The device description clearly details a physical, electromechanical device with a pistol grip, hollow shaft, electrical connection, and smoke evacuation system. It is a hardware device used for surgical procedures.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "cutting, and extracting tissue in laparoscopic gynecologic procedures." This describes a surgical tool used on the patient's body, not a device used to test samples from the body in a laboratory setting.
- Device Description: The description details a surgical instrument with a pistol grip, hollow shaft, and features for cutting tissue and managing smoke. This aligns with a surgical device, not an IVD.
- Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing biological samples (blood, urine, tissue samples, etc.) to diagnose diseases or conditions.
- Performance Studies: The performance studies described are bench testing on tissue models and usability evaluations with surgeons, which are typical for surgical devices, not IVDs.
IVD devices are used to examine specimens obtained from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening. The PK Morcellator is a surgical instrument used directly on the patient during a procedure.

Device Description
The proposed PK Morcellator is configured in an ergonomically friendly pistol grip configuration, and includes an axially oriented hollow shaft. The pistol grip integrates the electrical connection cable that allows bipolar RF energy to be supplied by the electrosurgical generator to the tissue site located at the distal end of the hollow shaft. The design of the pistol grip body is such that a clinician may utilize a "ski-pole" grip on the Morcellator body, if that is their preference. The proposed PK Morcellator incorporates an improved smoke evacuation system to provide improved visibility during procedures. Smoke management can alternate between intermittent or constant by activating a trigger lock on the handle.
The hollow shaft of the Morcellator has an operative length of approximately 15 cm, extending distally from the pistol grip body. The surface of the Morcellator shaft is smooth, allowing the device to be introduced to the operative site through a trocar cannula seal, or with the use of the optional obturator, through an abdominal port. To facilitate optimal placement of the device during laparoscopic procedures, a depth stop normally located at the distal end of the pistol grip (at the junction of the pistol grip and Morcellator shaft), may be moved distally along the Morcellator shaft. The shaft has a nominal outer diameter of 15 mm. and a nominal inner diameter of 12 mm. The proximal end of the shaft also includes an elastomeric reducer that permits the passage of a grasper to the operative site and removal of tissue from the operative site, while preventing loss of pnuemoperitoneum.

Human Factors/Usability Engineering: Inputs included user feedback from the predicate device (PKS PlasmaSORD). Usability evaluation involved surgeons with varying experience using bench and animal models. Instructions for use were validated for clarity, functionality, tissue effect, and hazard avoidance. Verification and validation demonstrated that usability characteristics met acceptance criteria.
Containment System Compatibility: Evaluations conducted to demonstrate successful deployment of the PK Morcellator within a containment system (ASC PneumoLiner). Test criteria included insertion/removal and morcellation within the system. Conclusion: PK Morcellator function remained unaffected when used with the PneumoLiner. Additionally, ASC performed an evaluation showing compatibility of the PneumoLiner with different morcellators, including the PK Morcellator, concluding safe and effective use in bench and porcine models.
Key Results: Performance testing demonstrates that the proposed PK Morcellator is substantially equivalent to the predicate device and can be used in conjunction with the PneumoLiner containment device.

