1. A device for sealing an incision through a layer of body tissue into an insufflated body cavity, the device comprising:
- a tube having a distal portion and a proximal portion defining a bore therebetween, wherein the distal portion of the tube is cylindrical and the proximal portion of the tube is conical;
a cylindrical balloon membrane having a distal end and a proximal end disposed in the bore, the cylindrical balloon membrane having an inner balloon tube and an outer balloon tube, the inner balloon tube and outer balloon tube being sealed together at the distal and proximal ends of the balloon membrane to form a closed surface that can be inflated; and
an inflation port, the inflation port adapted to be in fluid communication with the balloon membrane and the insufflated body cavity thereby permitting insufflation fluid to enter the balloon membrane.

Abstract
A skin seal or trocar stabilizer with an inflatable balloon in the shape of a dumbbell, where the balloon may be stored within a cannula for easy placement in an incision and inflated to deploy the balloon inside the body, and a portion of the balloon expands inside the cannula, whereby medical instruments may be passed through the skin seal into a laparoscopic workspace while the balloon is inflated, thereby allowing the use of normal short surgical instruments during laparoscopic procedures and during insufflation.

5. A device for sealing an incision through a layer of body tissue into an insufflated body cavity, the device comprising:
-
a rigid tube having a distal portion and a proximal portion defining a bore therebetween;
a cylindrical balloon membrane having a distal end and a proximal end disposed in the bore, the cylindrical balloon membrane having an inner balloon tube and an outer balloon tube, the inner balloon tube and outer balloon tube being sealed together at the distal and proximal ends of the balloon membrane to form a closed surface that can be inflated; and
an inflation port, the inflation port adapted to be in fluid communication with the balloon membrane and the insufflated body cavity thereby permitting insufflation fluid to enter the balloon membrane;
wherein when the cylindrical balloon member is inflated, the outer balloon tube is adapted to seal around an incision through a layer of body tissue. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
