  • Hemodynamically stable
  • Available for follow-up assessments

You may not qualify if:

  • Inability to infuse at least 2 mL of saline through the catheter
  • Catheter placed less than 48 hours prior to detection of occlusion
  • Catheter used for hemodialysis of pheresis
  • Less than 18 years of age
  • Evidence of mechanical or nonthrombotic occlusion
  • Receipt of any thrombolytic agent within 24 hours of randomization
  • In the opinion of the investigator, subject is at "high risk" for bleeding events of embolic complications, or has a condition for which bleeding constitutes a significant hazard
  • Increased risk for drug extravasation
  • Pregnant, lactating, or actively menstruating women and women of child-bearing potential who are not using adequate contraceptive precautions (e.g. intrauterine device, oral contraceptives, barrier methods, or other contraception deemed adequate by the investigator)
  • Known right-to-left cardiac shunt, patent foramen ovale, or atrial/ventricular septal defect
  • Participation in any other study of an investigational device, medication, biologic, or other agent within 30 days before enrollment and until the 30-day follow up visit
  • Any other subject feature that in the opinion of the investigator should preclude study participation
