Product Details

Tailored access solutions

A 4F sheath allows for minimally invasive treatment of patients with complex lower limb disease. BIOTRONIK was the first to offer a portfolio for lower limb treatment through a 4F reinforced introducer sheath, combined with 4F and 0.018" guide wire compatible balloon catheters and self-expanding stent systems1 up to 200 mm in length.

Coil Reinforced Sheath

The polymer embedded stainless steel coil shaft provides
flexibility and resistance to kinking and deformation.
The non-ovaling design combined with the PTFE liner are intended to reduce friction on devices passing
through tight anatomical curves.

The Complete 4 F & 6 F Solutions

The availability of 4F, 5F and 6F reinforced introducer sheaths allow a tailored access approach. The BIOTRONIK 6F Solutions portfolio enables treatment through our 6F reinforced introducer sheath
while utilizing our trusted 6F compatible balloon catheters and self-expanding stent systems3, both up to 200 mm in length.

Hydrophobic Coated Sheath

Easy insertion performance2
attributed to the hydrophobic sheath coating in
combination with the smooth tapered
sheath and dilator tip.


Premounted removable
hemostatic valve on the 5F
and 6F introducer sheaths.


Smooth Tapered Tip and Superb Sheath Tip Visibility

The sheath and dilator have
a smooth tapered tip and an
atraumatic tip designed for ease
of insertion.

Angiographic visibility

The platinum alloy marker band
provides tip radiopacity
under fluoroscopic imaging.
