Indications for Use

The BladderManager PCI 5000 and BladderScan BVI 5000 “project ultrasound energy through the lower abdomen of the non-pregnant patient to obtain an image of the bladder that is used to determine bladder volume non-invasively.”

Device Story

Portable, battery-powered ultrasound instruments; PCI 5000 for patient self-use; BVI 5000 for clinician use with docking cradle/printer. Devices project ultrasound energy through lower abdomen; capture pulsed echo signals; process data to calculate bladder volume. BVI 5000 provides hard copy printouts of images and volume. Used for intermittent monitoring of bladder volume. Output assists clinicians or patients in managing bladder function; non-invasive nature benefits patients by reducing need for catheterization.

Clinical Evidence

Clinical testing performed on adult ambulatory volunteers and patients with spinal cord disease at three independent sites. No significant adverse effects or complications reported. Results demonstrate safety and effectiveness equivalent to the predicate device.

Technological Characteristics

Pulsed echo ultrasonic imaging system. Battery-powered. Includes scanhead, transducer, and (for BVI 5000) docking cradle with printer. Differences from predicate include scanhead shape, patient contact materials, scan angle, ultrasonic coupling material, lateral resolution, acoustic output, and transducer model. Safety verified via acoustic output, thermal, mechanical, electrical, and biocompatibility testing.

Indications for Use

Indicated for non-invasive bladder volume measurement in non-pregnant patients, including adult ambulatory volunteers and patients with spinal cord disease.

Regulatory Classification

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.

# Device Description

The BladderManager PCI 5000 is a portable, battery-powered ultrasound instrument designed for a patient to non-invasively monitor his or her bladder volume on an intermittent basis. The BladderScan BVI 5000 is similar, except that it is designed for use by the clinician with the added feature of a “docking cradle” containing an onboard computer that provides a hard copy printout of the scan images and the bladder volume.

# Intended Use

The BladderManager PCI 5000 and BladderScan BVI 5000 “project ultrasound energy through the lower abdomen of the non-pregnant patient to obtain an image of the bladder that is used to determine bladder volume non-invasively.”

This statement of intended use is identical to that of the predicate device.

# Technological Characteristics Comparison

The BladderManager PCI 5000 and BladderScan BVI 5000 are substantially equivalent to the other currently marketed BladderScan BVI 2500 which is referenced above. The BladderManager PCI 5000 and BladderScan BVI 5000 and their predicate device are all pulsed echo ultrasonic imaging instruments dedicated to non-invasive measurement of urinary bladder volume. Although there are some technological differences between the BladderManager PCI 5000, the BladderScan BVI 5000, and their predicate device, these differences are minor and raise no new questions of safety and effectiveness. In addition, accepted scientific methods exist for assessing the effects of the technological differences. The BladderManager PCI 5000 and BladderScan BVI 5000 differ from the BladderScan BVI 2500 in scanhead shape, patient contact materials, scan angle, ultrasonic coupling material, lateral resolution, acoustic output, and transducer model number. However, accepted scientific methods for biocompatibility testing, ultrasonic acoustic output testing, and clinical testing demonstrated that the subject devices are substantially equivalent to the predicate device in terms of safety. Also, accepted scientific methods for clinical accuracy testing demonstrated that the subject devices are substantially equivalent to the predicate device in terms of effectiveness.

# Performance Data

Non-clinical testing included acoustic output testing, thermal, mechanical, and electrical safety testing, electromagnetic emissions and immunity testing, and biocompatibility testing. All non-clinical testing demonstrated that the subject devices are substantially equivalent to the predicate device in terms of safety, effectiveness, and performance.

Preliminary clinical testing of the BladderManager PCI 5000 and the BladderScan BVI 5000 was performed on adult ambulatory volunteers. No significant adverse effects or complications were noted. The results demonstrated that the device is substantially equivalent to the predicate device in terms of safety and effectiveness.

{2}

Clinical testing of the BladderManager PCI 5000 was performed at three independent clinical sites using adult spinal cord diseased patients, as well as healthy volunteers. No significant adverse effects or complications were noted. The results demonstrated that the device is substantially equivalent to the predicate device in terms of safety and effectiveness.

## Conclusion

Non-clinical and clinical testing methods demonstrate that the device is as safe, as effective, and performs as well as the legally marketed predicate device. The BladderManager PCI 5000 and the BladderScan BVI 5000 are substantially equivalent to the BladderScan BVI 2500 with respect to intended use, technological characteristics, and performance.
