Development of Introducer Sheath Assembly for Heart Valve Insertion

The present article concerns an introducer sheath for inserting an artificial heart valve into the human body circulatory system. When a sheath is inserted into the wall of a blood vessel, an opening is created through which blood can exit the vessel. Percutaneously placed introducer sheaths allow catheters to be passed into blood vessels. Even after several usage, the introducer sheath is super low-profile, incredibly flexible, kink resistant, and lubricious. The gadget is introduced into the introducer sheath via a temporary ingressive tube. A radiopaque marker is attached to the distal end of the introducer sheath for better visibility during fluoro-imaging. A dilator is included in the introducer sheath to allow access to the introducer sheath via percutaneous vascular access. After a bigger diameter intravascular device is implanted, the sheath features a slit for temporary expansion to return to its previous shape.
