MAUDE Adverse Event Report: MEDTRONIC HEART VALVES DIVISION ENVEO R DELIVERY SYSTEM; AORTIC VALVE, PROSTHESIS, PERCUTANEOUSLY DELIVERED

Model Number ENVEOR-N-US

Device Problems Kinked (1339); Difficult To Position (1467)

Patient Problem No Known Impact Or Consequence To Patient (2692)

Event Date 04/10/2018

Event Type  malfunction  

Manufacturer Narrative

Product analysis: upon receipt at medtronic¿s quality laboratory, the delivery catheter system (dcs) capsule was fully open.The handle was intact.The deployment knob was able to retract and advance the capsule.The trigger moved to fully advance and retracted positions and locked in place when released.The tip-retrieval mechanism was intact.The device was returned with the end cap/screw gear snap fit connected.Voids were observed along the proximal end of the capsule.A kink was observed along the distal end of the inner member shaft near the nose cone.Conclusion: the investigation is in progress.If information is provided in the future, a supplemental report will be issued.

Event Description

Medtronic received information that during the implant of this transcatheter bioprosthetic valve, the valve was recaptured.Fluoroscopy showed a kink in the delivery catheter system (dcs) proximal to the paddle pockets during attempted deployment.There was no separation of the capsule noted.Subsequently, the valve was recaptured, and the system was withdrawn from the patient.A second valve was loaded onto a new dcs and successfully implanted.The patient anatomy was reported to have an angle of 58 degrees.No adverse patient effects were reported.

Manufacturer Narrative

Additional information was received that the valve was too ventricular upon the first deployment attempt and subsequently was recaptured to position the valve more aortic.If information is provided in the future, a supplemental report will be issued.

Manufacturer Narrative

The device history record was reviewed and showed that this product met all manufacturing specifications for product released for distribution.No issues were identified that would have impacted this event.In the first deployment attempt, the valve required to be recaptured to improve implant position.Various factors could have effected valve positioning, such as patient anatomy or physician experience, and the cause of the suboptimal placement could not be determined with the limited information available.The recapture was a feature of the device that allowed for additional attempts at accurately positioning the valve.It was then indicated that the capsule appeared kinked proximal to the paddle pockets, warranting withdrawal and retrieval of the system from the patient.The observed voids along the proximal end of the capsule indicated delamination between the capsule outer polymer and the nitinol frame.This typically occurred when the capsule was subjected to a bending force potentially after tracking through tortuous anatomy, or if a valve had been misloaded.There were no procedural load check images provided, thus the quality of the load could not be determined at this time.The observed kink may have also resulted from use/handling by the user, but a definitive root cause could not be determined.There was no information to suggest a device quality deficiency related to this event.If information is provided in the future, a supplemental report will be issued.
