Device  Conclusion
Medical devices are effective tools to screen, diagnosis,  
provide treatment or to manage the disease or illness when 
 it can't be cured.
Initially, in 2008, the World Health Organization (WHO)  
Introductio has initiated a survey globally and estimated that 1.5 million 
n  medical devices exist, in more than 10,000 types of 
generic  device groups.
The significant demand for the use of appropriate medical 
 devices is to diagnose mainly the tumours to manage 
the  clinical interventions.
Difference Between Tumour and 
Cancer
Clinicians systematic review better understand the difference between tumours and 
 cancers, where tumours are considered as a mass of cells and cancers are the 
life-  threatening tumours.
It becomes essential to use efficient medical devices to capture the circulating tumour 
 cells in the bloodstream to provide potential evidence for early detection of cancer.
A novel,sophisticated technology of medical devices has been introduced to detect 
 the tumour cells through a noninvasive procedure.
Cytophon
e
Clinical Researchers have designed a device called cytophone which detects cancer- 
 causing cells inside the patient's body.
This device shots the laser pulses on the blood vessels of a person's hand that is fixed 
 in a customized holder.
When the laser beams catch the passing through melanoma cells, it heats the pigment 
 inside and produces sound waves that are detectable by an ultrasound transducer.
This device can detect circulating tumours in skin cancer patients and also detects 
 small blood clots.

device  shots the laser 
pulses on the  blood 
vessels of a person's  hand 
to detect melanoma cells.
NovelDiagnostic 
Device
A novel device which is ultrasensitive is used to detect mainly ovarian cancer  
even in the minimum amount of plasma or in patient's blood droplet is the lab-on- 
 a-chip.
In this scientific research technique, it combines and senses with the biological  
elements depending on the herringbone pattern, and pushes the exosomes in  
contact with the chip's which is more efficiently sensing surface and this process 
 is known as"mass transfer".

detect cancer  from a blood or plasma droplet.
Wearable 
Device
Another device developed by Michigan engineers and doctors was a wearable  
device,which could accurately diagnose and treat cancer more effectively.
This device was experimented on animals initially, and observed circulating tumour  
cells in the blood and was captured to eliminate tumour cells permanently.
Further, scientific analysis in the process of development, the gadget that filters the  
blood was used to diagnose and later used to treat metastatic cancer in humans.

Conclusio
n
These devices bring out early and effective detection of disease with the
noninvasive process.
Its potential evaluation might provide accurate information to doctors to treat their 
 patients at the initial stage.
As the diagnosis through medical devices is comparatively cheaper, easier and 
 reliable to producean accurate diagnosis, further scientists would expand the  
applications of the medical devices in detecting other various diseases.
