Embodiment Construction

[0023] The present invention includes a balloon assembly such as figure 1 As shown, including balloon 1, the volume is 250-700cm 3 '; made of biomedical-grade silicon material; inflation catheter 2, molded together with the balloon as a whole, with a length of about 100cm and a diameter of 1.5-2.0mm, set on the ball pole 1 of the balloon, allowing Fluid or air is introduced to inflate the balloon 1 .

[0024] In a preferred embodiment, as figure 2 As shown, the inflation catheter 2 presents a puller guide 3 that becomes an extension of the end of the balloon 1 for pulling the balloon into the gastric space and guiding the catheter 2 through the stomach wall and other abdominal tissues. The pulling guide device 3 is made of high resistance silicon material or polypropylene material.

[0025] The invented assembly also includes a support piece 4, which is usually a flat plate, preferably made of medical grade material like silicon material, with an optimum thickness of 1.5-2...

Abstract

The invention relates to an intragastric balloon for the treatment of persons having severe or morbid obesity problems, which reduces the number of elements in known systems and makes possible a saving in material in its manufacture. The intragastric balloon assembly comprises a balloon connected to a catheter in order to inflate it and includes a means for attaching it to the patient's body comprising a flat fixing plate with a single orifice through which the inflation catheter is passed, which plate is fixed subcutaneously in the patient's abdominal region and in a preferred embodiment an additional supporting member is provided through which the inflation catheter is firmly supported on the fixing plate and comprises a semi-rigid silicone washer or ring which is secured to the catheter and the supporting plate with appropriate adhesive, holding the catheter in place with adequate tension for the balloon to lie against the stomach wall perfectly but without any pressure. In addition to this the assembly comprises a multiple-puncture valve to which the inflation catheter is connected to inflate the balloon, which may in turn be located on the fixing plate, thus providing an alternate element for supporting the catheter and therefore the balloon assembly.

Description

technical field [0001] The present invention relates to the fields of gastroenterology and general surgery, in particular the treatment of populations with severe obesity or morbid obesity. Background technique [0002] For two decades, a number of internal and external gastric devices have been used to help those who are severely obese or morbidly obese lose weight. Currently, most forms of devices used are bands, balloons, or modifications to increase their effectiveness and avoid complications. But problems like gastric leaks and infections, necrosis of the stomach wall in contact with the device, etc., which are typical for patients in general, and the results of multiple weight loss failures and failures have not been resolved. Likewise, the surgical techniques used to treat severe obesity are complex and lead to increased pathological mortality, not to mention increased treatment costs. [0003] For examples of related devices, see US Patent Application No. US2003 / 01...
