and a deflated inflatable balloon carried by the rigid member, comprising making an incision in the body to expose the natural separation plane, introducing the rigid member into the incision and into the tissue to cause dissection of the tissue along the natural separation plane so that the deflated balloon is disposed in the natural separation plane inflating the balloon to cause further dissection of tissue along the natural separation plane, to provide the anatomic operating space, deflating the balloon, removing the balloon from the anatomic operating space, inflating the anatomic operating space with a gas, performing a surgical procedure in the inflated anatomic operating space and deflating the anatomic operating space. 5. A method for creating an anatomic operating space in tissue by dissection of the tissue along a natural plane of separation by use of a member having a blunt distal extremity, a deflated inflatable balloon carried by the blunt member and enclosed by a removable sheath, comprising making an incision in the body to expose the natural separation plane, introducing the member having a blunt distal extremity into the incision and into the tissue to cause dissection of the tissue along the natural separation plane, removing the removable sheath so that the deflated balloon is disposed in the natural separation plane, inflating the balloon to cause further dissection of tissue along the natural separation plane to provide the anatomic operating space, deflating the balloon, removing the balloon from the anatomic operating space, inflating the anatomic operating space with a gas, performing a surgical procedure in the inflated anatomic operating space and deflating the anatomic operating space. 6. A method for creating a preperitoneal space in a body having an abdominal cavity with an abdominal wall and a peritoneum overlying the abdominal cavity, the abdominal wall and the peritoneum being adjacent to each other and being interconnected by tissue forming a natural separation plane and a preperitoneal area overlying the peritoneum, comprising making an incision in the abdominal wall opening into the preperitoneal area, introducing a balloon in a deflated condition into the incision and into the preperitoneal area, inflating the balloon to cause dissection of the tissue in the preperitoneal area along the natural separation plane to create a dissected preperitoneal space, deflating the balloon, removing the deflated balloon and inflating the dissected space with a gas. 7. A method for providing access for repairing a hernia without penetrating the peritoneum underlying the abdominal wall and being connected thereto by tissue forming a natural separation plane, comprising providing an inflatable balloon, placing the balloon between the peritoneum and the abdominal wall, inflating the balloon to dissect the tissue along the natural plane to provide a dissected preperitoneal space, deflating the balloon, removing the deflated balloon and inflating the dissected space with a gas. 8. A method for creating an anatomic operating space in tissue by dissection of the tissue along a natural plane of separation by use of a rigid member having a distal extremity, a deflated inflatable balloon carried by the member, comprising making an incision in the body to expose the natural separation plane, introducing the member into the incision and into the tissue to cause dissection of the tissue along the natural separation plane so that the deflated balloon is disposed in the natural separation plane, inflating the balloon to cause further dissection of tissue along the natural separation plane to provide the anatomic operating space, deflating the balloon, removing the deflated balloon and inflating the anatomic operating space with a gas. 9. A method for creating an anatomic operating space in tissue by dissection of the tissue along a natural plane of separation by use of a member having a blunt distal extremity, a deflated inflatable balloon carried by the blunt member, and enclosed by a removable sheath, comprising making an incision in the body to expose the natural separation plane, introducing the member having a blunt distal extremity into the incision and into the tissue to cause dissection of the tissue along the natural separation plane, removing the removable sheath so that the deflated balloon is disposed in the natural separation plane, inflating the balloon to cause further dissection of tissue along the natural separation plane to provide the anatomic operating space, deflating said balloon, removing said deflated balloon and inflating said anatomic operating space with a gas. 10. A method for a laparoscopic hernia repair through the preperitoneal space in a body having an abdominal area with an abdominal wall and a preperitoneal area underlying the abdominal wall, comprising making an incision in the abdominal wall into the preperitoneal area, introducing an inflatable balloon in a deflated condition into the incision and into the preperitoneal area, inflating the balloon to create a dissected preperitoneal space, deflating the balloon, removing the balloon from the dissected preperitoneal space, inflating the dissected preperitoneal space with a gas, introducing a graft into the dissected preperitoneal space and positioning the graft so that it overlies the area of the hernia, and deflating the dissected preperitoneal space while permitting the graft to remain in contact with the area of the hernia in general alignment with the hernia to provide reinforcement for the abdominal wall in the area of the hernia. 11. The method of claim 10 wherein the step of introducing a hernia graft into the dissected preperitoneal space includes providing a graft with a central portion having a biodegradable anchoring tip secured thereto, and positioning the graft so that the tip is in alignment with the inguinal ring and can be maneuvered into the inguinal ring for anchoring to bring the graft into contact with the inguinal floor and the overlying tissue. 12. The method of claim 10 wherein the step of providing a graft includes the steps of providing an additional balloon in a rolled up configuration with the graft being disposed on one side of the additional balloon, introducing the rolled up balloon into the dissected preperitoneal space, positioning the roll in the desired location, and inflating the additional balloon to cause said additional balloon to unroll to place the graft in the vicinity of the hernia. 13. The method of claim 12 including the step of causing the rolled up balloon to unroll in one direction as the balloon is being inflated.
