Generally speaking, belonging to the implantable devices, interventional devices, medical suture materials and adhesives and other major categories of products are clearly defined, and in the major categories are involved in the small categories of device products. Reference and comparison can be concluded.
Based on your question, drainage catheter belongs to 6866 Medical Polymer Materials and Products, which belongs to Class I and Class II medical device products according to the catalog. Like thoracic drainage tube, abdominal drainage tube, cerebral fluid shunt tube, urinary catheter, bile duct drainage tube, disposable use of protein adhesive lumens with the tube, balloon catheter automatic retractor, cerebral suction tube belongs to the second class of medical devices; there are also like pharyngeal tube catheter, thoracic drainage regulator belongs to the first class of products.
In addition, the classification of medical devices belonging to the interventional device products to provide you with reference:
6877 interventional products: intravascular contrast catheters, balloon dilatation catheters, central venous catheters, trocars peripheral catheters, micro-floating catheters, arterial and venous manometry catheters.
