摘要： If smooth transportation of bile toward the duodenum is difficult due to cancerous cells growing in the bile duct or due to stricture of the bile duct, a cylindrical stent may be implanted into the stenosed site of the bile duct to enable smooth supply of bile. Conventional stents have no risk of slippage at an implanted position thereof, but suffer from invasively growing cancerous cells. Although a covered stent having a coating has been proposed to solve invasion of the growing cancerous cells, the covered stent may have a risk of slippage at an implanted position thereof and also, may cause pancreatitis and cholelithiasis. To solve the above described problems, disclosed herein is a stent to prevent backflow of food from the duodenum to the bile duct while assuring smooth transportation of bile without a risk of unwanted displacement caused by the transported bile. The stent includes a cylindrical outer stent, and a downwardly tapered inner stent covered with a polytetrafluoroethylene (PTFE) or silicone coating having biocompatibility. The inner and outer stents are coupled to each other to define a double structure.
摘要翻译：如果胆汁向十二指肠顺利运输是困难的，因为胆管内生长的癌细胞或胆管狭窄，可以将圆柱形支架植入胆管狭窄部位，以使胆汁平稳供应。常规的支架在其植入位置没有滑动的风险，但遭受侵袭性生长的癌细胞。虽然已经提出了具有涂层的覆盖支架来解决生长中的癌细胞的侵袭，但是所覆盖的支架可能在其植入位置处具有滑动的风险，并且还可能引起胰腺炎和胆石病。为了解决上述问题，本文公开了一种用于防止食物从十二指肠向胆管回流的支架，同时确保胆汁的平稳运输，而不会由于运输的胆汁引起不希望的位移。支架包括圆柱形外支架和用聚四氟乙烯（PTFE）或具有生物相容性的硅氧烷涂层覆盖的向下锥形内支架。内支架和外支架彼此连接以限定双重结构。

摘要： A wavily deformable stent includes a hollow cylindrical net body formed of elastically deformable wires interlaced with each other. The net body extends in a longitudinal direction and terminates at open opposite ends. The net body has at least one high-rigidity section and at least one low-rigidity section less rigid than the high-rigidity section. The high-rigidity section and the low-rigidity section are arranged continuously and alternately along the longitudinal direction. The stent is wavily deformed and held in place against unwanted displacement when situated inside a stenosed part of a bodily organ. Also provided is a method for producing the wavily deformable stent.

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 biodegradable double stent is used for various organs such as a biliary tract, an esophagus, an airway and a ureter. A biodegradable stent having a hollow cylindrical body woven out of a separate wire made of biodegradable polymer so as to have a plurality of rhombic spaces is fixed to an intermediate portion of a primary stent having a cylindrical body. When administered into the organ, the biodegradable stent has its original function of expanding the organ, and is firmly supported in the inner wall of a narrowed passage of the organ by pressurizing the inner wall of the narrowed passage of the organ. After a predetermined time period has elapsed, the biodegradable stent is gradually degraded away by bodily fluids, thereby enabling the primary stent to be easily removed from the organ.

摘要： Disclosed herein is the resonant inverter of a radio frequency (RF) generator for radiofrequency ablation (RFA). The resonant inverter of RF generator for RFA amplifies to high power an oscillation frequency output from an oscillator and provides the amplified oscillation frequency to an electrode. The resonant inverter processes the oscillation frequency output from the oscillator as a high-power sine wave having a frequency of 480 kHz and a Root Mean Square (RMS) power of 30 to 200 watts, and transfers the high-power sine wave to the electrode.

摘要： An anti-migration stent includes a hollow stent body formed by interweaving a superelastic shape memory alloy wire diagonally such that upper and lower wires alternately cross over and under each other, forming multiple diamond-shaped spaces. After placing and holding a rod underneath the wire of the hollow stent body, and heating the stent body, an anti-migration bent part is formed on the wire, protruding vertically to form an outline corresponding to a cross-sectional shape of the rod, which makes stent production easy. The stent is prevented from migrating in a lumen of a human body by the bent part protruding vertically and diagonally from the stent body, and easy to insert into and remove from the lumen, preventing the conventional problem damaging an inner surface of the lumen.
