An improved wire guide and method for cannulating a bodily lumen, such the biliary tree are provided for procedures such as endoscopic retrograde cholangiopancreatography (ECRP). The wire guide and cannulation method minimizes the potential for trauma to the ducts while reducing the chances of disconnecting the wire guide from newer access devices. Generally, the wire guide includes an atraumatic tassel tip which is operable between delivery and deployed configurations.

A method is disclosed for distending a body lumen in the performance of endoscopic retrograde cholangiopancreatography (ERCP). The method comprises insufflating the body lumen with contrast agent to distend the body lumen. The contrast agent includes gas.

A catheter for inserting into a bodily structure. The catheter includes a primary lumen and a secondary lumen having a side hole for engaging under negative pressure with an inter-mural mucosa of the bodily structure. Methods of use of a catheter involving insertion of the catheter into a bodily structure and engaging the catheter under negative pressure with an inter-mural mucosa of the bodily structure.

The invention discloses an integrated multifunctional double-balloon catheter, and relates to the technical field of medical instruments. The integrated multifunctional double-balloon catheter comprises a catheter body, a guide wire cavity is formed in the catheter body, a contrast agent outlet is formed in the end, close to the guide wire cavity, of the catheter body, the outer side of the catheter body is sleeved with a first radiopaque ring, a calculus removing balloon is installed on the catheter body, and an air bag air outlet is formed in the calculus removing balloon. The air bag air outlet is connected with the catheter body, and a dilation balloon is installed on the catheter body. According to the integrated multifunctional double-balloon catheter, the length of the narrow section of the digestive tract can be accurately measured during digestive tract dilation, the dilation effect can be evaluated through the calculus removing balloon at the front end, and the calculus removing balloon and the dilation balloon are arranged on the catheter body, the integrated multifunctional double-balloon catheter can be used for realizing conventional expansion and calculus removal operations in endoscopic retrograde cholangiopancreatography (ERCP), the manufacturing cost is lower than that of two instruments, and the cost performance is high.

The invention discloses a needle-shaped minimally invasive interventional duct-inserting device for cholangiopancreatography and belongs to the technical field of medical instruments. The needle-shaped minimally invasive interventional duct-inserting device mainly comprises a novel needle-shaped knife main body, a guide wire propelling unit and a foot-controlled washing unit. The novel needle-shaped knife main body comprises a propelling rod, a handle, an electrode plug and a multi-cavity duct. The multi-cavity duct comprises a guide wire cavity inlet, a washing liquid cavity inlet, a radiography liquid cavity inlet, a guide wire cavity, a knife wire cavity, a radiography liquid cavity and a washing liquid cavity. Guide wires penetrate into the guide wire cavity, knife wires are arranged in the knife wire cavity, and a knife wire clamping head is arranged at the remote end of the knife wire cavity; and the guide wire propelling unit is arranged on the outer guide wires in a penetrating and sleeved mode, and the foot-controlled washing unit is connected with the washing liquid cavity inlet. In short, the needle-shaped minimally invasive interventional duct-inserting device for cholangiopancreatography is simple in structure, convenient to use, high in duct-inserting success rate, small in damage and low in complication occurrence rate.

The invention provides a contrast agent for magnetic resonance cholangiopancreatography use, which is tea water, the manganese concentration of which ranges from 5mg / l to 13mg / l. In the invention, thetea water used as the contrast agent has good taste, stable structure in human body, no changes to gastrointestinal system functions, high security factor, nontoxicity, good relaxation, no fermentation in intestinal cavum and no gas generation, and the intestinal cavum is fully filled with the tea water to ensure uniform signals in the intestinal cavum. The tea water has high solubility, low cost, wide sources, easy acceptability for sufferers, low concentration for orally taking without any obvious discomfort, nausea, vomiting and constipation, and the application of the contrast agent is realized by requiring no drug test; disease diagnosis can be realized by drinking the tea water, which is more acceptable for patients compared with chemical medicines. Furthermore, the application of the contrast agent is realized by requiring no drug test, thus greatly reducing the diagnosis charges of the patients.

Disclosed are a device and method for fixing and shortening the bowel at the time of endoscopy. The device and method can improve the shortening efficiency of the bowel when compared with the existing endoscope surgery, reduce the inspection time, and mitigate patient inconvenience. Furthermore, an endoscope machine that has been used by an operator can be used, thereby facilitating an operation, and the machine itself need not be separately purchased, thereby obtaining a cost reduction effect. Furthermore, through the application of principles of the device and method, a colonoscopy which is difficult due to the formation of a loop, or retrograde cholangiopancreatography inspection and treatment of a patient having an abnormal anatomical structure due to an operation can be further anticipated.
