Abstract

Systems and methods for tissue containment and retrieval are disclosed. The containment system includes a primary chamber interconnected with a secondary channel extending from the primary chamber. A tissue specimen is mobilized inside a body cavity and placed into the primary chamber through a first opening. The first opening is pulled through a first incision or orifice and the narrower secondary channel is placed at a second incision or orifice. A second opening at the end of the secondary channel permits observation via a scope inserted through the second opening of the tissue specimen in the primary chamber undergoing morcellation via the first opening. Other systems and methods for deployment, containment, debulking and sealing of the second opening to create a closed system for the safe retrieval of the tissue specimen are provided.

First claim

We claim:

1. A tissue containment bag, comprising:
a first opening and a second opening interconnected by a sidewall of flexible material;
the sidewall defining a first interior compartment configured for receiving a tissue specimen through the first opening into the first interior compartment;
the sidewall forming an elongated hollow, sleeve-like neck extension defining a second interior compartment having a proximal end interconnected with the first interior compartment and a distal end interconnected with the second opening; the second opening being in fluidic communication with the second interior compartment; the second interior compartment being in fluidic communication with the first interior compartment and the first interior compartment being in fluidic communication with the first opening;
the proximal end of the neck extension being connected to the sidewall of the first interior compartment at a first side; the neck extension extendable laterally in a direction away from the first side; and
an external pocket provided on an outer surface of the sidewall adjacent to an entryway intersection between the first interior compartment and the second interior compartment, said external pocket is sized and configured to contain the neck extension in a folded configuration.

2. The tissue containment bag of claim 1 further including a first ring connected to the sidewall at the first opening and configured to keep the first opening in an open configuration; and a second ring connected to the neck extension at the second opening and configured to keep the second opening in an open configuration; wherein at least one of the first ring and second ring is resiliently compressible into a low profile configuration.

3. The tissue containment bag of claim 1 wherein the diameter of the neck extension is constant from the proximal end to the distal end.

4. The tissue containment bag of claim 1 further including a tether connected to the sidewall along a length of at least a portion of the neck extension.

5. The tissue containment bag of claim 1 further including a tether connected to the sidewall and extending along the neck extension from the second opening to the proximal end of the neck extension.

6. The tissue containment bag of claim 1 further including a tether connected to the sidewall extending from the second opening along a top portion of the neck extension to the proximal end of the neck extension and upwardly along a length of the sidewall to the first opening.

7. The tissue containment bag of claim 1 further including a tether connected to the sidewall along a top length of at least a portion of the neck extension.

8. The tissue containment bag of claim 1 wherein the first interior compartment comprises a base defining the first side and a second side relative to the first opening and the base; wherein the neck extension is formed at various positional locations with respect to the first side and the base.

9. The tissue containment bag of claim 8 wherein the intersection of the neck extension is contiguous with the base or is at the base.

10. The tissue containment bag of claim 1 wherein a first longitudinal axis is defined by a radial plane of the first opening when the bag is in an undeflected configuration; a second longitudinal axis being defined by a radial plane of the second opening when in the undeflected configuration; the first and second longitudinal axes being parallel or angled with respect to each other.

11. The tissue containment bag of claim 10 wherein the sidewall at the first interior compartment has a width perpendicular to the first longitudinal axis and a length along the first longitudinal axis; the neck extension having a width perpendicular to the second longitudinal axis and a length along the second longitudinal axis; the width of the neck extension being smaller than the width of the first interior compartment.

12. The tissue containment bag of claim 1 wherein the entryway intersection is defined by the proximal end of the neck extension at the first interior compartment.

13. The tissue containment bag of claim 1 further comprising a perforation located between the neck extension and the first side to retain the neck extension in a configuration for delivery; the perforation being configured to detach at least a portion of the neck extension into an extended deployed configuration.

14. The tissue containment bag of claim 1 wherein the sidewall forms an elongated hollow, sleeve-like second neck extension defining a third interior compartment having a proximal end interconnected with the first interior compartment and a distal end interconnected with a third opening; the third opening being in fluidic communication with the first interior compartment.

15. A tissue containment bag, comprising:
a first opening and a second opening interconnected by a sidewall of flexible material;
the sidewall defining a first interior compartment configured for receiving a tissue specimen through the first opening into the first interior compartment;
the sidewall forming an elongated hollow, sleeve-like neck extension defining a second interior compartment having a proximal end interconnected with the first interior compartment and a distal end interconnected with the second opening; the second opening being in fluidic communication with the second interior compartment; the second interior compartment being in fluidic communication with the first interior compartment and the first interior compartment being in fluidic communication with the first opening;
the proximal end of the neck extension being connected to the sidewall of the first interior compartment at a first side; the neck extension extendable laterally in a direction away from the first side;
wherein the neck extension includes a sealing mechanism for sealing off the second opening by rolling a resilient ring connected to the sidewall at the second opening, said sealing mechanism comprises a first pocket having a first pocket mouth and a second pocket having a second pocket mouth, wherein the first and second pockets are connected to an outer surface of the neck extension such that the first pocket mouth faces the second pocket mouth.

16. The tissue containment bag of claim 15 wherein the first pocket mouth faces the proximal end of the neck extension on one side of the neck extension.

17. The tissue containment bag of claim 16 wherein the second pocket mouth faces the distal end of the neck extension on an opposite side of the neck extension; the second pocket being located distally from the first pocket; the first and second pockets being sized and configured to receive at least a portion of the distal end of the neck extension.

18. The tissue containment bag of claim 15 wherein the resilient ring is compressible into a low profile configuration.

19. The tissue containment bag of claim 15 wherein the proximal end of the neck extension at the first interior compartment defines an entryway intersection between the first interior compartment and the second interior compartment.

20. The tissue containment bag of claim 15 wherein the first interior compartment comprises a base defining the first side and a second side relative to the first opening and the base; wherein the neck extension is formed at various positional locations with respect to the first side and the base.
