## Indications for Use

"Catalyst" is a diagnostic ultrasound system designed to be used for investigating disorders of the pelvic floor. An ultrasonographic crystal within the probe records images of the organ, muscle, and tissue structures of the pelvic region. MidCRYSTL and HALO probes allow for ultrasonography of the following: 1) on the surface of the perineum and/or abdomen, 2) endocavity, by inserting the endovaginal probe into the vagina, and 3) endocavity, by inserting the endoanal probe into the anal canal.

## Device Story

Portable, single-mode, single-application B-Mode ultrasound imaging system; utilizes mechanical sector ultrasound probes (3.5 MHz to 24.0 MHz). System includes ultrasound generator/receiver, analog-to-digital converter, microcontroller, and USB 2.0 interface. Operator inputs transmit power, image selection, and Time Gain Compensation (TGC) via control panel; system stores settings for recall. Device captures, displays, and records 2D ultrasound images; supports cine function (up to 512 images) and distance/angle measurements. Used in clinical settings for pelvic floor investigation; operated by healthcare professionals. Output viewed on LCD monitor; assists clinicians in visualizing organ, muscle, and tissue structures to inform diagnostic decisions.

## Clinical Evidence

Bench testing only. No clinical studies were required to support substantial equivalence. Compliance verified through acoustic output measurement (AIUM/NEMA UD-2/UD-3), electrical/ultrasound safety (IEC 60601-1, IEC 60601-2-37), EMC (IEC/EN 60601-1-2), and biocompatibility (ISO 10993-1, -5, -10, -12).

## Technological Characteristics

Mechanical sector ultrasound system; 3.5-24.0 MHz probes. Materials: TPX (Polymethyl Pentene) lens, Ertalyte (PET-P) housing. Energy: Piezo-electric transducer. Connectivity: USB 2.0 to host computer. Display: 2D, 256 gray shades. Features: Digital dynamic receive focusing, cine storage (512 images), distance/angle measurement. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-37, ISO 10993.

## Regulatory Identification

An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Special Controls

*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system 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 Mr. Job:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

This determination of substantial equivalence applies to the following transducers intended for use with the Halo Medical Technologies Catalyst™, HALO™ Ultrasound System, as described in your premarket notification:

Transducer Model Number

ER/12 MHz/ES 12MHz

GP 3.5 MHz/AB 3.5 MHz. EC 7.5 MHz/EB 7.5 MHz

If your device is classified (see above) into either class II (Special Controls) or class !!! (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Paris 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
