Indications for Use

Dopplex Ability is indicated for use on adult subjects at risk of having or developing peripheral arterial disease (PAD). Dopplex Ability is intended for rapid measurement of ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) in adults and pulse volume recording (PVR) / volume plethysmography. It is suitable for use in woundcare assessment, for assessing symptomatic PAD, and as a screening device for PAD. It may also be used on patients with venous or arterial ulcers prior to the application of compression therapy. Dopplex Ability can be used on patients with unilateral lower limb amputation.

Device Story

Dopplex Ability is an automated diagnostic device for measuring Ankle Brachial Index (ABI) and Pulse Volume Recording (PVR). The operator applies four color-coded cuffs to the patient's limbs; the device automatically controls inflation/deflation and monitors minute pressure variations to calculate ABI and record PVR waveforms. The test is performed as a single occurrence, taking approximately 3 minutes. Results are displayed on an LCD and can be printed. Used in clinical settings for PAD screening and woundcare assessment; provides objective data to assist clinicians in diagnosing vascular disease and determining suitability for compression therapy. Benefits include rapid, simultaneous four-limb measurement, eliminating the need for patient rest between limb assessments.

Clinical Evidence

Clinical data and bench testing were submitted comparing the Dopplex Ability to the predicate device. The study evaluated the capability of both devices to measure ABI indices. Results demonstrated that the subject device performs as well as the legally marketed predicate device in measuring physiological parameters for ABI calculation.

Technological Characteristics

Pneumo-plethysmography sensing principle; four-limb cuff system; AC powered with optional battery and integral printer; LCD display; in-house algorithm for ABI calculation. Class II device.

Indications for Use

Indicated for adult patients at risk of or with peripheral arterial disease (PAD), including those requiring woundcare assessment, screening for PAD, or assessment prior to compression therapy for venous/arterial ulcers. Suitable for patients with unilateral lower limb amputation.

Regulatory Classification

Identification

device to provide the performance as indicated for use by a comparison of measured indices using both devices. This supports the demonstration of its safety and effectiveness.

#### Description :

Dopplex Ability is intended to measure a patient's Ankle Brachial Index (ABI) and provide PVR. This is done through an automated process.

The operator places the four colour coded cuffs on each of the patient's limbs as described in the instruction for use and connect to the device.

When connected the operator pushes soft touch button to start measurement, the device then will automatically control the inflation / deflation of the cuffs on each limb and monitor minute variations in individual pressures to determine values to be used for the calculation of the ABI values for both the left and right hand of the patient.

Dopplex Ability uses pneumo-plethysmography uses obtain physiological measurements from patient's limbs. Measurements are conducted as a single occurrence on all four limbs, eliminating any requirement to rest the patient between measurements.

The test period takes approximately 3 minutes. The ABI indices are calculated using an in house algorithm.

ABI values are displayed on the LCD and can also be printed. In addition, records are generated of the Pulse Volume Waveforms (PVR), which may also be displayed on the LCD and can be printed.

Substantial Equivalence:

Dopplex Ability is substantially equivalent to the cleared device: Vascular Assist (K002186), cleared 05/02/2001

Technologies Summary:

The predicate device utilises Doppler technology to measure physiological parameters used in calculating into ABI indices. Whereas Dopplex Ability uses pneumo-plethysmography to obtain physiological parameters from patient's limbs

The predicate device has been used in comparison bench testing and clinical assessment to evaluate and demonstrate the equal capability of both devices to measure ABI.

Conclusion:

The non clinical and clinical data detailed within submission demonstrates that the device is safe and effective and performs as well as the legally marketed Predicate device, identified in this summary. With respect to Dopplex Ability to function to measure all four limbs as a single occurrence, the submission device provides improved functionality above that of the legally marketed predicate device without addition concerns regarding safety and effectiveness.
