Description

Disposable balloon catheter system

Technical Field

The invention relates to the technical field of medical instruments, in particular to a disposable balloon catheter system.

Background

The length between the stomach and the jejunum is equivalent to the length of the side-by-side twelve transverse fingers, and the total length is about 25 cm. The duodenum is the shortest, largest, deepest and most stationary portion of the small intestine. The initial and final ends of the duodenum are wrapped by the peritoneum, and most of the duodenum is an extraperitoneal organ, which is covered by the peritoneum and fixed on the back wall of the abdomen. Because it receives both gastric juice and pancreatic juice and bile, the digestive function of the duodenum is important. The duodenum is overall in a 'C' shape, surrounds the pancreas and can be divided into an upper part, a descending part, a horizontal part and a ascending part, the transverse section of the duodenum of the observation specimen is used for observing the purple red color of the mucosa by naked eyes, and the transverse section of the duodenum is outwards provided with the submucosa, the muscular layer, the adventitial mucosa and the submucosa which are protruded inwards to the lumen to form annular plica.

Type two diabetes is a chronic condition that affects the body's metabolic sugar (glucose). In type ii diabetes, the body is either resistant to the effects of insulin, a hormone that regulates the movement of sugars into cells, or is unable to produce enough insulin to maintain normal blood glucose levels. Although more common in adults, type ii diabetes increasingly affects children as childhood obesity increases. For type ii diabetes, there is no known cure. In some cases, control can be exercised through good diet, exercise, and maintenance of healthy weight. If diet and exercise are not sufficient to control blood glucose levels well, diabetes medication or insulin therapy may be required.

A balloon catheter is understood to include a catheter and a balloon disposed on the catheter, whereby a medium may be introduced into the balloon through the catheter to inflate the balloon, and the inflated balloon may be used for dilatation or the like.

However, in the related art, the balloon catheter usually can only achieve expansion, and has a single function, which is difficult to satisfy the requirements of various medical and diagnostic activities, such as: minimally invasive endoscopic procedures, such as duodenal mucosal resurfacing, are aimed at removing the surface epithelium to allow subsequent epithelial regeneration and replacement to a more insulin sensitive state. This process replicates aspects of bariatric surgery and provides an attractive alternative to the treatment of metabolic disorders where ablation is required in addition to dilatation, which is difficult to meet with existing balloon catheters.
