TM-Flow System

TM-Flow System: Efficient In-Office Vascular & Autonomic Screening.

Healthwright Technologies offers the FDA-cleared TM-Flow system – a reliable and user-friendly device for independent physicians to conduct essential vascular (ABI), sudomotor function, and Heart Rate Variability (HRV) assessments.  

Reliable Screening for Your Independent Practice

The TM-Flow system, provided by Healthwright Technologies, is a non-invasive diagnostic device designed to give independent physicians valuable, foundational insights into their patients’ vascular and autonomic nervous system health. It efficiently integrates multiple testing capabilities – Ankle-Brachial Index (ABI) for PAD screening, sudomotor function assessment (related to small fiber neuropathy), and Heart Rate Variability (HRV) analysis for autonomic function – into one streamlined procedure. This offering focuses on providing the core TM-Flow device technology for practices seeking a dependable and efficient screening instrument.  

Key Features & Benefits of the TM-Flow System

Multi-Function Screening:

Efficiently assess ABI for Peripheral Arterial Disease (PAD) risk, sudomotor function for insights into small fiber neuropathy, and Heart Rate Variability (HRV) for an overview of autonomic balance – all with one device. 

Aid in Early Detection:

Provides valuable data that can help in the early identification of potential vascular and autonomic issues, allowing for timely patient management. 

Rapid & Efficient Testing:

Complete a TM-Flow assessment in approximately 7-12 minutes, making it ideal for busy independent practice environments and annual wellness visits. 

Non-Invasive & Patient-Friendly:

Ensures patient comfort with a gentle testing procedure, promoting acceptance of necessary screenings. 

User-Friendly Operation:

Designed for ease of use, allowing your existing clinic staff to perform tests with minimal training. 

Recognized Diagnostic Procedures:

TM-Flow testing is associated with established CPT codes (e.g., 95921, 93923, 95923). Coverage and reimbursement vary by payer and clinical indication. Providers should verify coverage independently. Coverage and reimbursement vary by payer. 

Core Technologies within the TM-Flow System

The TM-Flow system utilizes established technologies to gather its data: TBL-ABI for Ankle-Brachial Index measurement using oscillometric blood pressure cuffs; SweatC technology for assessing sudomotor function via galvanic skin response (GSR) using disposable electrodes; and OXI_W for photoplethysmography (PPG) analysis to determine Heart Rate Variability (HRV) and assess aspects of autonomic function. 

FDA-Cleared Indications for the TM-Flow System

(This needs to be precise based on the FDA 510(k) clearance for the specific TM-Flow model Healthwright Technologies distributes. It will likely cover ABI for PAD screening, sudomotor function assessment, and HRV analysis for autonomic function. Example phrasing, to be verified: “The TM-Flow System is intended for the non-invasive measurement of Ankle-Brachial Index (ABI) to aid in the assessment of peripheral arterial disease; the assessment of sudomotor function through galvanic skin response as an indicator of sympathetic autonomic function; and the analysis of Heart Rate Variability (HRV) to assess cardiovagal autonomic function in adult patients.”)
