What is the name of a device used during interventional procedures to facilitate catheter placement?

During interventional procedures, a sheath is specifically designed to facilitate catheter placement. This device acts as a protective covering or conduit through which other instruments, such as catheters, can be inserted and advanced into the appropriate vascular structures. By providing a stable and controlled access point, the sheath minimizes trauma to the blood vessels and enhances the efficiency and safety of the procedure.

The sheath allows for the quick exchange of catheters and reduces the need for repeated punctures, thereby improving patient comfort and decreasing the risk of complications. It is an essential tool in various interventional applications, such as angioplasty or stenting, where precise catheter placement is critical for successful outcomes.
