A specimen retrieval device is provided. The specimen retrieval device includes an applicator. A specimen retrieval pouch operably is disposed within the applicator and deployable therefrom. The specimen retrieval pouch defines a longitudinal axis therethrough and includes a closed bottom portion and an open upper portion. The closed bottom portion includes a plurality of spikes configured to grasp a specimen positioned within the confines closed bottom portion. The upper closed portion includes one or more axial folds that are movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch.

1. A specimen retrieval device, comprising an applicator; anda specimen retrieval pouch operably disposed within the applicator and deployable therefrom, the specimen retrieval pouch defining a longitudinal axis therethrough and including a closed bottom portion and an open upper portion, the closed bottom portion including a plurality of spikes circumferentially disposed on an inner annular wall of the closed bottom portion, the plurality of spikes configured to engage a specimen positioned within the confines of the closed bottom portion when an exterior wall of the specimen retrieval pouch adjacent the closed bottom portion is pulled distally, the open upper portion including at least one axial fold movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch,wherein the applicator includes a handle assembly configured to deploy the specimen retrieval pouch and close the open upper portion of the specimen retrieval pouch. 2. A specimen retrieval device according to claim 1, wherein one of an interior and exterior surface of the specimen retrieval pouch is coated with a lubricious material. 3. A specimen retrieval device according to claim 2, wherein the lubricious material is selected from the group consisting of a hydrogel gel and polytetrafluoroethylene. 4. A specimen retrieval device according to claim 2, wherein the lubricious material provides a friction coefficient that ranges from about 0.003 to about 0.09. 5. A specimen retrieval device according to claim 1, wherein the open upper portion includes at least two axial folds. 6. A specimen retrieval device according to claim 5, wherein the at least two axial folds include an outer axial fold and an inner axial fold, wherein a force needed to move the outer axial fold from a folded configuration to an unfolded configuration is less than a force needed to move the inner axial fold from a folded configuration to an unfolded configuration. 7. A specimen retrieval device according to claim 1, wherein the predetermined force is a pulling force that is applied to the bottom portion of the specimen retrieval pouch, the pulling force being applied in a generally parallel orientation with respect to the longitudinal axis of the specimen retrieval pouch. 8. A specimen retrieval device according to claim 1, wherein a length of an unfolded specimen retrieval bag is proportional to the number of axial folds. 9. A specimen retrieval device, comprising an applicator including a handle assembly having an actuator; anda specimen retrieval pouch operably disposed within the applicator and deployable therefrom when the actuator is moved distally, the specimen retrieval pouch defining a longitudinal axis therethrough and including a closed bottom portion and an open upper portion, the closed bottom portion including a plurality of spikes circumferentially disposed on an inner annular wall of the closed bottom portion, the plurality of spikes configured to engage a specimen positioned within the confines therein when an exterior wall of the specimen retrieval pouch adjacent the closed bottom portion is pulled distally, the open upper portion including at least one axial fold movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch,wherein the actuator is configured to translate relative to a shaft member in order to deploy the specimen retrieval pouch from a stored rolled configuration to a freely expanded configuration. 10. A specimen retrieval device according to claim 9, wherein one of an interior and exterior surface of the specimen retrieval pouch is coated with a lubricious material. 11. A specimen retrieval device according to claim 10, wherein the lubricious material is selected from the group consisting of a hydrogel and polytetrafluoroethylene. 12. A specimen retrieval device according to claim 10, wherein the lubricious material provides a friction coefficient that ranges from about 0.003 to about 0.09. 13. A specimen retrieval device according to claim 9, wherein the open upper portion includes at least two axial folds. 14. A specimen retrieval device according to claim 13, wherein the at least two axial folds include an outer axial fold and an inner axial fold, wherein a force needed to move the outer axial fold from a folded configuration to an unfolded configuration is less than a force needed to move the inner axial fold from a folded configuration to an unfolded configuration. 15. A specimen retrieval device according to claim 9, wherein the predetermined force is a pulling force that is applied to the bottom portion of the specimen retrieval pouch, the pulling force being applied in a generally parallel orientation with respect to the longitudinal axis of the specimen retrieval pouch. 16. A specimen retrieval device according to claim 9, wherein a length of an unfolded specimen retrieval bag is proportional to the number of axial folds. 17. A specimen retrieval device, comprising an applicator; anda specimen retrieval pouch operably disposed within the applicator and deployable therefrom, the specimen retrieval pouch defining a longitudinal axis therethrough and including a closed bottom portion and an open upper portion, the closed bottom portion including a plurality of retention features circumferentially disposed on an inner annular wall of the closed bottom portion, the plurality of retention features configured to engage a specimen positioned within the confines of the closed bottom portion when an exterior wall of the specimen retrieval pouch adjacent the closed bottom portion is pulled distally, the open upper portion including at least one axial fold movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch,wherein the applicator includes a handle assembly configured to deploy the specimen retrieval pouch and close the open upper portion of the specimen retrieval pouch.
