Intended Use
The Hammersmith Endocavitary Coils do not change the intended use of the Picker MR system with which they are used. Picker MR systems are intended for use as NMR devices that produce images that: (1) correspond to the distribution of protons exhibiting NMR, (2) devend upon NMR parameters (proton density, flow velocity, spin-lattice relaxation time T1, 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 vield information that can be useful in the determination of a diagnosis. The Hammersmith Endocavitary Coils are indicated for use in the following anatomic regions and with the designated nuclei: Anatomic Regions: The Anus or Prostate by insertion into the rectum, and the Cervix by insertion into the vagina Nuclei Excited: Hydrogen
Device Description
These three separate receive-only coils are for imaging the anus, prostate and cervix. The coils are designed to be inserted in either the rectum or vagina before imaging. The Hammersmith Endocavitary Coils are similar to the Philips Endo-Cavitary Coil in that they are reusable. However, unlike the Philips Endo-cavitary MRI Coil, they are rigid structures that do not contain an inflatable latex balloon. This difference in the design eliminates the need for limiting the number of times the Hammersmith Coils can be used, allows for fixed tuning and matching, and reduces the image artifacts due to susceptibility effects from air. Instead, the shape and dimensions of the Hammersmith Endocavitary Coils are similar to ultrasound probes used in endocavitary applications.
More Information

No
The document describes a passive receive-only coil for MRI, which is a hardware component. There is no mention of software, algorithms, or any processing that would suggest the use of AI/ML.

No
The device is described as an NMR device that produces images to aid in diagnosis, not to treat or prevent a disease or condition.

Yes
The "Intended Use / Indications for Use" section states that the MR system (which these coils are used with) produces images that "When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis." This indicates its role in the diagnostic process.

No

The device description clearly describes physical coils designed for insertion into the body, which are hardware components, not software.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Hammersmith Endocavitary Coils are described as "receive-only coils" used in conjunction with an MRI system. Their purpose is to improve the quality of MRI images of specific anatomical regions (anus, prostate, cervix) by being inserted into the body.
  • Intended Use: The intended use clearly states that the coils "do not change the intended use of the Picker MR system," which is to produce images for diagnosis based on the physical properties of protons in the body. The images are then interpreted by a trained physician.
  • No Sample Analysis: The device does not analyze any biological samples taken from the patient. It is a component of an imaging system.

Therefore, the Hammersmith Endocavitary Coils are a medical device used for imaging, not an in vitro diagnostic device.

§ 892.1000 Magnetic resonance diagnostic device.

(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

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 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 II (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 (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic OS 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 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 (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. 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 (800) 638-2041 or (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrb/dsmaldsmamain.html".
