    摘要: Disclosed herein is a stent for connecting adjacent tissues of the organs of a patient. The stent includes a hollow cylindrical body which is formed by weaving a superelastic shape-memory alloy wire in an overlapping manner such that rhombic openings are formed, and wing parts which are provided by expanding respective opposite ends of the hollow cylindrical body outwards and turning the opposite ends inside out on bent portions. The wing parts face each other so that the wing parts are tensed in a longitudinal direction of the cylindrical body. Thereby, the wing parts can elastically move inwards or outwards with respect to the longitudinal direction to automatically adjust a distance between the wing parts in response to the distance between the adjacent tissues of the organs or thicknesses of walls of the organs, so that the wing parts are put into close contact with the adjacent tissues.

    摘要: A balloon type stent system for treatment of obesity is disclosed. An injection expansion unit and a plurality of distribution expansion units extend in a longitudinal direction of a stent unit body formed by coupling two sheets of synthetic vinyl in the shape of a cylinder. The injection expansion unit has an expansion agent injection port, and the distribution expansion units each have a distribution injection port communicating with a distribution channel. Connection ends are partially cut in the longitudinal direction such that the expansion units are divided into an integrated expansion unit and a separated expansion unit. The injection expansion unit and the distribution expansion units constituting the separated expansion unit are bent outward to form a balloon type stent unit. A tube has a length corresponding to a lumen length of the duodenum, and the tube is connected to the stent unit body by a connection wire.

    摘要: A double-tube type stent is inserted into a hollow tubular organ such as a bile duct so as to relieve narrowing of the bile duct on, for instance, an anastomotic area of the intrahepatic bile duct of a liver transplant patient. A hollow cylindrical body has a plurality of rhombic spaces formed by weaving a superelastic shape-memory-alloy wire so as to be crossed. A silicon coating layer is coated on an outer surface of the cylindrical body using a silicon solution. A polytetrafluoroethylene (PTFE) tube is fixedly fitted around the cylindrical body having the silicon coating layer leaving a gap therebetween.

    摘要: A stent inserting device is used in inserting a self-expandable stent with leading and trailing ends into a tubular organ of a living body. The stent inserting device includes a grip body, an external tube attached to a front end of the grip body, a push member movably inserted into the external tube from a rear end of the grip body, and a tubular cap for removably receiving the stent in a compressed state. The tubular cap has a front end operatively connected to the push member and a rear end slidably fitted to a front end of the external tube. The stent inserting device is designed to hold the stent within the tubular cap in such a manner that the stent is first expanded at the trailing end and then gradually expanded toward the leading end when the tubular cap is pushed away from the external tube.

    摘要: Disclosed herein is a drawstring for removal of a stent. The drawstring includes an end string, a longitudinal string and a circumferential string. The end string is formed in an end of the stent body in an annular shape in such a way that the end string passes, in a zigzag manner, through mesh arranged in a circumferential direction of the stent body. A hook loop is formed by tying opposite ends of the end string to each other. The longitudinal string extends at a first end thereof from the end string in the longitudinal direction of the stent body. The circumferential string extends from a second end of the longitudinal string and is formed in an annular shape in such a way that the circumferential string passes, in a zigzag manner, through mesh arranged in the circumferential direction of the stent body.

    摘要: Disclosed is an esophageal stent placed in a stenosed part of the esophagus having a flexible tube to prevent the reverse flow of gastric contents from the stomach is coupled to the lower end of the esophageal stent. The flexible tube has an inside membrane and an outside membrane adhered to each other, thus having a twofold structure with at least one core longitudinally placed between the adhered inside and outside membranes while the core extends from the upper end toward the lower end of the flexible tube. Thus, the flexible tube is prevented from being inverted, and prevents the reverse flow of the gastric contents, and maximizes the operational reliability of the esophageal stent. The flexible tube does not cause a patient pain or discomfort due to frictional contact of the tube with the inner surface of the stomach when the tube moves in the stomach.

    摘要: Disclosed herein is a method and system for controlling radio frequency (RF) output according to the change in impedance of biological cells. In the method of controlling radio frequency (RF) output according to a change in impedance of biological cells, phases of RF voltage and current applied to the electrode are detected and a difference between the phases is obtained. A change in impedance such as a resistance component and a capacitive reactance component (XC) of the biological cells at the time of performing cauterization is obtained. An inductive reactance component (XL) is connected to an RF output terminal so as to cancel the capacitive reactance component (XC) (XC=XL), thus enabling the output impedance to have a resistance component.
