摘要： Balloon compositions that may be used for deployment of implants within a patient's body. The balloons in examples may be utilized for dilating implants and may be coupled to a delivery catheter for an implant. In examples, the balloons may be utilized to dilate other surfaces within the patient's body.

摘要： A drug-loaded medical device, a preparation method therefor, a drug balloon and a method of preparing a drug coating are disclosed. The medical device or the drug balloon is provided on a surface thereof with a drug coating including a stabilizer and a drug. The stabilizer includes an amphiphilic triblock polymer with hydrophilic segments at both terminals, and the drug coating forms a nano-drug particle suspension in a water-soluble environment. In this way, the prepared nano-drug coating has high drug loading and can deliver the drug in a desirable way. In particular, when it comes into contact with water, the drug can be restored to the original nano size, almost without any particle size increase. This not only avoids the risk of embolism caused by granules, but also enables higher device safety, increased drug uptake and improved therapeutic effects.

摘要： A multi lumen gastrointestinal catheter is disclosed. The multi-lumen gastrointestinal catheter has a flexible partition separating a feeding and an aspiration channel. A third smaller inflation channel is positioned within the outside exterior wall at the site of the flexible partition to avoid kinking at the inflation channel site, without need to re-enforce the weakened wall.
