The "4">'''time''' taken for Boston to get their stent Scientific'''approved''' ranged from '''21 days to 9 months''' ===Clinical trials===*The clinical trials of new medical devices of Class II and Class III can be conducted only after clinical trial approval by the relevant authority in accordance with the rules of the drug regulatory authority under State Council. '''Currently''' Boston scientific is conducting clinical '''trials''' for '''Truimph Ureteral stent''' which is a ureteral '''stent''' loaded with '''Triclosan''' (used as an antimicrobial agent).The trials are currently in '''Phase II''' in '''canada'''(NCT00250406).  *Other trials are related to comparison of various ureteral stent of different companies in terms of patient comfort and materials used in the stent.*The result of trials is that there is '''not much differenc'''e among the ureteral stents of different companies in terms of '''patient comfort''' and '''materials''' used in the stent ===Patents===*The '''mapped patents''' gives an insight in to patents which were '''successfully commercialized''' *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 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 has patents on various 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 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)font>|bgcolor ="#538ED5"|<font size =C.R.Bard== ===Products===* They have '''6 products''' in their ureteral stent portfolio* C.R Bard ureteral stent portfolio have some common features such as:#Most of the stent has '''Silicone''' as their '''main material'''#They have stent with '''various''' '''designs''' and shapes eg Figure "4 ureteral stent#Some of the stent have '''coatings''' which is '''liscensed''' from third party eg.">'''pHreecoat'''" ===Regulatory data===The time taken for C.R.
