It was report that during an angioplasty the radiologist inflated the balloon to 5 atm and the balloon burst, possibly circumferentially ( mdr # 1820334-2016-00838).When the radiologist tried to remove the balloon catheter it seemed stuck and then a piece broke off the end, remaining inside the patient.A larger sheath and snare were used to capture the piece of balloon that was in the patient anatomy (mdr # 1820334-2016-00820).A section of the device did not remain inside the patient's body.The alleged incident reportedly prolonged the procedure.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.

(b)(4).Investigation - evaluation: a review of the complaint history, drawings, device history record, documentation, instructions for use (ifu), manufacturing instructions, specifications, quality control and visual inspection of the returned device was conducted during the investigation.The device is shipped with an ifu that describes the intended use, specific items are addressed such as: do not exceed rated burst pressure.Rupture of balloon may occur.Adhere to balloon inflation pressure parameters in the compliance card insert.Over-inflation may cause rupture of the balloon, with resultant damage to the vessel wall.Use of a pressure gauge is recommended to monitor inflation pressures.Do not use a power injector for balloon inflation or injection of contrast medium through catheter lumen marked "distal." rupture may occur.Visual inspection of the returned product shows signs of a linear rupture and a circumferential separation.The distal segment of the balloon is crumbled, indicative of an attempt to pull the device through a sheath against ifu.The complaint device was not returned therefore, no physical examinations could be performed; however, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.Review of device history record shows no nonconforming events which could contribute to this failure mode.Based on the information provided, the catheter was reported to burst at nominal pressure 5 atm.Patient anatomy and disease state is unknown.The root cause for the initial rupture is unknown.The root cause of the separation is due to off label removal of device through the sheath.We will continue to monitor for similar complaints.Per the risk assessment no further action is required.
