Indications for Use
The Gyrus ACMI PK® Superpulse® System Generator is intended for use with Gyrus ACMI PK® Bipolar Instruments, Olympus TURis Bipolar Electrodes, PK® Endourology Electrodes with PK @ resectoscope or urological endoscope with 5 Fr or larger working channels and PK® Electrodes used in open, laparoscopic, and endourology procedures for cutting, coagulation, removal or ablation of soft tissue and where associated hemostasis is required in urological electrosurgical procedures. The Gyrus ACMI PK® Superpulse® System is intended for use for ablation, removal, resection and coagulation of soft tissue and where associated hemostasis is required in open, endoscopic and laparoscopic surgical procedures. The device is intended for use by qualified medical personnel trained in the use of electrosurgical equipment.
Device Story
The PK® SuperPulse® System is an electrosurgical generator used in open, laparoscopic, and endourological procedures. It delivers bipolar energy to compatible electrodes (Gyrus ACMI PK® and Olympus TURis) for soft tissue cutting, coagulation, removal, or ablation. The system includes a saline monitoring feature that senses impedance to ensure saline is present before activation, preventing use in non-approved irrigants like glycine. The generator is operated by trained medical personnel in clinical settings. The system provides feedback via warning messages if impedance exceeds a fixed threshold. The device benefits patients by enabling precise tissue management and hemostasis in saline environments.
Clinical Evidence
Bench testing only. No clinical data provided.
Technological Characteristics
Electrosurgical generator with bipolar output. Features a saline detection circuit that monitors impedance to ensure saline environment before activation. Includes a specific instrument ID band for Olympus TURis cable connectivity. Software-controlled saline monitoring prevents activation in non-saline irrigants. Operates at low power levels for impedance sensing, consistent with predicate UES-40 technology.
Indications for Use
Indicated for ablation, removal, resection, and coagulation of soft tissue and associated hemostasis in open, endoscopic, and laparoscopic surgical procedures, including urological electrosurgical procedures. Intended for use by qualified medical personnel trained in electrosurgical equipment.
Regulatory Classification
Identification
An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.

#### Intended Use
The Gyrus ACMI PK® Superpulse® System Generator is intended for use with Gyrus ACMI PK® Bipolar Instruments, Olympus TURis Bipolar Electrodes, PK® Endourology Electrodes with PK @ resectoscope or urological endoscope with 5 Fr or larger working channels and PK® Electrodes used in open, laparoscopic, and endourology procedures for cutting, coagulation, removal or ablation of soft tissue and where associated hemostasis is required in urological electrosurgical procedures.
### Product Description
The proposed PK ® SuperPulse® System Generator and its software will be modified to allow the use of the Olympus TURis resectoscope and associated instruments. This functionality would be in addition to the existing released support for the Gyrus ACMI resectoscopes and compatible electrodes.
Modifications include:
- Modification to the Superpulse® software to add an additional instrument .
band to allow the connection of a TURis specific connector cable.Addition
of a saline monitoring facility to ensure that energisation is only applied to
the TURis connector cable when a saline environment is
sensed.Modification to User Manual to cover the above changes
The target applications and intended use for the PK® Superpulse® System Generator with the new software are unchanged from the previously marketed PK® Superpulse® System.
## Technological Characteristics and Substantial Equivalence
A new ID band has been assigned for a new instrument connection cable that will support the range of Olympus TURis instruments (The name TURis is derived from transurethral resection in saline).
Default settings and adjustments will be available to all Olympus TURis instruments connected to this TURis cable. The default settings and range of adjustment for these instruments have been provided by OWI (Olympus Winter und Ibe) located in Hamburg, Germany.
A new saline detection feature will be incorporated in the SuperPulse® software to ensure that saline is present before activation will be allowed to occur with Olympus TURis electrodes.

## Continued...Technological Characteristics and Substantial Equivalence
The technical risk for the software release is low. This is because the project is replicating a feature already available on the Olympus UES-40 generator; information about the implementation of this feature is readily available. The performance of the saline detection feature should be such that it operates in a similar manner to that of the existing Olympus UES-40 generator used for TURis accessories. The power level used to sense the impedance is to be kept similar to the same low level as the UES-40 as this has been clinically accepted in the marketplace.
The purpose of the saline detection feature is to prevent activation in non-approved irrigants other than saline (e.g. glycine) that are typically used in monopolar based urology procedures. The saline detection facility will result in a warning message if the impedance of the tissue / saline is sensed above a fixed threshold. The new feature will be specific to the Olympus TURis band and existing alternative non-TURis product performance will be unchanged.
The proposed Gyrus ACMI PK® SuperPulse® System will have the same indications for use as the existing/predicate and its intended use will differ only in that it will be intended to support the additional Olympus TURis cable and electrodes. In summary, the PK® SuperPulse® System Generator is substantially equivalent to the predicate device and presents no new questions of safety or efficacy.
