The device is a physical standoff made of silicone or urethane elastomers designed to physically elevate the ultrasound transducer. The description focuses on the material properties and physical design, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No.
The device is described as an accessory for diagnostic ultrasound, specifically designed to improve visualization of near-field and superficial structures by controlling the distance between the transducer and body surfaces for optimal focusing. It does not exert any direct therapeutic effect on the patient.
No.
The device is an accessory that improves the visualization of near-field and superficial structures during diagnostic ultrasound procedures, but it does not perform diagnosis itself.
No
The device is a physical accessory made of silicone or urethane elastomers that is placed on an ultrasound transducer. It is described as having mechanical properties and being evaluated using a phantom, indicating it is a hardware component.
Based on the provided information, 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 Ultrasound Transducer Standoff is a physical accessory used with an ultrasound transducer. Its purpose is to adjust the distance between the transducer and the body surface to improve image quality during diagnostic ultrasound procedures. It does not analyze biological samples.
- Intended Use: The intended use clearly states it's for "diagnostic ultrasound" and "scanning and needle guided procedures for body surface and endocavity diagnostic ultrasound." This describes a medical imaging procedure performed directly on the patient, not an in vitro test.
The device is a medical device used in conjunction with diagnostic ultrasound equipment, but it does not fit the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Ultrasound Transducer Standoff is placed over a diagnostic ultrasound transducer / probe / scanhead to control the distance (offset) between transducer and body surfaces for optimal focusing by shifting the transducer, effectively offsetting the focal zone, for improved visualization of near-field and superficial structures. The transducer standoff device can be used to perform scanning and needle guided procedures for body surface and endocavity diagnostic uttrasound. Standoff devices are furnished as a non-sterile; single use patient / procedure, with limited reuse capability (as designated in instructions for use) if properly cleaned / disinfected between patient uses.
The intended use and indications for use place Ultrasound Transducer Standoffs in device body contact categories as follows:
a) surface devices, intact skin / mucosal membranes / breached surfaces, limited contact duration (

Identification. A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.(b)

B. Device Description
The Ultrasound Transducer Standoff device provides a firm, conformal fit to the ultrasound transducer that elevates the transducer from the body surface for near-field imaging. The standoff device provides a fixed height to which the sound transmits through allowing the focal zone of the transducer to be repositioned on near field tissue. Standoff materials are silicone or urethane elastomers. The standoff device material's purpose is to provide a media to offset the transducer from the body surface to be scanned, thereby, shifting the focal zone of the transducer, while still providing a media through which the user can obtain an acceptable image visualization of near-field and superficial structures. Transmission of the sound through the standoff material should not introduce a large amount, if any, of distortion and artifacts, nor absorb a great deal of sound.
Standoff devices are custom designed to each, specific ultrasound transducer geometry and scanning depth needs. Product categories / models include:

Configurations of Ultrasound Transducer Standoffs
Image /page/1/Picture/5 description: The image contains two 3D renderings of geometric shapes. Both shapes appear to be trapezoidal prisms, with one positioned on the left and the other on the right side of the image. The shapes are rendered in grayscale, with variations in shading that suggest a light source illuminating them from above.
Figure A
Self-bracketing wedge configuration is solid silicone or urethane material, or may be solid material encapsulating an inner silicone gel material depending on design requirements and specifications.
Image /page/1/Picture/8 description: The image is a black and white photograph of an object. The object is dark and has a rounded shape. There are two small white dots on the object. The background is white.
Image /page/1/Picture/9 description: The image is a black and white photograph of a dark, irregularly shaped object. The object appears to be solid and opaque, with a smooth surface. There is a curved, lighter-colored streak running across the surface of the object, possibly a reflection or a scratch. The background is plain white, which helps to isolate the object and emphasize its shape and texture.
Figure B
Self-bracketing flat configuration is solid silicone or urethane material, or may be solid material encapsulating an inner silicone gel material depending on design requirements and specifications.

Image /page/2/Picture/0 description: The image shows two separate diagrams of a small, dark-colored object. The object on the left is a wedge shape, with a small slit on the side. The object on the right is a larger, more complex shape, with a similar wedge shape next to it. The larger object has a series of ridges on top.
Figure C
Wedge configuration for inserting into biopsy bracket is solid silicone or urethane material, or may be solid material encapsulating an inner silicone gel material depending on design requirements and specifications. Standoff is captured inside the bracket. An advantage to this design is the reduced risk of puncturing the standoff during a needle biopsy procedure.
Image /page/2/Picture/3 description: The image shows two capsules on a white background. The capsule on the left has two rings around the bottom. The capsule on the right is smooth.
Image /page/2/Figure/4 description: The image shows the text "Figure D". The text is in a sans-serif font and is black. The background is white.
Endocavity standoff is solid silicone material, or may be solid silicone material encapsulating an inner silicone gel material depending on design requirements and specifications.
Standoffs are installed against the face of the transducer with a small amount of gel at the interface to provide adequate ultrasonic coupling. Instructions for use include the recommendation for always using a transducer cover in endocavity and/or needle puncture procedures.

Standoff devices have limited reuse capability (# of reuses per instructions for use) if properly cleaned / disinfected. The level of disinfection or sterilization should be appropriate for the intended clinical use. Reprocessing of the standoff device is required between single patient uses and can be accomplished using the following validated methods - cleaning with enzymatic detergent & water; disinfection / sterilization by 2% glutaraldehyde based solution; sterilization of solid one-piece (silicone only) standoffs can be accomplished by steam autoclaving.
Standoff devices are packaged in a non-sterile "procedure kit" form. Standoff devices are furnished separately and in procedure kits supplied with transducer covers, and with or without coupling gel packet. Standoff devices are also combined with needle guide devices into custom kits that CIVCO builds for ultrasound OEMs and end users.
