| Seldinger technique | A method of percutaneous insertion of a catheter into a blood vessel or space, such as an abscess cavity: a needle is used to puncture the structure and a guide wire is threaded through the needle; when the needle is withdrawn, a catheter is threaded over the wire; the wire is then withdrawn, leaving the catheter in place.
