“…The first results of the impact of the crimping procedure and storage on the mechanical properties of the PLLA/SIR spray-coated self-expanding nitinol stents show a slightly increase in radial force and bending stiffness due to the coating , as has been previously described in [4]. Crimping and further storage of the crimped stents leads to non considerable differences in radial force and bending stiffness.…”

“…The target coating mass was 3658 µg in order to establish a SIR loading of 1.4 µg/mm². The manufactured drug-eluting stents (DES) were tempered at 80 °C for 13 h. The mechanical behaviour was determined by measuring the radial force [2,3] and bending stiffness [3,4] before and after crimping the DES on a modified catheter system as well as after storage of crimped DES over a period of 2, 5 and 8 weeks.

“…For investigation of the influence of the guide wire on the trackability properties a special measurement arrangement was used [4]. The measurement arrangement consisted of a 5 F guiding catheter (Cordis VISTA BRITE TIP ® ), an in vitro vessel model (PMMA, ID = 2.5 mm), the guide wire to be tested and a stent system, all immersed in 37 °C water (image 1).…”

The trackability is an essential property for determining the handling characteristics of coronary stent systems. It depends on the friction properties and flexibility of the stent system, the constitution of the vessel, but also on the properties of the guide wire used for the intervention. The influence of five commercially available coronary workhorse guide wires of different manufactures (Abbott, BIO-TRONIK, Boston Scientific, Medtronic, Terumo) on trackability of two different stent systems was tested. Proximal shaft force was measured while moving a stent system over the guide wire to be tested into an in vitro vessel model. The trackability of the stent systems was best with BIOTRONIK Galeo Hydro and worst with Boston Scientific Luge™. The trackability of stent systems does not only depend on the properties of the stent system itself, but also on the guide wire used. The trackability properties could be improved by using an appropriate combination of stent system and guide wire.

“…The lower the push forces felt, the better the traceability. Validation measurements have established that the number of curves is responsible for the difficulty level of the relating model path [26]. The tracking system tested consisted of a PVA-H phantom model or silicon phantom model, an acrylic mold of the model, a sheath, and a connecter.…”

Abstract. OBJECTIVE:In this paper, we investigated the parameters with effective traceability to assess the mechanical properties of interventional devices. METHODS: In our evaluation system, a box-shaped poly (vinyl alcohol) hydrogel (PVA-H) and silicone were prepared with realistic geometry, and the measurement and evaluation of traceability were carried out on devices using load hand force. The phantom models had a total of five curve pathways to reach the aneurysm sac. RESULTS: Traceability depends on the performance of the interventional devices in order to pass through the curved part of the model simulation track. The traceability of the guide wire was found to be much better than that of the balloon and stent loading catheter, as it reached the aneurysm sac in both phantom models. CONCLUSIONS: Observation using the video record is another advantage of our system, because the high transparency of the materials with silicone and PVA-H can allow visualization of the inside of an artery.
