Abstract

A method and article for medical diagnosis and/or treatment of body disorders, comprising a sleeve unit insertable in a natural body vessel to isolate material flowing into the vessel from direct contact with the interior surface of the vessel. When applied to the treatment of obesity, the sleeve is disposed along a zone in the digestive tract to interfere with the digestive or absorptive function of that zone and thereby reduce net caloric intake.

Claims

1. A method of treating an area of a body vessel, comprising the steps of:

introducing a catheter with a collapsed inflatable annular balloon and a collapsed sleeve encircling the balloon on its end into the vessel at a point remote from the area to be treated;

manipulating the catheter axially along the vessel to cause the balloon and sleeve to enter the area to be treated;

inflating the balloon by introducing fluid under pressure into the balloon through a tube of the catheter in a manner wherein the sleeve surrounding the balloon is radially expanded towards the wall of the vessel;

providing in the sleeve a material which increases in rigidity after expansion of said balloon;

maintaining said balloon in an expanded condition in the vessel while said sleeve increases in rigidity and body fluid is allowed to pass through the central aperture of the balloon; and

thereafter removing the balloon and catheter from the vessel and allowing the sleeve to remain in place in the area to be treated.

2. A method of treating an area of a body vessel, comprising the steps of:

introducing a catheter with a collapsed inflatable balloon and a collapsed sleeve encircling the balloon on its end into the vessel at a point remote from the area to be treated;

manipulating the catheter axially along the vessel to cause the balloon and sleeve to enter the area to be treated;

inflating the balloon by introducing fluid under pressure into the balloon through a tube of the catheter in a manner wherein the sleeve surrounding the balloon is radially expanded towards the wall of the vessel;

providing in the sleeve a material which increases in rigidity after expansion of said balloon;

maintaining said balloon in an expanded condition in the vessel while said sleeve increases in rigidity; and

thereafter removing the balloon and catheter from the vessel and allowing the sleeve to remain in place in the area to be treated.
