【正文】 orce required to deploy a PRECISE stent pared to . 018 ? New design to track smoothly over .018” and .014” wires New Tip Design ? Soft material: ? Superior tracking ? Atraumatic crossing Highest flexibility on the market ! New Tip Design The proven . Stent benefits Nitinol material One piece laser cut Micromesh Geometry Multisegmented Design Stent Design . PRECISE Stent Design ? Same fundamental ? Nitinol ? Onepiece laser cut ? 18 ‘V’segments circumferentially ? Minimal foreshortening ( 8%) ? 1 mm flare at both ends ? Struts were tuned to match a SDS and maintain similar radial strength Segment Bridges “V” pattern Segmented Design ? Segmented design – 18 circumferential repeating ‘V’ patterns ? Micromesh geometry – Bridges connect subsequent segments – Bridges alternate direction – Segmentindependence every 2 mm S t e n t R a d i a l R e s i s t i v e F o rc e amp。 C h ron i c O u t w a rd F o rc e 1 . 7 71 . 8 41 . 6 31 . 7 60 . 4 80 . 4 00 . 4 90 . 4 30 . 00 . 20 . 40 . 60 . 81 . 01 . 21 . 41 . 61 . 82 . 0S M A R T 6 x 2 0 P r e ci se 6 x 2 0 S M A R T 8 x 4 0 P r e ci se 8 x 4 0Force (N/cm)RRF C O FRRF and COF 012N / c mS M A R T P R EC I S E D yn al i n k Br ai d e d s te n tRadial Strength of different stents ?
