Submitter: Sicel Technologies, Inc. 3800 Gateway Centre Blvd. Suite 308 Morrisville, NC 27560 Contact: Suzanne Schwaller, Regulatory Affairs Associate Phone: (919) 465-2236 ext. 363 Fax: (919) 465-0153 Prepared: October 10, 2008 | Common or Usual<br>Name: | Patient Radiation Dosimeter | |--------------------------|--------------------------------------------------------------------------------------------------| | Proprietary Name: | DVS, Dose Verification System | | Classification Name: | System, Radiation Therapy, Charged-Particle, Medical<br>Dosimeter, Ionizing Radiation, Implanted | | Manufactured By: | Sicel Technologies, Inc.<br>3800 Gateway Centre Blvd.<br>Suite 308<br>Morrisville, NC 27560 | | | Phone: (919) 465-2236<br>Fax: (919) 465-0153 | {1}------------------------------------------------ Predicate Device(s): Sicel Technologies, Inc. K052118, K061051, K071399, K080004 DVS, Dose Verification System 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. #### Indication 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. {2}------------------------------------------------ ### 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, K071399 and K080004. The indications for use of the SICEL DVS also are the same. The technological features of the SICEL DVS Patient Dose Verification System are the same as the predicate including the use of MOSFET technology and the energy sources measured. The principles of operation are the same as the predicate and there are no changes in control mechanisms. The materials of the dosimetery have not changed and the dosimeter 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 primary difference between the predicate device and the modified device is the addition of the DVS HFT dosimeter to the DVS System. This change involves a change to the performance specifications of the predicate standard dosimeter; specifically, a change has been made to the dose ranges and corresponding accuracies allowing for the use of the dosimeter with hypofractionated radiation treatment plans. The other changes to the system included software, labeling and manufacturing process changes which support the addition of the DVS HFT dosimeter option. 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 efficacv and demonstrated that the device met 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, K080004). {3}------------------------------------------------ Image /page/3/Picture/0 description: The image shows the logo for the U.S. Department of Health & Human Services.
