Specimen retrieval device
First Claim
1. A specimen retrieval pouch deployable from an applicator, the specimen retrieval pouch comprising:
- a closed bottom portion defining a first cavity; and
an open upper portion connected to the closed bottom portion and defining a second cavity in communication with the first cavity, the closed bottom portion and the open upper portion collectively defining a central longitudinal axis through the first and second cavities, the open upper portion including;
a first portion defining a first fold; and
a second portion defining a second fold;
wherein the first fold is coupled to the second fold by a first coupling and the second fold is coupled to the pouch by a second coupling, the first coupling being such that a first threshold pull force is required to move the first fold from a folded state to an unfolded state and the second coupling being such that a second threshold pull force is required to move the second fold from a folded state to an unfolded state, the first threshold pull force being less than the second threshold pull force such that upon application of the first threshold pull force on the open upper portion, the first portion moves to the unfolded state and the second portion remains in the folded state.

Abstract
A specimen retrieval device includes an applicator. A specimen retrieval pouch is operably 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.

8. A specimen retrieval pouch deployable from an applicator, the specimen retrieval pouch comprising:
-
a closed bottom portion defining a first cavity; and an open upper portion defining a second cavity in communication with the first cavity, the closed bottom portion and the open upper portion collectively defining a central longitudinal axis through the first and second cavities, the open upper portion including; a first portion coupled to the closed bottom portion, the first portion configured to move from a folded state to an unfolded state in response to a first threshold force applied to the specimen retrieval pouch in a direction parallel with the central longitudinal axis; and a second portion coupled to the first portion, the second portion configured to move from a folded state to an unfolded state in response to a second threshold force applied to the specimen retrieval pouch in the direction parallel with the central longitudinal axis, the first and second threshold forces being different from one another, wherein the first portion includes; an annular first wall coupled to the closed bottom portion; and an annular second wall concentrically disposed within the first wall and coupled to the first wall. - View Dependent Claims (9)

10. A specimen retrieval pouch deployable from an applicator, the specimen retrieval pouch comprising:
-
a closed bottom portion defining a first cavity; and an open upper portion defining a second cavity in communication with the first cavity, the closed bottom portion and the open upper portion collectively defining a central longitudinal axis through the first and second cavities, the open upper portion configured to move between a folded state and an unfolded state and including; a first portion including a first fold disposed about the central longitudinal axis and coupled to the closed bottom portion; and a second portion including a second fold disposed about the central longitudinal axis and coupled to the first portion the first and second folds being coupled to one another by adhesives such that upon application of a first threshold force to the specimen retrieval pouch in a direction parallel with the central longitudinal axis, the first portion will unfold and upon application of a second threshold force to the specimen retrieval pouch in the direction parallel with the central longitudinal axis, the second portion will unfold, wherein the adhesives are selected such that the first and second threshold forces are different. - View Dependent Claims (11, 12, 13, 14, 15, 16)
