The radial compression fixture can be mounted to any Instron 5940 or 5960 series system and can utilize standard Bluehill® Universal software to control the test. For all fatigue tests, including testing the structure of the stent body or the entire stent in cyclic extension control, we recommend using our ElectroPuls™ test systems.
crushing test for stents instron mongolia Traditional testing of stent and stent grafts to standards such as ASTM F2477 involves subjecting complete devs to pressure pulsation simulating blood flow for a prespecified number of cycles Even if the dev has not fractured a simple passfail criterion is used for the test to succeed
Crushing Load Maximum compressive force applied during a compression or crushing test. For materials that do not shatter, crushing load is defined as the force required to
A typical test requires a pill to be either compressed to failure or compressed to a certain force and checked for puncture. Although the test itself is relatively straightforward, having the appropriately sized compression platen or probe is critical to ensure the pill does not slip out from under load, and that the force is properly
Traditional testing of stent and stent grafts (to standards such as ASTM F2477) involves subjecting complete devs to pressure pulsation simulating blood flow for a pre-specified number of cycles. Even if the dev has not fractured, a simple pass/fail criterion is used for the test to succeed.
Fatigue Testing of Stents and Stent Materials instron.ar Traditional fatigue testing of complete stent devs is addressed by ASTM F2477 “Standard Test Methods for in vitro Pulsatile Durability Testing of Vascular Stents”, which specifies methods for fatigue of complete devs through hydrodynamic pulsation.
Dec 30, 2013· To enable a representative sample of specimens to be evaluated and to reduce overall test time, multiple samples must be tested. The multi-specimen fixtures assist cardiovascular implant manufacturers to assess these long-term fatigue characteristics of nickel-titanium (Nitinol), CoCr, stainless-steel, and other stent materials and structures.
ASTM F2606-08(2014) "Standard Guide for Three-Point Bending of Balloon Expandable Vascular Stents and Stent Systems" provides guidelines for quantitatively characterizing these products. It provides data that can be used to compare the flexibility of different products by direct comparison of load-deflection curves and by comparison of
Instron partners with Machine Solutions Inc. (MSI) to utilize either a RX575 or RX675 stent iris on an Instron system. The fixture can also be customized and used for special specimen types to provide radial strength and stiffness over the entire graft or the securing graft ends.
Preventative maintenance helps you get the most out of your test system, and combining preventative maintenance with calibration servs is the most convenient and economical way for you to meet ISO 9001, ASTM E4, and ASTM E83 compliance requirements.. Instron's engineers have access to the documentation, factory-specified parts, and tools required to maintain your equipment at its peak

Aug 31, 2020· Pete Bailey, Instron (Image courtesy of Instron) There are many quality controls applied to the design and release of coronary and other vascular stent devs, but a proof test of pulsatile durability, such as those laid out in ASTM F2477-19 (i.e. fatigue in diametral distension), is probably one of the most unavoidably time-consuming.
