Abstract
Aspects of the present disclosure relate to apparatuses and methods for puncturing a tissue wall (e.g., a tissue wall of a cancerous cyst) and removing fluids from the tissue without outward spillage of contents in vivo. In illustrative embodiments, the invention comprises the use of an apparatus disclosed herein including the steps of fixing an outer housing of the apparatus to the tissue wall with an adhesive, puncturing the tissue wall from within the outer housing so that any spillage is contained while reinforcing fixation to the tissue wall with a reinforcing element such as a balloon. In this way, the apparatuses and methods disclosed herein allow for spillage free tissue puncture and fluid collection.
Claims14
An apparatus comprising:
- an outer housing comprising a proximal portion, a distal portion and a lumen;
- a tissue contacting element in operable contact with the distal portion of the outer housing and comprising a surface adapted to adhere to tissue forming a surface of a cyst or cyst-like structure;
- an elongate assembly disposed within the outer housing comprising:
- a proximal portion;
- a distal portion;
- an activatable tissue reinforcing element comprising an inflatable balloon;
- an adhesive applicator disposed on the device to apply an adhesive to the tissue contacting element;
- and further comprising a securing mechanism that operably connects the outer housing to the elongate assembly
- wherein the tissue contacting element and the activatable tissue reinforcing element are disposed;
- in an arrangement on the apparatus such that:
- the outer housing can be inserted in a patient in vivo so that the tissue contacting element is adhered to the outer surface tissue of the cyst or cyst-like structure;
- the distal portion of the elongate assembly can be advanced through a puncture in the wall of the cyst or cyst-like structure;
- the activatable tissue reinforcing element is disposed in the apparatus so as to such that the inflatable balloon when inflated provides a support for the tissue contacting element adhering to an outer surface of the cyst or cyst-like structure;
- and
- the apparatus can be disposed in vivo so that fluid can be removed from the cyst or cyst-like structure through the lumen, thereby inhibiting leakage of fluid from the cyst or cyst-like structure in vivo.
An apparatus for puncturing a tissue wall, the apparatus comprising:
- an outer housing comprising a lumen having a proximal portion and a distal portion;
- an elongate assembly having a proximal portion, a distal portion, and an activatable tissue
- reinforcing element, wherein the activatable tissue reinforcing element comprises an inflatable balloon;
- an adhesive applicator disposed on the device to apply an adhesive to the tissue contacting element;
- and
- further comprising a securing mechanism disposed in the apparatus so as to fix the outer housing and the elongate assembly in relation to each other;
- wherein the elements are disposed in a three-dimensional arrangement on the apparatus such that:
- the outer housing can be advanced through a proximal space;
- the distal end of the outer housing can be fixed to a tissue wall;
- the elongate assembly can be advanced through the lumen and is distal portion into a distal space through a puncture in the tissue wall;
- and
- the activatable tissue reinforcing element can be activated within the distal space such that the fixation of the outer housing to the tissue wall is reinforced by the inflatable balloon when the inflatable balloon is inflated.
