The Accordion Piccolo URS is designed to slide easily past even impacted stones, form a patented film occlusion proximal to the stone, provide flexible placement, control retropulsion, and simplify the sweeping of small stones down the ureter without a guidewire.
Once in position, the occlusion film conforms to the shape of the ureter, unlike most other anti-retropulsion devices and baskets.
The occlusion film allows for normal levels of irrigation during stone fragmentation which can facilitate the rinsing of smaller fragments, keeping the field of view clear and shortening treatment times. The film has also been shown to reduce the intra-renal pressures inside the kidney.
In addition, it has been proven to be highly resistant to even multiple laser or shock wave lithotripsy ‘shots’ during therapy, which means that the Accordion URS’ functionality is not impaired – and can be deployed and undeployed anytime during therapy around the stones.¹
