Summary of Biliary Drainage Catheter Models and Specifications

Model Identification

The document lists several models of biliary drainage catheters, identified by codes such as AMH-NC-7F-A, AMH-NC-7F-B, AMH-NC-8.5F-B, AMH-NC-7F-D, and AMH-NC-8.5F-D.

Size and Dimensions

• Catheter sizes are specified as 7 French (F) and 8.5 French (F).
• Length or related dimension is consistently noted as 2700 (units not specified, likely millimeters or centimeters).
• Diameter or thickness is indicated as 0.035 (units not specified, likely inches or millimeters).

Design Features

• Some catheters have a 'Pigtail' shape, which is a coiled tip design used to secure the catheter in place.
• Variants include 'a shape' and 'a+Right Pigtail,' indicating different tip configurations for specific clinical applications.

Product Category

All models fall under the category of Biliary Drainage Catheters, which are medical devices used to drain bile from the biliary system.

Key Points and Recommendations

• Selection of catheter size (7F or 8.5F) should be based on clinical requirements.
• Tip design (Pigtail or other shapes) affects catheter stability and placement.
• Consistent length and diameter parameters suggest standardized manufacturing specifications.
