Stent

Abstract

Disclosed herein is a stent implanted in the body of a patient. The stent includes a hollow cylindrical stent body which is made of a super-elastic shape memory alloy and has an expanded diameter part on one end thereof, and a support stent which has an elastic spherical structure and is fitted over the cylindrical stent body behind the expanded diameter part. The stent is implanted in the body such that food that has passed through the stomach is prevented from mixing with bile or pancreatic juice in the duodenum and moves directly into the small intestine to prevent the duodenum from absorbing nutrients of the food while the small intestine directly digests the food and absorbs the nutrients, thus minimizing a nutrient absorption rate, thereby preventing the obesity of the patient.

Description

field of invention [0001] The present invention relates generally to a stent to be implanted in the stomach of a patient undergoing gastrectomy so that when the patient ingests food, the stent prevents inflammation on the sutured area of ​​the stomach that will come into contact with the food and prevents Reopening of the stitched area due to inflammation or compromised ligation of the stitched area thereby reducing the time required to heal the stitched area, and more particularly, the present invention relates to a stent configured so as to prevent passage of food through the stomach Mixes with bile or pancreatic juice in the duodenum, and makes the food go directly to the small intestine, preventing the duodenum from absorbing the nutrients of the food, while the small intestine directly digests the food and absorbs the nutrients, thus minimizing the rate of nutrient absorption, thereby prevent obesity in patients. technical background [0002] Usually, BMI (body mass in...

Problems solved by technology

[0010] However, after gastrectomy, the patient must seek medical attention or receive outpatient treatment, and there is a possibility of vomiting, diarrhea, abdominal hernia, infection, pneumonia, respiratory disease, etc.

Also, if the commissure between the stomach and intestines is defective, digestive juices can leak from the stomach

[0011] Additionally, such problems increase medical costs, as additional costs from complications can outweigh the cost of surgery and continuing treatment

[0012] In addition, when food is ingested by patients undergoing gastrectomy, the food comes into contact with the stitched area, causing pain
