What is a vascutek graft?
Device: Vascutek Hybrid Graft. Phase 1 Phase 2. Detailed Description: The Vascutek Hybrid device is designed for use during a frozen elephant trunk procedure. Each system is comprised of a fully sealed traditional prosthesis which is stented at the distal end.
What is Gelweave graft?
Gelweave™ Valsalva is the first aortic root graft in the world, indicated for the repair and substitution of damaged thoracic aorta in cases of aneurysm, dissection and coarctation. It has a unique design, prepared in 3 sections: body, skirt and collar. Category: Cardiac, Vascular and Endovascular.
What is a Valsalva graft?
Vricella. Page 3. Figure 2 The Valsalva graft is a gelatin-impregnated Dacron graft designed to reproduce the anatomic and physiologic features of the normal aortic root. The collar provides anular stabilization, while the skirt simulates the sinuses of Valsalva. Valve-sparing aortic root replacement.
What does Terumo aortic do?
Terumo Aortic is a global medical device company dedicated to developing solutions for aortic and peripheral vascular disease. Our complete portfolio includes the treatment for thoracic, abdominal and peripheral aneurysms, acute and chronic dissections, and peripheral occlusions.
What is a Hemashield graft?
The HEMASHIELD PLATINUM Woven Double Velour Vascular Graft is designed to reduce bleeding at implant and thereby eliminates the operative preclotting step, including cumbersome autoclave techniques. The collagen is designed to be gradually resorbed by the patient.
What is a PTFE graft?
PTFE Grafts PFTE, also known as Teflon, is a synthetic material, readily available. It has been shown that PTFE grafts are easy to implant, cannulate with ease and carry a relatively low rate of infection. PTFE grafts can typically be used for dialysis within 2-3 weeks.
How long does a Hemashield graft last?
The patency rates of the Hemashield-interposed MHV conduits were 88.8% at 3 months, 71.6% at 12 months, and 57.3% at 18 months (Figure 4), and the patency rates in the Hemashield group were found to be superior to those in the Gore-Tex group (p=0.048).
What is a Hemashield graft made of?
HEMASHIELD PLATINUM Woven Double Velour Grafts are collagen-impregnated and come in straight, one-branch, or multi-branch graft configurations for aortic repair. Trusted for more than 20 years, HEMASHIELD grafts are the most used, most studied vascular products available in the market today.
Why is PTFE used for vascular graft?
PTFE vascular graft VascuGraft PTFE features a uniquely flexible, kink-resistant design that is sufficient porous to encourage cellular in-growth, yet offers maximum protection against blood loss, suture pullout, tearing or delamination.
What type of graft is a Hemashield?
What is Hemashield graft?
What kind of graft is a PTFE?
PTFE grafts are the most common type of graft and are considered to be the graft of choice for hemodialysis access around the world. PFTE grafts were first used as a conduit in the late 1970’s. PFTE, also known as Teflon, is a synthetic material, readily available.
What is Hemiarch replacement?
Hemiarch replacement is defined as the proximal arch repair beyond the level of the innominate artery without involving the arch vessels, and total arch replacement is the replacement of supra-aortic vessels as an island or individual branched grafts.
What is PTFE graft used for?
Polytetrafluoroethylene grafts have been used extensively for infrainguinal vascular reconstruction either as the conduit of choice or as a substitute when saphenous vein is unavailable.
What is a PTFE bypass graft?
Polytetrafluoroethylene grafts are the most commonly used synthetic conduits for peripheral arterial bypass procedures although their long-term patency has not been as favorable as AGSV.
How many times can an aortic valve be replaced?
Medical literature suggests the lifespan of the tissue valves used in surgical aortic valve replacement is typically about 10 to 20 years. Since TAVR valves are made of the same biological tissue, it is expected they will have the same longevity.
