Manufacturer Narrative

The device was returned to stryker sustainability solutions for evaluation.Upon inspection of the received complaint device, it was observed to have been received with the cutting blade in the open position.The cutting blade functionality was tested by manually twisting the drive cable coil on the drive cable plug to open and close the blade, however the blade would not fully close.The complaint device was hooked up to the myosure hologic console to replicate the reported event of, "this item kept rotating after foot control was released and didn¿t stop in the correct position" and "the blade continued to rotate after the unit was supposed to stop, then did not stop in the correct position." after activating the foot pedal on the myosure hologic console, the console cycled through 19 cycles in which the blade failed to fully actuate/close.The blade would spin after letting off the foot pedal.The device was disassembled to inspect the internal shaft assembly.During disassembly it was revealed that the internal wiring was wrapped around the device cable assembly, the results of the visual inspection and functional testing determined that the reported event was confirmed.A review of the dhr supports that the device met all inspection and test criteria prior to release from stryker.Therefore, the reported event could be attributed to: - mechanical failure of the device gear assembly the instructions for use (ifu) state: ¿ before using the myosure tissue removal system for the first time, please review all available product information.¿ use only the myosure control unit to connect to the reprocessed myosure tissue removal device.Use of any other drive mechanism may result in failure of the device to operate or lead to patient or physician injury.¿ if visualization is lost at any point during a procedure, stop cutting immediately.¿ periodic irrigation of the tissue removal device tip is recommended to provide adequate cooling and to prevent accumulation of excised materials in the surgical site.¿ ensure that vacuum pressure >200 mm hg is available before commencing surgery ¿ before using the myosure tissue removal system, you should be experienced in hysteroscopic surgery with powered instruments.Healthy uterine tissue can be injured by improper use of the tissue removal device.Use every available means to avoid such injury.¿ do not use the reprocessed myosure tissue removal device to resect tissue that is adjacent to an implant.When resecting tissue in patients that have implants, assure that: o the reprocessed myosure tissue removal device¿s cutting window is facing away from (i.E.180° opposite) the implant; o the visual field is clear; and o the reprocessed myosure tissue removal device¿s cutting window is engaged in tissue and is moved away from the implant as tissue resection proceeds.¿ in the event an implant becomes entangled with a myosure cutter, the following steps are recommended: o cease cutting immediately: o kink the reprocessed myosure tissue removal device¿s outflow tube to prevent a loss of uterine distension; o disconnect the reprocessed myosure tissue removal device¿s drive cable from the control box; o grasp the end of the reprocessed myosure tissue removal device drive cable with a hemostat or other clamping device; o hold the drive cable hub and tissue removal device to prevent twisting; o open the tissue removal device¿s cutting window by manually twisting the hemostat counterclockwise; and o gently pull the reprocessed myosure tissue removal device into the hysteroscope to detach the myosure device from the implant.Operation 1.Push the power switch to the on (|) position.2.The foot pedal activates tissue removal device operation.The foot pedal turns the motor on and off.Once the foot pedal is depressed, the reprocessed tissue removal device accelerates and rotates to the set speed and continues until the foot pedal is released.3.Press the foot pedal and observe the reprocessed tissue removal device action to verify that the motor runs and that the cutting window is closed as shown in figure 5.4.Introduce the reprocessed tissue removal device through the straight 3 mm working channel of a hysteroscope.5.Under direct hysteroscopic visualization, position the reprocessed tissue removal device¿s side facing cutting window against target pathology.6.Press the foot pedal to activate the reprocessed tissue removal device¿s cutting blade.7.The reprocessed tissue removal device¿s reciprocating action alternately opens and closes the device¿s cutting window to the vacuum flow thereby drawing tissue into the cutting window.8.Cutting takes place when the reprocessed tissue removal device cutting edge rotates and translates across the reprocessed tissue removal device¿s cutting window.Caution: excessive leverage on the reprocessed tissue removal device does not improve cutting performance and, in extreme cases, may result in wear, degradation, and seizing of the cutter assembly.The reported event will continue to be monitored through post-market surveillance.

Event Description

It was reported the device kept rotating after foot control was released and did not stop in the correct position.There was no patient injury or medical intervention and the extended procedure time reported was only minutes.These are commonly used devices that are readily available.