Device Description
The proposed PK Morcellator is configured in an ergonomically friendly pistol grip configuration, and includes an axially oriented hollow shaft. The pistol grip integrates the electrical connection cable that allows bipolar RF energy to be supplied by the electrosurgical generator to the tissue site located at the distal end of the hollow shaft. The design of the pistol grip body is such that a clinician mav utilize a "ski-pole" grip on the Morcellator body, if that is their preference. The proposed PK Morcellator incorporates an improved smoke evacuation system to provide improved visibility during procedures. Smoke management can alternate between intermittent or constant by activating a trigger lock on the handle.
The hollow shaft of the Morcellator has an operative length of approximately 15 cm, extending distally from the pistol grip body. The surface of the Morcellator shaft is smooth, allowing the device to be introduced to the operative site through a trocar cannula seal, or with the use of the optional obturator, through an abdominal port. To facilitate optimal placement of the device during laparoscopic procedures, a depth stop normally located at the distal end of the pistol grip (at the junction of the pistol grip and Morcellator shaft), may be moved distally along the Morcellator shaft. The shaft has a nominal outer diameter of 15 mm. and a nominal inner diameter of 12 mm. The proximal end of the shaft also includes an elastomeric reducer that permits the passage of a grasper to the operative site and removal of tissue from the operative site, while preventing loss of pnuemoperitoneum.
Intended Use
"PK Morcellator WA90200A
The PK Morcellator is intended for cutting, and extracting tissue in laparoscopic gynecologic procedures. It is recommended to use the PK Morcellator in conjunction with the PneumoLiner containment device (WA90500US) for removal of uterine tissue."
Comparison with predicate intended use:
The predicate PKS Morcellator (K080093) was cleared with the following intended use statement:
"The Gyrus ACMI PKS Plasma Morcellator is intended for cutting, coring, and extracting tissue in various operative laparoscopy procedures, including laparoscopic general surgical procedures, laparoscopic urological procedures, and laparoscopic gynecologic procedures."
Differences between the proposed and predicate statements:
- . The name has been modified from Gyrus ACMI PKS Plasma Morcellator to PK Morcellator.
- Coring has been deleted from the proposed K161038 intended for use statement. ●
5
Comment: The proposed PK Morcellator has a lip on the distal tip that allows a "peeling" removal of tissue as compared to the predicate "coring" technique.
-
. Laparoscopic general surgical procedures and laparoscopic urological procedures have been deleted from the proposed intended use.
Comment: The bovine tongue tissue model evaluated in this submission is a more appropriate model for laparoscopic gynecological indications. -
The proposed statement now recommends the use the PK Morcellator in conjunction with the PneumoLiner containment device (WA90500US) for removal of uterine tissue
Comment: Validation testing confirmed the compatibility, safety and efficacy of the PK Morcellator when used with the ASC Pneumoliner for the removal of uterine tissue.
The aforementioned differences between the predicate and proposed indications do not affect the safety and effectiveness of the device and do not alter the intended surgical use of the device.
Comparison of Technological Characteristics
The proposed PK Morcellator utilizes bipolar electrosurgical energy to cut tissue which is the same as the predicate PKS Plasma Morcellator. In addition the proposed PK Morcellator is dimensionally similar to the PKS Plasma Morcellator, having similar Morcellator shaft diameters. Like the predicate device the proposed PK Morcellator utilizes a pistol grip Morcellator with a hollow shaft through which a grasper is passed to grasp tissue to be resected. The proposed and predicate morcellators are sterilized for single use only.
The subject and predicate devices have similar technology, principles of operation, performance, dimensions and materials. A side-by-side comparison of the marketed and proposed devices is provided below.

Inputs to the PK Morcellator requirements have included user feedback from PKS PlasmaSORD, which has been in clinical use for over 5 years. The PK Morcellator is an upgrade of the PKS PlasmaSORD to include an integral smoke extraction system to improve visibility, and a beak to promote tissue peeling, and avoid coring.
The subject of usability has been widely considered during the four year development of the PK Morcellator, with the opinions of users regularly sought and fed back into the instrument design. Usability evaluation included surgeons with varying levels of experience and utilized various bench models and an animal model for assessments. The instructions for use were validated to ensure they provide clear and concise statements which convey to the user the correct modes of use, an understanding of the functionality offered, the nature of the tissue effect obtained and how to avoid potential hazards. In summary, the verification and validation activities successfully demonstrated that the usability characteristics of the user interface have met the acceptance criteria.

Containment System Compatibility
During the development of the PK Morcellator, evaluations were conducted to demonstrate the successful deployment of the PK Morcellator in a containment system. The purpose of the compatibility validation was to ascertain that the PK Morcellator device can function as expected in conjunction with the containment system chosen for validation. Test criteria evaluated the insertion/removal of the device, as well as morcellation within the containment system. The overall conclusion, as regards compatibility of the validation of the PK Morcellator device when used in conjunction with the ASC PneumoLiner containment system is that the function of the morcellator remained unaffected.
Additionally, Advanced Surgical Concept (ASC) performed an evaluation to show compatibility of the PneumoLiner Containment Device, with different morcellators, including the PK Morcellator. The purpose of ASC's design validation was to show that the PneumoLiner device can be used safely and effectively by users. Testing in bench models simulating clinical use and a porcine model by trained laparoscopists with a range of experience, demonstrate that the PK Morcellator can be used within the PneumoLiner without any adverse effects on the design or performance of either device. The overall conclusion of was that "the PneumoLiner" device meets user needs and has been shown to be able to be used safely and effectively by users using all of the tested morcellators, including the PK Morcellator.
Conclusion:
Performance testing summarized above demonstrates that the proposed PK Morcellator is substantially equivalent to the predicate device and that the PK Morcellator can be used in conjunction with the PneumoLiner containment device.
