The Terumo Radifocus Introducer II Standard Kit B (REF RS*B40K10MR) is a 4 Fr, 10 cm peripheral introducer sheath kit designed to provide percutaneous access for the introduction of intravascular devices during diagnostic and interventional procedures. The kit combines a hydrophilic-coated sheath with a tapered dilator and a mini guidewire to support smooth vessel entry and reduced insertion resistance.

Key Features
- Sheath size: 4 Fr inner diameter
- Working length: 10 cm
- Hydrophilic M Coat on the sheath surface to reduce friction during insertion and manipulation
- Integrated hemostasis valve to minimize blood loss and air ingress
- Side tube with three-way stopcock for flushing and contrast/medication delivery
- Tapered dilator for a smooth sheath-to-vessel transition
- Kit configuration B including a mini guidewire (as indicated by the MR suffix)
- Sterile, single-use packaging

Clinical Applications
- Percutaneous peripheral arterial or venous access
- Introduction of diagnostic catheters and interventional devices
