Non-vascular guide wire is disposable sterile interventional consumable specially applied for endoscopic minimally invasive dilation and drainage operations in digestive tract, biliary tract and urinary system. It is split into two independent product lines: Zebra straight-tip guide wire and Super hard J-tip elbow guide wire. All specifications adopt high-strength nickel-titanium anti-torsion inner core plus integral PTFE smooth outer coating to guarantee stable passing inside tortuous narrow lumen.
Zebra series features unique two-color alternating interphase coating, the alternating color mark helps surgeons observe wire advancing position directly under endoscope; its tapered gradual reduced tip enhances tip flexibility to smoothly cross stricture. Superhard series owns fixed J-shaped elbow tip with excellent shape retention, not easy to bend or deform during repeated straightening. Complete size range covers five diameters from 0.021" to 0.038", length from 45cm up to 260cm to satisfy diversified clinical lumen access requirements. All wires are EO sterilized for single clinical disposable use.
First, nickel-titanium anti-torsion core provides outstanding torsion resistance and high bending strength, avoiding wire kink or breakage when passing curved narrow duct and drastically reducing operation failure risk. Full PTFE coating minimizes friction coefficient to realize low-resistance smooth propulsion inside human lumen.
Secondly, differentiated structural design realizes targeted clinical matching: zebra straight tip is ideal for preliminary crossing of irregular stricture with unknown lumen shape relying on flexible tapered tip; fixed J-shaped superhard wire is perfect for cannulation of orifice such as bile duct papilla, the non-deformable elbow keeps stable orifice positioning after repeated shaping. Diversified diameter & length options fully cover routine ERCP, ureteroscopic dilation and percutaneous drainage clinical scenarios to improve overall surgical success rate.
These non-vascular guide wires are mainly stocked and used in gastroenterology endoscopy center and urology endoscopy room of tertiary hospitals and specialized digestive disease hospitals. Core applications include ERCP biliary stone drainage, ureteral stricture dilation, percutaneous hepatic abscess drainage and gastrointestinal stricture recanalization under endoscope.
Global medical device distributors purchase full serial specs for bulk supply to community hospitals and private endoscopy clinics to satisfy daily minimally invasive interventional drainage and dilation treatment demands.
All guide wires are EO sterile disposable medical supplies, repeated reuse is forbidden per endoscopic clinical specification to avoid cross infection and lumen foreign body residue.
Zebra straight for unknown irregular stricture exploratory crossing; J superhard wire for duct orifice cannulation such as biliary papilla positioning intubation.
Thin gauge for fine narrow lumen; thicker wire & longer length for deep visceral cavity such as liver percutaneous drainage.
5 years under cool, dry sealed storage away from sharp scratch damage.
