Bioengineering – Gastric Balloon Development

The paper “Bioengineering – Gastric Balloon Development” is a good example of coursework on technology. The gastric balloon, also known as the intragastric balloon is soft, elastic and a silicone balloon available for the purpose of weight loss. The device is placed inside the stomach of the obese person through a camera that penetrates into the stomach via the mouth. Once the balloon is positioned in the stomach, it is filled with sterilized saline whose main function is to occupy the balloon and cause a feeling of fullness within the stomach.

The obese person is thus able to reduce the quantities of food they take and hence help in reducing the body size (William 2008 pp. 27). The process is very simple and less disturbing as the placement of the balloon takes around 20 minutes and should be done by qualified gastroenterologists. The process does not involve any surgery. The balloons should be tested for quality and should be designed by highly qualified bio-engineers. The balloon is reversible and helps in reducing hunger temporarily, controlling the intake of food, initiating some changes in behavior, and help in achieving an overall weight loss of 10 to 30kgs.

The balloon is uninflated, ingestible, and substantially liquid-impermeable with both an exterior and interior surface bounding the lumen. The balloon also encloses an emissive substance that liberates gas to inflate it upon contact with reactants (Sreenivasa 2015 pp. 86). There is also a vessel within that comprises a receptacle fabricated of the gelatin and having a mouth. The receptacle is attached at the mouth to a septum (self-sealing valve) by a liquid-impermeable seal. This paper discusses the structure, the development, and the design process of the most current and updated gastric balloon.

I this paper, the use and application of the balloon are discussed as well as how the balloon design and features can be improved for future use. The origin of gastric balloons can be traced back in 1982 and was proposed as a way of controlling obesity by Nieben bringing in the use of the first artificial space-occupying intragastric balloon for losing weight. It is often considered as a non-surgical restrictive procedure for losing weight as it theoretically affects both gastric capacity and stretch receptors thereby increasing satiety while decreasing the available residual volume for food (William 2008 pp.

38). The intragastric balloon is a saline-filled balloon that can hold a maximum volume of 700mL. It is technically inserted into the patient’ s stomach in a similar way as other balloons such as BIB and Silimed. However, it is a bit more peculiar as the manufacturer is recommended to treat the outer surface of the balloon with a lubricant before it is implanted and also introduce the lubricant under the sheath so as to provide easy detachment of the balloon from the filling tube.

After it is implanted, patients take antiemetics like metoclopramide and thiethylperazine for a few days at home. It is an effective method of slashing off weight temporarily with low mortality and morbidity. Its design comes from the design of the commonly approved Bioenterics Intragastric Balloon (BIB) (Sreenivasa 2015 pp. 106).
