• Submission Type: Traditional
• Regulation: 21 CFR 892.5050
• Device Class: Class 2

Intended Use

The Outlook system is indicated for use as a NMR device that produces images that: (1) correspond to the distribution of protons exhibiting NMR, (2) depend upon the NMR parameters (proton density, flow velocity, spin-lattice relaxation time (TI), and spin-spin relaxation time (T2)) and (3) display the soft tissue structure of the head and whole body. When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis. The MRGP Basic Package is designed to support and guide diagnostic interventional procedures, such as needle biopsies and drainages.

Device Story

MRGP Basic Package is an optional hardware accessory for Picker Outlook and Outlook Proview MRI systems. It facilitates diagnostic interventional procedures (e.g., needle biopsies, drainages) by providing in-room visualization and scan control. Components include a foot pedal for scan initiation, kneeling pads for physician ergonomics, an MR-compatible procedure light, a multipurpose coil with disposable covers, and an in-room LCD or 36" display. The device utilizes existing standard MRI software and sequences. Used in the scan room by physicians to guide interventional instruments in real-time. Output consists of visual MR images displayed in-room, allowing the physician to monitor needle placement or drainage progress, thereby improving procedural accuracy and patient safety.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing and comparative technical specifications against predicate devices.

Technological Characteristics

Hardware package for 0.23T MRI systems. Includes in-room LCD/36" displays, foot pedal, MR-compatible lighting, and multipurpose RF coils with disposable protective covers. Uses standard MRI sequences (2D/3D gradient echo, FSE, single-shot FSE). Ergonomic accessories include kneeling pads. System is non-sterile; user-provided sterile drapes are required for magnet poles. Connectivity is integrated with the host MRI system.

Indications for Use

Indicated for patients requiring diagnostic interventional procedures, such as needle biopsies and drainages, guided by MRI imaging of the head and whole body.

Regulatory Classification

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.

Predicate Devices

• Siemens Magnetom Open MR Guided Procedures Package (K955389)
• Picker Outlook System Enhancement Package (K974844)

Dear Dr. Keeler:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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, 1976, 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). 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 III (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification"(21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number [phone] or [phone], or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
