The "Elephant Trunk" technique made easier

Gelweave™ Siena graft for aortic arch and first stage "Elephant Trunk" procedures

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.

Key Features of GelweaveTM Siena

Aortic Arch Plexus

Facilitates individual arch vessel reconstruction2

Ante-Flo Side Branch

Enables lower body reperfusion and earlier patient re-warming4

Radiopaque Markers

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.

GelweaveTM Gelatin Sealant Technology

Vascutek's trusted gelatin sealant technology delivers reduced thrombogenicity while maintaining excellent handling3,5.

Aortic arch and first stage "Elephant Trunk" procedures

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.

MAGNETIC RESONANCE IMAGING SAFETY

Gelweave™ Siena Collared Grafts with Tantalum Radiopaque Markers

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.
