Event or Problem Description
It was reported that a patient underwent primary breast augmentation with two 440cc mentor memorygel boost breast implants.Post-operatively, the was diagnosed, via physical examination, with right breast capsular contracture (baker grade iv) and device extrusion.As a result, the patient underwent breast implant removal surgery on (b)(6) 2024.
Additional Manufacturer Narrative
On january 9, 2025, mentor received additional information indicating that the patient initially experienced hardening, pain and displacement in the right breast.The patient was put on singulair and other medication but the capsular contracture still progressed to baker grade iv.Eventually the patient developed a large scab on the lower power of the right breast and when the scab came off, the right breast implant became exposed.Further examination diagnosed the patient with bilateral capsular contractures (baker grade iv).The patient underwent bilateral mesh placement, vertical mastopexy, fat grafting, and exchange to the following devices: (right) 325cc mentor memorygel boost breast implant catalog: shpb325 lot: 9717083 sn: (b)(6) and (left) 325cc mentor memorygel boost breast implant catalog: shpb325 lot: 9984567 sn: (b)(6).On january 23, 2025, the mentor failure analysis lab received the device for evaluation.The analysis has begun but is not complete at this time.When the investigational analysis has been completed, a supplemental report will be submitted.This medwatch form is for the right breast prosthesis.Capsular contracture on the left breast will be reported under mrn: 1645337-2025-00614.
Additional Manufacturer Narrative
On january 30, 2025, the product investigation was completed.Device investigation summary: the product was returned to mentor for evaluation.Mentor conducted a visual inspection of the returned device.During visual evaluation, no apparent damage or visual anomalies were observed on the smo ro high pro boost gel440cc returned device.Regarding the reported capsular contracture condition, there are not enough details to determine the factors that may have caused this condition.Capsular contracture in the patient¿s breast might be the result of the body¿s individual physiological response to the implantation of a foreign object in soft tissue.Further, capsular contracture is a known complication associated with these devices and is referenced in our current product insert data sheet.The american society of plastic surgeons recommends and encourages member surgeons to always submit breast implants, capsule, and effusion to pathology for examination.Extrusion may occur when the wound has not closed or when tissue covering the implants weakens.The incidence of extrusion has been shown to increase when undue pressure is applied on the tissue located over the device, trauma to surrounding tissues may lead to thrombosis, delayed wound healing, improper size, placement, larger sized implants, use of steroids in the surgical pocket and microwave diathermy.Radiation therapy has been reported to increase the likelihood of extrusion.Extrusion may require additional surgery and possible removal of the implant, which may result in additional scarring and/or loss of breast tissue.As part of mentor's quality process, all devices are manufactured, inspected, and released according to approved specifications.Based on the results of this investigation, it was determined that the product met the manufacturing release criteria: since no malfunction was observed during the investigation.No corrective and preventive action (capa) is required now.
