Innovative vascular screening for diabetes

The AngE uses the innovative TOPP method to provide a fast and secure diagnosis of the peripheral vessel status of diabetics, even with calcified vessels (media sclerosis). It allows measuring on ankle and wrists as well as on fingers and toes, including forefoot- and toe pressure measurement with TBI.

TOPP - Tissue Optical Perfusion Pressure

AngE TOPP combines four measuring cuffs and two optical sensors to enable the measurement on six measuring spots. This creates diverse possibilities to detect blood flow disorders within the final current areas as well as to assess the wound healing success of diabetic patients.

Simple Measuring Program in under 3 Minutes

The AngE TOPP measurement can be conducted easily by following a few steps and without significant stress for the patient. After applying the cuffs on ankles and wrists, as well as the optical sensors on the toes, the system applies a pressure of 180mmHg and decreases it stepwise by 10mmHg. By recording the optical sensors, the examiner can immediately determine the pressure step at which the patient’s toes show the first pulsations. Different key indicators like the ABI, the amplitude or the peak time of the pulse wave, are recorded simultaneously.

The high sensitivity of the optical sensors allow for a good documentation of the pulse waves, even with marginal blood flow. Given the virtually unfiltered display of pulse curves, dicrotic waves can be clearly identified for healthy and elastic arteries.
