ABSTRACT:
A surgical method comprises the steps of (a) piercing an abdominal wall of a patient to form an opening in the wall, (b) inserting a tubular member through the opening, (c) pushing a inert flexible membrane through the tubular member and into a body cavity of the patient, (d) opening the injected membrane from a collapsed configuration into an at least partially opened configuration, (e) juxtaposing the membrane and an internal organ part of the patient, (f) closing the membrane about the body organ part upon juxtaposition of the membrane and the organ part, and (g) drawing the membrane, together with the enclosed organ part, from the patient's body cavity through the tubular member. An associated surgical kit comprises a tubular member insertable through an opening in an abdominal wall of a patient and a flexible membrane disposed in a collapsed configuration at least partially inside the tubular member. An ejection member is provide for pushing the membrane out of the tubular member into an internal body cavity of the patient. Elongate filaments are connected to the membrane through the tubular member for closing the membrane about a body organ part upon a juxtaposition of the organ part and the membrane and for pulling the membrane from the patient's body cavity through the tubular member.
