Artificial Vascular Grafts
Vascular diseases are characterised by variations to the geometry and structure of the walls of the
blood vessels. Variations in the mechanical characteristics of the vessels result in multiple
complications like Thrombosis, Aneurysm and Arteriosclerosis.
Product characteristics
In order to function effectively, the grafts need to have special characteristics like – non-thrombogenic
surface, elasticity and compliance, long-term tensile strength, bio-compatability, durability, bacteria
resistance, etc. The type of fabric used for prostheses is woven fabric or knitted fabric. The knitted
fabric is easy to suture and well suited for aortic replacement however not for large diameter vessels.
The knitted fabric is porous and needs to be clotted with patient’s blood before usage. On the other
hand, the woven fabric has the strongest construction but is difficult to suture. Most textile grafts for
large and medium artery replacement are made of either PET (polyethylene terephthalate, commercial
name Dacron) or PTFE (polytetrafluoro ethylene, commercial name Teflon).
Market size of vascular graft and future forecast
The vascular graft market in India is quite small and the requirement is primarily met through imports.
The current usage of grafts is annually around 5,000 units. The price range varies from as low as Rs.
2000 to Rs. 20,000. The average price is around Rs 9,000 per graft. The industry is expected to grow
at around 10% y-o-y.
The vascular graft is a 100% technical textile product produced by warp knitting process.

The potential market for vascular graft industry in 2012-13 is estimated at Rs. 7.2 crore up from Rs.
4.5 crore in 2007-08 (E). In volume terms, the vascular graft industry is expected to grow from 5,000
nos. in 2007-08 to 8,000 nos. in 2012-13. No inflationary increase has been assumed for the price of
these products as the prices have fallen over the years.
