/* Patents */
*The '''unmapped patents''' gives us a glimpse of '''future moves''' in terms of product development strategy.It may also '''signify''' those patents which '''failed to productize'''.
*The unmapped patents are analysed based on the following parameters
'''1.Coating on stents:''' Boston scientific have has patents on Therapeutic/ medicinal coatings on stents which releases into the vascular region. Magnetic nanoparticles which helps in imaging the ureteral stent using MRI. Lubricious coatings which help in easy insertion of the stent
'''2.Structure of stent:''' Boston scientific have has patents on various structure structures of stent . For eg : Multiple channels(Depressions) along the length of stent filled with therapeutic agent,Multiple segments on the distal side of stent which is collapsible to prevent fluid from passing from the bladder to the kidney.,Stent with a renal coil with wick portion to prevent reflux of urine,Stent with beads on its surface which is of figure 8 shape having therapeutic agents,Stent with reservoir indicating its release with change in color of urine,Stents with degradable barbs,Expandable and collapsible stent to reduce patient discomfort
'''3.Materials used for stent:'''Boston scientific have has patents on various materials used for stent. For eg.Elastically deformable stents(polysaccharide-based hydrogels), Biodegradable polymer based stents, Porous polymer for long term implantation( poly(styrene) blocks and polyisobutylene blocks),Stent with variable hardness (ethylene vinyl acetate and hydroxypropylcellulose)
