Sel·din·ger tech·nique

(sel'ding-gĕr),
a method of percutaneous insertion of a catheter into a blood vessel or space. A needle is used to puncture the structure and a guide wire is threaded through the needle; when the needle is withdrawn, a catheter is threaded over the wire; the wire is then withdrawn, leaving the catheter in place.

Seldinger technique

A generic eponymous term for any guidewire procedure, named after Swedish radiologist Dr Sven-Ivar Seldinger (1921–1998),  who introduced the procedure in 1953, which allows safe access to blood vessels and hollow organs. Seldinger techniques entail percutaneous puncture with a trocar or needle, tract or vessel dilation as needed, advancement of a guidewire and removal of the trocar. A “sheath” or blunt cannula can then be passed over the guidewire into the cavity or vessel of interest (alternatively, drainage tubes are passed over the guidewire, as in chest drains or nephrostomies); after passing a sheath of tube, the guidewire is withdrawn.
