Last week, Numerex Corp, a provider of machine-to-machine (M2M) products and services, announced the development of a complete Device-Network-Application (DNA) service for remote cellular monitoring of HeartAssist5 System, a heart pump monitoring technology.
MicroMed Cardiovascular Inc.’s HeartAssist5 is a system consisting of two devices: a Left Ventricular Assist Device (LVAD) and a Controller. The MicroMed HeartAssist5 LVAD was originally developed by a heart surgeon in partnership with NASA. It is the only LVAD with a precise, direct flow measurement system and cellular-based remote monitoring, according to Numerex (Atlanta, Ga., USA).
According to MicoMed (Houston, Texas, USA), this information is useful when a patient is stable, but is vital if a patient is experiencing complications. Other LVADs rely on estimates by their software or provide no flow data at all.
Numerex developed the wireless monitoring connectivity and software application for the HeartAssist5System. Prior to Numerex implementing the new M2M technology, clinicians accessed device data after the body-worn external controller unit was physically plugged into the MicroMed Heart Attendant and transmitted via a local internet connection. This limited mobility and continuous reporting could not occur, says Numerex.
The MicroMed Cardiovascular team sought a solution to improve real-time visibility to the devices and engaged Numerex to integrate a cellular radio into the MicroMed Controller, provide cellular network services, and deliver a web-based application to consolidate and present the reported data for clinicians to review.
The MicroMed Cardiovascular M2M application was built using the Numerex FAST platform. As part of the Numerex DNA solution, the firmware was optimized to reduce the size of the data packet transmissions, ultimately optimizing from over 50MB to less than 4MB per month and resulting in cost savings. Remote monitoring of the device is now continuous and consistent, allowing for relevant device statistics to be reported around the clock. More importantly, any anomalies in the device are reported in real-time, says the company.
