ISO 10555 Catheter Kink Resistance Testing
The ISO 10555 standard specifies the procedure for determining the kink resistance of medical devices, particularly catheters. This test evaluates how a catheter maintains its integrity under bending stress, ensuring it can navigate through tight anatomical structures without damaging or collapsing.
For medical device manufacturers, this test is crucial to meet regulatory requirements and ensure product safety and performance. The ISO 10555 test involves subjecting the catheter to a defined angle of bend and assessing its ability to resist kinking under specified loads. This ensures that the catheter maintains its functionality in real-world conditions.
The testing apparatus typically consists of a bending fixture capable of applying controlled force and angle, along with a load cell to measure the applied force accurately. The procedure involves inserting the catheter into the fixture, bending it to the required angle at specific points, and then applying incremental loads until kinking occurs or specified failure criteria are met.
The acceptance criteria for this test are based on visual inspection of the catheter's condition after testing. If no visible signs of kinking or damage occur within a predefined number of cycles or applied force, the device passes the test.
| Specimen Preparation | Testing Parameters | Acceptance Criteria |
|---|---|---|
| Catheter must be clean and free from defects before testing. | Bend angle: 180°; Applied force increments up to 2N (or as specified by the manufacturer). | No visible kinking or damage after applying the specified load or number of cycles. |
| Testing must be conducted at room temperature and controlled humidity levels. | Number of cycles: Minimum five cycles, unless otherwise specified in the standard. | Visual inspection of catheter for any signs of kinking, damage, or deformation. |
The ISO 10555 test is essential in ensuring that medical devices are safe and effective. By testing for kink resistance, manufacturers can identify potential design flaws early in the development process, reducing the risk of product failure during use. This test also helps meet regulatory requirements, such as those set by the FDA and similar bodies worldwide.

Why It Matters
The kink resistance test is a critical aspect of medical device quality assurance because it directly impacts patient safety and device performance. Invasive procedures often require catheters to navigate tight, tortuous pathways within the body. A catheter that fails to maintain its shape under these conditions can lead to complications such as blockages or injuries.
From a regulatory standpoint, compliance with ISO 10555 is mandatory for many medical devices sold in international markets. This test ensures that manufacturers meet stringent quality standards, thereby reducing the risk of recalls and product liability issues.
The results of this test also play a significant role in R&D efforts. By identifying design weaknesses early, engineers can iterate on their designs to improve performance and reliability. Additionally, the data obtained from these tests can inform marketing strategies by highlighting the robustness and safety features of medical devices.
Industry Applications
- Catheters for diagnostic procedures
- Catheters used in interventional cardiology
- Vascular catheters for hemodialysis and other treatments
- Intravenous catheters for administering medications or fluids
| Device Type | Description |
|---|---|
| Catheter for Coronary Angiography | Used to inject contrast media into the coronary arteries during angiography procedures. |
| Ventricular Catheter | Inserted into the heart ventricles to measure pressure and oxygen content in the blood. |
| Intraosseous Infusion Catheter | Used for administering medications or fluids directly into bone marrow during emergency situations. |
The ISO 10555 test is particularly important for these devices, as they must maintain their shape and integrity throughout the procedure. Failure to do so can result in complications such as blockages, infections, or even life-threatening situations.
