Leksell Gamma Knife® Icon™ is a teletherapy device intended for stereotactic irradiation of head structures ranging from very small target sizes of a few millimeters to several centimeters, e.g. metastatic tumors, arteriovenous malformations, trigeminal neuralgia, medically refractory essential tremor, meningiomas, vestibular schwannomas, postsurgical pituitary adenomas and recurrent glioblastomas.
Device Description
Leksell Gamma Knife® Icon™ is a radiosurgery system for use in the stereotactic irradiation of intra-cranial structures. Surgery is achieved by delivering a prescribed dose as one or more shots of ionizing radiation to the exact site of the target. Based on preoperative radiological examinations, the Leksell Gamma Knife® Icon™ unit provides highly accurate external irradiation of intra-cranial structures using collimated beams of ionizing radiation. Each unit contains 192 sealed sources of Cobalt 60. The Leksell Gamma Knife Icon system consists of several parts, physically separated into a control room and a treatment room. - The control room contains an operator console and an office cabinet. The . treatment session is controlled and monitored by the operator from the control room. The control room also contains a Leksell GammaPlan computer. - . The treatment room contains the Leksell Gamma Knife unit. A Leksell Gamma Knife unit consists of the radiation unit, the patient positioning system, and a set of covers. A Leksell Gamma Knife Icon unit also includes a Cone Beam CT and an Intra Fraction Motion Management (IFMM) system. The treatment room also contains a camera, patient speakers, a microphone, a treatment room monitor, and a radiation warning lamp. The system is electrically separated into an office side and a medical side. - . The office side consists of the equipment in the control room, as well as the following equipment in the treatment room: a camera, patient speakers, a microphone, a treatment room monitor and the radiation warning lamp. The office side is powered and controlled by the office cabinet in the control room. - . The medical side consists of the Leksell Gamma Knife unit in the treatment room, and is electrically isolated from the office side. The medical side is powered and controlled by a medical cabinet, placed inside the rear cover of the radiation unit.
More Information

No
The summary does not mention AI, ML, or related concepts, and the description focuses on the hardware and control systems of a traditional radiosurgery device.

Yes

The "Intended Use / Indications for Use" states that the device is intended for "stereotactic irradiation of head structures" to treat conditions like "metastatic tumors, arteriovenous malformations, trigeminal neuralgia, medically refractory essential tremor, meningiomas, vestibular schwannomas, postsurgical pituitary adenomas and recurrent glioblastomas," which are all therapeutic applications.

No

The device is described as a "teletherapy device" and a "radiosurgery system" intended for "stereotactic irradiation". It delivers a "prescribed dose" using "ionizing radiation" to treat medical conditions. This indicates a therapeutic function, not a diagnostic one. While it uses preoperative radiological examinations and includes a Cone Beam CT, these are for guiding the treatment, not for diagnosing conditions.

No

The device description clearly outlines a complex hardware system including a radiation unit with Cobalt 60 sources, a patient positioning system, a Cone Beam CT, and an Intra Fraction Motion Management system, in addition to software components.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to detect diseases, conditions, or infections.
  • Device Function: The Leksell Gamma Knife® Icon™ is a teletherapy device that uses ionizing radiation to treat structures within the head. It is a therapeutic device, not a diagnostic one.
  • Intended Use: The intended use clearly states it's for "stereotactic irradiation of head structures" for various conditions. This is a treatment modality.
  • Device Description: The description details a radiosurgery system that delivers radiation doses. It does not mention any analysis of biological samples.

Therefore, the Leksell Gamma Knife® Icon™ falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

Summary of Performance Studies

Testing in the form of module, integration and system level verification was performed to evaluate the performance and functionality of the new and existing features aqainst requirement specification. Regression and re-test of unchanged functionalities in the developed system was done to ensure that the new and updated functionalities did not introduce any undesirable effects.

Design and usability validation of the system has been performed by competent and professionally qualified personnel to ensure that the product fulfils the intended use and user needs. The design and usability validation was also made to ensure that the risk control measures associated with functions related to safety (FRS) for the new functionality was effective.

The system has been subjected to compliance testing to voluntary consensus safety standards, e.g. IEC 60601-1 Ed 3, IEC 60601-1-2 Ed 3, IEC 60601-1-3 Ed 2 and IEC 60601-2-11 Ed 3.

Results from verification and validation testing demonstrate that conformance to applicable technical requirement specification and user needs have been met and safety & effectiveness have been achieved.

9. Intended Use

Leksell Gamma Knife® Icon™ is a teletherapy device intended for stereotactic irradiation of head structures ranging from very small target sizes of a few millimeters to several centimeters, e.g. metastatic tumors, arteriovenous malformations, trigeminal neuralgia, medically refractory essential tremor, meningiomas, vestibular schwannomas, postsurgical pituitary adenomas and recurrent glioblastomas.

10. Technological Characteristics

Leksell Gamma Knife Icon is a radiosurgery system for use in the stereotactic irradiation of intra-cranial structures. Surgery is achieved by delivering a prescribed dose as one or more shots of ionizing radiation to the exact site of the target.

Compared to the previously cleared Leksell Gamma Knife Perfexion (K133565). the Leksell Gamma Knife Icon contains new fixation option of the patient with a mask. including a Cone Beam Computerized Tomography (CBCT) and an Intra Fraction Motion Management (IFMM) system. These additional features will give an option to patients to receive treatment without the need for the attachment of an invasive stereotactic frame.

The fundamental functionality and technical characteristics of the Gamma Knife unit have not changed and are substantially equivalent to the predicate device K133565.

11. Substantial Equivalence

Compared to the previously cleared Leksell Gamma Knife Perfexion (K133565), the Leksell Gamma Knife Icon contains new fixation option of the patient with a mask. including a Cone Beam Computerized Tomography (CBCT) and an Intra Fraction Motion Management (IFMM) system. The CBCT part is substantially equivalent to the predicate device XVI R5.0 (K131965) and the fundamental functionality and technical characteristics of the Gamma Knife unit have not changed and is substantially equivalent to the previously cleared Leksell Gamma Knife Perfexion (K133565).

The conclusion is that the differences in technological characteristics between Leksell Gamma Knife Icon and the predicate devices do not raise questions of safety and effectiveness.
