The properties of ePTFE are known to be less thrombogenic than collagen coated/sealed Dacron® material. Additionally, recently published studies indicate a lower rate of restenosis with GORE ePTFE than with sealed Dacron® material.
To date we have had over 15,000 implantations to include both vascular and pediatric cardiac reconstructions.
No. In fact, the addition of the dense middle layer actually increases the suture retention by approximately 10%.
Surgeons have reported that bleeding times are equivalent if not better than bovine collagen coated/sealed Dacron® material.
Generally patches are stored in the areas where the temperature is cool and thus may stiffen up. To improve handling, allow the patch to warm up (i.e. soaked in warm saline or water), it will soften and be easier to contour.
Increased sealing of suture holes to minimize bleeding. This is achieved by including a middle layer of a proprietary thermoplastic fluoropolymer that has elastic properties.
