Abstract

Apparatus for inserting and inflating a balloon in a patient's stomach in the treatment of obesity comprises means for introducing the balloon inflating it after introduction and removing the introducer. Suitably the balloon is carried within a wrapper at the end of introducer means in the form of a rod surrounded by a tube. After positioning of the balloon, the rod is withdrawn and the balloon inflated, bursting the wrapper, by gas or by gas-forming chemicals supplied through the tube and a non-return valve, after which the tube is withdrawn with the split wrapper.

Description

SPECIFICATION Balloon introducer apparatus The invention relates to apparatus for inserting and inflating a balloon in a patient's stomach in the treatment of obesity.

In accordance with the invention there is provided balloon introducer apparatus comprising a balloon carried at the distal end of elongate introducer means arranged to permit introduction of the bal loon into the stomach in a deflated condition and balloon inflation in the required location, the balloon being associated with the introducer means so as to permit withdrawal thereof from the inflated balloon without substantial loss of inflation.

The apparatus can thus comprise a balloon having a non-return valve through which the balloon can be inflated, an outer wrapping for the balloon in a deflected condition from which the balloon can escape on inflation, and elongate introducer means by which the balloon within the wrapping can be placed at a desired location in the stomach and then inflated through the non-return valve, the wrapper being secured to the introducer means for withdrawal therewith after inflation of the balloon at the desired location.

The elongate introducer means must provide a degree of mechanical strength as well as a conduit for supplying fluid to the balloon interior to effect inflation, and can comprise a rod of appropriate rigidity to act as a pusher during introduction of the balloon and a tube within which the rod is received and by which air or other fluid can be supplied to the balloon to effect inflation. The rod can be withdrawn independently of the tube after placement of the balloon and priorto inflation, the wrapping being secured to the tube. The deflated balloon can be flattened so that it can be coiled round the tube or folded so as to occupy a limited volume within the wrapper, with the tube extending through the nonreturn valve into communication with the balloon interior.

For a better understanding of the invention reference may be made to the following illustrative description and the accompanying drawings, in which: Figure 1 is a sectional side view of the distal end of a balloon introducer apparatus embodying the invention, shown in its initial condition; Figure 2 is a cross-sectional view of the apparatus on the line Il-Il of Figure 1; and Figure 3 is a sectional side view of the apparatus of Figure 1 but with the balloon in the inflated condition.

The illustrated balloon-introducer apparatus 1 comprises four components shown in Figures 1 and 2 assembled together ready for use. These components comprise a rod 2 received within a tube 4 having at its distal end a balloon 5 in a deflated condition wrapped around it. Finally, an outer casing or wrapper 6 encloses the balloon and is sealed to the exterior of the tube 4.

The rod 2 is of any suitable material and length for giving an appropriate degree of structural rigidity to the apparatus for enabling the balloon 5 within the wrapper 6 to be inserted into the patient's stomach.

The tube 4 within which the rod 2 extends is suitably of flexible plastics material and has at its proximal end (not shown) means whereby its interior can be put in communication with a source of liquid or air or other gas under pressure. Towards its open distal end, the tube 4 is provided with one or more apertures 8 for communication with the interior of the balloon 5 through a one-way or non-return valve 9 incorporated into the balloon structure.

The balloon 5 is made of any suitable material, for example plastics sheet material, capable of retaining air or liquid for an appropriate length of time and can be inflated to a general cylindrical shape of suitable dimensions, for example, a length of 14 cm. and a diameter of 9 cm. The non-return valve 9 is preferably of the lay-flat variety and is formed so as to extend either along the cylindrical side wall of the balloon from its proximal end to a position short of the distal end, or is free-lying in an exactly similar manner. During assembly of the balloon 5 with the rod 2 and the tube 4, the distal ends of the rod and tube are inserted through the valve 9 so as to extend beyond it into the balloon interior.The deflated balloon 5 is flattened orfolded so as to extend on either side of the tube 4 and is then furled tightly about the tube into the compact cylindrical configuration shown in Figures 1 and 2.

To facilitate introduction of the balloon 5 and to hold it in its coiled condition, the balloon is received within the outer wrapper 6 which has the form of a tube with one end closed. The balloon on the rod 2 and tube 4 is inserted through the open end of the wrapper 6, and this end is then sealingly secured to the tube as by a heat seal 10. The wrapper 6 is provided with at least one line 11 of perforations extending longitudinally and across the closed end, or is otherwise weakened along such a line or lines.

In use, the patient swallows the balloon 5 coiled within the wrapper 6 and the balloon is located where desired in the stomach by use of the rod 2 as a pusher. The rod 2 can then be withdrawn and air or other fluid under pressure is connected to the proximal end of the tube 4. The fluid leaves the end of the tube 4 to enter the balloon 5 inwardly of the non-return valve 9 and causes the balloon to distend.

The balloon expansion quickly splits the wrapper 6 along the perforated line 11 so that the balloon escapes and is free to expand to its predetermined maximum size as shown in Figure 3. The balloon 5 is thus lodged as required within the stomach and the tube 4 can then be withdrawn, carrying the split wrapper 6 along with it.

Inflation in situ of the balloon can instead be effected by means of a chemical reaction which generates an appropriate volume of gas. The reagents employed are conveniently both liquids, introduces successively through the tube 4 after the balloon has been positioned in the stomach. Thus a first liquid containing a carbonate can be introduced, followed by a weak acid. On reaching the balloon, the acid will react with the carbonate inside it to liberate carbon dioxide to effect inflation.

One or more of the components of the apparatus can be radio-opaque, at least in part, so that its position can be checked by X-ray examination.

Additionally or instead, where inflation is effected by chemical means, at least one of the reagents, for example, the carbonate mentioned above, can be chosen so as to be radio-opaque.

The invention can of course be embodied in other forms of apparatus than as specifically described.
