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.

Claims (30)

1 . A method comprising the steps of:

providing a tissue containment bag for deployment and removal of a tissue specimen inside a body cavity; the tissue containment bag having 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 neck extension extending laterally outwardly from the first interior compartment when in an extended deployed configuration;

placing the tissue containment bag into a low-profile delivery configuration for facilitating percutaneous insertion; and

converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration,

wherein the step of placing the tissue containment bag into a low-profile delivery configuration comprises retaining the neck extension in a retracted configuration using a retainer.

2 . The method of claim 1 wherein, in the retracted configuration, the neck extension is held proximate to the first interior compartment or within an external pocket.

3 . The method of claim 1 wherein the step of converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration comprises placing the neck extension from the retracted configuration to the extended deployed configuration after deployment inside the body cavity.

4 . The method of claim 1 further comprising the step of providing an external pocket on the sidewall of the tissue containment bag; the external pocket serving as the retainer and being sized and configured to contain the neck extension in a folded configuration.

5 . The method of claim 4 wherein the step of placing the tissue containment bag into a low-profile delivery configuration comprises folding the neck extension and placing the neck extension in the folded configuration inside the external pocket.

6 . The method of claim 5 wherein the step of converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration comprises removing the neck extension from the external pocket to place the neck extension in the extended deployed configuration, wherein the removing step is performed using a surgical instrument or by pulling a tether connected to the neck extension and extending freely beyond the distal end of the neck extension.

7 . The method of claim 1 further comprising the step of providing a perforation on the sidewall located between the neck extension and the first interior compartment; the perforation serving as the retainer and extending downwardly such that the first opening remains interconnected to the second opening while retaining the neck extension in the retracted configuration.

8 . The method of claim 7 wherein the step of converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration comprises perforating the perforation to detach at least a portion of the neck extension.

9 . The method of claim 8 wherein the perforating step is performed using a surgical instrument or by pulling a tether located along the perforation or at the second opening of the tissue containment bag.

10 . The method of claim 1 further comprising the step of providing at least one clip to retain the neck extension in a vicinity of the first interior compartment at a first side of the tissue containment bag and to serve as the retainer.

11 . The method of claim 10 wherein the step of converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration comprises removing the at least one clip to place the neck extension in the extended deployed configuration.

12 . The method of claim 1 further comprising the step of providing adhesive to retain the neck extension in a vicinity of the first interior compartment at a first side of the tissue containment bag and to serve as the retainer, wherein the adhesive comprises at least one adhesive strip.

13 . The method of claim 12 wherein the step of converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration comprises pulling the neck extension in a direction away from the first interior compartment at the first side of the tissue containment bag to release the adhesive from the neck extension.

14 . The method of claim 1 further comprising the step of providing a channel connected to the sidewall along the neck extension; the channel being 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.

15 . The method of claim 14 further comprising the step of transferring insufflation fluid into the channel to unfurl, untwist or unflip the neck extension in the extended deployed configuration within the body cavity.

16 . The method of claim 15 wherein the insufflation fluid is transferred via a connector connected to a source of insufflation at a proximal end of the channel resident outside the body cavity.

17 . The method of claim 1 further comprising the steps of:

providing a tether connected to the sidewall along at least a top portion of the neck extension and extending freely beyond the distal end of the neck extension; and

pulling the tether within the body cavity to unfurl, untwist or unflip the neck extension in the extended deployed configuration.

18 . A method comprising the steps of:

providing a tissue containment bag for deployment and removal of a tissue specimen inside a body cavity; the tissue containment bag having 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 neck extension extending laterally outwardly from the first interior compartment when in an extended deployed configuration;

placing the tissue containment bag into a low-profile delivery configuration for facilitating percutaneous insertion; and

converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration,

wherein the step of placing the tissue containment bag into a low-profile delivery configuration comprises inverting the neck extension from its distal end into the second interior compartment and further along the second interior compartment passing an entryway intersection at the proximal end of the neck extension between the first interior compartment and the second interior compartment and into the first interior compartment.

19 . The method of claim 18 further comprising the step of providing a tether connected to the sidewall along at least a portion of the neck extension and extending freely beyond the distal end of the neck extension.

20 . The method of claim 19 wherein the step of converting the tissue containment bag from the low-profile delivery configuration into a deployed configuration comprises pulling the tether outwardly to extend the neck extension from the low-profile delivery configuration to the extended deployed configuration.
