In medical terms, a stent is a plastic or a meta tube penetrated into the lumen of an anatomic vessel or duct to keep the passageway open. Stenting is the placement of a stent and there are various ways to insert it. A variety of stents are used for different purpose from expandable coronary, biliary and vascular stents to simple plastic stents to allow the flow of urine between kidney and bladder. Coronary stents and vascular stents are the types of stents. In coronary stents, stenting is carried in coronary arteries (a bio absorbable stent) or a dual-therapy stent. In vascular stents, stenting is carried in peripheral arteries namely peripheral arteries angioplasty. On the other hand, a gel stent is a type of hydrophilic tube comprising porcine gelatin cross-linked with glutaraldehyde.

The stent is a rigid tube, which
softens upon hydration. Implantation is identical for all models and due to its
flexibility, the implant conforms to the tissue and there are minimum chances
of migration and erosion. The surgical technique for implanting gel stent is to
insert across the anterior chamber into the quadrant of the eye where
implantation is planned. The small incision approach to glaucoma surgery is
known as micro invasive glaucoma surgery.
Commercially, population above 40
is more vulnerable to eye diseases and non-functioning of eye structures.
Glaucoma being the leading cause for blindness is solely responsible for eye
surgeries. Therefore, the most common surgical treatment for glaucoma is
trabeculectomy and trabeculoplasty, which are highly effective, though
invasive. The key driving factors responsible for the growth of gel stents
market includes rising demand for dissolvable stents. Growing geriatric
population and high prevalence of coronary disease and heart failure are adding
to the growth of the stent market.
Additionally, presence of big
players adopting innovative technologies and increasing advances in the domain
of interventional cardiology interlinked with minimally invasive techniques is
contributing to the market growth. Moreover, constant advancements in healthcare
insurance and reimbursement are anticipated to boost the market growth in
developed and developing countries. However, the higher costs associated with
the stents in emerging countries is likely to impede the growth of the market.
