A multifunctional device for use in endoscopic operative procedures includes a loop forming portion for being introduced in the body and being movable, from externally of the body, from a non-deployed position to a deployed position to form a loop structure for performing various functions including collecting substances. The loop forming portion is squeezable to squeeze collected substances into a collection bag prior to withdrawal of the loop forming portion from the body. The collection bag is movable between a non-expanded position facilitating introduction in the body and an expanded position within the body to receive the loop forming portion. A method of facilitating the performance of endoscopic procedures includes the steps of introducing the loop forming portion in the body through a narrow portal, moving the loop forming portion from the non-deployed position to the deployed position, performing an operative procedure with the loop forming portion and moving the loop forming portion to the non-deployed position for withdrawal from the body. |
