Cannula should exit patient parallel to each other and spaced ~ 4... cm apart to match AB5000 Ventricle • If needed, use supplied tubing extensions • Ensure restraints are properly secured • Use the white threaded cannula restraint marked with a red arrow with the Hemashield ® outflow cannula; use white cannula restraint without red arrow for inflow cannula  LVAD  RVAD  4... cm Cannula  (b)  1-2 mm gap when restraint fully seated  Fully seat cannula end to the bottom of barb  (c) (a)  • Apply sterile lubricant (provided) to: (a) threads located on restraint inner diameter; (b) matching threads at base of connector barb; (c) outside of cannula • DO NOT allow lubricant to contact the outside or inside of connector barb or the inside of cannula  ABIOMED 24-HOUR SUPPORT 800-422-8666  For more information on the BVS® 5000 / AB5000TM Systems see: http://www... iomed... m/clinical_information/ifus_manuals... m 0505-2609 Rev...
