On the basis of modalities, microarrays market can be segmented into DNA, tissue, protein, low complexity and carbohydrate. DNA microarrays market is the largest segment in the microarrays market. types of DNA microarray include glass cDNA microarrays and in situIn situ oligonucleotide array format. Some of the advantages of cDNA microarray include lower cost and no need of specialized equipment for hybridisation. On the basis of application, microarray market can be segmented into gene expression, drug discovery, screening and monitoring of patient data, genetics, cancer diagnostics and treatments, single nucleotide polymorphism (SNP) analysis, agricultural biology, environmental control, proteomics, toxicogenomics and microbial genotyping. On the basis of type, DNA microarrays market can be segmented into oligonucleotide DNA microarrays (oDNA) and complementary DNA microarrays (cDNA). DNA microarray is required for unhindered binding, no cross contamination, firm tethering and using larger and DNA molecules. Some of the DNA microarray development trends include glass arrays trends, agilent technology, amersham's coating technology and probe technology.

Prosthetic heart valve refers to a surgical implant that is used to replace an abnormal heart valve from an artificial heart valve. Prosthetic heart valves reduce the morbidity and mortality associated with cardiac valve disorders. Technological advancement and increasing prevalence of heart valve diseases are some of the main factors that are driving the prosthetic heart valves market. On the basis of product type, prosthetic heart valves market can be segmented into mechanical heart valves, transcatheter heart valves and tissue heart valves or bio-prosthetic valves. Tissue heart valves can be further segmented into stented tissue valve, stentless tissue valve, tissue- engineered valves and homograft and heterograft valves. Mechanical heart valves include aortic valve replacements and mechanical mitral valve replacements. Tissue heart valves include tissue aortic valve replacements and tissue mitral valve replacements. Tissue heart valve is the fastest growing segment in the prosthetic heart valves market. Some types of heart valve disorders are valvular stenosis, valvular regurgitation. Condition associated with heart valve disorders are congenital defects and acquired disorders. Some of the technologies for prosthetic heart valves are transcatheter valves, anti-calcification technology, suture-less valves, polymers and carbon-based technologies. Mechanical heart valves are used in percutaneous implantation and thoracotomy implantation. Tissue heart valves are used in homografts and heterografts. Non-invasive heart valves are used in exchangeable heart valve and expandable heart valve.

Peripheral intravenous (I.V.) catheters refer to the medical devices that are used to deliver the medication or fluids directly into the vein of a patient. Peripheral I.V. catheter is inserted into the body with the help of needle which is removed after insertion of catheter. Peripheral I.V. catheter is then fixed onto patient's skin with the help of an adhesive tape. Peripheral I.V. catheters market is growing at a significant rate due to increase in the number of patients suffering from infections and other diseases. On the basis of their types, peripheral I.V. catheters can be classified into central catheters and midline peripheral catheter. On the basis of their insertion mode, central catheters can be classified into centrally inserted central catheters and peripherally inserted central catheters.

Syringes and needles are sterile devices used to inject solutions into the body. Syringes and needles are also used to isolate various types of body fluids, such as tissues from swollen joints and blood from veins. A syringe is made up of glass or plastic and shaped like a cylinder with a plunger at one end and an opening that attaches to a needle. Needles are hollow metal tube with a pointed tip.

Neurosurgery or neurological surgery is the medical area of expertise which is specialized in the diagnosis and treatment of the spinal cord, brain and peripheral nerves disorders. Some of the major disorders, such as aneurysms, hydrocephalus, arteriovenous malformations (AVMs) and pituitary and intracranial tumors, require neurosurgery for their treatment. These surgeries are carried out by specific neurosurgical products. For instance, hydrocephalus is characterized by the abnormal accumulation of cerebrospinal fluid in the brain is treated by using aIntracranial shunts. Similarly, aneurysm, weakness in the wall of blood vessel of the brain, is treated by using surgical clips. AVM is characterized by abnormal connection between artery and vein is also treated by surgical clips.

Huber needles are hollow needles that have slant tips to make it easy to go through the skin. Huber needles are used in chemotherapy, drug delivery, transfusions and blood samplings through the implanted port septum which is surgically rooted into the skin. They come in several sizes to fit the patient. With a Huber needle, the patient does not have to endure multiple needle sticks. They also protect clinicians from needle stick injuries.

The term "immunoglobulin" refers to the breakdown of blood plasma that contains antibody. IVIg is a blood product which is administered intravenously. It contains polyvalent IgG antibodies which are extracted from the plasma of more than thousand of blood donors. Individuals who are unable to produce adequate amount of antibodies, such as patients with common variable immunodeficiency, Wiskott Aldrich Syndrome, X-linked agammaglobulinemia and other forms of hypogammaglobulinemia, get benefit from IVIg to maintain the appropriate level of antibodies in the body.

Iron is one of the most important mineral present inside the human body. It carries oxygen throughout the body via blood, which is further utilized by cells and tissue to get energy for all vital biological processes. Moreover, deficiency of iron leads to severe health problems, such as anemia and also affects mental or other memory functions in youths. To overcome this problem, oral iron supplements are recommended to maintain iron level in the body. However, in some cases, oral administrations are not capable to maintain the iron level in the body. For these cases, IV iron therapy is used to as part of which iron is directly injected inside the body with a needle through a vein.

A medical image enables doctors to view the current situation of the patient's medical conditions. Medical images are used for the visualization of the organs, body parts and tissues and facilitate physicians to diagnose and treat diseases. Various medical imaging techniques are used to visualize organs and tissues at their cellular level. Major imaging techniques include nuclear imaging, optical imaging and radiology. These imaging technologies are specialized in different therapeutic areas. For instance, the radiological method of image capturing is specialized in anatomical and physiological visualization of the human body. In addition, advancement in medical imaging devices makes image capturing technologies more easy and convenient to image viewers. For instance, optical coherence tomography (OCT) is used in optical imaging techniques which helps in visualization of abnormalities at cellular level.
