Seldinger cannula
A Seldinger cannula is used in percutaneous medical procedures to gain access to a blood vessel, hollow organ, or cavity. The name is derived from the surgeon, Sven-Ivar Seldinger who developed the technique in the 1950’s. A few examples of procedures that utilize the Seldinger technique are angiography, central venous catheterization, drains, pacemaker lead placement, and PEG (Percutaneous Endoscopic Gastrostomy) tubes. The versatility of the cannula for various procedures makes it indispensable for surgeons and doctors.
Customer requirement:
Optimized tip grinding geometry to reduce tissue damage as well as wire and catheter damage. An automated, full, lumen inspection for absolute safety during guide wire and catheter placement.
Our solution:
Our improved bevel grinding geometry prevents punching out during tissue insertion. Further blunting of the cannula eye prevents the Seldinger wire and catheter from scraping when inserted. A fully automated lumen inspection process ensures safe passage of the catheter. A further siliconized coating is applied to the cannula significantly reducing the insertion force required.
