The Intercept™ Internal MR Coils are recommended for high-resolution Magnetic Resonance Imaging of internal anatomical structures. The single use, disposable coils were designed to be inserted into body orifices of the patient during MRI scans in order to obtain improved image quality in the anatomical regions surrounding the coil. The unique coil shapes facilitate orientation of the coils to the anatomy. These products are to be used with a 1.5T MRI machine.
The Intercept™ Esophageal Internal MR Coil is recommended for high-resolution Magnetic Resonance Imaging of the human esophaqus. The single use, disposable coil is designed for insertion into the esophagus of the patient during MRI scans in order to obtain improved image quality in the anatomical regions surrounding the esophagus. The unique coil shape facilitates orientation of the coil to the anatomy. This product is to be used with Siemens 1.5T MRI systems.
The Intercept™ Urethral Internal MR Coil is recommended for high-resolution Magnetic Resonance Imaging of the male and female urethra and surrounding tissue. The single use, disposable coil was designed to be inserted in the urethra of a patient during MRI scans in order to obtain improved image quality in the anatomical regions surrounding the urethra and including the prostate in males. The flexible coil facilitates placement of the coil in the anatomy. This product is to be used with Siemens 1.5T MRI systems. The signals picked up by the coil are conducted through a small coaxial cable to a connection with the standard surface coil connector for MRI systems. The coil and cable are completely sealed inside the insulating layer.
The Intercept™ Vascular Internal MR Coil is recommended for high-resolution Magnetic Resonance Imaging of the peripheral vasculature. The single use, disposable coil is designed for insertion into an artery or vein of a patient during MRI scans in order to obtain improved image quality in the peripheral vasculature. The flexible coil facilitates placement of the coil in the peripheral vascular anatomy. The coil would most commonly be used through femoral artery access similar to .035" guidewires currently in use. The handling characteristics of this device are familiar to vascular interventionalists thereby facilitating integration into their practices. This product is to be used with Siemens 1.5T MRI systems.
The Intercept™ Internal MR Coils are intracavitary specialty coils for use in MR imaging of the anatomical regions surrounding a body cavity. The signals picked up by the coil are conducted through a small coaxial cable and interfacing network to a connection with the standard surface coil connector for MRI systems. The coil is insulated with polymeric housing that protects is from contact from body fluids.
The provided document is a 510(k) summary for the Intercept™ Esophageal, Urethral, and Vascular Internal MR Coils. It focuses on demonstrating substantial equivalence to previously cleared predicate devices for use with Siemens 1.5T MRI systems. This type of submission generally emphasizes safety and functional equivalence rather than extensive clinical comparative effectiveness studies found in other regulatory pathways.
Therefore, the information typically requested in your prompt regarding acceptance criteria for clinical performance, sample sizes for test/training sets, expert qualifications, and MRMC studies is not extensively detailed. The performance data presented primarily addresses safety and a qualitative assessment of imaging performance.
Here's an attempt to extract and describe the information based on the provided text:

§ 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.
