This medwatch is not to report a device malfunction, but to report an adverse patient effect during procedure in which an angiodynamics' device was used.As the reported defective device was not returned, angiodynamics is unable to perform a device evaluation.The customer's reported complaint description cannot be confirmed given the nature of the patient serious adverse event.There was no report of angiovac device malfunction during the procedure, hence, no sample was returned for evaluation.The root cause of hemorrhage was likely due to patient stick the previous day.A review of the device history records was performed for the reported packaging and component lots for any deviations related to the reported defect of the complaint.The review confirms that the lots met all material, assembly, and performance specifications.Directions for use is provided with this device and contains the following statements: warnings selection of the patient as a candidate for use with this device and for such procedures as it is intended is the physicians' sole responsibility.The outcome is dependent on many variables including, patient pathology, surgical procedure, and perfusion procedure/technique.The benefits of use of this device must be weighed against the risks including risks of systemic anticoagulation and must be assessed by the prescribing physician.- as with all medical devices, this device and ancillary equipment are to be used by trained physicians only.Specifically, this device is to be used only by medical personnel experienced with initiating and monitoring extracorporeal bypass and by physicians trained and experienced using surgical and/or percutaneous (seldinger) vascular access techniques.Adverse events this device, as do all extracorporeal blood vessel devices, has possible side effects, which include but are not limited to infections, blood loss, thrombus formation, embolic events, vessel, ventricular or valvular damage and complications of percutaneous or surgical insertion techniques.These may occur if the instructions for use are not followed.Possible complications include those normally associated with large bore surgical and/or percutaneous vessel catheterization/cannulation, anticoagulation, extracorporeal circulation and application of intravascular introducer systems which include but are not limited to: death, pulmonary embolism.A review of the angiodynamics complaint system noted no adverse trends for this complaint type and product family.This type of complaint will continue to be monitored for trends.Reference (b)(4).

An angiodynamics clinical specialist reported a patient issue with an angiovac cannula, with dilator.During a procedure, when the operator activated the pump for aspiration, the patient's blood pressure (bp) crashed within 60 seconds.The patient was managed by anesthesia and the angiovac was used for about 45 seconds, at only 0.5lpm with a flow 800rpm.At this time, the patient's bp crashed again, requiring av to be shut off and removed while anesthesia and staff managed and stabilized the patient again.A ct scan discovered that the patient had a retroperitoneal bleed in the groin, which is assumed to be from a previous stick the day before.Once the patient was stabilized with medication, blood and fluid volume, they were sent to the ccu.The patient still required surgery on another day.It was indicated that the reported device is not available to be returned to the manufacturer for evaluation as there was no indication of a device malfunction or failure.
