Radial support force tester for vascular stent

CSI-Z506 radial support force detector (bath constant temperature type), (nickel titanium shape memory alloy self expanding type)Radial support force tester for vascular stent

‌Radial support force tester for vascular stent

1、 Instrument Introduction:

The water bath type radial support force tester can keep the waterproof pressure grip head in a water bath at 37 ℃ (or other required temperature) for a long time, meeting the requirements for constant temperature radial force testing of temperature sensitive metals or other materials, especially for radial force testing of stent medical device products such as nickel titanium alloy and shape memory alloy.

2、 Key parameters‌

3、 Execution standards and applicable scenarios‌

Compliant with standards:

T/CSBM 0018-2021 "Test Method for Shape Recovery Ability of Nickel Titanium Shape Memory Alloy Self Expanding Vascular Stent"

YY/T1660-2019 "Radial Load Test Method for Balloon Dilation and Self Dilation Vascular Stents"

Typical applications:

Batch quality inspection of production line;

Third party laboratory certification.

4、 Example of Operation Process‌

1) If the vascular stent has been loaded, immerse the vascular stent system in a constant temperature water bath at 37C ± 2C for no less than 2 minutes, and release the vascular stent from the sheath in the constant temperature water bath; If the bracket is not loaded, this operation is not required.

2) For self expanding variable diameter vascular stents, it is necessary to evaluate the radial support force of different segments.

3) The temperature of the testing device is maintained at 37C ± 2C; the initial aperture is larger than the natural diameter of the testing bracket.

4）Place the released vascular stent in the testing hole of the device at a constant temperature for at least 2 minutes.

5) According to the status of the vascular stent, slowly reduce the aperture of the testing device as much as possible to the preloaded diameter of the vascular stent or reduce the diameter by at least 50%, and then slowly increase it to the unloaded state (recommended moving speed: 0.1mm/s~0.5mm/s).

6) Measure the force value of expansion or compression corresponding to the expected size of the implanted blood vessel diameter during the testing process, and observe whether the vascular stent can restore its initial shape after the external force is removed.
