A polyurethane ureteral stent, radiopaque along its length and graduated, placed over a guidewire for internal splinting of the ureter.
A ureteral stent is a double pigtail tube placed in the ureter. It is used for disorders of urine flow in the ureter from a stricture, a stone or a carcinoma; after ureteroscopy while the ureter settles; as prophylaxis during extracorporeal shock wave lithotripsy; and in retroperitoneal fibrosis and after a perforation or an avulsion. The physician decides on the indication.
How long the stent stays in depends on the patient and the case, and the treating urologist decides it, together with when it is removed or exchanged. The manufacturer describes the material of HEPARIUS as suitable for long-term indwelling use, and the instructions for use of the product apply.
The REF 4145 family has a monofilament application thread. It is a placement aid: the thread is removed immediately after the stent is placed, so it does not stay in the patient.
Charriere 4.8, 6.0 and 7.0, at 24, 26, 28 and 30 cm. Charrière (Ch) is the same scale as French (Fr): 1 Ch is a third of a millimetre of outer diameter, so Ch 4.8 is about 1.6 mm, Ch 6.0 about 2.0 mm and Ch 7.0 about 2.3 mm. The 23 models sit in three families: with an application thread, as a pre-assembled set with a guidewire, and not perforated. The physician chooses the size.
0.028 inch for the Ch 4.8 stent, 0.035 inch for Ch 6.0 and Ch 7.0.
There is no coating. The material is polyurethane with an additive that the manufacturer describes as reducing encrustation and bacterial adhesion; the body is radiopaque along its length and graduated. HEPARIUS is the name of the range.
The price depends on the model (size, length and family) and the quantity. We do not publish a list price on this page. Write to us and we will prepare a quote.
Yes, as a pre-assembled set. The REF 4155 to 4157 family is a pre-assembled set with a PTFE coated guidewire, and for Ch 6.0 and Ch 7.0 it carries a 45 cm pusher system. For the Ch 4.8 stent the pusher is 45 cm or 70 cm. The guidewire is 0.028 inch for Ch 4.8 and 0.035 inch for Ch 6.0 and Ch 7.0.
