Introducer sheaths facilitate the insertion of devices such as guidewires and catheters for use in interventional procedures. They are tube-shaped and are generally inserted by nurses. Introducer sheaths can also simplify the application of patches and closure devices at the end of procedures to allow hemostasis to occur. Introducer sheaths are sold in a wide range of sizes to fit patient requirements. They need to have kick resistance and an elongated shape that protects vessels from injuries. In addition, introducer sheaths need to have a transparent structure to allow visualization. They are made with lubricated material to minimize the force and pressure during application. These characteristics make patient management much easier for nurses, and the introduction of devices smoother for doctors.
Introducer sheaths are used for both diagnostic and interventional procedures. In most interventional procedures, an introducer sheath will be used initially and a guiding catheter will be subsequently inserted. However, occasionally the physician will not place an introducer sheath, but directly place a guiding catheter. Guiding catheters (sometimes known as guiding sheaths) are far more expensive than introducer sheaths and are considered as a separate market.
Micro-introducers, or micro-puncture devices, are similar to standard introducer sheaths but with a smaller device diameter. The idea behind micro-introducers is that a small access site is initially used during a procedure. The size of the devices is incrementally increased through this smaller access site, causing the entry point to stretch. When the procedure is completed, the devices are taken out in reverse order and the stretched access site returns to its initial size. This smaller access site means that hemostasis can be achieved at a faster rate than with larger access sites. This effect lessens the total procedure time, frees up hospital beds quicker and improves overall patient satisfaction as they spend less time waiting for a vessel to close. Micro-introducers can be used with both radial and femoral access.
