Event Description

Medtronic received report that during deployment of the pipeline (ped), the pipeline would not open distally.After multiple attempts of trying to get the pipeline to open, the pipeline was removed in anticipation of using a different pipeline of the same size.After removal of pipeline, an angiogram was taken, and clot was found in location of intended distal landing zone of pipeline.There was also either vasospasm or clot in superior division of mca.The patient was given integrilin to treat clot.Clot appeared to resolve.Device is being sent back due to its inability to open correctly in vessel.When device was inspected on table, it appeared to be slightly deformed in shape.The ped¿s distal section was placed in a bend in the anatomy.More than 50% of the device was deployed.The ped was resheathed less than or equal to 2 times.The ped was resheathed with the phenom 27 catheter and removed.The devices were prepared and used per the instructions for use.A new device was used to treat the patient.Post procedure angiography showed minimal changes from previous angio.The patient was on dual antiplatelet treatment.The patient was undergoing treatment of a previously ruptured pcom aneurysm that was initially coiled, at the time of the initial rupture.The aneurysm was saccular, the max diameter was 10mm and the neck was 8mm.The distal landing zone was 3.8mm and the proximal was 4.2mm.The vessel anatomy was moderate.
