As the reported device was not returned, angiodynamics is unable to perform a device evaluation.The customer's reported complaint description of patient allergic reaction cannot be confirmed given the patient centric nature of this event.There was no reported fiber malfunction during the procedure, just patient allergic reaction that cleared on its own after 15-20 minutes.A definitive root cause for the patient reaction during the procedure could not be determined.A potential contributing factor to patient allergic reaction is the tumescent that is typically injected during vein ablations.A review of the device history records was performed for the indicated lots for any deviations related to the reported failure mode of the complaint.The review confirms that the lots met all material, assembly and performance specifications; i.E.No ncr associated with reported failure mode.Labeling review: the instructions for use (ic 393) which is supplied to the end user with this catalog number states, "the potential complications include but are not limited to the following: vessel perforation, thrombosis, pulmonary embolism, phlebitis, hematoma, infection, skin pigmentation alteration, neovascularization, paresthesia due to thermal damage of adjacent sensory nerves, anesthetic tumescence, non-target irradiation, hemorrhage, necrosis, dehp exposure, skin burns and pain".The user manual (man/31/0075), which is supplied to the user with this unit contains the following warnings and statements: "clinical warnings: as with any conventional surgical operations, adverse reactions may occur following treatment", "irradiation of any substance or material other than the target treatment of varicose veins and varicosities may result in a laser burn", "contraindications: the venacure 1470 laser is contraindicated for: · patients with thrombus in the vein segment to be treated · patients with an aneurysmal section in the vein segment to be treated · patients with peripheral artery disease as determined by an ankle-brachial", and, "potential complication: the potential for complications exists, including: · vessel perforation · thrombosis· pulmonary embolism· phlebitis· hematoma· infection· skin pigmentation alteration· neovascularization· paresthesia due to thermal damage of adjacent sensory nerves· anesthetic tumescence· non-target irradiation· hemorrhage· necrosis· dehp exposure· skin burns and pain(this is not an exhaustive list.)".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).Reference reports: (b)(4) 1st event: 1319211-2022-00003.(b)(4) 2nd event 1319211-2022-00004.
