Indications, Safety, and Warnings

STINGRAY Guidewire with Hydrophilic Coating

Indications, Safety, and Warnings

CAUTION: Federal law (USA) restricts this device to sale by or on the order of a physician. Rx only. Prior to use, please see the complete “Directions for Use” for more information on Indications, Contraindications, Warnings, Precautions, Adverse Events, and Operator’s Instructions.


The Stingray Catheter is indicated for directing, steering, controlling, and supporting a guidewire in order to access discrete regions of the coronary and peripheral vasculature. When used as part of the System consisting of the CrossBoss™ Catheter, Stingray Catheter and Stingray Guidewire, the Stingray Catheter is indicated for use to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions [CTOs]) prior to PTCA or stent intervention.


  • Not intended for use in the cerebral vasculature.


  • Only physicians thoroughly trained in interventional procedures should use the Stingray Catheter.
  • To reduce the potential for vessel damage, the inflated balloon should only be used in vessels that are ≥2.5 mm in diameter as measured proximal and distal to the inflation site.
  • Balloon pressure should not exceed the rated burst pressure. Use of a pressure monitoring device is recommended to prevent over pressurization.
  • Use only the recommended balloon inflation medium.
  • Do not advance or retract the Stingray Catheter unless the balloon is fully deflated under vacuum.
  • Pay special attention when directing a guidewire out a side port. Never push, withdraw or torque components that meet resistance. Device kinking/breaking or vessel damage may occur. Fluoroscopy should always be used to aid device manipulation.


  • In coronary applications, the Stingray Catheter should only be used in hospitals where emergency coronary bypass surgery can be immediately performed in the event of a potentially injurious or life threatening complication.
  • Before insertion of the catheter, administer appropriate anticoagulant and vasodilator therapy.
  • The Stingray Catheter should be handled with care. Prior to use and during the procedure, inspect the packaging and catheter for bends, kinks, or other damage. Discontinue use if the catheter becomes damaged.
  • Do not expose to organic solvents.
  • Always use wire support for advancement, manipulations, and withdrawal of the Stingray Catheter.
  • The Stingray Catheter should only be manipulated under fluoroscopic observation.


Potential adverse events include, but are not limited to, the following:

  • Acute myocardial infarction
  • Vessel trauma that may require further intervention or surgical repair
  • Hemorrhage or hematoma
  • Artery spasm
  • Embolism
  • Stroke
  • Neurological deficit
  • Drug reactions, allergic reaction to contrast media
  • Infection
  • Recurrence of angina
  • Chest discomfort
  • Bleeding from the catheter insertion point
  • Bruising at the catheter insertion point
  • Ischemia due to restenosis of the dilated segment
  • Ventricular failure
  • Dissection or thrombosis with vessel occlusion
  • Arterial Perforation (Surgery required)
  • Blood Toxicity
  • Toxicological response
  • Fever
  • Infection at skin puncture site
  • Deterioration of kidney function/kidney failure
  • Provocation of heart attack/stroke
  • Surgery to recover failed devices
  • Surgery to repair a failed procedure
  • Prolonged procedure time
  • Occlusion of a branch of coronary artery
  • Myocardial infarction with release of CK-MB into circulation
  • Death
  • When failures of PTCA occur, they are often treated using coronary artery bypass surgery
