The description focuses on hardware components, data storage, and basic software for data review and reporting, with no mention of AI or ML algorithms for analysis or decision support.
No
The device is intended to verify treatment planning and radiation dose, and to measure in vivo radiation dose, serving as an adjunct to treatment planning. It does not actively treat or deliver therapy.
No
The device is intended to verify treatment planning and radiation dose, not to diagnose a condition or disease. It measures the in vivo radiation dose received at the tumor periphery, tumor bed, and/or surrounding normal tissues for validation of the prescribed dose.
No
The device description clearly outlines multiple hardware components: an implantable dosimeter, an insertion tool, and a reader system (wand and base station). While it includes software (Plan and Review Software and Dosimetry Database), it is not solely software.
Based on the provided information, the DVS (Dose Verification System) is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- DVS Function: The DVS system measures radiation dose in vivo (within the living body) using an implanted dosimeter. It does not analyze specimens taken from the body. Its purpose is to verify radiation dose delivery during therapy, not to diagnose a condition or analyze biological samples.
Therefore, the DVS falls outside the scope of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The DVS (Dose Verification System) is intended for use in radiation therapy to verify treatment planning and radiation dose to tissue and organs in or near the irradiated areas of a patient.
The DVS system is specifically indicated for breast and prostate cancer to measure photon beam therapy and as an adjunct to treatment planning to permit measurement of the in vivo radiation dose received at the tumor periphery, tumor bed and/or surrounding normal tissues for validation of the prescribed dose.

Device Description
The DVS, Dose Verification System consists of four sub-systems: the DVS Implantable Dosimeter for measuring radiation dose in vivo, the DVS Insertion Tool for implanting the dosimeter during percutaneous procedures, the DVS Reader System (Wand and Base Station) for powering the dosimeter and providing a user interface when taking dose measurements, and the DVS Data System (Plan and Review Software and Dosimetery Database) for storing and reporting patient data and for storing dosimeter information. The dosimeters use a MOSFET, Metal Oxide Semiconductor Field Effect Transistor, as a sensing mechanism. The dosimeter is factory calibrated and powered by the Reader Wand utilizing electromagnetic energy. The dosimeter contains a transmitter, to transmit threshold voltage readings to the reader. It is radioopaque and thus registers on computed tomography scans as a point of interest whereby a point dose may be determined. Patients are implanted prior to radiotherapy. Information on the patient's therapy, dose planning, point dose at the dosimeter, dosimeter serial number and calibration files are entered into the Plan and Review software and stored in the Dosimetry Database. At each therapy fraction the dosimeter is read pre- and post-therapy using the Reader Wand and Base Station. This translates into a daily fractional dose. The patient's daily and cumulative dose may be reviewed via the Plan and Review software. Because the Plan and Review software and Dosimetry Database are designed to be stored on a server, multiple users may be logged into the system at any one time. Reports on the patient's daily and cumulative dose history may be printed using the Plan and Review software.

§ 892.5050 Medical charged-particle radiation therapy system.
(a)
Identification. A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Comparison with Predicate Device:
The intended use of this SICEL DVS is identical to the predicate device, the DVS Dose Verification System in K052118, K061051, and K071399. The indications for use of the SICEL DVS also are the same.
The technological features of the SICEL DVS Dosimeter are the same as the predicate including the use of MOSFET technology, the calibration method, dose range, and energy sources measured. The dosimeter performance specifications are the same and have not changed. The principle of operation is the same as the predicate. The tissue contacting materials are the same and the sterilization method is the same. The insertion tool design, materials, and sterilization are the same. The Reader design and performance specifications are the same and have not changed. The Data System is the same and has not changed.
The primary difference between the predicate device and the modified device is the change to the dosimeter's potting epoxy used to secure and position the electronics within the biocompatible glass capsule. Other changes include minor dimensional changes, minor changes to the electronics components, and minor changes to the Reader software and accompanying Operator's Manual. Details of the substantial equivalence comparison are provided.
Furthermore, verification and validation testing based on the risk analysis, provided information sufficient to determine that the modifications did not have an effect on safety or efficacy and demonstrated that the device met pre-determined acceptance criteria based on performance specifications. The testing demonstrated that the modified device is substantially equivalent to the predicate device and performs as well as the predicate device. The verification and validation results are provided within the 510(k).
Thus, the DVS, Dose Verification System is substantially equivalent to the DVS, Dose Verification System (K052118, K061051, K071399).

Dear Ms. Carrea:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1796, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
