DEVICE: STONE CENTER SILHOUETTE (30607915123759)

A sterile non-bioabsorbable tubular device intended to be implanted in an obstructed ureter (e.g., from stone, stricture, compression, fibrosis, trauma) to maintain luminal patency allowing urine to drain from the renal pelvis to the bladder. It is made of a synthetic polymer(s) [e.g., polytetrafluoroethylene (PTFE), polyethylene (PE), silicone], sometimes with a hydrophilic coating (e.g., hydrogel), and may have various designs (e.g., continuous tube with or without drainage side holes, covered or non-covered mesh structure). Disposable devices intended to assist implantation may be included. The device is typically intended for long-term, but not permanent, implantation.

A metal coil or wire intended to assist the insertion/positioning of a diagnostic/therapeutic device(s) [e.g., endoscope, catheter] within the gastrointestinal (GI) and/or urinary tract. It is typically coated with a plastic material [e.g., polytetrafluoroethylene (PTFE), commonly known as Teflon, or polyethylene (PE)]. It may have radiopaque graduated markings at the distal end to assist in the fluoroscopic monitoring of its advancement/position within the body. This is a single-use device.
