During a left heart cath, a 6f radial sheath folded in on itself when entering the radial artery causing the artery to spasm upon entry that was treated with a cocktail.The procedure was successfully completed by using a non-cordis sheath.The product was not returned for analysis.A product history record (phr) review of lot 18071333 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.Without the return of the device or images for analysis, the reported customer event ¿catheter sheath introducer-damaged¿ could not be confirmed.Procedural/handling factors such as failure to activate the hydrophilic coating by soaking the device in heparinized saline or similar isotonic solution may have contributed to the reported event.Arterial spasm is a known potential adverse event associated with any interventional procedure where devices are introduced into the vasculature.Local vasospasm can be caused by the device manipulations inherent in any procedure causing endothelial irritation.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿soak the csi in sterile heparinized saline or similar isotonic solution to activate the hydrophilic coating.Possible complications include, but are not limited to: abrupt vessel closure, additional intervention, allergic reaction (device, contrast medium and medications), air embolism, infection, intimal tear, hematoma at puncture, hemorrhage, inflammation / infection / sepsis, ischemia, perforation of vessel wall, thrombus formation, peripheral nerve injury, pain, vascular complications (e.G.Intimal tear, dissection, pseudo aneurysm, perforation, rupture, spasm, occlusion¿ based on the information available and the phr review, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
