Reprocessed MyoSure REACH Tissue Removal Device Description
The MyoSure Tissue Removal System consists of the following procedural
components:
- Control Unit
- Reprocessed Tissue Removal Device (Reprocessed Single Use Device)
- Foot Pedal
The sterile, reprocessed hand-held tissue removal device is used to
hysteroscopically remove intrauterine tissue. It is connected via a flexible
drive shaft to a motorized control unit. A foot pedal allows the user to
control the reprocessed tissue removal device by turning the motor in the
control unit on and off.
Indications for Use
The Reprocessed MyoSure REACH Tissue Removal Device is intended for
intrauterine use by trained gynecologists to hysteroscopically resect and
remove tissue such as: Submucous myomas, endometrial polyps and retained
products of conception.
Contraindications for Use
The MyoSure Tissue Removal System should not be used with pregnant patients or
patients exhibiting pelvic infection, cervical malignancies, or previously
diagnosed endometrial cancer.
Warnings and Precautions
The brief operating instructions in this guide will make the system easier to use. As with any surgical instrument, there are important health and safety considerations. These are as follows:
- WARNING – Please consider pre-operative imaging prior to the procedure to assess the patient for evidence of placental invasion of the myometrium. In the immediate postpartum phase, removal of retained products of conception (RPOC) in the setting of known or suspected placenta acreta, placenta increta or placenta percreta poses a risk of significant and potentially life threatening bleeding.
- Before using the MyoSure Tissue Removal System for the first time, please review all available product information.
- 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.
- 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.
- DANGER: Risk of explosion if used in the presence of flammable anesthetics.
- WARNING – Exercise extreme caution when resecting tissue in patients who have implants that extend into the uterine cavity.
- 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:
- The Reprocessed MyoSure Tissue Removal Device’s cutting window is facing away from (i.e. 180° opposite) the implant;
- the visual field is clear; and
- 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:
- cease cutting immediately:
- kink the Reprocessed MyoSure Tissue Removal Device’s outflow tube to prevent a loss of uterine distension;
- disconnect the Reprocessed MyoSure Tissue Removal Device’s drive cable from the control box;
- grasp the end of the Reprocessed MyoSure Tissue Removal Device drive cable with a hemostat or other clamping device;
- hold the drive cable hub and tissue removal device to prevent twisting;
- open the tissue removal device’s cutting window by manually twisting the hemostat counterclockwise; and
- gently pull the Reprocessed MyoSure Tissue Removal Device into the hysteroscope to detach the MyoSure device from the implant.
- If this unit is configured as part of a system, the entire system should be tested for compliance with IEC 60601-1-1.
- If the leakage current of the configured system exceeds the limits of IEC 60601-1-1, install an appropriately rated UL 2601-1/IEC 60601-1 approved isolation transformer and retest the system.
- The use of accessory equipment in the patient vicinity not complying with the equivalent medical safety requirements of this equipment may lead to a reduced level of safety of the resulting system. The use of accessory equipment outside the patient vicinity not complying with medical or otherwise appropriate safety requirements may lead to a reduced level of safety of the resulting system.
- Use of an accessory, transducer, or cable, other than those specified by Hologic ® may result in increased emissions or decreased immunity of the MyoSure Hysteroscopic Tissue Removal System.
Precautions
- The tissue removal device should be stored at room temperature, away from moisture and direct heat.
- Do not use after expiration date.
- Do not use the device if the sterile package is open or appears compromised. Do not use the device if damage is observed.
- To assure optimal performance, replace the tissue removal device after 2 hours of cutting time.
- The reprocessed tissue removal device is intended for single use only. Do not re-sterilize. Do not lubricate tissue removal device. Discard tissue removal device assembly after use.
- DO NOT attempt to sharply bend the flexible drive cable in a diameter of less than 8 inches (20 centimeters). A sharply bent or kinked drive cable may cause the control unit to overheat and stop. During a procedure, a minimum distance of 5 feet (1.5 meters) should be maintained between the control unit and the tissue removal device to allow the drive cable to hang in a large arc with no bends, loops, or kinks.
- DO NOT rotate the tissue removal device >180° if the tissue removal device is not running. The cutting window may open up which will lead to inability to maintain distension. If such situation occurs, just tap the foot pedal once or twice to run the tissue removal device; the cutting window will then close automatically.
- Use only with 10-550 controller. Using the device with the 10-500 controller may result in an open cutting window which could lead to the inability to maintain distension. If such a situation occurs, tap the foot pedal once or twice to run the tissue removal device; the cutting window will then close automatically.
- If it appears that the tissue removal device’s cutter blade has stopped rotating during a procedure, check to ensure that all connections to the tissue removal device and the control unit (both mechanical and electrical) are secure and that the drive cable has not wrapped into a loop.
- Exercise care when inserting or removing the device. Insertion and removal of the device should be performed under direct visualization at all times.
- To avoid perforation, keep the device tip under direct visualization and exercise care at all times when maneuvering it or cutting tissue close to uterine wall. Never use the device tip as a probe or dissecting tool.
- Exercise care when inserting or removing the device. Excessive bending of the device distal tip can cause the tissue removal device’s cutter to come out of the cutting window. If such damage occurs, replace the device immediately.
- Do not allow the rotating portion of the tissue removal device to touch any metallic object such as a hysteroscope or sheath. Damage to both instruments is likely. Damage to the tissue removal device can range from a slight distortion or dulling of the cutting edge to actual fracture of the tip in vivo. If such contact does occur, inspect the tip. If you find cracks, fractures, or dulling, or if you have any other reason to suspect a tissue removal device is damaged, replace it immediately.
- Do not operate the tissue removal device in the open air for an extended period, as the lack of irrigation may cause the tissue removal device to overheat and seize.
- Excessive leverage on the tissue removal device does not improve cutting performance and, in extreme cases, may result in wear, degradation, and seizing of the inner assembly.
- Do not sterilize or immerse the control unit in disinfectant.
- Do not cool the tissue removal device by immersing it in cold water.
- Electrical safety testing should be performed by a biomedical engineer or other qualified person.
- This equipment contains electronic printed circuit assemblies. At the end of the useful life of the equipment it should be disposed of in accordance with any applicable national or institutional related policy relating to obsolete electronic equipment.
Electromagnetic Safety
