Outline of Topics
Difference Between Tumour and Cancer
Novel Diagnostic Device
Wearable Device
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)
has initiated a survey globally and estimated that 1.5 million
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 lifethreatening 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.
Clinical Researchers have designed a device called cytophone which detects cancercausing 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.

blood vessels of a person's
hand to detect melanoma cells.
Novel Diagnostic 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-ona-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".

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.

a human
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.
