The "Elephant Trunk" Technique has been shown to greatly facilitate and reduce the risk of multiple-stage aortic replacement1.
The Gelweave™ Siena graft used in a modified "Elephant Trunk" technique, was conceived to overcome the difficulties and the risks inherent in a large aneurysmal neck1.
Aortic Arch Plexus facilitates individual arch vessel reconstruction2
GelweaveTM technology with excellent handling3
Radiopaque markers facilitate 2nd stage repair1
This film demonstrates GelweaveTM Siena being used for a first stage surgical procedure and a separate stent being used for second stage endovascular completion. Please note: Stent is not included with the GelweaveTM Siena graft.

Facilitates individual arch vessel reconstruction2
Enables lower body reperfusion and earlier patient re-warming4
Radiopaque tantalum markers are located at strategic points along the length of the Gelweave™ Siena graft to facilitate second stage repair either by conventional open vascular or endovascular techniques1.
Vascutek's trusted gelatin sealant technology delivers reduced thrombogenicity while maintaining excellent handling3,5.
A comprehensive range of product designs catering for a variety of both surgical techniques and patient needs when conducting the first stage surgical step of the "Elephant Trunk" technique. The product enables either a second stage surgical or endovascular procedure to be more easily performed.

Gelweave™ vascular prostheses with radiopaque markers were determined to be Magnetic Resonance (MR) conditional. Non-clinical testing determined that prostheses with radiopaque markers were MR conditional. A patient with this prosthesis can be scanned safely, immediately after placement of the prosthesis.
As for the standard branched grafts, the branches are used to accommodate reconstruction of the aortic branch vessels and intra-operative attachment to a perfusion cannula during cardiopulmonary bypass, especially where antegrade as opposed to retrograde perfusion techniques may be preferred.
