Abstract

An apparatus for retracting an organ inside the body to gain access to an adjacent tissue includes a main chamber which is positionable within the body and inflatable to an expanded condition to retract a body organ. The apparatus includes an inflatable additional chamber which when inflated maintains the main chamber in the expanded condition, and the organ in the retracted condition, notwithstanding release of the main chamber from the inflated condition.

Claims

1. An apparatus for retracting an organ inside the body to gain access to an adjacent tissue, the apparatus comprising:

a main chamber having a thin, flexible main envelope,

inflating means for selectively inflating the main chamber to an expanded condition while in place within the body, inflation of the main chamber retracting the organ to a retracted condition, and

inflatable maintaining means, operatively associated with the main chamber, for maintaining the main chamber in the expanded condition, and the organ in the retracted condition, notwithstanding release of the inflation of the main chamber following the inflation of the main chamber to the expanded condition, the release of the inflation of the main chamber rendering the main chamber incapable of maintaining the organ in the retracted condition, the maintaining means having an open structure for providing access therethrough to the tissue, wherein the maintaining means comprises;

one, and only one, additional chamber, and

means for inflating the additional chamber to an expanded state to maintain the organ in the retracted condition.

2. The apparatus of claim 1, wherein the additional chamber is attached to the outside of the main chamber.

3. The apparatus of claim 1, wherein:

an additional envelope and part of the main envelope enclose the additional chamber, the additional envelope covering the part of the main envelope, and

a part of the main envelope not covered by the additional envelope provides a piercable window.

4. An apparatus for retracting an organ inside the body to gain access to an adjacent tissue, the apparatus comprising:

a main chamber having a thin, flexible main envelope,

means for selectively inflating the main chamber to an expanded condition while in place within the body, inflation of the main chamber retracting the organ to a retracted condition, and

maintaining means, operatively associated with the main chamber, for maintaining the main chamber in the expanded condition, and the organ in the retracted condition, notwithstanding release of the inflation of the main chamber following the inflation of the main chamber to the expanded condition, the release of the inflation of the main chamber rendering the main chamber incapable of maintaining the organ in the retracted condition, the maintaining means having an open structure for providing access to the tissue, and including an additional chamber enclosed within the main chamber.

5. An apparatus for retracting an organ inside the body to gain access to an adjacent tissue, the apparatus comprising:

a main chamber having a thin, flexible main envelope,

means for selectively inflating the main chamber to an expanded condition while in place within the body, inflation of the main chamber retracting the organ to a retracted condition,

maintaining means, operatively associated with the main chamber, for maintaining the main chamber in the expanded condition, and the organ in the retracted condition, notwithstanding release of the inflation of the main chamber following the inflation of the main chamber to the expanded condition, the release of the inflation of the main chamber rendering the main chamber incapable of maintaining the organ in the retracted condition, the maintaining means having an open structure for providing access to the tissue, and

tab means inside the main chamber for providing a point inside the main chamber that can be gripped with a suitable gripping tool to change the position of the at least partly inflated apparatus.

6. The apparatus of claim 5, wherein the tab means is attached to the main envelope.

7. An apparatus for retracting an organ inside the body to gain access to an adjacent tissue, the apparatus comprising:

a main chamber having a thin, flexible main envelope,

inflating means for selectively inflating the main chamber to an expanded condition while in place within the body, inflation of the main chamber retracting the organ to a retracted condition, and

inflatable maintaining means, operatively associated with the main chamber, for maintaining the main chamber in the expanded condition, and the organ in the retracted condition, notwithstanding release of the inflation of the main chamber following the inflation of the main chamber to the expanded condition, the release of the inflation of the main chamber rendering the main chamber incapable of maintaining the organ in the retracted condition, the maintaining means having an open structure for providing access therethrough to the tissue; and

a suction skirt means for providing drainage of the part of the body in which the apparatus is deployed, the suction skirt means being attached to the part of the main envelope that is substantially lower-most when the apparatus is deployed in the body.

8. The apparatus of claim 7, wherein the suction skirt means comprises an elongate tubular structure including a side wall having plural holes formed therein, and two ends, at least one of the ends being adapted for connecting to a suction line.
