A tissue retrieval method comprising:
- providing a retrieval bag having an open end and a bag wall extending to a closed end;
- positioning the retrieval bag in a body cavity of a patient;
- disposing a tissue specimen in the retrieval bag;
- withdrawing the open end of the retrieval bag through an access incision accessing the body cavity;
- and
- lifting a plurality of lifting members carried in the bag wall to thereby lift the closed end of the retrieval bag and the tissue specimen into the access incision to facilitate cutting the tissue specimen.

A method for retrieving a specimen, comprising:
- positioning a retrieval bag within a body of an individual, the retrieval bag comprising a rim disposed circumferentially about an open end of the retrieval bag and a bag wall extending to a closed end, the bag wall carrying a plurality of lifting members;
- disposing the specimen in the retrieval bag;
- withdrawing the open end of the retrieval bag out of the body;
- withdrawing the plurality of lifting members away from the rim to thereby lift the closed end of the retrieval bag toward the open end.

A method of using a retrieval system, comprising:
- introducing an elongate sleeve into a body cavity of an individual, the elongate sleeve having a retrieval bag in a pre-deployed configuration disposed therein, the retrieval bag comprising an open end having a rim portion and a bag wall extending to a closed end;
- deploying the retrieval bag within the body cavity such that the retrieval bag assumes a deployed configuration;
- capturing a specimen in the retrieval bag;
- removing the open end of the retrieval bag from the body cavity;
- lifting a plurality of lifting elements carried within the bag wall away from the rim portion, thereby raising the closed end of the retrieval bag toward the open end.
