Intended Use
The ABPI MD system is indicated for use on adult subjects at risk of having or developing peripheral arterial disease (PAD). The ABPI MD system is intended for the rapid measurement of ankle-brachial pressure index (ABPI), or ankle-brachial index (ABI) and pulse volume recording (PVR)/volume plethysmography in adults. It is suitable for use in wound care 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 application of compression therapy. ABPI MD system can be used on patients with unilateral lower limb amputation. The ABPI MD system is intended to be used to spot-check patients. The ABPI MD system provides information regarding patient risk. The physician has the responsibility of making proper judgments based on this information. Prescription Use: Federal law restricts the use of this device to sale by or on the order of a physician.
Device Description
The ABPI MD system, is an automated ankle brachial pressure index measuring device, the system includes the following components: - -ABPI measuring unit - -Arm cuff size M - -Left ankle cuff size M - -Right ankle cuff size M - -AC/DC power supply - Tubes - - -USB cable - -Instructions for use, Installation and User guide, Certificate of Calibration, Certificate of Conformity and Warranty - Software installed on a computer - It is intended to measure a patient's Ankle Brachial Pressure Index (ABPI) and Ankle Brachial Index (ABI) and provides Pulse Volume Recording (PVR) / volume plethysmography. This is done through an automated process. The operator places the three color coded cuffs on the right or left arm, and on each ankle as described in the instructions for use, and connects to the device. When connected, the operator clicks start button to begin measurement. The device will then automatically control the inflation of the cuffs and monitor variations in individual pressures to determine values to be used for the calculation of the ABI values for the both left and right of the patient.

No
The summary describes an automated system for measuring ABPI and PVR using cuffs and pressure variations. There is no mention of AI, ML, or any related technologies in the device description, intended use, or performance studies. The software mentioned appears to be for controlling the automated process and calculating standard physiological indices, not for complex pattern recognition or learning.

No.
The device is intended for diagnosis and screening of PAD by measuring ABPI/ABI and PVR, not for direct treatment of a disease or condition.

Yes

The device is intended for the "rapid measurement of ankle-brachial pressure index (ABPI), or ankle-brachial index (ABI) and pulse volume recording (PVR)/volume plethysmography in adults." It is used for "wound care assessment, for assessing symptomatic PAD, and as a screening device for PAD," all of which are diagnostic purposes. The statement "The ABPI MD system provides information regarding patient risk" further supports its role in diagnostics.

No

The device description explicitly lists multiple hardware components including a measuring unit, cuffs, power supply, tubes, and a USB cable, in addition to software.

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 ABPI MD system measures physiological parameters (blood pressure and pulse volume) directly from the patient's body using cuffs. It does not analyze samples taken from the body.
  • Intended Use: The intended use describes the measurement of ABPI/ABI and PVR/volume plethysmography, which are physical measurements, not laboratory tests on biological samples.
  • Device Description: The description details the components and process of applying cuffs and measuring pressure and volume, which aligns with a non-IVD medical device.

Therefore, the ABPI MD system is a medical device used for physiological measurements, not an in vitro diagnostic device.

SUMMARY of TESTING:

The same testing and validation performed to qualify the TM-ABI is the testing for the ABPI MD, which includes:

Biocompatibility testing was performed in accordance to ISO 10993-1 "Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing.'

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices."

Electrical Standard tests were performed to evaluate its electromagnetic compatibility (EMC). Device was tested according to standards IEC 60601-1-2:2007 Medical Electrical Equipment - Part 1: General Requirements for Safety: Electromagnetic Compatibility -Requirements and Test.

CONCLUSION:

The ABPI MD by MESI, Ltd. is identical to the predicate device. The ABPI MD device has the same indication for use, intended use as the TM-ABI predicate device, the same materials and technology as the predicate device, and utilizes the same manufacturing processes as the predicate device. The same test results apply to both devices, because MESI, d.o.o. is Original Equipment Manufacturer (OEM) of the predicate device (TM-ABI system) and manufacturer of the ABPI MD. The only difference between the TM-ABI predicate device and ABPI MD device is labeling of the device and distributor's name and logo.
