Introducer sheath
Extracted from the Wikipedia article Seldinger technique.
Description
An introducer sheath can be used to introduce catheters or other devices to perform endoluminal (inside the hollow organ) procedures, such as angioplasty. Fluoroscopy may be used to confirm the position of the catheter and to manoeuvre it to the desired location. Injection of radiocontrast may be used to visualize organs. Interventional procedures, such as thermoablation, angioplasty, embolisation or biopsy, may be performed.
