Manufacturer¿s ref.No: (b)(4).The purpose of this mdr submission is to include the additional event information received on 23-dec-2022 and 27-dec-2022.This mdr submission also contains a correction to a concomitant product.[additional information]: on 23-dec-2022, additional information was received.Per the information, the physician reported that the complaint pulserider anrd ¿had gone down when angiography was taken due to possible coil compaction.There was no negative impact on the patient.The image taken on postoperative one day showed that the complaint pulse rider was still attached to the neck, but a gap was seen between the complaint pulserider and the coil mass around one month after the procedure.Therefore, there was a possibility of compaction, and this angiography was performed.The arch of the complaint pulse rider was caught on pca and kept, and a coil entangled with the arch was rolled out in the blood vessel between the coil mass and complaint pulse rider, but there was no negative impact such as thrombosis on the patient.The diameter of the mother vessel was about 3.4 -3.5 mm at 1 cm from the neck.¿ the physician also commented that, ¿the size may not be suitable and the complaint pulse rider had gone down.¿ he wanted to know if there are other cases like this.On 27-dec-2022, the lot number 3074237323 was provided for the pulserider anrd.On 27-dec-2022, additional clarifying information was received from the japan team.Per the information, coil compaction was suspected around one (1) month after the procedure was completed.Angiography was taken around one month after the procedure and compaction was suspected as there was a space between the coil mass and the pulserider anrd.There was coil entanglement, ¿but the physician could not identify which coil.¿ the clarifying information included the following: in (b)(6) 2022, on post-operative day 1, an angiography was taken and it was confirmed that the pulserider anrd was located in the desired location.In (b)(6) 2022, one month after the procedure, a follow-up angiography was taken and it was confirmed that there was a space between the coil mass and the pulserider anrd, so a potential compaction was suspected.A three-month follow-up angiography was taken in (b)(6) 2022, and it was confirmed that the pulserider anrd had migrated proximally.The arches of the pulserider anrd were caught by the posterior cerebral artery (pca), and one of the coils which was entangled with the pulserider anrd arches became protruded into the space between the coil mass and the pulserider anrd.However, there was no negative patient impact such as embolization.The physician commented that the size of the pulserider anrd might not have been suitable for the inner diameter of the parent vessel, which was approximately 3.4mm to 3.5mm at approximately 1cm from the aneurysm neck.The pulserider anrd may have migrate due to the selected size not being suitable.Vessel perforation is an adverse event reported in the ifu of the galaxy g3 mini microcoil device and the pulserider anrd device.Such an event can result in a cerebral hemorrhage, also a known complication associated with the use of both devices (pulserider anrd and galaxy g3 mini microcoil) as mentioned in their instructions for use (ifus).Per the event description, it was the galaxy g3 mini that was reported to have penetrated the aneurysm and caused the bleeding.However, the relationship between the pulserider anrd device and cerebral bleeding still cannot be excluded.In addition, coil compaction occurred, which may increase the risk of aneurysm rupture and possibly require additional intervention.Therefore, these events will be conservatively reported to the fda with the classification of ¿serious injury.¿ the file will be re-reviewed if additional information is received at a later date.Updated sections: b.4, g.3, g.6, h.2, h.6, h.10, h.11, and concomitant products.This is one of 4 products involved with the reported complaint.The associated manufacturer report numbers are: 3008114965-2022-00599, 3008114965-2022-00600, 3008114965-2022-00869, and 3008114965-2022-00870.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.The incorrect product galaxy g3 xsft 2.5mm x 3.5cm was added as a concomitant in the initial medwatch report.The correct concomitant product is galaxy g3 2.5mm x 5cm.
